Slackcat is a simple commandline utility to post snippets to Slack.
Download the latest release for your platform:
curl -Lo slackcat https://github.com/bcicen/slackcat/releases/download/1.7.2/slackcat-1.7.2-$(uname -s)-amd64
sudo mv slackcat /usr/local/bin/
sudo chmod +x /usr/local/bin/slackcatslackcat is also available via homebrew:
brew install slackcat
To optionally build slackcat from source, ensure you have dep installed and run:
go get github.com/bcicen/slackcat && \
cd $GOPATH/src/github.com/bcicen/slackcat && \
make build
You must use GNU make for the build to work correctly. If your platform does not install GNU make as make (i.e. OpenBSD) then you will need to install gmake and run:
go get github.com/bcicen/slackcat && \
cd $GOPATH/src/github.com/bcicen/slackcat && \
gmake build
Generate an initial config, or add a new team token with:
slackcat --configureYou'll be prompted for a team nickname and a new browser window will be opened for you to confirm the request via Slack. Provide the returned token to slackcat when prompted, and you're ready to go!
For configuring multiple teams and default channels, see Configuration Guide.
