Code editor component for PyQt5

Component has been created for Enki editor as replacement for QScintilla

API documentation


  • Syntax highlighting for 196 languages
  • Smart indentation for many languages
  • Line numbers
  • Bookmarks
  • Advanced edit operations
  • Matching braces highlighting
  • Autocompletion based on document content
  • Marking too long lines with red line
  • Rectangular selection and copy-paste
  • Vim mode

Building and installation on Linux

Qutepart depends on:

  • Python 3
  • PyQt5
  • pcre

Versions up to 2.2.3 used to work on Python 2 and PyQt4.

1. Install pcre and development files

On Debian, Ubuntu and other Linuxes install package libpcreX-dev, where X is available in your distribution pcre version. For other OSes - see instructions on pcre website

2. Install Python development files

On Debian, Ubuntu and other Linuxes install package python3-dev, on other systems - see Python website

3. Install C compiler

It will probably be gcc

4. Build and install the package

python3 install

Building and installation on Windows

  • Download and install the CMake binary. Tested with 2.8.12.
  • Download and install Microsoft Visual Studio Express Edition 2010 (or the full version).
  • Create a root directory and place the following as subdirectories in it:

Make pcre

cd <pcre-8.37 source>
mkdir build
cd build
cmake --build . --config Release

Build/install Python modules

cd qutepart
python3 build_ext --include-dir=../pcre-8.37/build --lib-dir=../pcre-8.37/build/Release
python3 -m pip install -e .

Tests status

Qutepart contains a lot of tests. See tests/ directory. This tests are very useful to verify correctness of highlighting, indentation, Vim mode, etc. The tests often fail on CI because of hard-to-track PyQt bugs. Many issues were workarounded, but new issues appear on new OSes and software envinronments. If we try to run tests on CI, more time are spent on finding workarounds than saved by tests. It is not recommended to run the tests automatically now, hovewer the tests still live in the repository for manual execution by developers.

Qutepart and Katepart

Kate and Katepart (an editor component) is really cool software. The Kate authors and community have created, probably, the biggest set of highlighters and indenters for programming languages.

  • Qutepart uses Kate syntax highlighters (XML files)
  • Qutepart contains a port from Javascript to Python of Kate indenters (12% of the code base in version 1.0.0)
  • Qutepart doesn't contain Katepart code.

Nothing is wrong with Katepart. Qutepart has been created to enable reusing highlighters and indenters in projects where a KDE dependency is not acceptable.
