Build Status


Slacker is a tool designed to make it easier to do admin tasks and general utility for several workspaces (teams). It supports a REPL for inputting and evaluating commands, along with a CLI for running a single command.

First Run

The first invocation of Slacker requires to setup a workspace using the --init argument:

% ./ --init
Input workspace token: ****************************************************************************
Added new workspace 'myworkspace' to config and made it active.
You can now run slacker normally.

Slacker is ready for use afterwards with "myworkspace" as the active workspace. Note that it is recommended to employ a user token, not a bot token!

Tokens can be created here. Never share these tokens!

CLI Usage

usage: [options] [-- command [args..]]

Useful Slack utilities and REPL.

optional arguments:
  -h, --help     show this help message and exit
  -V, --version  show program's version number and exit
  -v, --verbose  Sets the log level to DEBUG for this session.
  -q, --quiet    Disable stdout logging
  --init         Interactively initialize config and add workspace and API
  --check        Checks that all commands are valid.
  --no-tests     Do not do API and auth tests at startup.

Most commands support -h|--help to see how they work. By passing '--', it
signals that Slacker arguments end and a single command and arguments begin.
Slacker will exit after running that command.

Development Environment

Slacker is written in Python 3 and the required modules to be installed can be found in requirements.txt.

To setup a virtual development environment that doesn't pollute the general system it is expected that virtualenv for Python 3+ is installed.

Run make setup to install required modules to ".venv" in the root of the repository, and issue source .venv/bin/activate to activate the environment. From here, the python, python3, pip etc. will map to ".venv" and the modules installed into it.


A Dockerfile is provided to quickly get up an running with Slacker. To build the Docker image it is recommended to use the docker target in the Makefile make docker, which creates image slacker:local. Start the slacker container by executing By default the script will drop you into the REPL, but slacker commands can be given directly to the script.

% ./ -- files.list -c 10

Note: slacker writes a configuration file to disk (~/.slacker). In order to keep the configuration file between subsequent runs the local volume mount in the container is required.
