map to function to run multiple actions i.e. zen mode

[jimcornmell]

I'm interested to create a keyboard mapping to go to a zen mode, which makes sets full screen and increases the font size. Something like the following in the kitty config file. Is this possible?

 map kitty_mod+z  toggle_zenmode

 function toggle_zenmode
       if inzenmode
             change_font_size all -4.0
             inzenmode = false
       else
             change_font_size all +4.0
             inzenmode = true
       endif

       toggle_fullscreen
endfunction

See the very first example here: https://sw.kovidgoyal.net/kitty/kittens/custom.html

This seems to work:

def main(args):
     pass


from kittens.tui.handler import result_handler


@result_handler(no_ui=True)
def handle_result(args, answer, target_window_id, boss):
    boss.change_font_size("all", "+", 4.0)
    boss.toggle_fullscreen()

One last question (promise) How can you tell you are in fullscreen mode? I can see in the C there is "is_window_fullscreen" but cannot see the equivalent in the python API.

There isn't. Fullscreen can be triggerred in many ways, from outside of kitty as well. And there are different types of fullscreen on different platforms.

Hi, In that case whats the easiest way to persist a value between instantiations of the kitten without resorting to databases or system variables?

The UI part of the kitten is invoked in the same process, just use a global variable.

Does not appear to work I have this in kitty.conf:

map kitty_mod+z kitten zenmode.py

And this in zenmode.py:

from kittens.tui.handler import result_handler

def main(args):
    pass

@result_handler(no_ui=True)
def handle_result(args, answer, target_window_id, boss):
    global inZenMode

    try:
        inZenMode
    except:
        inZenMode = False

    if inZenMode:
        boss.change_font_size("all", "-", 5.0)
        inZenMode = False
    else:
        boss.change_font_size("all", "+", 5.0)
        inZenMode = True

    boss.toggle_fullscreen()

You need an actual inZenMode outside the function. the global keyword doesnt make a variable global only declares that the local variable does not shadow the global one.

Hi, Sorry I'm not a python programmer, but that does not appear to work either:

from kittens.tui.handler import result_handler

def main(args):
    pass

try:
    inZenMode
except:
    inZenMode = False

@result_handler(no_ui=True)
def handle_result(args, answer, target_window_id, boss):
    global inZenMode

    try:
        inZenMode
    except:
        inZenMode = False

    if inZenMode:
        boss.change_font_size("all", "-", 5.0)
        inZenMode = False
    else:
        boss.change_font_size("all", "+", 5.0)
        inZenMode = True

    boss.toggle_fullscreen()

[kovidgoyal]

```py from kittens.tui.handler import result_handler def main(args): pass @result_handler(no_ui=True) def handle_result(args, answer, target_window_id, boss): in_zen_mode = getattr(boss, 'in_zen_mode', False) boss.change_font_size("all", "-" if in_zen_mode else '+', 5.0) boss.toggle_fullscreen() boss.in_zen_mode = not in_zen_mode ```

Perfect! Many thanks, I've learnt a lot.
