Toggle-able pane ratios

[avidseeker]

I have this command that disables preview and re-adjusts pane ratios (collapsing the third one).

map <a-p> :set ratios 1:5; set preview!

This command is almost toggle-able except for the :set ratios part. Is there a way to check ratios so that pressing <a-p> again returns it to the starting pane ratios?

It is possible. Lf exposes a lot of states as variables. You can use lf_ratios to check current ratio.

You can try to do something like map P %printenv > ~/lfenv to log all available values you can use.

I use lf_ratios for dynamic resize of previously specified panes like this but behavior is a bit wonky:

cmd resize &{{
	IFS=':'
	read -a r <<< "$lf_ratios"
	[ -n $lf_user_pane ] && n=$lf_user_pane || n=${#r[@]}
	((r[$n-1]$1$1))
	[ ${r[$n-1]} -lt 1 ] && r=( "${r[@]:0:$n-1}" "${r[@]:$n}" )
	[ ${#r[@]} -eq 1 ] && lf -remote "send $id set nopreview"
	lf -remote "send $id set ratios ${r[*]}"
	[ ${#r[@]} -eq 2 ] && [ $1 == "+" ] && lf -remote "send $id set preview"
}}

This kind of use case is already mentioned in the wiki: https://github.com/gokcehan/lf/wiki/Tips#toggling-the-preview-column

Something like below should work:

map <a-p> &{{
    if [ "$lf_preview" = true ]; then
        lf -remote "send $id :set preview false; set ratios 1:5"
    else
        lf -remote "send $id :set preview true; set ratios 1:2:3"
    fi
}}
