Welcome to the Lazarus and Free Pascal wiki
The goal of this wiki is to be a knowledge base for Free Pascal/Lazarus and related projects.
Free Pascal already has good user documentation in several formats, but FPC developer information, organizational information and subjects not yet properly documented are collected in this wiki.
Lazarus, on the other hand, has some gaps in the user documentation. So this area was created as an “open document” or “wiki” where anyone can edit and add content.
The wiki speeds things by making it possible to make changes and additions with a browser! For tutorials, please take a look at the Wikipedia Tutorial. A Sand Box is available for practice. If you have any problems, please post a bug report on the Lazarus bug tracker. You can also leave a note or suggestion on our Site Feedback page.
For the Lazarus project history, see the History page.
Free Pascal Documentation
- FPC developer documentation
- Contains available documentation for developers and other contributors of the Free Pascal Compiler, such as people involved in translation of messages to other languages, a list of pascal bindings, organizational information, procedure for FPC releases, ToDo lists, etc.
- Lazarus Documentation
- All the available documentation and tutorials for the Lazarus IDE (including the Free Pascal Compiler manuals) can be found on the Lazarus Documentation page. Installation instructions are also available. Many of the pages are "works in progress" so please feel free to add your experience to these sections. You can also create a personal page with contact information, if you wish.
All currently available components and packages are available on the Lazarus-CCR Sourceforge files area. Current versions of Lazarus can be found at The Lazarus Sourceforge site, while FPC can be downloaded from FreePascal.org. Installation help is available on the Installing Lazarus wiki page. Additional documentation on these packages can also be found on the Components and Code examples wiki page if the person who contributed the code created one there. The Compiler and a lot of contributed code can be found on the Free Pascal Compiler download mirrors and on the Lazarus IDE website. Lazarus Snapshots download locations can be found here.
Who is working on what?
If you're currently converting a component or library, or you need something converted, please post it on the Current conversion projects page. These postings will help guide developers who want to convert components that are in demand, as well as prevent the duplication of two people converting the same package.
References, Links and Resources
News and information about the status of the Lazarus IDE can be found on the Lazarus IDE website. Ideas, todos, and other plans can be found at Lazarus Development Process page. Releases of the Lazarus IDE and Free Pascal compiler can be downloaded from there. The Lazarus file area also has the latest packages of the compiler and IDE available for download.
Active Lazarus Projects
Our current listing of Projects using Lazarus with publicly accessible websites and Lazarus related files to download.
In the Lazarus Application Gallery you can see some screenshots of applications created with Lazarus.
Super Sites and Link Farms
Our current collection of Delphi/Kylix related sites can be found on our Page Of Code Sites. Please add to it if you know of a good site that hasn't been listed yet.
Specialized Search Engines
There are some outstanding search and knowledge bases online that can be a great help for learning new techniques and solving problems. Tamarack Associates operates a fast search engine specifically for the Borland usenet archives. Mer Systems Inc. provides a similar search engine. Another outstanding source of information along with a sitewide search capability is Earl F. Glynn's Computer Lab and Reference Library.
Marketing Case Studies
An opportunity for Lazarus users to explain why Lazarus is the IDE of choice.
Presenting FPC/Lazarus at a trade show and at contests
FPC/Lazarus was presented with a booth at the Systems 2005, the Systems 2006 and the Systems 2007 in Munich. Based on the experiences from these trade shows, a collection of information to help future preparations for a trade show booth was built. Lazarus and related projects have also participated in a number of Contests, and a wiki page was prepared to help future contests enrollments.
