IF
IF'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 @IgorFroehner 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 evolutionary corpus
IgorFroehner/evolutionary: A fully extensible Rust framework for using paralyzed genetic algorithms to solve problems
- Reuse a worked example: the commit “cover the untested operators and fix the bugs they found” (17 files · Rust).
- Answer from evolutionary's real Rust source instead of memory (API design and specification).
- Where does evolutionary handle “cover the untested operators and fix the bugs they found”?
- What does src/mutation do in evolutionary?
Search the GitHub repository IgorFroehner/evolutionary with XERJ (https://hub.xerj.org/corpus/igorfroehner--evolutionary). 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/IgorFroehner/evolutionary evolutionary && git -C evolutionary checkout 159a74658fed034b449603018ce466c34f9af0a0 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./evolutionary --url http://127.0.0.1:9200 --prefix evolutionary --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.
