More ini flexibilty

[basxto]

A few things I noticed, which seemed unhandy.

• I had to repeat the path to WC3 a lot
  • variables or at least some base variable that can be defined and used in paths ($0 maybe)
• ~~ini always loaded from the working directory~~
  • unhandy if warsmash gets installed to a read-only location
  • ~~could be first command line argument or probably via --ini-path= (would allow to directly load maps via the first argument or something like that)~~ -ini
  • trying to load it from standard directories like $HOME/.config/warsmash/warsmash.ini (XDG basedir is a lot more comlex than that simplification) … maybe something like https://codeberg.org/dirs/directories-jvm

ini in a ~/.config directory + map files via cli would theoretically allow on Linux to associate warsmash with WC3 maps via XDG Mime types (associates a desktop file with a mime type or file extension) and XDG Desktop files (explains how to run program). example here
