This directory contains a copy of the JavaScript grammar in grammars-v4 that has been set up with trgen drivers. Trgen is part of the Trash toolkit for grammars. The driver code here is generated for the Linux OS or MSYS2 in the Windows OS.
The code contained here can be built using "make" or "dotnet build". You will need to set yourself up with the appropriate environment for the build, i.e., download and install dotnet for building and running C#, download the Antlr4 tool JAR file and installing Java or Node.js for the other targets.
For any other targets not contained here, use trgen to generate the driver.
