## Install
1. Get [Transmission](https://transmissionbt.com) and setup its [web interface](https://helpdeskgeek.com/how-to/using-the-transmission-web-interface/)
2. Install python 3, [transmissionrpc](https://pypi.org/project/transmissionrpc/), and [discord.py](https://pypi.org/project/discord.py/)
3. Clone this repository using `git clone https://github.com/twilsonco/TransmissionBot`
## Configure
1. Setup your new bot on Discord:
1. Sign up for a Discord [developer account](https://discord.com/developers/docs)
2. Go to the [developer portal](https://discordapp.com/developers/applications), click *New Application*, pick a name and click *Create*
* *Note the `CLIENT ID`*
3. Click on *Bot* under *SETTINGS* and then click *Add Bot*
4. Fill out information for the bot and **uncheck the `PUBLIC BOT` toggle**
* *Note the bot `TOKEN`*
2. Invite the bot to your server
1. Go to `https://discordapp.com/api/oauth2/authorize?client_id=<client_id>&scope=bot&permissions=<permissions>`
* replace `<client_id>` with the `CLIENT ID` from above
* replace `<permissions>` with the minimum permissions `93248`(*for read/send/manage messages, embed links, read message history, and add rections*) or administrator permissions `9` to keep things simple
2. Invite the bot to your server
2. Configure `bot.py`
1. Set values in the `CONFIG` variable, which are described inline
* After first run, a `config.json` file will be created in the same directory as `bot.py`. This file should then be used to make any configuration changes, and the definition of `CONFIG` in `bot.py` should be commented out or removed.
2. Configure logging
* Pick a location for the logfile on line 112
* Optionally disable logging by setting the log level to `logger.CRITICAL` which isn't used anywhere
3. Run with `python3 /path/to/TransmissionBot/bot.py` and enjoy!
## Detailed features
### <a name="channelDM">Interact via text channels or DMs</a>
* Use commands with `t/` prefix in text channel or via DM
* Via DM only, use full command name without prefix (*e.g.* `summary`)
### <a name="add">Add transfers</a>
* Simply drag a `.torrent` file into the channel on discord and it will be added and started
* Alternatively, enter a transfer magnet link or an address to a `.torrent` file using `t/add MAGNET_OR_URL`
### <a name="modify">Modify existing transfers</a>
* `t/modify` to pause, resume, verify, remove, or remove and delete one or more transfers
* Specify transfers using sequence of ids (*e.g.* 1,3,5-8), searching transfer names with regular expressions, or filtering by transfer properties (*e.g.* downloading, finished, etc.)
* Limit number of matches using `-N` option
* Option to protext transfers using private trackers from removal
* `t/help modify` for more info
### <a name="status">Check transfer status</a>
#### List one or more transfers with pertinent information
* `t/list`
* Specify transfers using sequence of ids<sup>[1](#idseq)</sup>, searching transfer names with regular expressions, or filtering by transfer properties (e.g. downloading, finished, etc.)
* Click 🔄 reaction to update output in realtime (in-channel only, not through DM)
* `t/help list` for more info
#### Print transfer summary
* `t/summary`
* Includes overall transfer rates, amount of data transferred (based on current set of transfers), transfer counts for different states (*e.g.* downloading, finished, etc.), and list of highest seed-ratio transfers (configurable)
* Click 🔄 reaction to update output in realtime (in-channel only, not through DM)
* Use other reactions to print filtered lists of transfers
* Print symbol `t/legend`
### <a name="notifications">Notification system for transfer state changes</a>
* Print notifications regarding transfer state changes in a text channel and through DMs
* Users are notified through DM about transfers they added
* Can opt in to DM notifications for other transfers by reacting with 🔔 to `t/list` message or in-channel notifications
* Opt out of DM notifications
* Opt out of individual DM notifications by reacting with 🔕 to `t/list` message or either in-channel or DM notifications
* Users opt out of all DM notifications using `t/notifications` through DM
* Owners can disable in-channel notifications using `t/notifications` in a listened channel
* Customize what state changes are included in the configuration
### <a name="pretty">Pretty output and highly configurable</a>
* Output automatically formatted for display on desktop or mobile discord clients (in-channel only, not through DM)
* Use of Embeds and unicode symbols where appropriate.
* Remove reactions from messages when no longer necessary for prettier scroll-back (in-channel only, not through DM)

* Toggle dry-run to control whether transfer modifications are actually carried out
### <a name="help">`t/help` for usage information</a>
* Print help for some commands using `t/help COMMAND_NAME` (*e.g.* `t/help list`)
### <a name="setup">Easy setup</a>
0. Setup bot on Discord developer portal
1. Clone repository `git clone https://github.com/twilsonco/TransmissionBot`
2. Configure `CONFIG` in `bot.py` to your liking
3. Run bot `python3 /path/to/bot.py`
* Bot will create `config.json`, after which you can remove or comment the definition of `CONFIG` in `bot.py` to make future updates easier
## To-do (~~implemented~~)
* Command to print detailed information for transfer(s)
* Complete connection information
* Lists of transfer files, peers, trackers
* ~~Add ability to verify transfer data~~
* When searching by name, update regex to include potential accented characters, eg `pokemon` would also match `pokémon`
* ~~Specify number of transfers to show when using `list` or `modify`~~
* Combine the `list` and `modify` commands in the code, with a simple parameter to specify whether or not modification is allowed
* Currently, searching by name is done with case-insensitive regex. Update to that if a user includes upper case characters, case-sensitive search is performed
* ~~Add recurring list option. Ie every five seconds replace `list` output with fresh output. This would be done by reacting to a "repeat" emoji to initiate repetition of the current search~~ (also did this for `summary`)
* ~~Add additional filtering options: stalled, error, non-zero up/down rate.
* Add shorthand for filtering options (downloading/seeding/stalled/paused become d/s/i/p etc., that's i for "idle" since s is for seeding)
* Add a `top` command that'sessentially a combination of the up/down rate filter and the repeating output features
* Ability to refine `list` output with filter or sort using reactions; ie click a filter or sort reaction which triggers another message with additional reactions to click to apply the extra filters or sort
* Ability to specify which files to include in download (we'll see about that; sounds clunky but maybe using file ID specifiers *e.g.* `1,3-5,8`)
* ~~Notifications for when a transfer finishes/stalls/errors
* ~~via DM to the user that added the transfer
* ~~or by posting to the channel from which a transfer was added
* ~~Let other users opt to receive notifications for transfers they *didn't* add
* Post-download file management (*never going to happen...*)
* Compress files (encrypted) and make available for direct download from server via download link posted to channel or DM'd to user
* ~~Use JSON config file so that updating is non-destructive
* Add `set` command so owners can edit configuration through Discord
* ~~Add a toggle for minimalised output for better display on mobile devices. Toggle using `t/compact` as standalone command or by clicking a 📱 reaction. Store as global variable so all commands output can be affected.~~
