Is it possible to configure how the splits layout splits its windows in a session file?

[unikitty37]

Is it possible to configure the splits layout from a session file? I have this session as work.session

new_os_window
layout splits
os_window_state maximized
os_window_class work_files
cd ~/work
launch --title "Docker" lazydocker
launch --title "Git" lazygit
launch --title "Console" rails c
launch --title "Shell" zsh

but when I launch kitty --session=work.session Kitty makes its own decision on how to lay out the splits, which isn't the way I want — meaning I have to manually rearrange them before I can start. This is what I'm looking for:

I can set the bias to be horizontal or vertical, but I don't think I can change it in between launch commands, can I?

(Note that the grid layout won't work as the two panes on the right aren't the same height as each other :)

Use launch --location=vsplit/hsplit to create your splits and at the end have

launch --allow-remote-control kitten @ resize-window whatever

to resize the last focused window as much as you like.

Thanks!

yuyhyI'm not sure of quite how to do the grouping on this, TBH. I want to split the main window horizontally, then split each half vertically, but this

launch --title "Docker" lazydocker
launch --title "Git" --location=hsplit lazygit
launch --title "Console" --location=after rails c
launch --title "Shell" --location=hsplit zsh

splits it like this

+-------------+
|             |
|             |
|             |
|             |
|             |
|             |
+------+------+
|      |      |
|      |      |
|      |      |
+      +------+
|      |      |
|      |      |
+------+------+

I don't suppose there's a way to manually set the splits how I like them, then run a command to get kitty to output the required commands to regenerate that split, is there?

``` layout splits launch --var first-window= launch --location=vsplit launch --location=hsplit resize_window shorter 5 launch --type=background --allow-remote-control sh -c 'kitten @ focus-window --match var:first-window; kitten @ launch --location=hsplit --dont-take-focus' ```

[unikitty37]

Thanks again — I ended up with this, which does what I wanted. (The --match id:1 seemed to be matching the default window rather than the new one opened in the session, so I set an explicit title to match against.)

new_os_window --title "Work"
layout splits
os_window_state maximized
os_window_class work
cd ~/work
launch --title "Docker" lazydocker
launch --title "Console" --location=vsplit zsh
launch --title "Shell" --location=hsplit zsh
resize_window shorter 4
launch --allow-remote-control sh -c 'kitten @ focus-window --match 'title:^Work'; kitten @ launch --title "Git" --location=hsplit --dont-take-focus lazygit'

You dont need to use title you can use user variables, see my edited reply above.
