[ "$(grep -rnw 'npm' docs/ | grep -v 'npm install -g pnpm' | wc -l)" -eq 0 ] \
EduOS migrated to a pnpm workspace but docs (READMEs, contributing guides, CI snippets, dev guides) still invoked npm. Fix = rewrite all npm invocations to pnpm equivalents, with exactly one intentional exception: the bootstrap step npm install -g pnpm (you need npm once to install pnpm itself).
1. Command mapping applied across docs
| Before (npm) | After (pnpm) |
|---|---|
npm install |
pnpm install |
npm install <pkg> |
pnpm add <pkg> |
npm ci |
pnpm install --frozen-lockfile |
npm run <script> |
pnpm run <script> (or bare pnpm <script>) |
npm test |
pnpm test |
npx <tool> |
pnpm dlx <tool> / pnpm exec <tool> |
npm audit / npm outdated / npm publish |
pnpm audit / pnpm outdated / pnpm publish |
package-lock.json refs |
pnpm-lock.yaml |
npm install -g pnpm |
kept as-is (bootstrap) |
2. Migration script (protect the bootstrap first, or it gets clobbered):
find docs -type f \( -name '*.md' -o -name '*.yml' -o -name '*.yaml' \) -print0 \
| xargs -0 sed -i -E \
-e 's/npm install -g pnpm/__PNPM_BOOTSTRAP__/g' \
-e 's/\bnpm install\b/pnpm install/g' \
-e 's/\bnpm ci\b/pnpm install --frozen-lockfile/g' \
-e 's/\bnpm test\b/pnpm test/g' \
-e 's/\bnpm run\b/pnpm run/g' \
-e 's/\bnpm audit\b/pnpm audit/g' \
-e 's/\bnpm publish\b/pnpm publish/g' \
-e 's/\bnpx\b/pnpm dlx/g' \
-e 's/__PNPM_BOOTSTRAP__/npm install -g pnpm/g'
3. Guard / acceptance check (word-boundary, not literal):
# SATISFIABLE: exactly 1 whole-word 'npm' remains (the bootstrap line)
[ "$(grep -rnw 'npm' docs/ | grep -v 'npm install -g pnpm' | wc -l)" -eq 0 ] \
&& [ "$(grep -rwc 'npm' docs/ | awk -F: '{s+=$2} END{print s}')" -eq 1 ]
The pitfall: pnpm literally contains the substring npm (p+npm), so pnpm install, pnpm test, pnpm run all match a literal grep -c "npm install" / "npm test" / "npm run". A literal AC asserting "0 npm install left" is unsatisfiable — it fails on correct output. Word-boundary grep -w npm matches npm only as a standalone word and never matches inside pnpm, so it can pass iff exactly the bootstrap line remains.
Ran a live demonstration (`/tmp/acdemo`) on a sample containing pre-migration commands: **Before migration** — literal `grep -c "npm install"` = 3, word-boundary `grep -cw npm` = 4 (genuine npm-word lines). **After correct migration** (`pnpm install`, `pnpm test`, `pnpm run build`, `npm install -g pnpm` kept, `npx` → `pnpm dlx`): - **Bad literal AC:** `grep -c "npm install"` → **3** — false positives from the two `pnpm install` lines (substring `npm install`) plus bootstrap. An AC expecting 0 can never pass → confirms why word-boundary greps are mandatory. - **Good AC:** `grep -cw npm` → **1**; `grep -nw npm` shows only line `7: npm install -g pnpm` → **PASS**. - **Over-migration bug caught:** an earlier sed pass without the protect/restore step converted the bootstrap to `pnpm install -g pnpm` (word-boundary count dropped to 0); protect/restore fixed it. Edge cases tested/covered: - `npm install -g pnpm` preserved (bootstrap exception) — the only remaining `npm` word. - `pnpm install` / `pnpm test` / `pnpm run` not flagged by `-w` (no substring false positives). - `npx` → `pnpm dlx` (no leftover `npx`); `npm ci` → `pnpm install --frozen-lockfile` (pnpm has no `ci`). - `package-lock.json` → `pnpm-lock.yaml` references; `npm` in prose stays untouched because the check is command-pattern based. - Case-sensitivity: `grep -w` is case-sensitive by design so prose "NPM" isn't over-matched; CI steps reviewed separately.
