Generate a token to authorize access to your twitter account by following the guide here
Then place your API keys and OAuth tokens in a file (default is ~/.cred), separated by a line break:
api-key: API_KEY_HERE
api-sec: API_SECRET_HERE
tok: OAUTH_TOKEN_HERE
tok-sec: TOKEN_SECRET_HERE
Note that the labels must in the correct order, and separated from the keys with whitespace.
If you're on Linux/Windows the best way is probably to download the binaries from the releases page here.
To build from source, install cargo via rustup; on unix systems this is as simple as
curl https://sh.rustup.rs -sSf | sh
Then type cargo install clit-rs.
To get your profile, simply type:
tw user
To view a user's profile, type e.g.
tw user pinepapplesmear
If you have any problems along the way:
tw --help
tw send "YOUR_TWEET_TEXT"
You can also use
tw view
to view your own timeline.
A library is included. It's fairly easy to use once you have the credentials set up, with three functions: one to post a status, one to get your timeline, and one to get a user profile.
