PeppaPEG VS pl0c

- Having a PEG parser in ANSI C can benefit whoever is developing a parser, as adding C bindings for other programming languages are not too difficult.

And after SIX months' development, my project is now kinda feature complete. It's named Peppa PEG and you can find it here: .

I have learned quite a lot during the journey of creating it, such as gdb, valgrind, cmake, etc. And I wouldn't make it to the end without learning from some awesome projects, such as pest.rs, cJSON, etc.

To give you a glance how the library is used, here are some examples:

- Write an INI Parser using Peppa PEG: [ini.h](https://github.com/soasme/PeppaPEG/blob/main/examples/ini.h).

> Some compilers tokenize while parsing, but for a different reason: it's faster and uses less memory to generate the AST

And some don't even generate an AST. :) Just read in and emit or interpret.

Single-pass compiler tutorial

Let's Write a Compiler

I don’t think there will be an AST. https://briancallahan.net/blog/20210814.html: “We will be writing a single-pass compiler for a simple language and immediately output our final output code as soon as our compiler has enough information to do so”

That “as soon as” implies code will be generated before the entire program has been parsed.

Also, for me single-pass implies “no AST”, as you would need at least one pass to construct one, and iterating over an AST counts as another pass for me.
