fpctwitGUI is a Lazarus application that demonstrates use of the included TTwitter/TOauth1 libraries. It demonstrates getting public and private timeline tweets, getting user info, and tweeting.
It also demonstrates use of the Blowfish encryption units to obfuscate sensitive configuration data.
The Twitter library uses the Synapse network units for easy communication; it supports OAuthv1 secure authentication and TLS encryption. The library uses modified fpJSON units (or the FPC units if compiling with 2.7.1 or later) to allow getting UTF8 data out of the JSON data with Tweets returned from Twitter. The GUI does not show this, but a text mode demo program shows how to use the OOB/PIN authentication method included in the Twitter library to authorize the application for Twitter if it hasn't already been authorized.
The Twitter library uses the included OAuth1 unit that provides OAuth1 authentication. This authentication mechanism is also used for other service providers such as Yahoo.
The applications and libraries are distributed under a very liberal license (my code under MIT license) which allows commercial use as well as interoperability with GPL programs.
See Projects using Lazarus: fpctwit for more details.
