Detailed Description

Modular command-line argument parser.

Todo

More descriptive errors, help and version options, use virtual methods for customization points, implement signals for events (probably), process(..) top-level method for handling exiting upon failure, version, or help.

Function Documentation

GblCmdParser_type()

GblType GblCmdParser_type

(

void

)

Returns the GblType UUID associated with GblCmdParser.

GblCmdParser_create()

GblCmdParser * GblCmdParser_create

(

void

)

Creates a GblCmdParser object, initializes it, and returns a pointer to it.

GblCmdParser_unref()

GblRefCount GblCmdParser_unref

(

GblCmdParser *

pSelf

)

Unreferences a GblCmdParser, destroying it if it's the last one, returning the remaining reference count.

GblCmdParser_executable()

GblStringRef * GblCmdParser_executable

(

const GblCmdParser *

pSelf

)

After parsing, returns a GblStringRef to the name of the current executable (first positional argument)

GblCmdParser_unknownOptions()

const GblStringList * GblCmdParser_unknownOptions

(

const GblCmdParser *

pSelf

)

After parsing, retuns a GblStringList to the internally maintained list of unknown command-line options.

GblCmdParser_parse()

GBL_RESULT GblCmdParser_parse	(	GblCmdParser *	pSelf,
		GblStringList *	pArgs )

Parses the list of arguments given by pArgs, populating internal structures, and returning the result.
