Replace YouTube iframe embeds with clickable thumbnails (#1474)

* Initial plan

* Replace YouTube iframe with clickable thumbnail

- Changed YouTube embed URL from embed format to watch format
- Added ThumbnailUrl property to YouTubeVideoEmbedProjection using YouTube's standard thumbnail URL
- Updated MessageGroupTemplate to render thumbnail image with link instead of iframe
- Updated CSS to style thumbnail appropriately
- Updated test to check for anchor link and thumbnail image instead of iframe

Co-authored-by: Tyrrrz <1935960+Tyrrrz@users.noreply.github.com>

* Address code review feedback

- Use hqdefault.jpg instead of maxresdefault.jpg (guaranteed to exist for all videos)
- Extract thumbnail URL logic to GetThumbnailUrl method for better testability

Co-authored-by: Tyrrrz <1935960+Tyrrrz@users.noreply.github.com>

* Simplify YouTube embed test to focus on data not structure

- Remove checks for HTML structure (class names, nested elements)
- Focus on verifying YouTube URL with correct video ID exists
- Follow same pattern as other embed tests (Spotify, Twitch)

Co-authored-by: Tyrrrz <1935960+Tyrrrz@users.noreply.github.com>

* Fix data-canonical-url and improve test specificity

- Use canonical (non-proxy) URL for data-canonical-url attribute
- Extract thumbnailUrl to local variable to avoid duplicate calls
- Update test to check for img with video ID in src, avoiding false positives
- Test now verifies the actual thumbnail data rather than any link

Co-authored-by: Tyrrrz <1935960+Tyrrrz@users.noreply.github.com>

* Inline thumbnail URL logic directly into attributes

- Remove GetThumbnailUrl method from YouTubeVideoEmbedProjection
- Remove local variables from template
- Put coalescing logic directly in src and data-canonical-url attributes

+# Docker usage instructions
+
+Docker distribution of DiscordChatExporter provides a way to run the app in a virtualized and isolated environment. Due to the nature of Docker, you also don't need to install any prerequisites otherwise required by DCE.
+
+> **Note**:
+> Only the CLI flavor of DiscordChatExporter is available for use with Docker.
+
+## Pulling
+
+This will download the [Docker image from the registry](https://hub.docker.com/r/tyrrrz/discordchatexporter) to your computer. You can run this command again to update when a new version is released.
+
+```console
+$ docker pull tyrrrz/discordchatexporter:stable
+```
+
+Note the `:stable` tag. DiscordChatExporter images are tagged according to the following patterns:
+
+- `stable` — latest stable version release. This tag is updated with each release of a new project version. Recommended for personal use.
+- `x.y.z` (e.g. `2.30.1`) — specific stable version release. This tag is pushed when the corresponding version is released and never updated thereafter. Recommended for use in automation scenarios.
+- `latest` — latest (potentially unstable) build. This tag is updated with each new commit to the `master` branch. Not recommended, unless you want to test a new feature that has not been released in a stable version yet.
+
+You can see all available tags [here](https://hub.docker.com/r/tyrrrz/discordchatexporter/tags?ordering=name).
+
+## Usage
+
+To run the CLI in Docker and render help text:
+
+```console
+$ docker run --rm tyrrrz/discordchatexporter:stable
+```
+
+To export a channel:
+
+```console
+$ docker run --rm -v /path/on/machine:/out tyrrrz/discordchatexporter:stable export -t TOKEN -c CHANNELID
+```
+
+If you want colored output and real-time progress reporting, pass the `-it` (interactive + pseudo-terminal) option:
+
+```console
+$ docker run --rm -it -v /path/on/machine:/out tyrrrz/discordchatexporter:stable export -t TOKEN -c CHANNELID
+```
+
+The `-v /path/on/machine:/out` option instructs Docker to bind the `/out` directory inside the container to a path on your host machine. Replace `/path/on/machine` with the directory you want the files to be saved at.
+
+> **Note**:
+> If you are running SELinux, you will need to add the `:z` option after `/out`, e.g.:
+>
+> ```console
+> $ docker run --rm -v /path/on/machine:/out:z tyrrrz/discordchatexporter:stable export -t TOKEN -c CHANNELID
+> ```
+>
+> For more information, refer to the [Docker docs SELinux labels for bind mounts page](https://docs.docker.com/storage/bind-mounts/#configure-the-selinux-label).
+
+You can also use the current working directory as the output directory by specifying:
+
+- `-v $PWD:/out` in Bash
+- `-v $pwd.Path:/out` in PowerShell
+
+For more information, please refer to the [Dockerfile](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/DiscordChatExporter.Cli.dockerfile) and [Docker documentation](https://docs.docker.com/engine/reference/run).
+
+To get your Token and Channel IDs, please refer to [this page](Token-and-IDs.md).
+
+## Unix permissions issues
+
+This image was designed with a user running as uid:gid of 1000:1000.
+
+If your current user has different IDs, and you want to generate files directly editable for your user, you might want to run the container like this:
+
+```console
+$ mkdir data # or chown -R $(id -u):$(id -g) data
+$ docker run -it --rm -v $PWD/data:/out --user $(id -u):$(id -g) tyrrrz/discordchatexporter:stable export -t TOKEN -g CHANNELID
+```
+
+## Environment variables
+
+DiscordChatExpoter CLI accepts the `DISCORD_TOKEN` environment variable as a fallback for the `--token` option. You can set this variable either with the `--env` Docker option or with a combination of the `--env-file` Docker option and a `.env` file.
+
+Please refer to the [Docker documentation](https://docs.docker.com/engine/reference/commandline/run/#set-environment-variables--e---env---env-file) for more information.

+# Getting started
+
+Welcome to the getting started page!
+Here you'll learn how to use every **DiscordChatExporter** (DCE for short) feature.
+For other things you can do with DCE, check out the [Guides](Readme.md#guides) section.
+
+If you still have unanswered questions after reading this page or if you have encountered a problem, please visit our [FAQ & Troubleshooting](Troubleshooting.md) section.
+
+The information presented on this page is valid for **all** platforms.
+
+## GUI or CLI?
+
+![GUI vs CLI](https://i.imgur.com/j9OTxRB.png)
+
+**DCE** has two different versions:
+
+- **Graphical User Interface** (**GUI**) - it's the preferred version for newcomers as it is easy to use.
+  You can get it by [downloading](https://github.com/Tyrrrz/DiscordChatExporter/releases/latest) the `DiscordChatExporter.*.zip` file.
+- **Command-line Interface** (**CLI**) - offers greater flexibility and more features for advanced users, such as export scheduling, ID lists, and more specific date ranges.
+  You can get it by [downloading](https://github.com/Tyrrrz/DiscordChatExporter/releases/latest) the `DiscordChatExporter.Cli.*.zip` file.
+
+There are dedicated guides for each version:
+
+- [Using the GUI](Using-the-GUI.md)
+- [Using the CLI](Using-the-CLI.md)
+
+## File formats
+
+### HTML
+
+![](https://i.imgur.com/S7lBTkV.png)
+The HTML format replicates Discord's interface, making it the most user-friendly option.
+It's the best format for attachment preview and sharing.
+You can open `.html` files with a web browser, such as Google Chrome.
+
+> [!WARNING]
+> If a picture is deleted, or if a user changes its avatar, the respective images will no longer be displayed.
+> Export using the "Download assets" (`--media`) option to avoid this.
+
+### Plain Text
+
+<img src="https://i.imgur.com/PbUyRXD.png" height="400"/>
+
+The Plain Text format formats messages as plain text, and has the smallest size.
+You can open `.txt` files with a text editor, such as Notepad.
+
+### JSON
+
+<img src="https://i.imgur.com/FAeSA4O.png" height="400"/>
+
+The JSON format contains more technical information and is easily parsable.
+You can open `.json` files with a text editor, such as Notepad.
+
+### CSV
+
+![](https://i.imgur.com/VEVUsKs.png)
+![](https://i.imgur.com/1vPmQqQ.png)
+
+The CSV format allows for easy parsing of the chat log. Depending on your needs, the JSON format might be better.
+You can open `.csv` files with a text editor, such as Notepad, or a spreadsheet app, like Microsoft Excel and Google Sheets.

+# Message filters
+
+You can use a special notation to filter messages that you want to have included in an export. The notation syntax is designed to mimic Discord's search query syntax, but with additional capabilities.
+
+To configure a filter, specify it in advanced export parameters when using the GUI or by passing the `--filter` option when using the CLI. For the CLI version, see also [caveats](#cli-caveats).
+
+## Examples
+
+- Filter by user
+
+```console
+from:Tyrrrz
+```
+
+- Filter by user (with discriminator)
+
+```console
+from:Tyrrrz#1234
+```
+
+- Filter by message content (allowed values: `link`, `embed`, `file`, `video`, `image`, `sound`)
+
+```console
+has:image
+```
+
+- Filter by mentioned user (same rules apply as with `from:` filter)
+
+```console
+mentions:Tyrrrz#1234
+```
+
+- Filter by contained text (has word "hello" and word "world" somewhere in the message text):
+
+```console
+hello world
+```
+
+- Filter by contained text (has the string "hello world" somewhere in the message text):
+
+```console
+"hello world"
+```
+
+- Combine multiple filters ('and'):
+
+```console
+from:Tyrrrz has:image
+```
+
+- Same thing but with an explicit operator:
+
+```console
+from:Tyrrrz & has:image
+```
+
+- Combine multiple filters ('or'):
+
+```console
+from:Tyrrrz | from:"96-LB"
+```
+
+- Combine multiple filters using groups:
+
+```console
+(from:Tyrrrz | from:"96-LB") has:image
+```
+
+- Negate a filter:
+
+```console
+-from:Tyrrrz | -has:image
+```
+
+- Negate a grouped filter:
+
+```console
+-(from:Tyrrrz has:image)
+```
+
+- Escape special characters (`-` is escaped below, so it's not parsed as negation operator):
+
+```console
+from:96\-LB
+```
+
+## CLI Caveats
+
+In most cases, you will need to enclose your filter in quotes (`"`) to escape characters that may have special meaning in your shell:
+
+```console
+$ ./DiscordChatExporter.Cli export [...] --filter "from:Tyrrrz has:image"
+```
+
+If you need to include quotes inside the filter itself as well, use single quotes (`'`) for those instead:
+
+```console
+$ ./DiscordChatExporter.Cli export [...] --filter "from:Tyrrrz 'hello world'"
+```
+
+Additionally, negated filters (those that start with `-`) may cause parsing issues even when enclosed in quotes. To avoid this, use the tilde (`~`) character instead of the dash (`-`):
+
+```console
+$ ./DiscordChatExporter.Cli export [...] --filter ~from:Tyrrrz
+```

+# Scheduling exports with Cron
+
+## Creating the script
+
+1. Open Terminal and create a new text file with `nano /path/to/DiscordChatExporter/cron.sh`
+
+> **Note**:
+> You can't use your mouse in nano, use the arrow keys to control the cursor (caret).
+
+2. Paste the following into the text file:
+
+```bash
+#!/bin/bash
+# Info: https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs
+
+TOKEN=tokenhere
+CHANNELID=channelhere
+DLLFOLDER=dceFOLDERpathhere
+FILENAME=filenamehere
+EXPORTDIRECTORY=dirhere
+EXPORTFORMAT=formathere
+# Available export formats: plaintext, htmldark, htmllight, json, csv
+# /\ CaSe-SeNsItIvE /\
+# You can edit the export command on line 40 if you'd like to include more options like date ranges and date format. You can't use partitioning (-p) with this script.
+
+# This will verify if EXPORTFORMAT is valid and will set the final file extension according to it. If the format is invalid, the script will display a message and exit.
+if [[ "$EXPORTFORMAT" == "plaintext" ]]; then
+FORMATEXT=.txt
+elif [[ "$EXPORTFORMAT" == "htmldark" ]] || [[ "$EXPORTFORMAT" == "htmllight" ]]; then
+FORMATEXT=.html
+elif [[ "$EXPORTFORMAT" == "json" ]]; then
+FORMATEXT=.json
+elif [[ "$EXPORTFORMAT" == "csv" ]]; then
+FORMATEXT=.csv
+else
+echo "$EXPORTFORMAT - Unknown export format"
+echo "Available export formats: plaintext, htmldark, htmllight, csv, json"
+echo "/\ CaSe-SeNsItIvE /\\"
+exit 1
+fi
+
+# This will change the script's directory to DLLPATH, if unable to do so, the script will exit.
+cd $DLLFOLDER || exit 1
+
+# This will export your chat
+./DiscordChatExporter.Cli export -t $TOKEN -c $CHANNELID -f $EXPORTFORMAT -o $FILENAME.tmp
+
+# This sets the current time to a variable
+CURRENTTIME=$(date +"%Y-%m-%d-%H-%M-%S")
+
+# This will move the .tmp file to the desired export location, if unable to do so, it will attempt to delete the .tmp file.
+if ! mv "$FILENAME.tmp" "${EXPORTDIRECTORY//\"}/$FILENAME-$CURRENTTIME$FORMATEXT" ; then
+echo "Unable to move $FILENAME.tmp to $EXPORTDIRECTORY/$FILENAME-$CURRENTTIME$FORMATEXT."
+echo "Cleaning up..."
+  if ! rm -Rf "$FILENAME.tmp" ; then
+  echo "Unable to remove $FILENAME.tmp."
+  fi
+exit 1
+fi
+exit 0
+```
+
+3. Replace:
+
+- `tokenhere` with your [Token](Token-and-IDs.md).
+- `channelhere` with a [Channel ID](Token-and-IDs.md).
+- `dceFOLDERpathhere` with DCE's **directory path** (e.g. `/path/to/folder`, NOT `/path/to/folder/DiscordChatExporter.dll`).
+- `filenamehere` with the exported channel's filename, without spaces.
+- `dirhere` with the export directory (e.g. /home/user/Documents/Discord\ Exports).
+- `formathere` with one of the available export formats.
+
+> **Note**:
+> Remember to escape spaces (add `\` before them) or to quote (") the paths (`"/home/my user"`)!
+
+> **Note**:
+> To save, hold down CTRL and then press O, if asked for a filename, type it and press ENTER. Hit CTRL+X to exit the text editor.
+> [Check out this page](https://wiki.gentoo.org/wiki/Nano/Basics_Guide) if you want to know more about nano.
+
+4. Make your script executable with `chmod +x /path/to/DiscordChatExporter/cron.sh`
+
+5. Let's edit the cron file. If you want to run the script with your user privileges, edit it by running `crontab -e`. If you want to run the script as root, edit it with `sudo crontab -e`. If this is your first time running this command, you might be asked to select a text editor. Nano is easier for beginners.
+
+6. Add the following to the end of the file `* * * * * /path/to/DiscordChatExporter/cron.sh >/tmp/discordchatexporter.log 2>/tmp/discordchatexportererror.log`. Don't forget to replace the `/path/to/DiscordChatExporter/cron.sh`!
+
+> **Note**:
+> If you don't want logs to be created, replace both `/tmp/discordchatexporter.log` with `/dev/null`.
+
+Then replace the \*s according to:
+
+![](https://i.imgur.com/RY7USM6.png)
+
+---
+
+**Examples**:
+
+- If you want to execute the script at minute 15 of every hour: `15 * * * *`
+- Every 30 minutes `*/30 * * * *`
+- Every day at midnight `0 0 * * *`
+- Every day at noon `0 12 * * *`
+- Every day at 3, 4 and 6 PM `0 15,16,18 * * *`
+- Every Wednesday at 9 AM `0 9 * * 3`
+
+Verify your cron time [here](https://crontab.guru).
+
+---
+
+**Additional information**
+
+The week starts on Sunday. 0 = SUN, 1 = MON ... 7 = SUN.
+
+Be aware that if you set the day to '31', the script will only run on months that have the 31st day.
+
+> [Learn more about running a cron job on the last day of the month here](https://stackoverflow.com/questions/6139189/cron-job-to-run-on-the-last-day-of-the-month) (expert).
+
+The default filename for the exported channel is `YYYY-MM-DD-hh-mm-ss-yourfilename`. You can change it if you'd like.
+
+Don't forget to update your token in the script after it has been reset!

+
+## Creating the .plist file
+
+Open TextEdit, make a Plain Text (⇧⌘T) and then paste the following into it:

+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
+<plist version="1.0">
+  <dict>
+    <key>Label</key>
+    <string>local.discordchatexporter</string>
+    <key>Program</key>
+    <string>/path/to/filename.sh</string>
+    REPLACEME
+  </dict>
+</plist>
+```
+
+- The `Label` string is the name of the export job, it must be something unique. Replace the `local.discordchatexporter` between the `<string>` with another name if you'd like to run more than one script.
+- The `Program` string is the path to the script. Replace `/path/to/filename.sh` between the `<string>` with the path of the previously created script.
+- Replace the `REPLACEME` with the content presented in the following sections according to <u>when</u> you want to export.
+
+When you're done, save the file with the same name as the `Label` and with the `.plist` extension (not `.txt`), like `local.discordchatexporter.plist`.
+
+### Exporting on System Boot/User Login
+
+```xml
+<key>RunAtLoad</key>
+<true/>
+```
+
+### Export every _n_ seconds
+
+The following example is to export every 3600 seconds (1 hour), replace the integer value with your desired time:
+
+```xml
+<key>StartInterval</key>
+<integer>3600</integer>
+```
+
+### Export at a specific time and date
+
+```xml
+<key>StartCalendarInterval</key>
+<dict>
+  <key>Weekday</key>
+  <integer>0</integer>
+  <key>Month</key>
+  <integer>0</integer>
+  <key>Day</key>
+  <integer>0</integer>
+  <key>Hour</key>
+  <integer>0</integer>
+  <key>Minute</key>
+  <integer>0</integer>
+</dict>
+```
+
+| Key         | Integer           |
+| ----------- | ----------------- |
+| **Month**   | 1-12              |
+| **Day**     | 1-31              |
+| **Weekday** | 0-6 (0 is Sunday) |
+| **Hour**    | 0-23              |
+| **Minute**  | 0-59              |
+
+**Sunday** - 0; **Monday** - 1; **Tuesday** - 2; **Wednesday** - 3; **Thursday** - 4; **Friday** - 5; **Saturday** - 6
+
+Replace the template's `0`s according to the desired times.
+
+You can delete the `<key>`s you don't need, don't forget to remove the `<integer>0</integer>` under it.
+Omitted keys are interpreted as wildcards, for example, if you delete the Minute key, the script will run at every minute, delete the Weekday key and it'll run at every weekday, and so on.
+
+Be aware that if you set the day to '31', the script will only run on months that have the 31st day.
+
+**Check the examples below ([or skip to step 3 (loading the file)](#3-loading-the-plist-into-launchctl)):**
+
+Export everyday at 5:15 PM:
+
+```xml
+<key>StartCalendarInterval</key>
+<dict>
+  <key>Hour</key>
+  <integer>17</integer>
+  <key>Minute</key>
+  <integer>15</integer>
+</dict>
+
+```
+
+Every 15 minutes of an hour (xx:15):
+
+```xml

+## Loading the .plist into launchctl
+
+1. Copy your `filename.plist` file to one of these folders according to how you want it to run:
+
+- `~/Library/LaunchAgents` runs as the current logged-in user.
+
+- `/Library/LaunchDaemons` runs as the system "_administrator_" (root).
+
+- If macOS has a single user:
+  - If you want to export only when the user is logged in, choose the first one.
+  - If you want the script to always run on System Startup, choose the second one.
+- If macOS has multiple users:
+  - If you want the script to run only when a certain user is logged in, choose the first one.
+  - If you want the script to always run on System Startup, choose the second one.
+
+To quickly go to these directories, open Finder and press Command+Shift+G (⌘⇧G), then paste the path into the text box.
+
+2. To load the job into launchctl, in Terminal, type `launchctl load`, press SPACE, drag and drop the `.plist` into the Terminal window, then hit RETURN. It won't output anything if it was successfully loaded.
+
+### Extra launchctl commands
+
+**Unloading a job**
+
+```
+launchctl unload /path/to/Library/LaunchAgents/local.discordchatexporter.plist
+```
+
+**List every loaded job**
+
+```
+launchctl list
+```
+
+**Check if a specific job is enabled**
+You can also see error codes (2nd number) by running this command.
+
+```
+launchctl list | grep local.discordchatexporter
+```

+# Scheduling exports on Windows
+
+## Creating the script
+
+1. Open a text editor such as Notepad and paste:
+
+```console
+# Info: https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs
+
+$TOKEN = "tokenhere"
+$CHANNEL = "channelhere"
+$EXEPATH = "exefolderhere"
+$FILENAME = "filenamehere"
+$EXPORTDIRECTORY = "dirhere"
+$EXPORTFORMAT = "formathere"
+# Available export formats: PlainText, HtmlDark, HtmlLight, Json, Csv
+
+cd $EXEPATH
+
+./DiscordChatExporter.Cli export -t $TOKEN -c $CHANNEL -f $EXPORTFORMAT -o "$FILENAME.tmp"
+
+$Date = Get-Date -Format "yyyy-MM-dd-HH-mm"
+
+If($EXPORTFORMAT -match "PlainText"){mv "$FILENAME.tmp" -Destination "$EXPORTDIRECTORY\$FILENAME-$Date.txt"}
+ElseIf($EXPORTFORMAT -match "HtmlDark"){mv "$FILENAME.tmp" -Destination "$EXPORTDIRECTORY\$FILENAME-$Date.html"}
+ElseIf($EXPORTFORMAT -match "HtmlLight"){mv "$FILENAME.tmp" -Destination "$EXPORTDIRECTORY\$FILENAME-$Date.html"}
+ElseIf($EXPORTFORMAT -match "Json"){mv "$FILENAME.tmp" -Destination "$EXPORTDIRECTORY\$FILENAME-$Date.json"}
+ElseIf($EXPORTFORMAT -match "Csv"){mv "$FILENAME.tmp" -Destination "$EXPORTDIRECTORY\$FILENAME-$Date.csv"}
+exit
+```
+
+2. Replace:
+
+- `tokenhere` with your [Token](Token-and-IDs.md)
+- `channelhere` with a [Channel ID](Token-and-IDs.md)
+- `exefolderhere` with the .exe **directory's path** (e.g. C:\Users\User\Desktop\DiscordChatExporter)
+- `filenamehere` with a filename without spaces
+- `dirhere` with the export directory (e.g. C:\Users\User\Documents\Exports)
+- `formathere` with one of the available export formats
+
+Make sure not to delete the quotes (")
+
+3. Save the file as `filename.ps1`, not as `.txt`
+
+> **Note**: You can also modify the script to use other options, such as `include-threads` or switch to a different command, e. g. `exportguild`.
+
+## Export at Startup
+
+1. Press Windows + R, type `shell:startup` and press ENTER
+2. Paste `filename.ps1` or a shortcut into this folder
+
+## Scheduling with Task Scheduler
+
+Please note that your computer must be turned on for the export to happen.
+
+1. Press Windows + R, type `taskschd.msc` and press ENTER
+2. Select `Task Scheduler Library`, create a Basic Task, and follow the instructions on-screen
+

+
+## How to export with a bot token
+
+### Step 1 - Create an application
+
+You can create a new application or use an existing one. If you want to create a new one:
+
+1. Go to [Discord developer portal](https://discord.com/developers/applications)
+2. Click on **New Application** in the top right corner
+3. Enter a name for your application and click **Create**
+
+### Step 2 - Invite the bot to your server
+
+The bot needs to be invited to the server you'd like to export from.
+
+1. Go to [Discord developer portal](https://discord.com/developers/applications)
+2. Navigate to **General Information** on the left
+3. Copy the **Application ID**
+4. Open the following URL in your browser, replacing `YOUR_APP_ID` with the copied Client ID:
+
+<!-- Permission code 66560 corresponds to "View Channels" and "Read Message History" permissions.
+      User can uncheck these when adding the bot to their server. -->
+
+```
+https://discord.com/oauth2/authorize?scope=bot&permissions=66560&client_id=YOUR_APP_ID
+```
+
+### Step 3 - Ensure message content intent is enabled
+
+If this option is not enabled, the exported files will be empty.
+
+1. Go to [Discord developer portal](https://discord.com/developers/applications)
+2. Open your Application's settings
+3. Navigate to the **Bot** section on the left
+4. Scroll down to the **Privileged Gateway Intents** section
+5. Enable **Message Content Intent** by toggling the switch
+
+<img width="500" align="right" src="https://i.imgur.com/PPm2KKn.png" />
+
+### Step 4 - Copy the bot token
+
+If you don't have a bot token yet or if you've lost it, follow these steps to reset it:
+
+1. Go to [Discord developer portal](https://discord.com/developers/applications)
+2. Open your Application's settings
+3. Navigate to the **Bot** section on the left
+4. Under **Token** click **Reset Token**
+5. Click **Yes, do it!** and authenticate to confirm
+
+> **Tip**:
+> As the token is only shown once, make sure to store it in a safe place. If you lose the token, you will have to reset it again.
+
+> [!WARNING]
+> Resetting the token will invalidate the old one. Any integrations relying on the old token will cease to function until they are updated.

+# Troubleshooting
+
+Welcome to the Frequently Asked Questions (FAQ) and Troubleshooting page!
+Here you'll find the answers to most of the questions related to **DiscordChatExporter** (DCE for short) and its core features.
+
+- ❓ If you still have unanswered questions _after_ reading this page, feel free to [create a new discussion](https://github.com/Tyrrrz/DiscordChatExporter/discussions/new).
+- 🐞 If you have encountered a problem that's not described here, has not [been discussed before](https://github.com/Tyrrrz/DiscordChatExporter/discussions), and is not a [known issue](https://github.com/Tyrrrz/DiscordChatExporter/issues?q=is%3Aissue), please [create a new discussion](https://github.com/Tyrrrz/DiscordChatExporter/discussions/new) or [open a bug report](https://github.com/Tyrrrz/DiscordChatExporter/issues/new). Don't forget to include your platform (Windows, Mac, Linux, etc.) and a detailed description of your question/problem.
+
+## General questions
+
+### Token stealer?
+
+No. That's why this kind of software needs to be open-source, so the code can be audited by anyone.
+Your token is only used to connect to Discord's API, it's not sent anywhere else.
+If you're using the GUI, be aware that your token will be saved to a plain text file unless you disable it in the settings menu.
+
+### Why should I be worried about the safety of my token?
+
+A token can be used to log into your account, so treat it like a password and never share it.
+
+### How can I reset my token?
+
+Follow the [instructions here](Token-and-IDs.md).
+
+### Will I get banned if I use this?
+
+Automating user accounts is technically against [TOS](https://discord.com/terms), use at your discretion. [Bot accounts](https://discord.com/developers/docs/topics/oauth2#bot-users) don't have this restriction.
+
+### Will the messages disappear from the exported file if I delete a message, delete my account or block a person?
+
+Text messages will not be removed from the exported file, but if media, such as images and user avatars, is changed or deleted, it will no longer be displayed. To avoid this, export using the "Download media" (`--media`) option.
+
+### Can DCE export messages that have already been deleted?
+
+No, DCE cannot access them since they have been permanently deleted from Discord's servers.
+
+### Can DCE export private chats?
+
+Yes, if your account has access to them.
+
+### Can DCE download images?
+
+Yes, and other media too. Export using the "Download media" (`--media`) option.
+
+### Can the exported chats be shared?
+
+Yes.
+
+### Can DCE export multiple formats at once?
+
+No, you can only export one format at a time.
+
+### Can DCE recreate the exported chats in Discord?
+
+No, DCE is an exporter.
+
+### Can DCE reupload exported messages to another channel?
+
+No, DCE is an exporter.
+
+### Can DCE add new messages to an existing export?
+
+No.
+
+## First steps
+
+### How can I find my token?
+
+Check the following page: [Obtaining token](Token-and-IDs.md)
+
+### When I open DCE a black window pops up quickly or nothing shows up
+
+You might have downloaded the CLI flavor of the app, which is meant to be run in a terminal. Try [downloading the GUI](Getting-started.md#gui-or-cli) instead if that's what you want.
+
+### How can I set DCE to export automatically at certain times?
+
+Check the following pages to learn how to schedule **DiscordChatExporter.CLI** runs (advanced):
+
+- [Windows scheduling](Scheduling-Windows.md)
+- [macOS scheduling](Scheduling-MacOS.md)
+- [Linux scheduling](Scheduling-Linux.md)
+
+### The exported file is too large, I can't open it
+
+Try opening it with a different program, try partitioning or use a different file format, like `PlainText`.
+
+### I see messages in the export, but they have no content
+
+Your bot is missing the 'Message Content Intent'. Go to the [Discord Developer Portal](https://discord.com/developers/applications), navigate to the 'Bot' section and enable it.
+
+## CLI
+
+### How do I use the CLI?
+
+Check the following page:
+
+- [Using the CLI](Using-the-CLI.md)
+
+If you're using **Docker**, please refer to the [Docker Usage Instructions](Docker.md) instead.
+
+### Where can I find the 'Channel IDs'?
+
+Check the following page:
+
+- [Obtaining Channel IDs](Token-and-IDs.md)
+
+### I can't find Docker exported chats
+
+Check the following page:
+
+- [Docker usage instructions](Docker.md)
+
+### I can't export Direct Messages
+
+Make sure you're [copying the DM Channel ID](Token-and-IDs.md#how-to-get-a-direct-message-channel-id), not the person's user ID.
+
+## Errors
+
+```yml
+DiscordChatExporter.Domain.Exceptions.DiscordChatExporterException: Authentication token is invalid.

+# Using the CLI
+
+## Step 1
+
+After extracting the `.zip` archive, open your preferred terminal.
+
+## Step 2
+
+Change the current directory to DCE's folder with `cd C:\path\to\DiscordChatExporter` (`cd /path/to/DiscordChatExporter` on **MacOS** and **Linux**), then press ENTER to run the command.
+
+**Windows** users can quickly get the folder's path by clicking the address bar while inside the folder.
+![Copy path from Explorer](https://i.imgur.com/XncnhC2.gif)
+
+**macOS** users can press Command+Option+C (⌘⌥C) while inside the folder (or selecting it) to copy its path to the clipboard.
+
+You can also drag and drop the folder on **every platform**.
+![Drag and drop folder](https://i.imgur.com/sOpZQAb.gif)
+
+## Step 3
+
+Now we're ready to run the commands.
+
+Type the following command in your terminal of choice, then press ENTER to run it. This will list all available subcommands and options.
+
+```console
+./DiscordChatExporter.Cli
+```
+
+> **Note**:
+> On Windows, if you're using the default Command Prompt (`cmd`), omit the leading `./` at the start of the command.
+
+
+> **Docker** users, please refer to the [Docker usage instructions](Docker.md).
+
+## CLI commands
+
+| Command                 | Description                                          |
+|-------------------------|------------------------------------------------------|
+| export                  | Exports a channel                                    |
+| exportdm                | Exports all direct message channels                  |
+| exportguild             | Exports all channels within the specified server     |
+| exportall               | Exports all accessible channels                      |
+| channels                | Outputs the list of channels in the given server     |
+| dm                      | Outputs the list of direct message channels          |
+| guilds                  | Outputs the list of accessible servers               |
+| guide                   | Explains how to obtain token, server, and channel ID |
+
+To use the commands, you'll need a token. For the instructions on how to get a token, please refer to [this page](Token-and-IDs.md), or run `./DiscordChatExporter.Cli guide`.
+
+To get help with a specific command, run:
+
+```console
+./DiscordChatExporter.Cli command --help
+```
+
+For example, to figure out how to use the `export` command, run:
+
+```console
+./DiscordChatExporter.Cli export --help
+```
+
+## Export a specific channel
+
+You can quickly export with DCE's default settings by using just `-t token` and `-c channelid`.
+
+```console
+./DiscordChatExporter.Cli export -t "mfa.Ifrn" -c 53555
+```
+
+#### Changing the format
+
+You can change the export format to `HtmlDark`, `HtmlLight`, `PlainText` `Json` or `Csv` with `-f format`. The default
+format is `HtmlDark`.
+
+```console
+./DiscordChatExporter.Cli export -t "mfa.Ifrn" -c 53555 -f Json
+```
+
+#### Changing the output filename
+
+You can change the filename by using `-o name.ext`. e.g. for the `HTML` format:
+
+```console
+./DiscordChatExporter.Cli export -t "mfa.Ifrn" -c 53555 -o myserver.html
+```
+
+#### Changing the output directory
+
+You can change the export directory by using `-o` and providing a path that ends with a slash or does not have a file
+extension.
+If any of the folders in the path have a space in its name, escape them with quotes (").
+
+```console
+./DiscordChatExporter.Cli export -t "mfa.Ifrn" -c 53555 -o "C:\Discord Exports"
+```
+
+#### Changing the filename and output directory
+
+You can change both the filename and export directory by using `-o directory\name.ext`.
+Note that the filename must have an extension, otherwise it will be considered a directory name.
+If any of the folders in the path have a space in its name, escape them with quotes (").
+
+```console
+./DiscordChatExporter.Cli export -t "mfa.Ifrn" -c 53555 -o "C:\Discord Exports\myserver.html"
+```
+
+#### Generating the filename and output directory dynamically
+
+You can use template tokens to generate the output file path based on the server and channel metadata.
+
+```console
+./DiscordChatExporter.Cli export -t "mfa.Ifrn" -c 53555 -o "C:\Discord Exports\%G\%T\%C.html"
+```
+
+Assuming you are exporting a channel named `"my-channel"` in the `"Text channels"` category from a server
+called `"My server"`, you will get the following output file
+path: `C:\Discord Exports\My server\Text channels\my-channel.html`
+
+Here is the full list of supported template tokens:
+
+- `%g` - server ID
+- `%G` - server name
+- `%t` - category ID
+- `%T` - category name
+- `%c` - channel ID
+- `%C` - channel name
+- `%p` - channel position
+- `%P` - category position
+- `%a` - the "after" date
+- `%b` - the "before" date
+- `%d` - the current date
+- `%%` - escapes `%`
+
+#### Partitioning
+
+You can use partitioning to split files after a given number of messages or file size.
+For example, a channel with 36 messages set to be partitioned every 10 messages will output 4 files.
+
+```console
+./DiscordChatExporter.Cli export -t "mfa.Ifrn" -c 53555 -p 10
+```
+
+A 45 MB channel set to be partitioned every 20 MB will output 3 files.
+
+```console
+./DiscordChatExporter.Cli export -t "mfa.Ifrn" -c 53555 -p 20mb
+```
+
+#### Downloading assets
+
+If this option is set, the export will include additional files such as user avatars, attached files, images, etc.
+Only files that are referenced by the export are downloaded, which means that, for example, user avatars will not be
+downloaded when using the plain text (TXT) export format.
+A folder containing the assets will be created along with the exported chat. They must be kept together.
+
+```console
+./DiscordChatExporter.Cli export -t "mfa.Ifrn" -c 53555 --media
+```
+
+#### Reusing assets
+
+Previously downloaded assets can be reused to skip redundant downloads as long as the chat is always exported to the
+same folder. Using this option can speed up future exports. This option requires the `--media` option.
+
+```console
+./DiscordChatExporter.Cli export -t "mfa.Ifrn" -c 53555 --media --reuse-media
+```
+
+#### Changing the media directory
+
+By default, the media directory is created alongside the exported chat. You can change this by using `--media-dir` and
+providing a path that ends with a slash. All of the exported media will be stored in this directory.
+
+```console
+./DiscordChatExporter.Cli export -t "mfa.Ifrn" -c 53555 --media --media-dir "C:\Discord Media"
+```
+
+#### Changing the date format
+
+You can customize how dates are formatted in the exported files by using `--locale` and inserting one of Discord's
+locales. The default locale is `en-US`.
+
+```console
+./DiscordChatExporter.Cli export -t "mfa.Ifrn" -c 53555 --locale "de-DE"
+```
+
+#### Date ranges
+
+**Messages sent before a date**
+Use `--before` to export messages sent before the provided date. E.g. messages sent before September 18th, 2019:
+
+```console
+./DiscordChatExporter.Cli export -t "mfa.Ifrn" -c 53555 --before 2019-09-18
+```
+
+**Messages sent after a date**
+Use `--after` to export messages sent after the provided date. E.g. messages sent after September 17th, 2019 11:34 PM:
+
+```console
+./DiscordChatExporter.Cli export -t "mfa.Ifrn" -c 53555 --after "2019-09-17 23:34"
+```
+
+**Messages sent in a date range**
+Use `--before` and `--after` to export messages sent during the provided date range. E.g. messages sent between
+September 17th, 2019 11:34 PM and September 18th:
+
+```console
+./DiscordChatExporter.Cli export -t "mfa.Ifrn" -c 53555 --after "2019-09-17 23:34" --before "2019-09-18"
+```
+
+You can try different formats like `17-SEP-2019 11:34 PM` or even refine your ranges down to
+milliseconds `17-SEP-2019 23:45:30.6170`!
+Don't forget to quote (") the date if it has spaces!
+More info about .NET date
+formats [here](https://docs.microsoft.com/en-us/dotnet/standard/base-types/custom-date-and-time-format-strings).
+
+#### Filtering messages
+
+Use `--filter` to filter what messages are included in the export.
+
+```console
+./DiscordChatExporter.Cli export -t "mfa.Ifrn" -c 53555 --filter "from:Tyrrrz has:image"
+```
+
+Documentation on message filter syntax can be found [here](https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs/Message-filters.md).
+
+### Export channels from a specific server
+
+To export all channels in a specific server, use the `exportguild` command and provide the server ID through the `-g|--guild` option:
+
+```console
+./DiscordChatExporter.Cli exportguild -t "mfa.Ifrn" -g 21814
+```
+
+#### Including threads
+
+By default, threads are not included in the export. You can change this behavior by using `--include-threads` and
+specifying which threads should be included. It has possible values of `none`, `active`, or `all`, indicating which
+threads should be included. To include both active and archived threads, use `--include-threads all`.
+
+```console
+./DiscordChatExporter.Cli exportguild -t "mfa.Ifrn" -g 21814 --include-threads all
+```
+
+#### Including voice channels
+
+By default, voice channels are included in the export. You can change this behavior by using `--include-vc` and
+specifying whether to include voice channels in the export. It has possible values of `true` or `false`, to exclude
+voice channels, use `--include-vc false`.
+
+```console
+./DiscordChatExporter.Cli exportguild -t "mfa.Ifrn" -g 21814 --include-vc false
+```
+
+### Export all channels
+
+To export all accessible channels, use the `exportall` command:
+
+```console
+./DiscordChatExporter.Cli exportall -t "mfa.Ifrn"
+```
+
+#### Excluding DMs
+
+To exclude DMs, add the `--include-dm false` option.
+
+```console
+./DiscordChatExporter.Cli exportall -t "mfa.Ifrn" --include-dm false
+```
+
+### List channels in a server
+
+To list the channels available in a specific server, use the `channels` command and provide the server ID through the `-g|--guild` option:
+
+```console
+./DiscordChatExporter.Cli channels -t "mfa.Ifrn" -g 21814
+```
+
+### List direct message channels
+
+To list all DM channels accessible to the current account, use the `dm` command:
+
+```console
+./DiscordChatExporter.Cli dm -t "mfa.Ifrn"
+```
+
+### List servers
+
+To list all servers accessible by the current account, use the `guilds` command:
+
+```console
+./DiscordChatExporter.Cli guilds -t "mfa.Ifrn" > C:\path\to\output.txt
+```

+
+> Video by [NoIntro Tutorials](https://youtube.com/channel/UCFezKSxdNKJe77-hYiuXu3Q).
+
+## Guide
+
+### Step 1
+
+After extracting the `.zip`, run `DiscordChatExporter.exe` **(Windows)**, or `DiscordChatExporter` **(Linux)**.
+
+If you're using **macOS**, you'll need to manually grant permission for the app to run.  
+If you skip these steps, the "DiscordChatExporter is damaged and can’t be opened" error will be shown.
+
+1. Open Terminal.app. You can search for it in Spotlight (press <kbd>⌘</kbd> + <kbd>Space</kbd> and type "Terminal").
+2. Paste the following into the terminal window:
+   ```bash
+   xattr -rd com.apple.quarantine
+   ```
+3. Hit <kbd>Space</kbd> once to add a space after the command
+4. Drag and drop DiscordChatExporter.app into the terminal window
+5. Press <kbd>Return</kbd> to run the command
+6. Open DiscordChatExporter.app normally
+
+> Apple requires apps to be notarized and signed in order to run on macOS without warnings, which in turn requires an Apple Developer membership ($99/year). This open-source project is distributed for free and without commercial intent.
+
+### Step 2
+
+Please refer to the on-screen instructions to get your token, then paste your token in the upper text box and hit ENTER or click the arrow (→).
+
+> [!WARNING]
+> **Never share your token!**
+> A token gives full access to an account, treat it like a password.
+
+<img src="https://i.imgur.com/SuLQ5tZ.png" height="400"/>
+
+### Step 3
+
+DCE will display your Direct Messages and a sidebar with your server list. Select the channel you would like to export, then click the ![Screenshot](https://i.imgur.com/dnTOlDa.png) button to continue.
+
+> **Note**:
+> You can export multiple channels at once by holding `CTRL` or `SHIFT` while selecting.
+> You can also double-click a channel to export it without clicking the ![Screenshot](https://i.imgur.com/dnTOlDa.png) button.
+
+<img src="https://i.imgur.com/JHMFRh2.png" height="400"/>
+
+### Step 4
+
+In this screen you can customize the following:
+
+- **Output path** - The folder where the exported chat(s) will be saved.
+
+- **Export format** - HTML (Dark), HTML (Light), TXT, CSV and JSON
+
+- **Date range (after/before)** (Optional) - If set, only messages sent in the provided date range will be exported. Only one value (either after or before) is required if you want to use this option.
+  > **Note**:
+  > Please note that the time defaults to **12:00 AM** (midnight/00:00). This means that if you choose to export between Sep 17th and Sep 18th, messages from Sep 18th won't be exported.
+
+- **Partition limit** (Optional) - Split output into partitions, each limited to this number of messages (e.g. 100) or file size (e.g. 10mb). For example, a channel with 36 messages set to be partitioned every 10 messages will output 4 files.
+
+- **Message Filter** (Optional) - Special notation for filtering the messages that get included in the export. See [Message filters](Message-filters.md) for more info.
+
+- **Format markdown** (Optional) - Disable markdown processing when exporting. You can use this to produce JSON or plain text exports without unwrapping mentions, custom emoji, and certain other special tokens.
+
+- **Download assets** (Optional) - If this option is set, the export will include additional files such as user avatars, attached files, images, etc. Only files that are referenced by the export are downloaded, which means that, for example, user avatars will not be downloaded when using the plain text (TXT) export format. A folder containing the assets will be created along with the exported chat. They must be kept together.
+
+- **Reuse assets** (Optional) - If this option is set, the export will reuse already downloaded assets to skip redundant requests. This option is only available when **Download assets** is enabled.
+
+- **Assets directory path** (Optional) - If this option is set, the export will use the specified directory to store assets from all exported channels in the same place.
+
+> **Note**:
+> You need to scroll down to see all available options.
+
+## Settings
+
+- **Auto-update** - Perform automatic updates on every launch.
+Default: Enabled
+
+  > **Note**:
+  > Keep this option enabled to receive the latest features and bug fixes!
+
+- **Dark mode** - Use darker colors in the UI (User Interface).
+Default: Disabled
+
+- **Persist token** - Persist last used token between sessions.
+Default: Enabled
+
+- **Show threads** - Controls whether threads are shown in the channel list.
+Default: none
+
+- **Locale** - Customize how dates are formatted in the exported files.
+
+- **Date format** - Customize how dates are formatted in the exported files in the settings menu ().
+
+- **Parallel limit** - The number of channels that will be exported at the same time.
+Default: 1
+
+  > **Note**:
+  > Try to keep this number low so that your account doesn't get flagged.
+
+- **Normalize to UTC** - Convert all dates to UTC before exporting.

-### v2.34.1 (01-Jun-2022)
-
-- Improved retry policy to handle more transient errors. This should result in fewer errors exporting a channel due to timeout.
-- Added `has:pin` message filter. You can use it to limit exported messages to those that have been pinned. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
-- Fixed an issue which caused the export to fail when processing stickers that have no name.
-
-### v2.34 (10-Apr-2022)
-
-- [HTML] Reworked layout to be more consistent with Discord.
-- [HTML] Changed user profile picture dimensions from `128x128` to `512x512`. (Thanks [@Chris Helder](https://github.com/TheDude53))
-- [HTML] Improved image scaling for Chromium-based browsers. This should result in higher quality images across the entire export.
-- [HTML] Hovering over messages will now show short timestamps on the left, indicating the time that the individual messages of the group were sent.
-- [HTML] Using "download media" option will now also download scripts, styles, fonts, and other similar resources used by the export.
-- [HTML] Image attachments will now use the provided description as alt text.
-- [HTML] Fixed a few layout inconsistencies related to embeds.
-- [GUI] Added a few clickable links to the usage guide to make the process of locating tokens easier.
-
-### v2.33.2 (07-Mar-2022)
-
-- Actually fixed it this time.
-
-### v2.33.1 (07-Mar-2022)
-
-- Fixed an issue where the application silently failed to run if the system didn't have .NET Runtime 6.0.2 installed. If you continue seeing this issue, please uninstall all existing .NET runtimes from your computer and then try running the application again.
-
-### v2.33 (06-Mar-2022)
-
-- Added messages informing about war in Ukraine and available ways to help.
-- Added support for rendering stickers in HTML and JSON. Lottie-based stickers currently cannot be displayed in HTML exports (see [#803](https://github.com/Tyrrrz/DiscordChatExporter/issues/803)).
-- Added a new `reaction:` message filter which can be used to check if someone reacted to a message with a specific emoji. You can either pass the emoji name (e.g. `reaction:LUL`) or its ID (e.g. `reaction:41771983429993937`).
-- [GUI] Added auto-detection for dark mode. If your system is configured to prefer dark mode in applications, DiscordChatExporter will use it by default instead of light mode.
-- Fixed an issue which caused the export process to crash when downloading media files with extremely long file extensions. (Thanks [@Tomlacko](https://github.com/Tomlacko))
-- Fixed an issue which caused the export process to crash on invalid mentions.
-- [GUI] Fixed an issue where the time pickers used to specify export ranges always displayed time in 12-hour format, instead of respecting the system locale.
-
-### v2.32 (27-Jan-2022)
-
-- Token kind (user or bot) is now detected automatically. Removed the button to switch token kind in GUI. Option `-b|--bot` in CLI is now deprecated and does nothing.
-- Updated user token extraction guide to reflect the fact that devtools are no longer accessible in the desktop version of Discord client. The recommended workaround is to open Discord in browser. (Thanks [@Dhananjay-JSR](https://github.com/Dhananjay-JSR))
-- Fixed an issue which caused an error when parsing invalid date timestamps. Such timestamps are now rendered as "Invalid date", similarly to how the Discord client does it.
-- Fixed an issue which caused an error when parsing certain embed fields.
-- Fixed an issue which caused an error when parsing a mention to a user that has no username.
-- [GUI] Minor visual fixes.
-
-### v2.31.1 (15-Dec-2021)
-
-- Fixed an issue which caused an error when parsing certain custom emoji reactions.
-- [GUI] Improved user interface.
-
-### v2.31 (06-Dec-2021)
-
-- Changed target runtime of the application (both GUI and CLI) from .NET 3.1 to .NET 6. Those using the GUI version will not need to take any action as the application should install the necessary prerequisites automatically. Those using the CLI version will need to download and install .NET 6 runtime manually [from here](https://dotnet.microsoft.com/download/dotnet/6.0) (look for ".NET Runtime 6.0.x" section on the right and choose the distribution appropriate for your system).
-- [HTML] Updated layout design to match Discord more closely. (Thanks [@Artem](https://github.com/Scarg))
-- [HTML] Fixed an issue where markdown inside channel topic was not rendered correctly. (Thanks [@Emily](https://github.com/emillly-b))
-- [HTML] Fixed an issue where the layout was broken for messages containing text in right-to-left languages. (Thanks [@Emily](https://github.com/emillly-b))
-- Fixed an issue where text filters weren't matching content inside of embeds.
-- [GUI] Fixed a multitude of issues related to the bootstrapper.
-
-### v2.30.1 (28-Aug-2021)
-
-- [HTML] Changed user avatars to render using higher resolution images. (Thanks [@Chris Helder](https://github.com/TheDude53))
-- Fixed an issue where `has:file` message filter was not recognized. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
-- Fixed an issue where a unix timestamp marker with an invalid offset crashed the export process.
-
-### v2.30 (08-Aug-2021)
-
-- [HTML] Added special casing for Spotify track embeds to render them directly using an embedded player.
-- [HTML] Added special casing for plain image embeds to render them like image attachments.
-- [HTML] Added tooltip text for unix timestamp markers which shows the full date represented by the timestamp, regardless of configured date format. 
-- [HTML] Updated the fallback text shown when the referenced message could not be loaded to make it more explicit.
-- [HTML] Updated styling of quoted text in markdown to more closely resemble how it looks in Discord.
-- [HTML] Fixed an issue where some file formats were not correctly recognized as image or video attachments, which affected how they were rendered.
-- [HTML] Fixed an issue where formatting inside named links (e.g. `[**Bold link**](https://example.com)`) was not being parsed.
-- [HTML] Fixed an issue where inline embed fields were missing horizontal spacing between columns.
-- [HTML] Fixed other minor styling issues.
-
-### v2.29 (19-Jul-2021)
-
-- Added support for message filtering, which is accessible as an additional export parameter in the GUI and as the `--filter` option in the CLI. Message filters use a special syntax similar to Discord's search query syntax to allow specifying which messages should be included in the export. For example, you can limit the export to only include messages that contain image attachments (`has:image`) or messages from a certain user (`from:Tyrrrz`) or messages containing certain words (`hello world`), etc. You can also combine filters together (`hi mentions:Tyrrrz`, `from:Tyrrrz | from:96-LB`, `(mentions:Tyrrrz | from:Tyrrrz) has:image`) or negate them (`-has:link`). More thorough documentation coming soon. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
-- Added support for rendering mentions of voice channels, in addition to text channels.
-- Added support for rendering unix timestamp markers. Currently, style markers are ignored and timestamps are always rendered with the format configured in settings (or provided via `--date-format` option).
-- Updated in-app instructions for obtaining a user token. (Thanks [@Yudi](https://github.com/Yudi) and [@virtuallyvlad](https://github.com/virtuallyvlad))
-- [HTML] Improved visual appearance of the reference symbol (Г-shaped line in replies) to make it more closely resemble Discord's styling.
-- [HTML] Added more specific fallback text used when rendering referenced messages that contain no text content but have attachments or embeds.
-- [HTML] Fixed an issue where a broken embed author icon occupied visual space, ruining the embed layout. (Thanks [@Cliff J.](https://github.com/CliffJameston))
-- [GUI] Improved handling for fatal errors that may occur when attempting to export a channel. These errors are now displayed in a popup, allowing the user to try again instead of having the application crash completely.
-- [CLI] Fixed an issue where an attempt to export a channel resulted in `NotSupportedException` when the default encoding was set to `UTF8`.
-- [CLI] Fixed an issue where providing an incorrectly formatted partition limit via `-p|--partition` option resulted in a non-descriptive and unhelpful error.
-- Improved "Requested resource does not exist" error message by including the ID of the requested resource.
-
-### v2.28 (19-Jun-2021)
-
-- [HTML] Added special casing for YouTube video embeds to render them directly using an embedded player. (Thanks [@quentinmay](https://github.com/quentinmay))
-- [HTML] Added support for rendering standard emoji by code. Such emoji may sometimes be found in messages sent by bots or through webhooks. (Thanks [@CanePlayz](https://github.com/CanePlayz) and [@Lucas LaBuff](https://github.com/96-LB))
-- [HTML] Changed tooltips on standard emoji to show emoji code instead of their raw string representations. (Thanks [@CanePlayz](https://github.com/CanePlayz) and [@Lucas LaBuff](https://github.com/96-LB))
-- [HTML] Added tooltips on individual messages to show when those messages were sent. 
-- [HTML] Updated colors and minor styling elements to match Discord's new style direction after rebranding.
-- [HTML] Updated Twemoji URLs to use SVG image variants for better rendering quality.
-- [HTML] Changed user avatar URLs to include predetermined size query parameter for better rendering quality.
-- Changed embed rendering logic to prefer Discord-proxied URLs for external content, in order to avoid unnecessary HTTP requests to third parties.
-- Fixed an issue where exporting with media sometimes resulted in a crash due to lack of permissions to change file attributes. These errors are now ignored, which means that the creation, write, and access dates of downloaded files may sometimes not match the dates provided by Discord's CDN.
-- [HTML] Fixed styling issues when rendering embed footers.
-- [HTML] Fixed an issue where links didn't render properly inside referenced messages.
-- [HTML] Fixed an issue where standalone emoji were incorrectly enlarged inside referenced messages.
-- [HTML] Fixed an issue where clicking on a referenced message revealed spoilers inside of it.
-- [GUI] Fixed an issue where the list of missing components, reported by the prerequisite check at application startup, included Windows updates that were not applicable to the user's system due to the fact that other superseding updates have already been installed. This issue only affected users running DiscordChatExporter on Windows 7.
-- [GUI] Fixed a few other minor issues related to the prerequisite installation window.
-
-### v2.27.1 (08-Jun-2021)
-
-- [GUI] Application will now detect if the required .NET Runtime or any of its prerequisites are missing and prompt the user to download and install them automatically. **Experimental feature, please test it out and report any issues you may find!**
-- [CLI] Fixed an issue where the application crashed when exporting a channel that had square brackets as part of its name or category name. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
-
-### v2.27 (24-Apr-2021)
-
-- Added partitioning by file size. You can now use values such as `10mb` to indicate a size-based cut off point, in addition to values like `10` to indicate a number of messages. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
-- [CLI] Improved formatting and progress reporting.
-- [CLI] Changed `export` command so that it can accept multiple channel IDs passed to `-c|--channel` option. This makes it possible to export multiple channels at once while benefiting from parallelization.
-- [JSON] Added `color` field to message author. This is a hex string that represents user's color, inherited from their roles. (Thanks [@rtm516](https://github.com/rtm516))
-- [JSON] Added `categoryId` field to the root. This represents the ID of the category channel that the currently exported channel belongs to. (Thanks [@rtm516](https://github.com/rtm516))
-- [JSON] Fixed an issue where user discriminator was written without leading zeroes. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
-- [JSON] Fixed an issue where the application sometimes crashed with an error saying `']' invalid without a matching open`, which was just a validation message that masked the actual error behind the failure. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
-- Fixed an issue where progress was not reported correctly if the channel didn't have any messages in the specified time range.
-
-### v2.26.1 (06-Feb-2021)
-
-- [CLI] Added support for file name templates, which allow you to dynamically generate output file names based on channel and guild metadata. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
-- Fixed an issue where the application sometimes crashed with `Invalid snowflake` message when exporting chat logs that contained invalid or outdated mentions. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
-
-### v2.26 (29-Dec-2020)
-
-- [HTML] Added support for replies. (Thanks [@Sanqui](https://github.com/Sanqui))
-- [HTML] Improved styling of non-media attachments (regular files, i.e. not video, audio, or image). (Thanks [@Lucas LaBuff](https://github.com/96-LB))
-- [HTML] Improved initial export performance.
-- [JSON] Relaxed escaping rules for unicode characters. (Thanks [@Sanqui](https://github.com/Sanqui))
-- [JSON] Added support for replies. (Thanks [@Sanqui](https://github.com/Sanqui))
-- [CLI] Added channel names to errors shown on failures when exporting multiple channels. (Thanks [@Sanqui](https://github.com/Sanqui))
-- [CLI] Added support for passing message IDs (snowflakes) to `--after` and `--before` options. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
-- Files downloaded by the "download referenced media" option now have their dates set according to the `Last-Modified` header provided by Discord CDN. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
-- Fixed an issue where the application sometimes crashed with `NullReferenceException` when retrying a failed HTTP request.
-- Migrated to Discord API v8.
-
-### v2.25 (23-Nov-2020)
-
-- [JSON] Added `mentions` property to the output. This contains users referenced inside the message text, but doesn't include mentions in embeds. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
-- [HTML] Added better previews for attached video and audio. They are now rendered using a browser native player element. The actual file path can still be retrieved by right clicking and selecting "Copy file path". (Thanks [@sas41](https://github.com/sas41))
-- [CLI] Fixed an issue where using `--media` option without providing a rooted path via `--output` option triggered an error.
-- [CLI] Fixed an issue where using `--reuse-media` option without also providing `--media` option was accepted, but didn't actually do anything. Now this produces an error instead. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
-
-### v2.24 (24-Oct-2020)
-
-- [CLI] Updated to [CliFx v1.5](https://github.com/Tyrrrz/CliFx), which brings some UX improvements.
-- [GUI] Added dark mode, which can be enabled in settings. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
-- [GUI] Improved the UX in a few minor places.
-- [JSON] Added `embed.color` property to the output. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
-- Added additional date formats: `unix` to write dates as a unix timestamp and `unixms` for the milliseconds version. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
-- Added retry policy for downloading media content. This is mostly a workaround for transient failures that sometimes may occur when downloading assets referenced from embeds. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
-- Added an option to reuse already downloaded media to avoid redundant network requests. It can be enabled in settings in GUI, or by passing `--reuse-media` in CLI. To facilitate this feature, the file name strategy has been changed as well -- now instead of relying on the original file name and adding `(n)` to the end in case of duplicates, a URL hash is injected in every file name. This also means that when the "reuse media" option is disabled, existing files inside the media directory may be overwritten. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
-
-### v2.23 (14-Sep-2020)
-
-- [CLI] Added a command to export all channels across all servers. Use `exportall` to do it. (Thanks [@wyattscarpenter](https://github.com/wyattscarpenter))
-- [HTML] Fixed an issue where Whitney fonts were not being loaded properly, causing the browser to fall back to Helvetica.
-- Fixed an issue where self-contained export crashed occasionally. This usually happened when the server hosting the file did not serve the stream properly. Such files are now ignored after the first failed attempt.
-
-### v2.22 (12-Aug-2020)
-
-- [GUI] Improved the channel list by adding collapsible category groups. (Thanks [@CarJem Generations](https://github.com/CarJem))
-- [GUI] Improved exporting options by adding a set of controls that can be used to limit the date range of the export down to minutes. Previously it was only possible to configure the date range without the time component. (Thanks [@CarJem Generations](https://github.com/CarJem))
-- [HTML] Fixed an issue where the export didn't reflect changes in nicknames between messages sent by bots. This affected chat logs that contained interactions with the Tupperbox bot. (Thanks [@CarJem Generations](https://github.com/CarJem))
-- [CLI] Fixed an issue where the application crashed if there were two environment variables defined that had the same name but in different case.
-
-### v2.21.2 (30-Jul-2020)
-
-- [GUI] When copy-pasting token, any surrounding spaces are now discarded, in addition to double quotes.
-- [HTML] Changed underlying templating engine to provide higher performance and better error messages. New templating engine adds a small cold start, but any export after the first should be faster.
-- Changed naming schema for downloaded media so that it follows `<original filename> (nn)` format rather than `<original filename>-salt`.
-- [HTML] Fixed an issue where downloaded media was sometimes inaccessible due to reserved characters appearing in the URL.
-- Fixed an issue where the application crashed when trying to download media with a file name that exceeds system's maximum allowed length.
-- Fixed an issue where the application crashed when trying to download media with illegal characters in the file name.
-
-### v2.21.1 (19-Jul-2020)
-
-- Fixed an issue where the export crashed if an embedded image has been deleted. Such media files are now ignored.
-- Changed the naming convention for downloaded media files so that the original file names are used when possible.
-
-### v2.21 (18-Jul-2020)
-
-- Added a new option that enables self-contained exports for all output formats. You can turn it on in the export setup dialog in GUI or using the `--media` option in CLI. When using this, the application will additionally download any media content directly referenced from the exported file instead of linking back to Discord CDN. The files which are downloaded include: guild icons, user avatars, attachments, embedded images, reaction emoji. Note that only files which are actually referenced by the export are downloaded, which means that, for example, user avatars will not be downloaded when using plain text export format. This option is not meant to enable complete offline viewing for HTML exports, but rather to make it easier to archive media content that may eventually get deleted from Discord servers. Also keep in mind that this option may make the export drastically slower and the total file size larger.
-- Changed "discordapp.com" to "discord.com" where applicable as Discord is migrating to a new domain. CDN will remain on "cdn.discordapp.com" for the foreseeable future.
-
-Note that all existing and current HTML exports will likely not render accurately because Discord enabled CORS for their font resources, which prevents them from loading locally. Please refer to [issue #322](https://github.com/Tyrrrz/DiscordChatExporter/issues/322) for discussion on this topic. 
-
-### v2.20 (27-Apr-2020)
-
-- [CLI] Added environment variables as fallback for `--token` and `--bot` options. They are `DISCORD_TOKEN` and `DISCORD_TOKEN_BOT` respectively.
-- [GUI] Fixed a crash that occurred if the application was closed in the middle of an auto-update.
-- [GUI] Added a link to project's wiki in the usage guide.
-- [HTML] Added full spoiler support for text and images. To spoil the hidden content you now need to click on it, similarly to how it works in Discord. (Thanks [@FM-96](https://github.com/FM-96))
-- [HTML] Updated grammar for consecutive single-line quotes. Previously they appeared separately, now they're grouped together as if it was one multi-line quote instead.
-- [HTML] Fixed an issue where messages sent by the same bot but with different usernames were grouped together when they shouldn't be.
-- [HTML] Updated grammar for single-line code blocks to accept double backticks as synonymous with single backticks. This change makes code blocks appear the same, whether they were inserted manually or using Discord's buggy markdown preview mode.
-- [HTML] Fixed styling inconsistencies and other minor issues.
-- [TXT/JSON] Fixed an issue where markdown was not parsed correctly in embed fields.
-- [HTML] Changed markdown formatting in embeds so it follows the same set of rules as in Discord.
-- Added channel category to the default file name used when exporting chat logs.
-- [HTML/TXT/JSON] Added channel category to exported metadata.
-- [CLI] Updated commands to also show channel category as well as channel name wherever relevant.
-- Starting with this release, Docker images will have new tags: `stable` for latest stable release and `2.20` for a specific version.
-
-### v2.19 (26-Mar-2020)
-
-- Added parallel exporting. This option allows you to export multiple channels faster by doing it in parallel. You can configure the parallel limit in settings (GUI) or with the `--parallel` option (CLI). Default value is `1`, which means there is no parallelization. Warning: be careful when using this option, as this will result in higher volume of concurrent HTTP requests sent to Discord, which might get you flagged. Use at your own risk.
-- [HTML] Added support for user colors. User names are now appropriately colored according to the assigned guild roles.
-- [HTML] Added support for nicknames. User names are replaced with nicknames where it's applicable. It's still possible to see the full user name by hovering your mouse over the nickname.
-- [HTML] Improved styling for mentions to bring it more in line with how it looks in Discord.
-
-### v2.18 (04-Feb-2020)
-
-- Added JSON export format. It's a structured data format which is easy to parse. If you're using DiscordChatExporter to export chat logs for further ingestion by another tool, this is most likely the format you will want to use.
-- [GUI] You can now quickly jump to a specific channel in a list. For example, if you want to jump to a channel named "General", you can simply press the 'g' key in the channel list view. You can also press 'g', 'e' and 'n' in quick succession which will jump to the next channel that starts with "gen". This mechanic is consistent with other Windows applications.
-- [CLI] Improved help text screen.
-
-### v2.17 (12-Jan-2020)
-
-- Fixed an issue where an empty file was produced when exporting a channel with no messages (for specified period). With the new behavior, no file will be created and instead a message will be shown to the user informing of the failure.
-- [HTML/TXT] Added message count to the bottom of the file. This number shows how many messages were exported as part of the current file. Prior to 2.16 this number was present along with the rest of the metadata at the top, then removed due to changes in the exporter, and now brought back at the end of the file instead.
-- [HTML] Fixed an issue where some emoji were not properly rendered.
-- [GUI] Added a setting that lets you configure whether to remember the last used token. Previously it was the default behavior, but now you can disable it if you don't want the token persisted on your system.
-
-### v2.16 (08-Dec-2019)
-
-- Migrated from .NET Framework to .NET Core. To run this and future versions of DiscordChatExporter you will need [.NET Core runtime for desktop apps](https://dotnet.microsoft.com/download/dotnet-core/3.1/runtime) (for GUI/CLI version on Windows) or [.NET Core base runtime](https://dotnet.microsoft.com/download/dotnet-core/3.1) (for CLI version on Windows, Linux or macOS).
-- Reworked the exporter engine to render output using streaming data source. This means that only a very small portion of messages are cached in memory when exporting. In other words, you are only limited by storage space and not how much RAM you have, so you can now export terabytes of chat logs without hitting out of memory exceptions. I still recommend using partitions if you're exporting very large chat logs (250k+ messages) to HTML, unless you want your computer to catch fire when you try to open the export in browser.
-- Changed how partitioned files are named, due to the fact that total number of partitions is no longer known ahead of time.
-- Added a warning about automating user accounts to the usage guide in both GUI and CLI versions.
-- Added support for announcement (news) channels. You will now be able to see them in the list and export them.
-- Fixed various issues that resulted in exceptions during export process.
-- [HTML/TXT] Removed message count from the metadata. Due to the fact that the messages are exported as they are streamed, total number of messages is not known ahead of time.
-- [HTML] Changed default color of the embed color pill to match the theme.
-- [HTML] Changed emoji parser to be less greedy. As a result it should match fewer character sequences that look like emoji but really aren't, but on the other hand it might miss some actual emoji. This means that some standard emoji (i.e. not custom server emoji) may not look like in Discord. This is a compromise I'm willing to take because detecting emoji in text is really hard to get right and not worth it at all.
-- [HTML] Some other minor styling adjustments.
-- [CSV] Replaced semicolons (;) with (,) as separators.
-
-Please note that CSV export is most likely not going to receive future updates and will remain only as an option for those who wish to use it for text analysis. In other words, it won't contain any of the rich media features like embeds. If you're currently using CSV as a structured output to feed into your program, JSON output will replace that in the future.
-
-### v2.15 (15-Sep-2019)
-
-- Improved markdown parser and made it even faster for non-HTML formats.
-- [HTML] Added support for block quotes.
-- [HTML] Links pointing to a Discord message will now navigate to the linked message inside exported chat log if it's there.
-- [HTML] Updated light theme to match how it looks in Discord after recent changes.
-- [HTML] Added indication for when a message is pinned. Pinned messages now have a tinted background.
-- [HTML] Fixed an issue where multiline code blocks sometimes had incorrect formatting applied to them.
-- [TXT] Added indication for when a message is pinned. Pinned messages now have `(pinned)` next to timestamp and author.
-- [CSV] Added message author's user ID to output.
-- [GUI] Streamlined auto-update process a bit.
-- [GUI] Added some tooltips.
-
-### v2.14 (15-Jun-2019)

-
-### v2.13.1 (06-Jun-2019)
-
-- Fixed an issue where the app sometimes crashed when exporting due to `System.InvalidCastException`.
-- [HTML] Added `data-user-id` attribute to `span.chatlog__author-name`. The value of this attribute is author's Discord user ID.
-
-### v2.13 (15-May-2019)
-
-- Updated usage instructions.
-- [HTML] Added BOT tags to messages posted by bots.
-- [GUI] UI will now be disabled when exporting.

-
-### v2.12.1 (12-Apr-2019)
-
-- [GUI] Fixed an issue where the app crashed when trying to export multiple channels.
-- [HTML] Fixed an issue where some of the emoji were rendered via Twemoji while Discord renders them as plain text.
