handle env var globbing/splitting

[kojq]

From hyprwm/Hyprland/issues/5172, we should handle env var globbing/splitting.

[kojq]

Description:

We will use the bind = WIN, N, togglespecialworkspace, hi throughout this.

input:

workspace = special:hi, on-created-empty:foot -H echo $HOSTNAME $TERM

output:

arch linux

input:

workspace = special:hi, on-created-empty:foot -H echo $TERM$HOSTNAME

output:

linuxarch

input:

workspace = special:hi, on-created-empty:foot -H echo $TERMINAL

output:

linuxINAL

input:

workspace = special:hi, on-created-empty:foot -H echo $HOSTNAME$TERM

output:

Now, with definitions in config.

input:

$HI=hello
workspace = special:hi, on-created-empty:foot -H echo $HI

output:

hello

input:

$TERMINAL=foot
workspace = special:hi, on-created-empty:foot -H echo $TERMINAL

output:

foot

1. The problem are we facing in Nested/recursive variable expansion broke somewhere after v0.35.0 Hyprland#5172 is when we set a var to something that is or contains another hyprlang var, we now interpret global var (with globbing/splitting) having priority over a hyprlang var.

2. Feature request: include variable expansion in source command. #32 wants to pass this info into the source keyword without defining (error occurs)

# this is a comment: $HOSTNAME=laptop
source=~/.config/hypr/$HOSTNAME.conf

odd, these seem to work on my end.

[vaxerski]

workspace = special:hi, on-created-empty:foot -H echo $TERMINAL

if $TERM is defined, but $TERMINAL isn't, the output of linuxINAL is expected, documented and just how it always has been

[kojq]

When defined, yeah. The issue is it is no longer considered defined when doing recursive vars.

[vaxerski]

please give a minimal reproducible example.

[kojq]

from hyprwm/Hyprland/issues/5172:

$TERMINAL = alacritty
$comms = [workspace special:hyprake] $TERMINAL --class hyprake
workspace = special:hyprake, on-created-empty:$comms

[kojq]

bind = WIN, N, togglespecialworkspace, hyprake

result is no terminal

[kojq]

This should help you see what is happening (linuxINAL):

$TERMINAL = foot
$comms = $TERMINAL
workspace = special:hyprake, on-created-empty:foot -H echo $comms
bind = WIN, N, togglespecialworkspace, hyprake
