(#599) * less alloc, update migrator, get DesktopNames from .desktop * small cleanup * Update zigini to improve compatibility with old config * Code improvements * Update to zig version 0.12.0 * Some fixes * tiny changes * remove useless comment * migrator changes, and small things * set XDG env vars differently * free memory on error when appending environments * Fix out of bounds issue when using the Delete key Signed-off-by: AnErrupTion <anerruption@disroot.org> * Update zig-ini to fix configuration issue (#603) * Mention display-manager-init for Gentoo/OpenRC in readme.md Signed-off-by: AnErrupTion <anerruption@disroot.org> * Tidy up readme.md Signed-off-by: AnErrupTion <anerruption@disroot.org> * Fix authentication in a few edge cases (#604) * fix loginConv and auth * fix potential mem leak with configs * BIG changes --------- Signed-off-by: AnErrupTion <anerruption@disroot.org> Co-authored-by: アシュ <120780645+Kawaii-Ash@users.noreply.github.com>
