Hyeon Jeon
Hyeon Jeon'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 @hj-n 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 ggaction corpus
ggaction/ggaction: A grammar of graphical actions
- Look up how ggaction implements chart, charting-library, data-visualization, with answers cited to file and line.
- Reuse a worked example: the commit “Add native Canvas transition scenes and rendering” (9 files · JavaScript, TypeScript).
- Answer from ggaction's real JavaScript source instead of memory (API design and specification).
- Where does ggaction handle “Add native Canvas transition scenes and rendering”?
- How does ggaction implement chart?
- What does src/renderers do in ggaction?
Search the GitHub repository ggaction/ggaction with XERJ (https://hub.xerj.org/corpus/ggaction--ggaction). 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/ggaction/ggaction ggaction && git -C ggaction checkout 0384b9278638d5d23e87d4377415be45b59759f6 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./ggaction --url http://127.0.0.1:9200 --prefix ggaction --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.
