function prod_janet_execute

Execute a production in a Janet VM.

STATIC_INLINE char * prod_janet_execute (
    const void * config,
    const char * script
)

Create a Janet VM with an overloaded print statement. Pass the current production script to the Janet VM and run the script.

Parameters:

config The current production configuration. Must be cast to the Janet type.
script The script to execute one of replacement or terminal.

Returns:

A pointer to the output string. NULL on error.

function prod_janet_pdglcout

Parse a print calling back from Janet to c.

STATIC_INLINE Janet prod_janet_pdglcout (
    int32_t argc,
    Janet * argv
)

From inside a Janet VM call back into the PDGL c code. Add the first argument to the output string buffer of the config pointed to by the second argument.

Parameters:

argc A count of arguments.
argv A list of void pointers to argument.

Returns:

Pass back to the Janet VM a nil value.

function prod_janet_resolve

The resolve function for the Janet production type.

const char * prod_janet_resolve (
    const void * config
)

Starts a Janet VM and executes the configured resolution script.

Parameters:

config A configuration of a production.

Returns:

A pointer to the output of the resolution.

function prod_janet_terminate

The resolve function for the Janet production type.

const char * prod_janet_terminate (
    const void * config
)

Starts a Janet VM and executes the configured terminal script.

Parameters:

config A configuration of a production.

Returns:

A pointer to the output of the resolution.
