The work module#

The Worker class, inheriting from parce’s Worker class.

class Worker(qtextdocument, treebuilder=None, transformer=None)[source]#

A Worker that uses Qt signals instead of callbacks.

This Worker is attachted to a QTextDocument, and automatically updates the tokens (and optionally the transformed result) when the document changes.

started#: Qt signal emitted with no arguments when start_build() is called.

tree_updated#: Qt signal emitted with two arguments (start, end) when the tree has been updated.

tree_finished#: Qt signal emitted with no arguments just after tree_updated has been emitted.

transform_finished#: Qt signal emitted with no arguments when the transformation has been finished.

debugging = False#: set debugging to True to print some info to the console while running

slot_contents_change(start, removed, added)[source]#: Called after modification of the text, retokenizes the modified part.

run_process()[source]#: Reimplemented to run parts of the process in a Qt Thread.

wait_build()[source]#

Immediately returns if there is no build job active.

wait_transform()[source]#

Wait for the transform job to be completed.

Immediately returns if there is no transform job active.

finish_build()[source]#: Reimplemented to emit the tree_updated and tree_finished signals.

finish_transform()[source]#: Reimplemented to emit the transform_finished signal.
