Description Hannes 2024-01-12 09:45:37 UTC

SUMMARY

Ligatures that are on-by-default seem to work, but I can find no way to turn on optional Ligatures like those provided by the Monaspace fonts: https://github.com/githubnext/monaspace


STEPS TO REPRODUCE
1. Download Monaspace fonts and install
2. Select them in Kate

OBSERVED RESULT

Optional ligatures are not available.

EXPECTED RESULT

There should be GUI element that allows turning ligatures on/off and selecting optional ligatures. This code could be shared with other KDE components that do font selection.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Kubuntu 23.10
KDE Frameworks Version:   5.110.0
Qt Version: 5.15.10

FontChoose: Allow setting font features when selecting font

Atm this setting can't work without support from the application because
QFont::toString() doesn't include the feature tags and we (Kconfig) uses
QFont::toString() to save a font

Comment 5 Christoph Cullmann 2024-08-22 21:05:58 UTC

We still need to fix the config saving.

Comment 6 Christoph Cullmann 2024-08-24 16:24:48 UTC

For KTextEditor that works, we still need a generic solution for KConfig, not sure how to do that without breaking compatibility.

Comment 7 Christoph Cullmann 2024-08-24 16:25:43 UTC

We would need https://invent.kde.org/frameworks/ktexteditor/-/merge_requests/720 in generic to support the features of both free modern fonts like Inter or paid stuff like MonoLisa.
