Allow specifying the width of the tall window in the Tall layout as a percentage of available space
Also remove the --window-layout option as it was redundant. Same effect can be achieved using -o enabled_layouts=some_layout,*

@ -343,6 +343,17 @@ You can switch between layouts using the {sc_next_layout} key combination. You c
|
||||
also create shortcuts to select particular layouts, and choose which layouts
|
||||
you want to enable/disable, see link:kitty/kitty.conf[kitty.conf] for examples.
|
||||
|
||||
Some layouts take options to control their behavior. For example, the `fat` and `tall`
|
||||
layouts accept the `bias` option to control how the available space is split up. To specify the
|
||||
option, in kitty.conf use:
|
||||
|
||||
```
|
||||
enabled_layouts tall:bias=70
|
||||
```
|
||||
|
||||
this will make the tall window occupy `70%` of available width. `bias` can be
|
||||
any number between 10 and 90.
|
||||
|
||||
Writing a new layout only requires about fifty lines of code, so if there is
|
||||
some layout you want, take a look at link:kitty/layout.py[layout.py] and submit
|
||||
a pull request!
