Nobody expects the Ziguanas (#517)
* Add build.zig, remove makefile, add .idea directory to .gitignore * Remove submodules, add projects directly * Remove submodules * Add projects * Rename sub/ to dep/, remove makefiles * Rewrite main.c * Remove Argoat dependency * Remove unused dependencies * Rewrite config.c * Add files * Change default fg to 8 in config.ini * Partially rewrite utils.c * Use Zig package manager * Rewrite INPUTS enum in Zig * Commit unfinished full rewrite (Zig 0.11.0) What needs to be dealt with: - Matrix animation - Authentication part - Testing on actual TTY (not just virtual console) Signed-off-by: AnErrupTion <anerruption@disroot.org> * Implement more (untested) authentication code Signed-off-by: AnErrupTion <anerruption@disroot.org> * Fix some bugs (hopefully) Signed-off-by: AnErrupTion <anerruption@disroot.org> * Try to fix some more bugs Signed-off-by: AnErrupTion <anerruption@disroot.org> * Oops, forgot to allocate hehe Signed-off-by: AnErrupTion <anerruption@disroot.org> * Changes in the Zig rewrite (#596) * Everything * make matrix.zig a bit cleaner * make long lines shorter and add changelog * vi mode * update changelog * get errors from child process and (hopefully) fix some other things * fix utmp entry * run authentication in a child process * update changelog * small code improvements * change that * clear terminal on SIGTERM * Remove LogFile * moved ini to a lib, fixed alternative langs * fix logging out * oops * code improvements * consistency * clearing the env isn't needed anymore (afaik) * replace vi_mode with a bool * type aliases, avoiding zeroes(), breaking a long line * lowercase insert/normal, merge conditionals, code improvements * Add experimental save file migrator + bug fixes + add "-dev" version suffix Signed-off-by: AnErrupTion <anerruption@disroot.org> * Resolve conflicts Signed-off-by: AnErrupTion <anerruption@disroot.org> * Clean up when SIGTERM is received (#597) * clean up child processes on SIGTERM * small code improvement * consistency.. i guess? * Properly set XDG_CURRENT_DESKTOP Signed-off-by: AnErrupTion <anerruption@disroot.org> * Zig 0.12.0 and more! (#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>
