Bot messages in threads have subtype set to bot_message (just like bot
messages in channels), so we can't use subtype to check if a message is
a thread message or a channel message.

Fixes #749

Table of Contents

Features

  • Threads support
  • Slack status support
  • Slash commands (including custom ones)
  • Upload to slack capabilities
  • Emoji reactions
  • Edited messages work just like the official clients, where the original message changes and has (edited) appended.
  • Unfurled urls dont generate a new message, but replace the original with more info as it is received.
  • Regex message editing (s/oldtext/newtext/)
  • Smarter redraw of dynamic buffer info (much lower CPU %)
  • Multiple Teams supported. Just add multiple api tokens separated by commas
  • Replays history automatically during startup. (and sets read marker to the correct position in history)
  • Open channels synchronized with Slack. When you open/close a channel on another client it is reflected in wee-slack
  • Colorized nicks in chat
  • Supports bidirectional slack read notifications for all channels. (never reread the same messages on the web client or other devices).
  • Typing notification, so you can see when others are typing, and they can see when you type. Appears globally for direct messages
  • Away/back status handling
  • Expands/shows metadata for things like tweets/links
  • Super fun debug mode. See what the websocket is saying

Dependencies

Setup

1. Install dependencies

Arch Linux: pacman -S python-websocket-client

Debian/Ubuntu: apt install weechat-python python-websocket. If using weechat 2.6 or newer, run apt install weechat-python python3-websocket instead.

Fedora: dnf install python3-websocket-client

FreeBSD: pkg install py36-websocket-client

OpenBSD: pkg_add weechat-python py3-websocket-client

Other: pip3 install websocket-client

Note for macOS: If you installed weechat with Homebrew, you will have to locate the python runtime environment used. If --with-python@2 was used, you should use: sudo /usr/local/opt/python@2/bin/pip2 install websocket_client

2. Download wee_slack.py to ~/.weechat/python

If you don't want wee_slack to start automatically when weechat starts, you can skip the last command.

mkdir -p ~/.weechat/python/autoload
cd ~/.weechat/python
curl -O https://raw.githubusercontent.com/wee-slack/wee-slack/master/wee_slack.py
ln -s ../wee_slack.py autoload

3. Start WeeChat

weechat

NOTE: If weechat is already running, the script can be loaded using /python load wee_slack.py.

4. Add your Slack API token(s)

There are two types of tokens that can be used, OAuth tokens and session tokens. The official way to get a token is to use OAuth. However, this has several drawbacks, so an alternative way is to pull a session token out of the web client.

Drawbacks of OAuth tokens:

  • If the team is restricting app installations, wee-slack has to be approved by an admin.
  • For free teams, wee-slack will use one of the ten app slots.
  • The subscribe and unsubscribe commands won't work.
  • Threads, shared channels and channels that has been converted from public to private can only be marked as read locally, it won't sync to Slack. This means they will be unread again after reloading the script.

Drawbacks of session tokens:

  • These tokens can't be revoked, so be careful not to loose them.
  • They are not officially supported, and may stop working at any time.

Get a token with OAuth

Log in to Slack:

/slack register

This command prints a link you should open in your browser to authorize WeeChat with Slack. If the page shows a different team than the one you want to add, you can change the team in the top right corner of the page.

Once you've accomplished this, the page will show a command which you should run in WeeChat. The command is of the form:

/slack register <code>

Your Slack team is now added, and you can complete the setup by reloading the wee-slack script.

/python reload slack

Note that by default GitHub Pages will see a temporary code used to create your token (but not the token itself). If you're worried about this, you can use the -nothirdparty option, though the process will be a bit less user friendly.

Get a session token

  1. Open and sign into the Slack customization page. Check that you end up on the correct team.
  2. Type javascript: in the address field in the browser and paste this code after: window.prompt("Session token:", TS.boot_data.api_token)
  3. A prompt with the token will appear. Copy the token, return to WeeChat and run /slack register <token>.
  4. Reload the script with /python reload slack.

Optional: Connecting to multiple teams

You can run the register command multiple times to connect to multiple teams. If you set the token option yourself, you should separate the tokens with commas.

/set plugins.var.python.slack.slack_api_token <token1>,<token2>,<token3>

Optional: Secure the tokens

The tokens you add will be stored as plain text in the option plugins.var.python.slack.slack_api_token. If you don't want to store your API token in plain text you can use the secure features of WeeChat:

/secure passphrase this is a super secret password
/secure set slack_token <YOUR_SLACK_TOKEN>
/set plugins.var.python.slack.slack_api_token ${sec.data.slack_token}

Note that you will have to move your tokens manually from plugins.var.python.slack.slack_api_token to the secure variable after each time you run /slack register <code>.

Commands and options

For the available options see docs/Options.md or run this command:

/set slack

Most options require that you reload the script with /python reload slack after changing it to take effect.

For the available commands see docs/Commands.md or run this command:

/slack help

In addition to the commands listed with /slack help, most normal IRC commands, like /join, /part, /query, /msg, /me, /topic, /away and /whois work normally. See WeeChat's documentation or /help <cmd> if you are unfamiliar with these.

There are also some special messages you can send:

Modify previous message using regex:

s/old text/new text/

Modify 3rd previous message using regex:

3s/old text/new text/

The regex also supports the flags g for replacing all instances, i for ignoring case, m for making ^ and $ match the start/end of each line and s for making . match a newline too. Use them by appending one or more of them to the regex:

s/old text/new text/gi

Delete previous message:

s///

Add a reaction to the nth last message. The number can be omitted and defaults to the last message. The + can be replaced with a - to remove a reaction instead.

3+:smile:

To send a command as a normal message instead of performing the action, prefix it with a slash or a space, like so:

//slack
 s/a/b/

Threads

Start a new thread on the most recent message The number indicates which message in the buffer to reply to, in reverse time order:

/reply 1 here is a threaded reply to the most recent message!

Open an existing thread as a channel. The argument is the thread identifier, which is printed in square brackets with every threaded message in a channel:

/thread af8

To access the last thread in a channel a shorthand is available:

/thread

Label a thread with a memorable name. The above command will open a channel called af8, but perhaps you want to call it "meetingnotes". To do so, select that buffer and type:

/label meetingnotes

Note: labels do not persist once a thread buffer is closed

Emoji characters and tab completions of emoji names

To enable rendering of emoji characters and tab completion of emoji names, copy or symlink the weemoji.json file to your weechat config directory (e.g. ~/.weechat). If doing this after starting wee-slack, you will have to reload it by running /python reload slack. Then append |%(emoji) to the weechat.completion.default_template config option, e.g. like this:

/set weechat.completion.default_template "%(nicks)|%(irc_channels)|%(emoji)"

Emoji names can be completed by typing colon and the start of the emoji name and pressing tab.

User group tab completions

To enable tab completions for usergroups append |%(usergroups) to the weechat.completion.default_template config option, e.g. like this:

/set weechat.completion.default_template "%(nicks)|%(irc_channels)|%(usergroups)"

If you already added %(emoji) to this config option, like described in the last section, make sure not to overwrite that. The usergroup will appear in the same format as nicks, like the following: @marketing, where marketing is the usergroup handle.

Cursor and mouse mode

The cursor mode and mouse mode can be used to interact with older messages, for editing, deleting, reacting and replying to a message. Mouse mode can be toggled by pressing Alt+m and cursor mode can be entered by running /cursor (see /help cursor).

If mouse mode is enabled, the default behavior when right-clicking on a message is to paste its id in the input. It can be used in /reply, s/ substitution/deletion and in +:emoji: commands instead of a message number. It can also be used as an argument to the /slack linkarchive command.

In cursor mode, the M key achieves the same result (memo: the default for weechat is to paste the message with m, M simply copies the id). In addition, R will prepare a /reply id and D will delete the message (provided it's yours). T will open the thread associated to a message, equivalent to /thread id L will call the /slack linkarchive command behind the hood and paste it to the current input.

Please see weechat's documentation about how to use the cursor mode or adapt the bindings to your preference.

Default key bindings:

/key bindctxt mouse @chat(python.*):button2 hsignal:slack_mouse
/key bindctxt cursor @chat(python.*):D hsignal:slack_cursor_delete
/key bindctxt cursor @chat(python.*):L hsignal:slack_cursor_linkarchive
/key bindctxt cursor @chat(python.*):M hsignal:slack_cursor_message
/key bindctxt cursor @chat(python.*):R hsignal:slack_cursor_reply
/key bindctxt cursor @chat(python.*):T hsignal:slack_cursor_thread

Note that if these keys are already defined, they will not be overwritten by wee-slack. In that case, you will have to define your own key bindings by running the above commands modified to your liking.

hsignals slack_mouse and slack_cursor_message currently have the same meaning but may be subject to evolutions.

Removing a team

You may remove a team by removing its token from the dedicated comma-separated list:

/set plugins.var.python.slack.slack_api_token "xoxp-XXXXXXXX,xoxp-XXXXXXXX"

You can use tab completion after the key to complete the current value. To see which token belongs to which team, run /slack teams.

After removing the token, you have to reload wee-slack with /python reload slack.

Optional settings

Show typing notification in main bar (slack_typing_notice):

/set weechat.bar.status.items [buffer_count],[buffer_plugin],buffer_number+:+buffer_name+{buffer_nicklist_count}+buffer_filter,[hotlist],completion,scroll,slack_typing_notice

Show channel name in hotlist after activity

/set weechat.look.hotlist_names_level 14

FAQ

How do I keep the buffers sorted alphabetically or with a custom order?

Install the script autosort.py by running /script install autosort.py. This will keep your buffer list sorted alphabetically by default. If you want to customize it, run /help autosort.

How do I group the buffers by team in the buffer list?

Run /set irc.look.server_buffer independent and install the autosort.py script mentioned in the previous question.

How can I get system wide notifications for messages?

Install one of the notify scripts. Note that not all scripts work with wee-slack. For local notifications, lnotify.py is known to work for Linux, and notification_center.py for macOS.

How do I send messages with multiple lines?

You have to install a script to be able to send multiple lines, e.g. the multiline.pl script with: /script install multiline.pl

By default it will wait for one second after you press enter, and if you type another character in that period, it will insert the character on a newline, and if you don't type anything it will send the message. If you rather want to use a separate key to insert a newline, and have the enter key send the message immediately, you can run these commands:

/set plugins.var.perl.multiline.magic_paste_only on
/key bind meta-ctrl-M /input insert \n

This will bind meta-enter (which is usually alt-enter) to insert the newline. Replace meta-ctrl-M with something else if you want to use a different key combination.

The multiline.pl script will also let you edit pasted text which incudes newlines before you send the message. If this is not working, you may try to run the commands below. At least in the kitty terminal, it won't work by default, but should work after running these commands:

/set plugins.var.perl.multiline.weechat_paste_fix "off"
/key bind ctrl-J /input magic_enter

You may also want to disable weechats paste prompt, since that is not necessary when using multiline.pl:

/set weechat.look.paste_max_lines -1

Known issues

Not all issues are listed here (see issues for all), but these are some noteworthy:

  • If you set background_load_all_history to false:
    • Shared channels and channels that has been converted from public to private will not be shown as unread when wee-slack loads, even if there are unread messages. Messages which arrive after wee-slack has loaded however will mark the channel as unread.
    • If messages arrive while the connection to Slack is lost (e.g. during suspend), they will not appear in the hotlist.
  • If you use an OAuth token or a legacy token instead of a session token:
    • Threads, shared channels and channels that has been converted from public to private can only be marked as read locally, it won't sync to Slack. This means they will be unread again after reloading the script.

Development

To run the tests, create a virtualenv and pip install from the requirements.txt. Then pytest to run them locally.

Enable debug mode and change debug level (default 3, decrease to increase logging and vice versa):

/set plugins.var.python.slack.debug_mode on
/set plugins.var.python.slack.debug_level 2

Dump the JSON responses in /tmp/weeslack-debug/. Requires a script reload.

/set plugins.var.python.slack.record_events true
