I've finished a basic Twitter application and OAuth v1 library under an
MIT license (happy to relicense under the Synapse license).
Code can be downloaded using Mercurial or as a zip from
While not perfect yet, the application demonstrates:
- Authenticating to Twitter using existing credentials (ConsumerKey,
ConsumerSecret, Auth_token, Auth_secret)
- Authenticating to Twitter using Out Of Band/PIN authentication using a
callback in the application that sends the user to an URL. User
authorizes application and gets a PIN which he enters in the application.
- Reading public and own timeline
- Parsing tweets from JSON data
- Tweeting a message
- Showing all tweets that come through the streaming API
Currently only run on Windows; it will be probably need some tweaks for
line ending issues on Linux/OSX.
Built for FPC (on 2.6.1); don't know how hard it would be to port this
Comments and improvements to the code are always welcome - I'm not a
programming guru, but got this done with some help... ;)
To implement streaming support (Twitter sends a stream of tweets inside
a single HTTP response), I had to modify Synapse httpsend to be able to
override ReadUnknown (see patch). I'd be very happy if that patch could
Added as Feature Request 3536896 [Patch] Allow httpsend.Readunknown
override in SourceForge with the same patch as attachment.
