Features
--------
* [Threads](#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

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](https://my.slack.com/customize). Check that you end up on the correct team.
2. Open the developer console (`Ctrl+Shift+J`/`Cmd+Opt+J` in Chrome and `Ctrl+Shift+K`/`Cmd+Opt+K` in Firefox).
3. Paste and run this code: `window.prompt("Session token:", TS.boot_data.api_token)`
4. A prompt with the token will appear. Copy the token, return to WeeChat and run `/slack register <token>`.
5. 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 ${sec.data.slack_token}
```
Note that you will have to move your tokens manually from
`plugins.var.python.slack.slack_api_token` to the secure variable after each
time you run `/slack register <code>`.
Commands and options
--------------------
For the available options see [docs/Options.md](docs/Options.md) or run this command:
```
/set slack
```
Most options require that you reload the script with `/python reload slack`
after changing it to take effect.
For the available commands see [docs/Commands.md](docs/Commands.md) or run this command:
```
/slack help
```
In addition to the commands listed with `/slack help`, most normal IRC
commands, like `/join`, `/part`, `/query`, `/msg`, `/me`, `/topic`, `/away` and
`/whois` work normally. See [WeeChat's
documentation](https://weechat.org/files/doc/stable/weechat_user.en.html) or
`/help <cmd>` if you are unfamiliar with these.
There are also some special messages you can send:
Modify previous message using regex:
```
s/old text/new text/
```
Modify 3rd previous message using regex:
```
3s/old text/new text/
```
The regex also supports the flags `g` for replacing all instances, `i` for
ignoring case, `m` for making `^` and `$` 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`](https://github.com/wee-slack/wee-slack/blob/master/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](https://weechat.org/files/doc/stable/weechat_user.en.html#key_bindings_cursor_context) or [adapt the bindings](https://weechat.org/files/doc/stable/weechat_user.en.html#command_weechat_key) 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](https://weechat.org/scripts/source/autosort.py.html/) 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](https://weechat.org/scripts/source/autosort.py.html/) script
mentioned in the previous question.
### How can I get system wide notifications for messages?
#### Local notifications on Linux
Use [this trigger](https://github.com/weechat/weechat/wiki/Triggers#show-a-libnotify-desktop-notification-via-notify-send).
You need the `notify-send` command, or alternatively replace it with another
command in the trigger.
#### Local notifications on macOS
Use [the notification_center.py script](https://weechat.org/scripts/source/notification_center.py.html/). You can install it with `/script install notification_center.py`.
#### Remote notifications
There are many scripts in the [scripts repo](https://weechat.org/scripts/tag/notify/)
for various use cases. Note that not all may work with wee-slack, so you will
have to test them.
### 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](https://github.com/wee-slack/wee-slack/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
```
