Yuriy Pisarev
Yuriy Pisarev'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 @pisarev 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 pascal-mathparser corpus
pisarev/pascal-mathparser: Expression parser and virtual machine for Object Pascal, with an x86-64 JIT
- Look up how pascal-mathparser implements delphi, expression-evaluator, free-pascal, with answers cited to file and line.
- Reuse a worked example: the commit “Configure Delphi package projects for IDE builds” (5 files).
- Answer from pascal-mathparser's real source instead of memory (API design and specification).
- Where does pascal-mathparser handle “Configure Delphi package projects for IDE builds”?
- How does pascal-mathparser implement delphi?
- What does packages/delphi do in pascal-mathparser?

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.
