@thecoolwinter curious about when do changes made on the CodeEditTextView get merged and released in the CodeEdit app themselves. do you guys have some sort of fixed schedule, or do you do it more by feel?

[thecoolwinter]

We release whatever the latest version of CESE and CETV are with a CodeEdit release. We don't have a specific release schedule, but I think it will be soon considering some recent changes.

nice. thanks!

[thecoolwinter]

@godbout It's been released! https://github.com/CodeEditApp/CodeEdit/releases/tag/v0.3.6 let me know if it works with kindaVim or if it's still got some bugs.

@thecoolwinter kV still can't make use of CodeEdit's TextView/TextArea. will review and let you know if there's anything that can be done. thanks!

@thecoolwinter ok, interesting. so all the AX data needed is there. thanks for that! but somehow the CodeEditTextView doesn't refresh/update when AX data is pushed to it. i push the caret location and the selected length (through the kAXSelectedTextRangeAttribute attribute), but in the CETV the caret is just gone lol. see below:

1. here i enter kV Normal Mode with the caret location being after the second e on line 25. what's supposed to happen is the second e gets selected (so it looks like a block cursor on e). then i press ciw which selects LeftRightSearch, deletes it, and makes kV go back to Insert Mode, which means we're not back into normal macOS. at that time LeftRightSearch is supposedly removed, and the blinking typing caret should be located after public struct . so it DOES NOT LOOK LIKE IT but behind the scene everything is happening normally lol, it's just not SHOWN in CETV. the proof is that i type this all i've described above, and everything appears where it should appear. caret at the right position, right selection was deleted, etc. it just didn't SHOW in CETV. after that i undo by going back to kV Normal Mode and pressing u to undo. we can see the changes getting undone.

2. here i use kV Visual Mode to select a few lines. you'll see the line numbers getting highlighted, but again CETV doesn't reflect the selection. then i delete with d. in that case the CETV changes get reflected. i do a bit of undo, delete again, and then use cc to delete the public enum line and switch to Insert Mode (normal macOS). then i can start typing. as with the first video, it does work. everything is at the proper place, BUT the CETV somehow doesn't refresh the changes.
