What it is
nlgrep is a developer tool that searches code, docs, logs, and text by meaning using natural-language queries, finding paraphrases and behavior descriptions even when exact words are forgotten.
How it uses Jev
nlgrep uses Jev for every match: it sends the query and included source content to Jev, which returns a probability that the condition is satisfied. Results are ranked by highest-scoring window and filtered by a configurable threshold.
Primitives:noul
Technique worth stealing
Use natural-language conditions with Jev Noul judgments to find code by meaning, with a probability threshold and ranked results.
Try it
npm install --global nlgrep; set JEV_KEY; run nlgrep "query" ./path
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
