Crate mpc

This crate provides simple bindings for orangeduck’s mpc library. This is still a work in progress and contains a modified version of mpc and some temporary glue code

Modules

ast

Contains an AST type to which mpc_ast_t is mapped

colors

Contains consts for ANSI color escape sequences

glue

Contains the rust-side of glue code. The main purpose of the code is to avoid having to interface with a C union in Rust. The main offender is mpc_result_t

macros

Contains some nice macros to help with needed FFI and parser creation The str_c! and c_str! macros exist because of ownership issues

mpc_c

Contains mpc function definitions

mpc_c_types

Contains a Rust representation of mpc’s underlying C types that are exposed in the mpc.h header

Macros

c_str

Convert a rustic string (whether &str or String) to C’s const char*

dfs

Dereference pointer and convert struct member mem to String

dfu

Dereference pointer and convert struct member mem to usize

g_string

simulate C’s compile time string literal concatenation to allow copy-pasta of mpc grammars written in C without any hassle

parser

Create a mpc_parser_t using mpca_lang grammars

run_parser

Runs a parser prepared with parser!

str_c

Convert a C’s const char* to a rustic String

trace

print! for lazy people - no format, args are thrown in delimited with spaces

traceln

println! for lazy people - no format, args are thrown in delimited with spaces also throw in a newline
