quill-code

@posthog/quill's source lives in this monorepo at packages/quill (repo root, two levels up from products/desktop). Desktop still consumes the published npm package via its nested workspace catalog — products/desktop is excluded from the root pnpm workspace, so workspace: linking cannot reach it. To test an unpublished quill change here, you build quill in-repo, pack it to a tarball, and point a pnpm overrides entry at that tarball. This is a temporary local-dev state — revert before merging (see below).

All commands below run from products/desktop/. Building quill uses the root workspace's install, so run pnpm install at the monorepo root once first.

Quill layout (where to edit)

packages/quill (from the monorepo root) is the workspace (@posthog/quill-workspace). It contains sub-packages, each a layer of the design system:

• packages/primitives/src — base components (Card, Badge, Button, Progress, …)
• packages/components/src — composed components (DataTable, DateTimePicker, Metric)
• packages/blocks/src — product-level blocks (e.g. ExperimentCard). Add the file here and export it from packages/blocks/src/index.ts.
• packages/quill/src — the aggregate that re-exports all layers as @posthog/quill.

A new export in any sub-package flows to @posthog/quill automatically on build.

The loop (every quill change)

1. Edit/add the component in the right sub-package (above) and export it from that package's src/index.ts.

2. Re-sync into products/desktop manually — build → pack → point the override → reinstall:

   # From products/desktop/
   DESKTOP_ROOT="$PWD"
   QUILL_DIR="${QUILL_DIR:-../../packages/quill/packages/quill}"
   
   # a. Build the WHOLE quill workspace (two levels up from the aggregate), so the
   #    sub-packages rebuild BEFORE the aggregate bundles them.
   ( cd "$QUILL_DIR/../.." && pnpm build )
   
   # b. Pack into .local-quill/ under a UNIQUE filename. pnpm pins a tarball by
   #    integrity, so a stable name caches stale across re-syncs — drop old local
   #    tarballs first, then rename the packed file to a unique local name.
   #    (Anchor on $DESKTOP_ROOT, not `git rev-parse --show-toplevel`: the git
   #    toplevel is the monorepo root, not this workspace.)
   rm -f .local-quill/posthog-quill-local-*.tgz
   ( cd "$QUILL_DIR" && npm pack --pack-destination "$DESKTOP_ROOT/.local-quill" )
   mv .local-quill/posthog-quill-[0-9]*.tgz ".local-quill/posthog-quill-local-$(git rev-parse --short HEAD)-$$.tgz"
   
   # c. Point the override at the new tarball, then reinstall.
   #    Edit pnpm-workspace.yaml so overrides['@posthog/quill'] = file:./.local-quill/<new file>
   pnpm install
