Alejandro Lopez
Alejandro Lopez'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 @Lopez-AN 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.

- Reuse a worked example: the commit “Agregado instalador” (9 files · C#).
- Answer from openai_usage_widget's real C# source instead of memory (AI, prompts and agents).
- Where does openai_usage_widget handle “Agregado instalador”?
- What does installer do in openai_usage_widget?
Search the GitHub repository Lopez-AN/openai_usage_widget with XERJ (https://hub.xerj.org/corpus/lopez-an--openai-usage-widget). 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/Lopez-AN/openai_usage_widget openai_usage_widget && git -C openai_usage_widget checkout c2bcc223c3252bef76d5ff7b8d82b892548e2b07 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./openai_usage_widget --url http://127.0.0.1:9200 --prefix openai-usage-widget --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.
