Compiler example

[NeoCortex97]

Hi everyone,
I want to build some tool, that transforms a simple project definition language into a set of scripts to setup the project, install tooling, etc. And I want to generate a buildsystem and package manager config for the project.

That far on my dreams.
Normally I would build the parser part and stuff in C/C++ and wrap it so I can use it with python. I already found guides to do that, but fould lark before I tried.

Lark looks worlds more compelling to me, so I would gladly take a hit at using ist. But I failed to find an example that shows a basic way to build a Compiler or transpiler, so I wanted to ask around if somebody here already built a compiler that I can look at. And if you would be willing to discuss with me, how I could possibly build it.

So you know all relevant things, I would talk some more about the things that can belong to lark.

I want to be able to start it with a script file and it should interpret it. I want the option to drop into a repl from inside the script, so I would need to replicate some state between repl and compiler.

I want to start the repl from the get go and would like to keep a history and on close analyze the history and generate a script from it. Maybe run some analysis on the history so the generated code does make sense. The generation part is not of interest here.

And I wanted to ask if you know a guide or book how to structure a language grammar so it is easy to interpret and write.

Thanks for your time and patience with me. I'm a cs student that didn't take an compiler building, course yet, but is royally fedup with cmake syntax...

Got something to add already:
How would you guys implement imports?

[erezsh]

I wrote a compiler/interpreter with Lark: https://github.com/erezsh/Preql/

It also implements imports.

You can also look at https://craftinginterpreters.com/

I haven't checked, buy EQL might also fit the bill, since it uses Lark: https://github.com/endgameinc/eql
