Multipe groups of monitors - how to source a different collection of configuration automatically or on-demand?

[llinfeng]

I use a work laptop in multiple locations (home/office), where each had a distinct collection of monitors. For each set of monitors, with one komorebi.json file, I can configure how monitors are enumerated and specify the layout for each workspace on those monitors.

The question, then, is how to source a different komorebi.json when I switch to a different set of monitors. I see two paths, and would like to learn from others who have a similar need:

1. To update the environmental variable KOMOREBI_CONFIG_HOME on-demand - as documented on this page, one can opt to use a different directory to store komorebi-related files.
2. [drop for now] Or, can one abuse the "monitors" and "display_index_preferences" setting, so that a total of some 15 (or so) monitors can be uniquely identified and assigned with monitor-specific workspace and thus workspace-layout?

For path 1, here is a checklist on implementation:

• Use Autohotkey to modify system's environmental variable by calling setx. With this, that KOMOREBI_CONFIG_HOME can be set to point to a different directory based on the monitor configuration (like, the width and height of the entire workspace, which should be unique per each set of monitors).
• In each separate directory that housing the komorebi.json file, configure a "local" komorebi.json file for use. Note, it is important to keep the same number of dictionaries under "monitor": [] and "display_index_preferences: {}".

For path 2, it is dropped for now, as there is an implicit but necessary one-to-one mapping between dictionaries under "monitor": [] and entries in "display_index_preferences: {}".

[Edited] With AHK v1, the following function will populate the Environmental Variable KOMOREBI_CONFIG_HOME with the input (full path, without ending slash \).

SetKomorebiConfigHome(Path) {
    ; Define the environment variable name
    VarName := "KOMOREBI_CONFIG_HOME"
    ; Construct the command to set the environment variable permanently
    Command := "setx " . VarName . " """ . Path . """"
    ; Run the command
    RunWait, %ComSpec% /c %Command%, , Hide
    return Command
}

Usage: in folder "c:\Users\full_path\monitor_set1", keep a simple komorebi.json file with monitor+workspace configurations adjusted to that set of monitors. Then, call SetKomorebiConfigHome before starting Komorobi through AHK, as below.

" Update the KOMOREBI_CONFIG_HOME env var for the OS
" Note, it is important NOT to including an ending slash for the full path, for AHK v1 to parse the string properly.
Path := "c:\Users\full_path\monitor_set1"
command := SetKomorebiConfigHome(Path)
" Run Komorebi on-demand
run, c:\Program Files\komorebi\bin\komorebic.exe start

Side note: EnvSet and EnvGet are simply AHK v1 methods, and won't necessarily touch the Environmental Variable of the Windows OS.
