set_tab_title not working in 0.26.0

[djensenius]

Describe the bug set_tab_title is not working

To Reproduce I have shortcuts to quickly title tabs: For example:

map kitty_mod+shift+c set_tab_title 

This fails as following:

Failed to parse action

set_tab_title HELLO
'Unknown action: set_tab_title'

Press e to see detailed traceback or any other key to exit
Traceback (most recent call last):
  File "lib/python3.9/kitty/boss.py", line 1304, in combine
  File "lib/python3.9/kitty/options/utils.py", line 945, in resolve_aliases
  File "lib/python3.9/kitty/options/utils.py", line 995, in resolve_aliases_and_parse_actions
  File "lib/python3.9/kitty/options/utils.py", line 921, in parse_key_action
KeyError: 'Unknown action: set_tab_title'

Press Enter or Esc to exit

Further, if I try to interactively set the title, it fails silently.

Screenshots If applicable, add screenshots to help explain your problem.

Additional context

[kovidgoyal]

set_tab_title doesnt take arguments, it's meant for interactive usage only.

map f1 set_tab_title

will work fine. https://sw.kovidgoyal.net/kitty/actions/#action-set_tab_title

[kovidgoyal]

And here I have added support for supplying arguments to this action: https://github.com/kovidgoyal/kitty/commit/5b28aed0b116621c7dad5e0b3fe60ef13399fb4c

[djensenius]

Awesome!!! Thank you!

I'm still seeing it not change my tab title, but that could be another issue in my config.

You have some custom tab bar I am guessing, first make sure it works with the default tab bar

[sdemura]

I am seeing this issue too. Trying to rename a tab results in a no-op. (The tittle doesn't change)

Then I need a way to reproduce. Bisect your kitty.conf and post a minimal version that reproduces.

[kovidgoyal]

I tried it with your full config and it works for me, pressing super+shift+i and typing in a new tab title, the title in the tab bar changes, as expected.

Here is one without custom tabs. It does not rename the tab, just keeps the path as the title. I'm on macOS.

[kovidgoyal]

ah, macOS. You are probably suffering from a side-effect of #5439.

TO confirm start kitty from another terminal as

LANG=en_US.UTF-8 /Applications/kitty.app/Contents/MacOS/kitty

and it should work

[djensenius]

Aha! That did indeed work!
