Editor: no live completion and no snippets (P31); P29b and the double tap checked - #28

Two parts: P31 (completion and snippets off) changes the macro. For P29b (failing doctests) and the double tap, my tests found nothing to fix, so there's no code change for them.

P31: no live completion and no snippets in glpython blocks

Since LiaScript 2.1.1, every executable block completes as one types and expands snippets. if + Enter (or + Tab) became if condition: / # TODO: write code..., also in a docstring.

The macro now sets enableLiveAutocompletion = false and enableSnippets = false on the block's lia-editors. It works the same way as the existing tabSize/useSoftTabs (in indentWithSpaces, run from attach() on every re-render):

• It only writes when the value differs.
• It skips an editor that isn't upgraded to LiaScript's element yet.
• A block's own data-ace-options that names one of the two options wins.

Ctrl+Space stays (enableBasicAutocompletion). It only opens on request; without snippets it offers keywords and the block's own words, and Escape closes it. On the iPad there's usually no Ctrl+Space at all.

README («The macro makes the block's editor indent…») and CLAUDE.md are updated.

Tested (Chrome, headless, hosted LiaScript player, local course version: 1.0.0)

P29b: «Tests» with failing doctests – not reproduced

The same test as in #27, now with failing doctests, run with the macro from main. I recorded LiaScript's IndexedDB record (code store) right after the click and after the result.

Passing doctests (#27's table) are kept as before.

From LiaScript's source, too: Eval stores the new version (appendVersion → updateAppend) at the click, and the result only updates that version's log. The writes run in Dexie transactions, so they can't overwrite each other.

Double tap on «Tests»: no problem

LiaScript runs the block's script synchronously inside the click on its run button. So commandAfterLiaRun is used up before the second click can overwrite it: the single slot is enough, and no glpython:run follows. No change.

Manual tests

Chrome on the desktop:

1. Etappe 2, «Eine Funktion ruft eine andere auf»: in main.py type a docstring line ending in if, press Enter: new line, no popup. The same with Tab: spaces, no snippet.
2. Same after ▶, after the version arrows, and after going to the next slide and back.
3. Ctrl+Space still opens a small list on request, and Escape closes it.

iPad (Safari, software and hardware keyboard if available):
4. Same as 1. With the software keyboard: if then the return key gives a new line, no popup.
5. Typing a whole word with the software keyboard's suggestions (QuickType) still works normally.
6. P29b: change main.py so the doctests fail, «Tests», close the tab, open the course again: the change is there.

Follow-ups (not fixed here)

• P29b remains open on your side. I couldn't make the change get lost. If it happens again, please paste the snippet below into DevTools (Console) on the slide before the reload: it shows how many versions LiaScript stored and the code it keeps.
• Test harness: after a «Tests» run, a new indexedDB.open from Playwright's page.evaluate sometimes throws SecurityError: Blocked by policy, until a reload. LiaScript itself keeps storing (it holds its connection from loading: verified with a further change and reload). It only matters for scripts that read IndexedDB: read once right after loading.
• Other non-glpython blocks in a course (e.g. ```text exercises with a LiaScript script) still have live completion; the macro only touches its own block.

Snippet: what LiaScript stored for the slide's code

// In DevTools (Console) on the course's tab, on the slide: what LiaScript has stored for its code blocks.
(async () => {
  const name = decodeURIComponent(location.search.slice(1))
  const section = Number(location.hash.slice(1)) - 1
  const db = await new Promise((ok, ko) => { const r = indexedDB.open(name); r.onsuccess = () => ok(r.result); r.onerror = ko })
  const rows = await new Promise((ok) => { const r = db.transaction('code').objectStore('code').getAll(); r.onsuccess = () => ok(r.result) })
  for (const row of rows.filter((row) => row.id === section)) {
    row.data.forEach((block, i) => console.log(`DB ${name} | slide ${section + 1}, block ${i} (DB version ${row.version}): ${block.version.length} versions, active ${block.version_active}`,
      block.file.map((file) => `\n--- ${file.name || '(ohne Name)'}\n${file.code}`).join('')))
  }
  if (!rows.some((row) => row.id === section)) console.log(`nothing stored for slide ${section + 1} in ${name}`)
  db.close()
})()

Run it once right after loading the slide, then again after «Tests»: right after the click, the active version should be the new code.
