Rust module for parsing C code. Port of Haskell'slanguage-c, semi-automatically translated usingCorollary.

This port is a work in progress. A lot of work remains to parse anything but very simple C files; while most source code has been translated from Haskell, errors in translation prevent it from matching language-c's functionality yet. Here are the next steps for achieving parity, in order:

1. Building up an equivalent test bed to language-c's, then automatically cross-check
2. Fix errors in the ported code to support those test cases
3. Converting portions of the code into Rust idioms without breaking tests
4. Figure out a porting story for the alex/happy generated parser output

parser-c requires nightly (for now). Seetests/ for some working examples, or try this example:

externcrate parser_c;use parser_c::parse;constINPUT:&'staticstr =r#"int main() {    printf("hello world!\n");    return 0;}"#;fnmain(){matchparse(INPUT,"simple.c"){Err(err) =>{panic!("error: {}", err);}Ok(ast) =>{println!("success: {:#?}", ast);}}}

Result is:

success: Right(    CTranslationUnit(        [            CFDefExt(                CFunctionDef(                    [                        CTypeSpec(                            CIntType(                                ..                            )                        )                    ],                    CDeclarator(                        Some(                            Ident(                                "main",                                124382170,                                ..                            )                        ),                        ...

Clone this crate:

git clone https://github.com/tcr/parser-c --init --recursive

Hacking on the lexer and parser requires to build and run the Haskelldependencies using:

./regen.sh

The test suite is being ported at the moment. It is in a separate crate,because it requires a build script with prerequisites, so to run it, usethis script:

./test.sh
