## raylib parser

This parser scans [`raylib.h`](../src/raylib.h) to get information about `structs`, `enums` and `functions`.
All data is separated into parts, usually as strings. The following types are used for data:

 - `struct FunctionInfo`
 - `struct StructInfo`
 - `struct EnumInfo`
 
Check `raylib_parser.c` for details about those structs.

## Command Line Arguments

The parser can take a few options...

- `--help` Displays help information about the parser
- `--json` Outputs the header information in JSON format

## 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.
