yingfeng0704
yingfeng0704'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 @yingfeng0704 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 indexer corpus
sat20-labs/indexer: sat20-labs/indexer (Go)
- Reuse a worked example: the commit “support regtest network” (32 files · Go).
- Answer from indexer's real Go source instead of memory (Databases and storage engines).
- Where does indexer handle “support regtest network”?
- What does indexer do in indexer?
Search the GitHub repository sat20-labs/indexer with XERJ (https://hub.xerj.org/corpus/sat20-labs--indexer). 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/sat20-labs/indexer indexer && git -C indexer checkout e25ac6c8ca34e794d0a9e966125ac30a0fff8796 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./indexer --url http://127.0.0.1:9200 --prefix indexer --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.
