CMake Parser for Rust

cmake-parser is a Rust library that provides a set of tools for parsing CMake files and working with the data they contain. The library includes a parser for reading CMake files, as well as several structs and enums for representing the data defined in CMake files.

CMake version: v3.26

CMake Language specification:

https://cmake.org/cmake/help/v3.26/manual/cmake-language.7.html

Features

The cmake-parser library provides the following features:

• Parsing of CMakeLists.txt files: The library includes a parser for reading CMakeLists.txt files and extracting the data defined in them.
• Error handling: The library provides a set of error types for handling errors that may occur during parsing and processing of CMake files.

Usage

Add dependency to Cargo.toml:

[dependencies]
cmake-parser = "0.1"

Example src/main.rs:

use cmake_parser::{parse_cmakelists, Doc};

let cmakelists = br#"""
add_custom_command(
  TARGET myExe POST_BUILD
  COMMAND someHasher -i "$<TARGET_FILE:myExe>"
                      -o "$<TARGET_FILE:myExe>.hash"
  VERBATIM)
"""#;

let cmakelists = parse_cmakelists(cmakelists).expect("valid CMakeLists.txt");
let doc = Doc::from(cmakelists);
let commands = doc.commands().expect("valid CMake commands");
dbg!(commands);
