Simon Field
Simon Field'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 @DaFa66 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 phpup corpus
DaFa66/phpup: Command line toolkit for managing local PHP development environments. Lightweight, configurable and built for power users
- Look up how phpup implements apache, command-line, dev-environment, with answers cited to file and line.
- Reuse a worked example: the commit “elevate the verb, not the panel; tidy the chrome” (4 files · Rust).
- Answer from phpup's real Rust source instead of memory (Web and frontend platform).
- Where does phpup handle “elevate the verb, not the panel; tidy the chrome”?
- How does phpup implement apache?
- What does panel do in phpup?
Search the GitHub repository DaFa66/phpup with XERJ (https://hub.xerj.org/corpus/dafa66--phpup). 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/DaFa66/phpup phpup && git -C phpup checkout ceefb344aea986766b1a9ea95dd4c51a3b2f7cbc 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./phpup --url http://127.0.0.1:9200 --prefix phpup --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.
