The OAuth library (and the Twitter and plurk libraries using that) uses the Synapse network units for easy communication, but can easily be adapted for other network layers. It supports OAuthv1 secure authentication and SSL/TLS encryption.
The library uses modified fpJSON units to allow getting UTF8 data out of the JSON data with Tweets returned from Twitter (for FPC trunk, the FPC units are used as Michael Van Canneyt added support for UTF8 in trunk).
Functionality includes: getting tweets using the Search API, tweeting, getting username info, authenticating using PIN/OOB or preset credentials (consumerkey+secret,authtoken+secret).
The twitter console demo, fpctwit, also demonstrates the Streaming API to process and show Tweets and deletion messages.
There is a plurk console demo that demonstrates the functionality in the plurk library.
The plurk and Twitter libraries use the included OAuth1 unit that provides OAuth1 authentication. This authentication mechanism is also used for other service providers.
The Lazarus demo application, imaginatively named fpctwitGUI, is shown in the Lazarus Application Gallery at fpctwitGUI

- Helper can use the tool to create a custom version of CheckRide that connects to her server. This way, the helped party only needs to download and run one program. Alternatively, the helper can distribute a configuration file for the same purpose.
- Supports Windows UAC
- Encrypted connection
- Uses UltraVNC and stunnel programs to provide remote control and encryption
- Supports Windows helped persons and helpers on Windows (CheckRideHelper.exe) and Linux (stunnel/vncviewer), probably OSX, too.
- Can be used for free, both commercially and non-commercially. CheckRide wrapper is MIT licensed freeware: it can also be incorporated in commercial programs.
Technical details: it uses an UltraVNC winvnc reverse connection and stunnel to create an encrypted connection. You can realize this by just using stunnel and vncviewer, so the helper side should be usable on Linux and OSX, too. For now, CheckRide itself has only been compiled on Windows; it will need some changes for other operating systems.
Free Pascal techniques that are used:
- Controlling external programs
- Installing/deinstalling Windows services
- "Poor man's resource": adding zip files after exe with configuration data, UltraVNC, stunnel details
- Zipping/unzipping files
- Using a manifest to request Administrator privileges/elevation
- Handling command line options; multiple configuration mechanisms (embedded config file, config file in application directory, command line options)
More details: see CheckRide wiki.
