copy

parseContextCopy

Arguments

:: (HasCallStack, MonadIO m)

=> ParseContext

context: a ParseContext

-> m (Maybe ParseContext)

Returns: A copied ParseContext

Copies the context.

Since: 1.12.1

free

parseContextFree

Arguments

:: (HasCallStack, MonadIO m)

=> ParseContext

context: a ParseContext

-> m ()

Frees a parse context previously allocated with parseContextNew.

getMissingElements

parseContextGetMissingElements

Arguments

:: (HasCallStack, MonadIO m)

=> ParseContext

context: a ParseContext

-> m (Maybe [Text])

Returns: a Nothing-terminated array of element factory name strings of missing elements. Free with strfreev when no longer needed.

Retrieve missing elements from a previous run of parseLaunchFull or parseLaunchvFull. Will only return results if an error code of ParseErrorNoSuchElement was returned.

new

parseContextNew

Arguments

:: (HasCallStack, MonadIO m)

=> m (Maybe ParseContext)

Returns: a newly-allocated parse context. Free with parseContextFree when no longer needed.

Allocates a parse context for use with parseLaunchFull or parseLaunchvFull.
