raylib parser

This parser scans raylib.h to get information about defines, structs, enums and functions. All data is separated into parts, usually as strings. The following types are used for data:

  • struct DefineInfo
  • struct FunctionInfo
  • struct StructInfo
  • struct EnumInfo

Check raylib_parser.c for details about those structs.

USAGE:

    > raylib_parser [--help] [--input <filename.h>] [--output <filename.ext>] [--format <type>]

OPTIONS:

    -h, --help                      : Show tool version and command line usage help

    -i, --input <filename.h>        : Define input header file to parse.
                                      NOTE: If not specified, defaults to: raylib.h

    -o, --output <filename.ext>     : Define output file and format.
                                      Supported extensions: .txt, .json, .xml, .h
                                      NOTE: If not specified, defaults to: raylib_api.txt

    -f, --format <type>             : Define output format for parser data.
                                      Supported types: DEFAULT, JSON, XML, LUA

    -d, --define <DEF>              : Define functions specifiers (i.e. RLAPI for raylib.h, RMDEF for raymath.h, etc.)
                                      NOTE: If no specifier defined, defaults to: RLAPI

    -t, --truncate <after>          : Define string to truncate input after (i.e. "RLGL IMPLEMENTATION" for rlgl.h)
                                      NOTE: If not specified, the full input file is parsed.


EXAMPLES:

    > raylib_parser --input raylib.h --output api.json
        Process <raylib.h> to generate <api.json>

    > raylib_parser --output raylib_data.info --format XML
        Process <raylib.h> to generate <raylib_data.info> as XML text data

    > raylib_parser --input raymath.h --output raymath_data.info --format XML
        Process <raymath.h> to generate <raymath_data.info> as XML text data

Constraints

This parser is specifically designed to work with raylib.h, so, it has some constraints:

  • Functions are expected as a single line with the following structure:
   <retType> <name>(<paramType[0]> <paramName[0]>, <paramType[1]> <paramName[1]>);  <desc>

Be careful with functions broken into several lines, it breaks the process!

  • Structures are expected as several lines with the following form:
   <desc>
   typedef struct <name> {
       <fieldType[0]> <fieldName[0]>;  <fieldDesc[0]>
       <fieldType[1]> <fieldName[1]>;  <fieldDesc[1]>
       <fieldType[2]> <fieldName[2]>;  <fieldDesc[2]>
   } <name>;
  • Enums are expected as several lines with the following form:
   <desc>
   typedef enum {
       <valueName[0]> = <valueInteger[0]>, <valueDesc[0]>
       <valueName[1]>,
       <valueName[2]>, <valueDesc[2]>
       <valueName[3]>  <valueDesc[3]>
   } <name>;

NOTE: For enums, multiple options are supported:

  • If value is not provided, (<valueInteger[i -1]> + 1) is assigned
  • Value description can be provided or not

Additional notes

This parser could work with other C header files if mentioned constraints are followed.

This parser does not require <string.h> library, all data is parsed directly from char buffers.
