parceqt

Small Python library to use parce with Qt's QTextDocument.

This module depends on parce (https://parce.info/) and PyQt(https://riverbankcomputing.com/software/pyqt)

Homepage: https://github.com/wbsoft/parceqt

Download: https://pypi.org/project/parceqt

Documentation: https://parce.info/parceqt

Example:

from PyQt5.QtWidgets import QApplication, QTextEdit
from PyQt5.QtGui import QTextDocument

app = QApplication([])
doc = QTextDocument()
e = QTextEdit()
e.setDocument(doc)
e.resize(600, 400)
e.show()

import parceqt
from parce.lang.xml import Xml

parceqt.set_root_lexicon(doc, Xml.root)
parceqt.highlight(doc)
parceqt.adjust_widget(e)    # adjust widgets font and base colors

Now the text in the document is automatically highlighted using the specified root lexicon; the highlighting is updated as the user modifies the text.
