gramatika VS gram_grep

I wrote a lexer generator. It's pretty limited and poorly architected tbh, but feel free to have a look: https://github.com/dannymcgee/gramatika

I'm a huge nerd for programming languages and rendering, and to that end I've been putting together a general-purpose parsing library inspired by syn and using that to power a language server for WGSL.

I'm probably in the minority on this one, but I really hate writing verbose, repetitive code, so I freaking love macros. I will frequently use a one-off macro just to make something like a dispatcher function easier to read by cutting down on all the pomp and circumstance. I'm also working on a small crate that makes heavy use of proc macros, which I've already gotten a ton of mileage out of since it allows me to spin up a serviceable lexer with just a few lines of code. A lot of people really dislike macros because the source is hard to read and they're onerous to debug. They're not wrong on either of those points.

There is also gram_grep[0]"Search text using a grammar, lexer, or straight regex. Chain searches for greater refinement."

See also parsertl-playground[1] for online edit/test grammars.

I'm building an online yacc/lex (LALR(1)) grammar editor/tester to help develop/debug/document grammars, the main repository is here https://github.com/mingodad/parsertl-playground and the online playground with several non trivial examples is here https://mingodad.github.io/parsertl-playground/playground/ .

Select a grammar/example from "Examples" select box and then click "Parse" to see a parser tree for the source in "Input source" editor.

It's based on https://github.com/BenHanson/gram_grep and https://github.com/BenHanson/lexertl14 .

Any feedback is welcome !

The grammars available so far (with varying state of correctness):

- Ada parser

Thanks for the tip, but I fear storing the result on the stack will be too much to ask for for big lexers (see https://github.com/BenHanson/gram_grep/blob/c64f8829661f11b38a55b42b37f5051c5eabfaa6/main.cpp#L2301 for example).
