* fix(editor): preserve U+00A0 non-breaking space (#3037) Non-breaking spaces were silently normalized to regular spaces at every ingestion point, so typed/pasted/imported nbsps never reached the changeset and users could not glue words against line-wrap in French or other languages that require nbsp typography. Removed the four strip sites that replaced U+00A0 with U+0020: - src/node/db/Pad.ts cleanText - src/static/js/contentcollector.ts textify - src/static/js/ace2_inner.ts textify - src/static/js/ace2_inner.ts importText raw-text guard Updated both processSpaces functions (domline and ExportHtml) to tokenize U+00A0 as a separate unit, emit it verbatim as , and treat it as content (not whitespace) for the run-collapse bookkeeping so adjacent regular-space runs aren't miscounted. Added backend round-trip tests for spliceText and setText, and extended the cleanText case table. Updated the existing contentcollector and importexport specs whose expectations encoded the previous buggy behavior; they now assert genuine nbsp preservation. Verified manually in Firefox: clipboard U+00A0 → paste → pad → getText returns c2 a0; getHTML emits `100 km`. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(contentcollector): collapse display-artifact nbsp runs on DOM read-back processSpaces is a lossy one-way display transform: leading/trailing spaces and all-but-the-last of a run get rendered as so HTML doesn't collapse them. When incorporateUserChanges reads text back from the DOM, those display-artifact nbsps were being stored in the changeset model instead of being normalized back to plain spaces. This broke handleReturnIndentation, whose /^ *(?:)/ regex only matches ASCII spaces: auto-indent after `foo:\n` produced 4 spaces instead of the expected prev-indent (2) + THE_TAB (4) = 6, because the previous line's model had nbsps where it used to have spaces. Fix: in contentcollector.textify, collapse any [ ]+ run back to plain spaces UNLESS the run is pure U+00A0 AND strictly interior to word chars. That preserves user-intended typographic nbsps like "100 km" while undoing the one-way display transform. Updated 7 contentcollector tests and 7 importexport tests whose assertions needed to reflect the new rule (boundary/mixed runs collapse; pure-interior nbsp runs preserve). Fixes the Playwright regression in indentation.spec.ts:117 that the previous commit introduced. * fix(contentcollector): canonicalize nbsp runs at line assembly, not per text node Addresses Qodo code review feedback on PR #7585. ## Bug fix — nbsp lost at DOM text-node boundary The previous approach ran the "collapse display-artifact nbsp" rule inside textify(), which is called per individual DOM TEXT_NODE. A user-intended nbsp sitting at a text-node boundary (e.g., <span>100</span><span> km </span>) was incorrectly seen as non-interior (before === '' for the second text node) and normalized back to a regular space. Fix: move the canonicalization out of textify() and run it on each fully assembled line string inside cc.finish(). The rule remains: [ ]+ run -> plain spaces UNLESS pure U+00A0 AND strictly interior to non-ws chars It is length-preserving, so attribute offsets and line lengths are unaffected. Added a regression test (contentcollector.spec.ts) for the cross-span case. ## Docs concern Reverted the type-only addition of spliceText to PadType. spliceText is an existing Pad runtime method; the backend test now uses a cast (`(pad as any).spliceText`) so the PR does not expand the declared public type surface, avoiding a separate documentation requirement. --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |
