Components and Libraries


5dpo Component Library is a set of components developed by the 5dpo Robotic Soccer Team. It provides a visual serial port (TSdpoSerial) implementation of Synaser, an IEEE1394 camera (TSdpoVideo1394) component, an UVC video driver component (TSdpoVideo4L2) for webcams, a Gtk fast painting form (TSdpoFastForm) and a Joystick (TSdpoJoystick) component.


Audorra is a digital audio library for Delphi and Freepascal. Using a flexible plugin architecture, it allows you to exchange the audio backend (e.g. WaveOut, OpenAL), add protocol classes (e.g. file, http) and decoders.


BrasLib is a new report component for Lazarus under development by brazilian programmers.

Brook Framework

Brook framework is the perfect Free Pascal framework for your web applications. It's pure Pascal. You don't need to leave your preferred programming language. It's complete: simple actions or configurable actions for database access, advanced routing features, wizard for Lazarus, support for internationalization, high compatibility with JSON structures, easy and elegant REST implementation, plugins for varied needs, extensible and decoupled brokers... In fact, you have several reasons to adopt Brook as your web development framework.


  • Advanced routes management - Actions are performed by means of routes. The application replies to requests that pass information through routes. Implementing this could involve a bunch of boring tests, but Brook knows how to receive a request and choose the correct URL and the correct method to reply to it. Using Brook, you have shorter and friendlier code to handle your routes.
  • Integrated data persistance - Brook can work together well with other frameworks. Brook offers a table object where data can be handled. Less instantiations, less coding, with an elegant syntax. These are advantages of Brook, but in this case, it's a special virtue of Greyhound, the partner project responsible for handling databases. Within Brook, scope, there are other database layers available for specific usages but for most cases, Greyhound is the best one.
  • JSON native support - JSON structures are largely used by JavaScript. JSON is widespred in the web for data exchange purposes. You will really appreciate Brooks' good JSON support.
  • REST architecture support - If you didn't come from the web development world, you won't understand the power of REST. REST is not a software component or a tool kit, but an idea. An idea able to simplify and standardize data requests and replies. Brook is powerful even if you don't use REST -- but you will want to use it.
  • Lazarus wizards for installation and usage - No, Brook didn't forget Lazarus users. With Lazarus, development is easier; with the Brook wizards, only a few clicks are required to start and configure your Brook projects.
  • Plugins for varied needs - In the full Brook package, everything is included: mail sending, HTTP utilities, templating, algebraic expression processing, RSS reading and writing and much more. You can see the whole list of plugins here.

CUPS for lazarus

Olivier Guilbaud CUPS for lazarus project is developing the bindings for pascal to use the CUPS (Common UNIX Printing System) libraries. With some dialogs for select printer, setup printer, setup printer jobs.

fpctwit is a plurk, Twitter and OAuthv1 library with example programs (console and GUI). It's a framework that implements the Oauthv1 authorization protocol.

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

CheckRide is an open source remote control tool. It lets you take over the screen and keyboard of a remote computer. The helped person only needs to run the program, no firewall/router changes necessary. The helper does need to forward a port in her router. Features:

  • No configuration required for client, just click and be helped
  • 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.

FreePascal 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
  • 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.
