CodeSnip

CodeSnip is an open source code bank for storing and viewing code snippets. It not only manages, displays and manipulates your own code snippets but it can also incorporate snippets downloaded from the online DelphiDabbler Code Snippets Database. > CodeSnip's source code is now developed over on GitHub: https://github.com/delphidabbler/codesnip Designed with Pascal code in mind, CodeSnip enables Delphi or Free Pascal code snippets to be test-compiled with any installed Delphi or Free Pascal compiler and results to be reported. Use this feature to validate the syntax of code without switching to your compiler. Compilable Pascal units containing selected snippets can be generated. Code in other languages can be stored in CodeSnip although the source file generation and compiler checking features will not be available. Compilable Pascal units of selected snippets can be generated. Selected snippets can also be exported and shared with other CodeSnip users.

Releasing units without source code

It can be useful to release a FreePascal unit without publishing its source code: * The source code contains proprietary information. * In teaching, because you want to force students to use a unit by its interface (contract) only, and not by looking at its implementation.

Bug Finder

This project born a few years ago when I encountered a fatal bug on a production environment, unfortunately not replicable on my development machine. I spent many time finding a solution, using also freeware and commercial third-party tools and libraries, but none helped me because the bug crashed the process, and no of the above tools could be able to catch the exception before the process dying. Also, it was not possible to install a development environment onto the production machines, so the only solution was to develop a debugger which didn't need any user/developer interaction. I used many open source resources, then I decided to make the Bug Finder an open source project. It is built over a pluggable architecture to support other languages different from Borland Delphi (the one I used to develop my faulting application and the Bug Finder too). Here is the article http://www.codeproject.com/Articles/602794/Bug-Finder-a-real-Win32-extensible-passive-debugge .

Dev-C++ for Homeworks

Orwell Dev-C++ with author authentication. Perfect for student homeworks, if you don't want your students to copy their homework files from others. Authenticated files are regular source files with student's name and a security hash added at the end. Any cheating attempt by copying in the files / changing name will invalidate the hash and can be detected by the teacher. In addition, paste in authenticated files is only allowed from one's own files. The CheckHash.exe tool checks the hash and reports the authentication status of of all .cpp files in the current directory. This tool is intended for teachers. How to install: simply download a Setup Release and install it. Alternatively, it is possible to just overwrite devcpp.exe in the original Dev-Cpp installation folder with the one in the zip release, and also add Auth.dll in the same folder. Dev-C++ for Homeworks is based on Orwell Dev-C++ software. Releases follow upstream releases.

pascal p5c

p5c is a fast portable iso standard pascal compiler. It is derived from the pascal p5 compiler and creates gnu c code instead of p-code. This makes it very fast since it uses gcc to generate native code. p5c is multi platform - it is easy to get up and running since you only need gcc to start. Using gcc enables extra tools like a static analyser and code coverage analyser. Execution profiling described in the blog here -> https://sourceforge.net/p/pascal-p5c/blog/2017/07/how-to-use-profiling-to-speed-up-p5c-pascal-programs It extends p5 by adding arbitrary set limits and conformant arrays. The project also contains p5x - pascal with extensions to the standard pascal language (underscores allowed in identifiers, otherwise in case statement, constant expressions, etc)

Spintax Studio

Spintax Studio is a native Windows editor for spintax templates: two panes, your template on the left, its live render on the right. Preview and the valid/invalid verdict come from the real spintax engine inside the application, not from a second parser. Diagnostics carry line and column positions and link to the built-in help; panels list variable definitions, references, session values and #include targets with their resolution status. Generate variants locally, reproduce them with a seed, and export as plain text, an XLSX workbook, or one file per variant. Offline by default: no account, no telemetry, no Node.js, PHP or Python runtime — one self-contained executable. Optional AI drafting is off until you turn it on and talks only to the endpoint you configure, with your own key when it needs one. Interface and built-in help in 14 languages. Free and open source, GPL-3.0-or-later. The SPINTAX language and its engine family are documented at spintax.net.

Transposer

Transposer converts the chords of a text file which contains the lyrics and chords for a song into whatever key the user desires. Version 1.0 no new features, just some UI cleanup. No bugs reported since last BETA, so nothing to fix at this point. (0.56) was the first with a mechanism for creating an ignore list of words which might get transposed if they are on a line by themselves, such as, "ending". This word is typically made of characters which are valid chord characters that would otherwise be transposed. There are two editing panes in the main window. One is for the original song, and the other is for the transposed song. Earlier versions of this program were command line only (CLI), then I used QT to augment my C++ source to create a GUI. This project is now developed in Lazarus, using a collaborative approach. I (abudeveloper) and my son (iamslinger) are working together on this project.
