Root cause found via gdb backtrace on the runner (thread::pool_init crashed from main -> testing runner): the CI container sets `ulimit -s unlimited`, so getrlimit(RLIMIT_STACK) returns RLIM_INFINITY. core:thread passes that to pthread_attr_setstacksize, pthread_create fails, and thread.create() returns nil, which core:testing's pool_init dereferences without a nil check. Reproduced and confirmed fixed in an ubuntu:24.04 container with the same Odin build. `just test` now clamps the stack limit before running odin test. Also removes the gdb diagnostic step added to debug this. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
HanjaKanaMun
Odin + raylib memory card game for learning Japanese, Korean and Thai scripts.
Match each symbol with its reading: hiragana and katakana with romaji, Hangul letters with their Revised Romanization, and Thai consonants with their sound and name word. Three difficulties (6, 12 or 16 pairs), best scores per deck, and a card deck themed on each country's flag.
Controls
| Mouse | Click cards and buttons |
| Arrows / WASD / hjkl | Move between cards |
| Enter / Space | Flip the selected card (Enter also plays again) |
| 1-3 | Pick a language or deck in menus |
| Left / Right | Change difficulty |
| Esc | Back (quits from the main menu) |
Scores are saved to profile.json in the user data folder (~/Library/Application Support/HanjaKanaMun
on macOS, ~/.local/share/HanjaKanaMun on Linux, %APPDATA%\HanjaKanaMun on Windows).
Development
Requires Odin (dev-2026-09) and just.
just run # build and play (debug)
just check # type-check with -vet
just test # run tests
just package 1.0 # native release build -> build/HanjaKanaMun_1.0_<os>_<arch>.tar.gz
just windows-deps # Linux only: fetch Windows SDK/CRT (xwin) and raylib.lib
just package-windows 1.0 # cross-compiled Windows build -> build/HanjaKanaMun_1.0_windows_x86_64.zip
The Windows build needs lld-link. On macOS, brew install lld and set LLD_LINK, and point XWIN_SDK and
RAYLIB_WINDOWS at an xwin splat and Odin's Windows vendor/raylib/windows folder (the Linux/macOS Odin releases
don't include raylib.lib).
Neovim
ols.json and odinfmt.json configure the ols language server and formatter.
Install ols (e.g. :MasonInstall ols) and enable it with nvim-lspconfig: vim.lsp.enable('ols').
Formatting goes through ols (vim.lsp.buf.format()), or just fmt if odinfmt is on your PATH.
CI
.gitea/workflows/gitea-build.yaml: check, test and build on pushes and PRs tomainanddevelop, plus a Windows cross-build so link problems show up before a release..gitea/workflows/gitea-release.yaml: on a version tag likev1.0, builds Linux and Windows packages, uploads them to the Gitea generic package registry (HanjaKanaMun/1.0) and creates a Gitea release with both attached. Needs aTOKENsecret with package write access..gitea/actions/setup: shared toolchain setup (apt packages, Odin, just).
Release: git tag v1.0 && git push origin v1.0
