Welcome to pas2js

Pas2js is an open source Pascal to JavaScript transpiler. It parses Object Pascal and emits JavaScript.

Official site: http://wiki.freepascal.org/pas2js

Directories

packages - source files needed to compile pas2js programs demo - examples bin - output folder for binaries, e.g. pas2js.exe compiler - source files to compile the compiler units - output folder of compiler ppu/o files utils - utilities

Building

  1. Install the Free Pascal compiler (fpc), 3.0.4 or better, 32 or 64bit. Either from their website https://www.freepascal.org/download.html Or via Lazarus http://wiki.freepascal.org/Getting_Lazarus Or on MacOS via homebrew Or on Linux via your package manager.

  2. building pas2js

2.1 Under Linux/macOS type make all

This creates with a 64-bit fpc the executable "bin/x86_64-linux/pas2js" and a basic config file "bin/x86_64-linux/pas2js.cfg".

2.2 Under Windows type

Make sure that you use the make.exe from fpc, not from Delphi by setting the "PATH": For example if you installed the 32-bit version of fpc in C:\YourPathOfFPC\3.0.4

set PATH=C:\YourPathOfFPC\3.0.4\bin\i386-win32;%PATH%

If you installed the 64-bit version of fpc in C:\YourPathOfFPC\3.0.4 use

set PATH=C:\YourPathOfFPC\3.0.4\bin\x86-64-win64;%PATH%

Then compile make all

If you see "Error makefile ... Command syntax error" your "set PATH" was not correct.

When "make all" finished it created with a 32-bit fpc the executable "bin/i386-win32/pas2js.exe" and a basic config file "bin/i386-win32/pas2js.cfg".

Configuration

pas2js requires unit search paths (-Fu) in order to find its rtl units and rtl.js. Building and installing should have created a default pas2js.cfg containing those parameters.
