How to install console leo w/o installing pyqt?

[gar]

I have a very ancient notebook, it is still 32bits. surprisingly recent lubuntus run fine there.

I use it time after time but! I cannot use it with .leo files cause it is absolutely impossible to install Leo on 32bit systems since pyqt is required and pyqt for itself supports only 64bit linuxes.

I'd love to have a chance to use console gui, but cannot imagine how to do it.

Clone from git, install all deps manually, ignore failed pyqt? Is it possible to ask pip install all ignoring failed packages?

Just don't install pyqt at all.

I was playing with the web app version of flexx a while back and I think I only installed these pip packages:

pip install docutils nbformat pylint pypandoc sphinx semantic_version flexx

and then ran leo from the git checkout with --gui=browser.

You should be able to replace flexx above with whatever pip package provides the curses functionality.

I haven't found a way of instructing pip to skip failures.

One option would be to comment out the lines in setup.py:user_requires that involve pyqt, and then `pip install --editable path/to/leo-code` as normal.

 

Just the 1st two I think:

user_requires = [
    #'PyQt5 >= 5.12, < 5.13',  # v5.12+ to close #1217
    #'PyQtWebEngine < 5.13',  # #1202 QtWebKit needs to be installed separately starting Qt 5.6
    'asttokens', # abstract syntax tree text parsing
    'docutils',  # used by Sphinx, rST plugin
    'flexx',  # for LeoWapp browser gui
    'meta',  # for livecode.py plugin, which is enabled by default
    'nbformat',  # for Jupyter notebook integration
    'pylint', 'pyflakes', 'black',  # coding syntax standards
    'setupext-janitor >= 1.1',  # extend `setup.py clean` #1055,#1255
    'pyshortcuts >= 1.7',  # desktop integration (#1243)
    'sphinx',  # rST plugin
    'windows-curses; platform_system=="Windows"',  # for console mode on Windows
    ]

2nd option would be to just run `python launchLeo.py --gui=console` iteratively and manually pip install each "failed to import xxxx" module until it works.

Thanks!

I suspected that it would be that strange :-)

BTW if there be widely used console gui - it could be great to have a dedicated package for it, so that leo could consist of several packages: core, console, qt, probably vim and emacs...

It might be as simple as a req-console.txt, req-flexx.txt. etc. that can be installed with `pip install --requirements req-console.txt`. Share the modules list if/when you figure it out and we'll save it somehwere.
