Member Typedef Documentation

typedef const char*(* ucommon::Script::check_t)(Script *img, Script::header *scr, Script::line_t *line)

A type for compile-time command verification method invokation.

Definition at line 64 of file ccscript.h.

typedef event ucommon::Script::event_t

Convenience typedef to allow use of event name.

Definition at line 140 of file ccscript.h.

typedef struct ucommon::Script::keyword ucommon::Script::keyword_t

NAMESPACE_UCOMMON A structure to introduce new core commands to the runtime engine.

This is typically passed to assign as an array. Entries with no runtime method (method = NULL) are only processed at compile-time.

typedef struct ucommon::Script::line ucommon::Script::line_t

Basic compiled statement.

This is a linked list of statement lines, with an array of parsed statement arguments. An optional dsp resource mask value can be assigned by a check method on a per-line basis as well as at closure time for a script.

typedef bool(Script::interp::* ucommon::Script::method_t)(void)

A type for runtime script method invokation.

Definition at line 41 of file ccscript.h.

Member Function Documentation

void ucommon::Script::assign ( Script::keyword_t * keyword )

static

Assign new keywords from extensions and derived service.

Must be called before any use.

Parameters

list	of keywords to add to engine.

Definition at line 336 of file script.cpp.

Script * ucommon::Script::compile	(	Script *	merge,
		const char *	filename,
		Script *	config = `NULL`
	)

static

Compiled a file into an existing image.

A shared config script can be used that holds common definitions. Multiple script files can also be merged together into a final image.

Parameters

merge	with prior compiled script.
filename	to compile.
config	image of script with common definitions.

Returns: compiled script object if successful.

Definition at line 427 of file script.cpp.

		char *	item,
		unsigned	size
	)

static

unsigned ucommon::Script::count ( const char * list )

static

Definition at line 1187 of file script.cpp.

Script::keyword_t * ucommon::Script::find ( const char * id )

static

Find a keyword from internal command table.

This includes the core runtime engine keywords set through init() and any derived ones added through assign.

Parameters

id	of command to find.

Returns: keyword object for the command or NULL.
