PL-Compiler

Simple programming language's compiler for .NET Core platform which uses Lex, Yacc and Roslyn

Why are a few projects in this solution?

The main project is MyCompiler, it is a project of my language's compiler. Roslyn is the submodule which contains modified Microsoft.CodeAnalysis.CSharp project.

How to clone the solution?

Long-time option (because of too many commits in submodule's history)

$ git clone https://github.com/nikitaodnorob/pl-compiler.git --recursive

Fast option (doesn't load all history)

$ git clone https://github.com/nikitaodnorob/pl-compiler.git --depth 1
$ cd pl-compiler
$ git submodule update --init --depth 1 Roslyn

How to build the MyCompiler project?

1. Open solution Roslyn/Compilers.sln and build project Microsoft.CodeAnalysis.CSharp
2. If you need, change file MyCompiler/config/lex.lex (it is lexer's file) or MyCompiler/config/yacc.y (it is Yacc's file with language's grammar)
3. Run MyCompiler/config/generate.bat for generating code of lexer and parser
4. It will generate files Lexer.cs and Parser.cs in folder MyCompiler/GeneratedParser/. These files have to be recompiled after any change of files lex.lex or yacc.y
5. Generated files has already been added to project MyCompiler. The project is ready for build!
6. Build project MyCompiler

How to use the MyCompiler project

The MyCompiler.exe is located in MyCompiler/bin/Debug/netcoreapp3.1

Some language examples are located in MyCompiler/examples

$ cd MyCompiler/bin/Debug/netcoreapp3.1/
$ MyCompiler.exe ../../../examples/tuples.mylang tuples.exe

$ dotnet tuples.exe

System requirements

• OS Windows (for gppg launching; later the compiled parser will be uploaded to repository)
• Installed .NET Core version 3.1 or above
