- src/main/UrlTitle.js — fetch a URL, return its <title>. Pure module
with injectable fetch for tests. Decodes named + numeric + hex entities
(AT&T, Café, —), strips the <title> tags, collapses
whitespace, caps the label at 200 chars. 5s timeout via AbortController,
2 MiB body cap to avoid OOM on big downloads, streaming reader with
overflow cancellation. Rejects non-http(s) URLs up front.
- src/main.js — IPC url-title:fetch proxies to fetchTitle.
- src/editor/smart-paste.js — CodeMirror 6 extension that detects
URL-only pastes (one URL, surrounded only by whitespace), inserts the
URL immediately, then async-rewrites the insertion range to
[Title](url) once the title arrives. Multi-line / prose pastes pass
through untouched.
- src/editor/codemirror-setup.js — accepts smartPasteFetcher option and
pushes the extension when provided.
- src/renderer.js — passes ipcRenderer.invoke('url-title:fetch') as
the fetcher.
- src/preload.js — url-title:fetch added to ALLOWED_SEND_CHANNELS.
- eslint.config.js — AbortController / TextDecoder / TextEncoder added
to globals (available in Node 20+ and Chromium).
Tests (34 new):
- tests/main/UrlTitle.test.js (24): isHttpUrl scheme filter, decodeTitle
named/numeric/hex entities + whitespace + non-string, extractTitleFromHtml
first match + case-insensitive + null fallback, fetchTitle success +
long-title cap + streaming body, all failure paths (non-http,
no-fetch, non-OK, wrong content-type, no <title>, network error,
body over maxBytes — including streaming overflow cancellation).
- tests/smart-paste.test.js (10): URL_ONLY_RE detection (bare URL,
path/query/fragment, whitespace padding, scheme rejection, embedded
rejection, empty/malformed), replacement format ([T](url), brackets
in title survive, query strings preserved).
Full suite: 71 suites, 831 tests, lint+format clean.
