Upload files and snippets to Slack chat from the command-line.
Log in to your slack.com account and get your API token from https://api.slack.com/.
gem install slackcat
export SLACK_TOKEN=<your api token>
echo 'hello world' | slackcat -c <channel>
slackcat is used similarly to unix cat: read data from STDIN or
list filenames as arguments. Multiple files will be concatenated.
Environment variables:
SLACK_TOKEN: your token from https://api.slack.com/.SLACK_CHANNELS: default comma-separated list of channel names to share files
Command-line options:
--token, -k: Slack API token
--channels, -c: Channels to share into
--filetype, -t: File type identifier
--title, -T: Title of file
--filename, -n: Filename of file
--initial-comment, -i: Initial comment to add
--help, -h: Show this message
File uploads to slack are private by default. If you list channels, content will be shared to them.
Upload contents of buffer:
:%! slackcat
Upload contents of region:
M-| slackcat
To make a named function:
(setenv "SLACK_TOKEN" "<your api token>")
(setenv "SLACK_CHANNELS" "<channel list")
(defun slackcat (&optional b e)
"Upload contents of region to slack chat."
(interactive "r")
(shell-command-on-region b e "slackcat"))
