0.4.1

0.4.1 — 2026-04-23

Fixed

• fast_edit(replace='ClassName', ...) no longer spuriously rejects field-only class snippets. The safety guard that blocks multi-symbol replace= snippets (to prevent silent deletion of nested methods) now uses tldr structure's per-definition kind classification: methods and functions count as extras, field/variable/constant declarations do not. Previously the guard couldn't distinguish private int size = 100; from public void set(...), so any replace=ClassName snippet containing a full class body with only a field change was rejected even though the edit was a safe direct swap. tldr is already a fastedit prerequisite (used by fast_read, fast_search, fast_references), so this inherits accurate per-language extraction across all 13 supported languages at ~10 ms per call. Falls back to the in-process AST analyzer if tldr is temporarily unavailable. Closes the test_batch_edit_mixed_preserve_siblings regression that had been carried in the backlog.
• Signature-presence check now recognizes Java / C# / TypeScript access modifiers. The internal helper that decides whether to auto-preserve a function/class signature (omitted signature → prepend from AST) only knew Rust's pub and TypeScript's export. public class Cache { ... }, private static final class Foo { ... }, and similar snippets were classified as "signature missing" and got their declaration prepended a second time, producing duplicated lines once the guard above stopped blocking them. The helper now accepts any sequence of modifier keywords before class / struct / interface / trait / enum / impl, and skips comment-prefixed lines (//, #, *, --) to avoid false positives from declarations referenced inside doc comments.

Changed

• fastedit doctor now reports the tldr version (tldr /path/to/tldr (v0.1.4)) and treats tldr as a required dependency rather than optional, reflecting its role in the edit guard, fast_read, and fast_search. Missing-tldr now produces a failing row (exit code 1) instead of a skip.

Tests

• 7-case regression lock for the field-vs-method guard invariant across Python, Java, Rust, and TypeScript. Field-only class snippets pass silently; method-containing snippets raise ValueError with the same additional symbol(s) message as before. Locks both halves of the invariant so future changes to the guard can't regress one in favor of the other.
