Sclack

The best CLI client for Slack, because everything is terrible!

Disclaimer

The project is still under alpha, there are lots of things already done, but there is also a lot of work to do! If you want to help, please contact me under marcelocamargo@linuxmail.org or create an issue! Working in community, we can soon have a CLI client as complete as the web one!

Setup

Using legacy token

First of all get a Slack token here. Use, create or request a token for each workspace that you'll use on Sclack. Not all workspaces allow you to generate a legacy token, so sometimes you'll need to ask for the administrator to enable the feature.

Without a legacy token

Unfortunately some serious hoops need to be jumped through to use a non-legacy token.

Go to https://api.slack.com/apps
Click "Create new app"
Give the app a name (maybe "Sclack") and select the server you'd like to use
Go to "Permissions" and add a new redirect URL: http://localhost:8080
Go back to the previous page, you'll be able to see "Client ID" (you will also need the "Client Secret" later). Use this to fill in this url:

    https://slack.com/oauth/authorize?client_id=[Client ID here]&scope=client

Go to that URL in your browser, and authorize the app
The page will redirect to a blank page. Look at the URL and copy the code= parameter (http://localhost:8080?code=[code-will-be-here]&state=)
Now using the copied code, as well as the "Client ID" and "Client Secret" from the app page, fill in and execute this command:

    curl -s "https://slack.com/api/oauth.access?client_id=[client id here]&client_secret=[client secret here]&code=[code here]"

Finally, copy the access_token from the response (should start with xoxs-). This is your new auth token for Sclack

Optional Dependencies

Nerd Fonts

Sclack seems better when used with a Nerd Font. Using them is completely optional, but it is how some Sclack icons are possible. Personally, I use Fira Code Nerd Font. Download, install and set as the default font of your terminal emulator.

libcaca

Sclack uses caca-utils to create ANSI/VT100 + ASCII versions of pictures and render them. Images will only be rendered if both caca-utils is installed and features.pictures is configured to true. To install caca-utils, just run sudo apt-get install caca-utils on Debian and brew install libcaca --with-imlib2 on OS X.

Installation

From Source

Ensure you have Python 3.6 or superior version.

pip

git clone https://github.com/haskellcamargo/sclack.git
cd sclack
python setup.py --user install
sclack

pipenv

git clone https://github.com/haskellcamargo/sclack.git
cd sclack
export PIPENV_VENV_IN_PROJECT=1
pipenv install # install deps
pipenv run python -m sclack

From Binary

If you don't have Python installed, you can get the compiled binary for Sclack on releases page. Versions will be available for Linux x86/x64 and OS X.

Running

Run ./app.py after giving the correct permissions. If you don't have a ~/.sclack file, you can generate one here by providing your workspace token. You can change the theme, enable or disable images, emojis, markdown, configure keyboards and everything else from this file. Important: use q to quit!

Your ~/.sclack file will look like:

{
    "colors": 256,
    "theme": "default",
    "keymap": {
        "cursor_down": "j",
        "cursor_left": "h",

    },
    "logging": {},
    "workspaces": {

    }
}

Multiple workspaces

If you want to, you can use Sclack in multiple workspaces. You can have at most 9 workspaces defined inside workspaces:

...
    "workspaces": {
        "default": "wow-such-secret",
        "another": "wow-another-secret"
    }
...

You can use the keys from 1 up to 9 to switch workspaces or event right-click the indicator:

Quick Switcher

You can use ctrl k (or your custom shortcut) to navigate in your DMs and channels.

Set snooze

You can use ctrl d (or your custom shortcut) to set snooze time.

Get permalink

Focus on message and press r (or your custom shortcut) to get permalink (Quote message) and it will be put into your chat box.

Default keybindings

...
  "keymap": {
    "cursor_down": "j",
    "cursor_left": "h",
    "cursor_right": "l",

To test your notification availability, trigger below command, if you can see notification you can use this feature

python sclack/notification.py

logging

Sclack uses the python logging module to display debug messages. Logged messages can be configured in the "logging" section of the configuration file. The specified logging configuration is given to logging.config.DictConfig.

"logging": {
    "formatters": {
        "default": {
            "style": "{",
            "format": "[{levelname}] {message} - {name}"
        }
    },
    "handlers": {
        "file": {
            "class": "logging.FileHandler",
            "filename": "/tmp/sclack.log",
            "mode": "w",
            "formatter": "default"
        }
    },
    "root": {
        "level": "DEBUG",
        "handlers": ["file"]
    }
}
