Ever since doing the initial completion support in #phosh 's osk-stub I wanted to add a generic "unix pipe" like completer. phosh-osk-stub would feed the program preedit on stdin and read the completions from the program's stdout.
That is there now and with that and some more changes I can use @zachdecook 's #swipeGuess to do swipe like typing. To be clear: all the hard work is done by swipeGuess, phosh-osk-stub just piggy backs on it:
@baliceauxPelican @zachdecook The possibility for doing that has been available since some time, see https://gitlab.gnome.org/guidog/phosh-osk-stub/-/merge_requests/34 (using uim) or
https://gitlab.gnome.org/guidog/phosh-osk-stub/-/tree/wip/libvarnam (using varnam) - for other completers. Looking forward to someone looking into fcitx or ibus.
