Public

A C library for building parsers, by defining non-left-recursive rules in a context-free grammar and composing them with combinators, and operating on the resulting abstract syntax trees.

AI Summary

Spl is a lightweight C library for defining and composing parsing rules to analyze text against custom grammars and build structured trees from matches.

How It Works

1
🔍 Find Spl

You stumble upon Spl while searching for a simple way to teach your program to understand patterns in text, like custom file formats.

2
📁 Add to your project

You copy a few simple files into your own program folder so it's ready to use.

3
📝 Describe text patterns

You write easy rules saying what characters or sequences to expect, like numbers or quotes.

4
✨ Build your grammar

You mix those rules together to handle full structures, like lists or maps, feeling the power as it grows.

5
📄 Test with real text

You give it some sample text, and it checks if it fits your rules perfectly.

6
🌳 Get the structure tree

It hands you a clear map of the text's parts, ready to explore and use.

🎉 Program reads anything

Now your program effortlessly breaks down any matching text into usable pieces, saving you tons of time!

What is spl?

Spl is a C library for crafting parsers from context-free grammars using combinators like sequences, choices, repeats, and optionals, all non-left-recursive to avoid common pitfalls. Drop the files into any C project via github library download, define rules for your input format, and parse strings into abstract syntax trees you can collapse, simplify, or wipe for clean traversal. It solves the drudgery of manual parser code, delivering structured output fast – includes a full JSON parser demo as proof.

Why is it gaining traction?

Zero deps and copy-paste integration beat heavyweight alternatives like ANTLR or Bison for C, where github library api needs stay lean. The hook: build complex grammars intuitively, get ASTs mirroring your rules, and post-process them easily – JSON example handles numbers, strings, arrays, objects out of the box. Devs try it for quick prototypes in constrained envs, unlike verbose tools.

Who should use this?

Embedded C devs parsing configs or protocols on resource-tight hardware, echoing github library arduino simplicity. Low-level systems programmers building domain-specific languages or data loaders. Suited for library building design in C projects needing lightweight parsing, like config files or custom formats in games or tools.

Verdict

At 10 stars and 1.0% credibility score, spl is early-stage with strong README docs and examples but admitted memory issues and minimal tests – not production-ready yet. Grab it from the github library repository for experiments if C parsing fits; contribute to mature it.
