# codereviewer-msg-pyjs

`microsoft/codereviewer` fine-tuned on the CodeReviewer **comment-generation**
task (Python + JavaScript). Given a code change (a diff encoded with
`<add>/<del>/<keep>` line markers), it generates a natural-language review comment.

- Base model: `microsoft/codereviewer` (CodeT5 family, pre-trained on diffs+reviews)
- Task: review-comment generation (the CodeReviewer `msg` task)
- Eval: official CodeReviewer smoothed BLEU-4 (`rmstop=True`) = **7.26** on the
  Python/JS test split (reference paper ~5.73).

## Input format
Prefix each diff line with an edit marker, e.g.:
```
<keep> def get_user(conn, username):
<del>     cur.execute("SELECT * FROM users WHERE name = '" + username + "'")
<add>     cur.execute("SELECT * FROM users WHERE name = ?", (username,))
```
