Joplin · #15521 WYSIWYG link dialog fix · Francesco

01 · The problem

Selecting text + invoking the link command parks the cursor on the wrong field

In the Joplin Rich Text Editor (WYSIWYG), if you select some text and trigger the "Insert hyperlink" command (toolbar button or Ctrl+K), TinyMCE's built-in link plugin opens a dialog with two fields: "Text to display" (pre-populated from your selection) and "Url" (empty, the one you actually want to fill). Focus lands on the "Text to display" field. You have to tab once before the keyboard reaches the URL field, every single time, on every Joplin desktop install.

Why this is annoying enough to fix

The Joplin team uses TinyMCE's built-in link plugin without any focus override (see apps/app-desktop/gui/NoteEditor/NoteBody/TinyMCE/TinyMCE.tsx). The default TinyMCE focus behaviour is correct for the empty-selection case (cursor goes to the URL field by default), but when text is pre-populated the focus stays on the text field, which the user already filled by virtue of having selected text. One extra keystroke per link, every link, every note.

02 · The fix

A pure-function predicate + a defensive OpenWindow handler

The fix isolates the focus-decision logic in a brand-new pure function so it can be unit-tested without firing up Electron, then wires it into the existing TinyMCE setup callback via the OpenWindow event with a defensive try/catch, so future TinyMCE upgrades that change the dialog API degrade gracefully to the default focus behaviour.

The new predicate

// apps/app-desktop/gui/NoteEditor/NoteBody/TinyMCE/utils/shouldFocusLinkUrl.ts
// Decide whether to re-focus the URL field on a TinyMCE link dialog.
// Returns true only when the `text` field discriminator is present,
// `text` is a non-empty string (pre-populated from a selection),
// and `href` is missing or empty (user has not typed a URL yet).
export default function shouldFocusLinkUrl(data: LinkDialogData | undefined | null): boolean {
  if (!data) return false;
  if (!('text' in data)) return false;
  const hasText = typeof data.text === 'string' && data.text.length > 0;
  const hasHref = typeof data.href === 'string' && data.href.length > 0;
  return hasText && !hasHref;
}
      

The wire-up in TinyMCE.tsx

// inside the existing setup(editor) callback
editor.on('OpenWindow', (event: any) => {
  if (!event?.dialog) return;
  try {
    const data = event.dialog.getData?.();
    if (shouldFocusLinkUrl(data)) {
      event.dialog.focus('href');
    }
  } catch (_error) {
    // getData / focus can throw on dialogs without form fields;
    // safe to ignore - falling back to TinyMCE's default focus.
  }
});
      

Existing-link edits (both text and href populated) keep their default focus, so the change never steals focus from a click target. Image dialogs and any other plugin dialog without a text field are excluded by the discriminator check.

03 · The tests

Twelve jest cases, all green in the actual Joplin app-desktop workspace

The companion shouldFocusLinkUrl.test.ts file lives next to the source (same pattern as the existing shouldPasteResources.test.ts in the same directory) and uses parametric test.each to cover every shape of dialog data the predicate might see.

The twelve cases

pre-populated text + empty href → focus URL
pre-populated text + missing href key → focus URL (missing treated as empty)
pre-populated text + non-empty href (existing-link edit) → leave focus
empty text + empty href (fresh insert, no selection) → leave default focus
empty text + non-empty href → leave focus
undefined data → no focus action
null data → no focus action
empty object (no text key) → no focus action
object with only href, no text key → no focus action
image dialog shape (src/alt) → no focus action
text is non-string (defensive) → no focus action
whitespace-only href counts as non-empty → leave focus

Belt-and-suspenders verification. Tests pass in two environments: (1) isolated ts-jest setup outside the workspace; (2) corepack yarn workspace @joplin/app-desktop test shouldFocusLinkUrl in the actual Joplin monorepo, same toolchain Joplin CI uses on PRs. 12/12 PASS, 6.122s.

04 · The outcome

Direct response from the project lead, PR closed for capacity, not for merit

PR #15544 opened against dev, CodeRabbit-reviewed, 12/12 tests green in CI scope, CLA signed. Laurent Cozic (Joplin project lead) personally responded within ~1.5 hours of the PR opening, soft-declined for review-capacity reasons, and closed the PR after a gracious thank-you exchange.

Done

PR opened, CodeRabbit + CLA passed, 12/12 tests green

Branch fix/15521-wysiwyg-link-dialog-focus, four commits (initial fix, CodeRabbit review fix, test alignment, JSDoc). Identity rewrite via filter-branch + force-push fixed an initial CLA blocker, lesson captured and applied to every subsequent target.

Done

Laurent22 personal response within 1.5h

Direct quote: "Hello, sorry we are not considering new pull requests at this time as we do not have the capacity to review them. I would suggest for now to maybe create a tech spec from this PR and attach it to the issue, so that it can be considered at a later time."

Done

Gracious reply + Laurent closed the PR

Reply acknowledged the capacity transparency without pushing back; left the PR open as draft and explicitly invited Laurent to close it whenever convenient for triage. Laurent closed the PR shortly after.
