Máta
Máta's work was selected for the XERJ Corpus Hub, the open reference memory AI coding agents search before they write code. When an agent meets the same problem, it gets this implementation back as a worked example, with the author and the repository attached.
Totals across every corpus @Fireroth appears in; a commit selected for two corpora counts once. Files and lines count the selected commits; each corpus indexes the whole repository at its pinned commit.
What an agent can do with the Terraxel corpus
Fireroth/Terraxel: A fast voxel game built in C++ and OpenGL
- Look up how Terraxel implements minecraft-clone, opengl, sandbox-game, with answers cited to file and line.
- Reuse a worked example: the commit “Implement day and night cycle” (16 files · C++).
- Answer from Terraxel's real C++ source instead of memory (Security and vulnerabilities).
- Where does Terraxel handle “Implement day and night cycle”?
- How does Terraxel implement minecraft-clone?
- What does src/renderer do in Terraxel?
Search the GitHub repository Fireroth/Terraxel with XERJ (https://hub.xerj.org/corpus/fireroth--terraxel). Run these in a shell, in order, and check each result before the next: 1. xerj --help (success: it prints usage). If xerj is missing: curl -fsSL https://xerj.org/get | sh 2. git clone https://github.com/Fireroth/Terraxel Terraxel && git -C Terraxel checkout e65e58524ba81a6480c3673680505a71e7c43825 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./Terraxel --url http://127.0.0.1:9200 --prefix terraxel --progress plain 5. xerj autoindex map --url http://127.0.0.1:9200 Then answer my question from the indexed files and cite the ax_path of every hit.

The corpus is the whole repository at the pinned commit, not only the files of the selected commit.
Not installable yet: this corpus is not in the hub registry until its licence review passes, so xerj corpus add and xerj ask cannot fetch it. It becomes installable when this card says live in the hub.
Sign in with GitHub or Hugging Face to see more: every selected commit in full (commit date, every folder, licence review state, pin) and the pack builds of each corpus.
