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.

pascal-p5

This is the 5th version of the Pascal-P compiler from Zurich. This is the Pascal-P4 compiler modified to be ISO 7185 Pascal compilant, both in the the implementation language, and in the language it processes. Pascal-P was an implementation kit, created between 1972 and 1974, for the original language Pascal. The source for the original compiler was passed around and modified quite a bit, but Niklaus Wirth noted that it was very popular, and represented a good method to popularize the language. He gathered the source into a clean version called Pascal-P2. The Zurich group then created an improved version called Pascal-P4. You can find all of the Pascal-P versions here in sourceforge: https://sourceforge.net/projects/pascal-s/ https://sourceforge.net/projects/pascal-p2/ https://sourceforge.net/projects/pascalp4/ https://sourceforge.net/projects/pascalp5/ https://sourceforge.net/projects/pascal-p6/

macOS FPC + Lazarus daily snapshots

IGNORE THE BIG GREEN DOWNLOAD BUTTON: choose file in Files area These macOS snapshots of the development branches are generated automatically. All I can say is that the compiler found the source good enough to compile. YOU ARE USING COMPLETELY UNTESTED SOFTWARE. Caveat Utilitor! 1. Move lazarus-src to your home directory 2. Open a Terminal 3. Change to lazarus-src and run the command: xattr -drv com.apple.quarantine * 4. Use a script to start Lazarus like: #!/bin/sh open ~/lazarus-src/lazarus.app --args "--pcp=~/.laz_main" There is also a daily FPC development snapshot for ARM64. 1. Move fpc-src to your home directory 2. Install with a script like: #!/bin/sh cd ~/fpc-src xattr -drv com.apple.quarantine * sudo make FPC=$PWD/ppca64 OPT="-ap -FD/Library/Developer/CommandLineTools/usr/bin -XR/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk" install Adjust links in /usr/local/bin to point to 3.3.1 or choose compiler in Lazarus

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)
