Roberto Antonio Berrospe Machin
Roberto Antonio Berrospe Machin'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 @iBobX 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 RapidR corpus
iBobX/RapidR: RapidQ-compatible BASIC, built new in Rust: native, interpreted and web, with RapidR Studio
- Reuse a worked example: the commit “The chat's card links (Open, Undo, Review) are reachable by Tab: a ma…” (5 files · Rust, JavaScript).
- Answer from RapidR's real Rust source instead of memory (Web and frontend platform).
- What does crates/rapidr-ui-kernel do in RapidR?
Search the GitHub repository iBobX/RapidR with XERJ (https://hub.xerj.org/corpus/ibobx--rapidr). 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/iBobX/RapidR RapidR && git -C RapidR checkout 963fa345512da9f821442ec4616e5fad238c0c63 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./RapidR --url http://127.0.0.1:9200 --prefix rapidr --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.
