Command Line Interface Tweeter

Config

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 ~/.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

Installation

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 haskell stack; on unix systems this is as simple as

wget -qO- https://get.haskellstack.org/ | sh

Then type stack install tweet-hs it will generate an executable called tweet, which is what we want.

Use

View Profiles and timelines

To get your timeline, simply type:

tweet view

To view a user's profile, type e.g.

tweet user pinepapplesmear --color

Sending tweets

To tweet from stderr, run a command that pipes stderr to stdin, i.e.

YOUR_BUILD_COMMAND 2>&1 >/dev/null | tweet input

The tweet executable reads from stdIn only, but you can view the options (replies, number of tweets to thread, etc.) with

tweet --help

This script powers the twitter account @my_build_errors for instance. There's an example bash script for in bash/example

Viewing your timeline

You can also use

tweet view

or

tweet view --color

to view your own timeline.

Completions

The directory bash/ has a mkCompletions script to allow command completions for your convenice.

Library

A haskell package is included. It's fairly easy to use once you have the credentials set up, with two main functions: thread and basicTweet: the first for threading your own tweets or replying to someone else's and the second for just tweeting.

Finer details

The function tweetData will tweet an object of type Tweet. Its use is pretty self-explanatory, but how to best form Tweets is not immediately obvious.

Tweet is an instance of Default so you can use def to get an empty tweet replying to nobody and not fetching extended user data. This is especially useful if you want to use lenses and avoid ugly record syntax, e.g.

set status "This is the new status field" $ def

will give you a Tweet with sensible defaults and the desired text.
