Finding code

Search modules by name, by the code inside them, or by what they export.

A version contains around 187,000 modules. Searching is how you get from a hunch to a file path.

Search

cellar module search --name 'Passkey' --filter protocol

12 module(s) matched of 12 considered

WASmaxMdGetPasskeyRequestOptionsRPC   /Users/you/.cellar/bundles/whatsapp-1044822804/modules/WASmaxMdGetPasskeyRequestOptionsRPC.js
WASmaxMdSetPasskeyPrologueRPC         /Users/you/.cellar/bundles/whatsapp-1044822804/modules/WASmaxMdSetPasskeyPrologueRPC.js
…

Three things you can match on, and they combine:

Flag	Matches against
--name	The module name
--source	The code inside the module
--exports	The names the module exports

cellar module search --name '^WAWeb' --source 'addonType' -C 2
cellar module search --exports 'sendStanza'

Combining --name with --source is much faster than --source alone. The name pattern is applied to the index in memory, so only the surviving files are ever opened. That is the difference between reading forty files and a hundred and eighty thousand.

grep

cellar grep is shorthand for a source search.

cellar grep 'disappearing_mode' --filter protocol -C 1

15 module(s) matched of 4715 considered (showing 3)

WASmaxInAccountSyncNotificationDisappearingModeMixin  /Users/you/.cellar/…/WASmaxInAccountSyncNotificationDisappearingModeMixin.js
        │ 	function e(e) {
      3 │ 		var t = o("WASmaxParseUtils").assertTag(e, "disappearing_mode");
        │ 		if (!t.success) return t;

Because the unpacked modules are ordinary files, your own tools work too:

grep -rl 'disappearing_mode' ~/.cellar/bundles/whatsapp-1044822804/modules/

Reading a module

cellar module show WASmaxOutMdGetPasskeyRequestOptionsRequest

WASmaxOutMdGetPasskeyRequestOptionsRequest
  path:      /Users/you/.cellar/bundles/whatsapp-1044822804/modules/WASmaxOutMdGetPasskeyRequestOptionsRequest.js
  bundle:    whatsapp-1044822804

  size:      390 B raw / 445 B stored
  deps:      WASmaxJsx, WASmaxOutMdBaseIQGetRequestMixin, WAWap
  dependents: WASmaxMdGetPasskeyRequestOptionsRPC
  exports:   (none)

--- source ---
     1 │ __d("WASmaxOutMdGetPasskeyRequestOptionsRequest", [
     …

Useful flags:

cellar module show WAWebSendMsgStanza --start 40 --lines 20   # a slice
cellar module show WAWebSendMsgStanza --path-only              # just the path
cellar module show WAWebSendMsgStanza --json                   # metadata as JSON

If the name is wrong, the error lists near matches instead of just failing.

Export formats

Both commands take --json.

cellar module show WASmaxOutMdGetPasskeyRequestOptionsRequest --json

Chain it:

cellar module search --name '^WAWebNewsletter' --json | jq -r '.hits[].path'

Reading results carefully

Search results report matched (the true count) separately from the hits returned, and set truncated: true when the list was cut. A short list is never silently a complete one. Modules that could not be read are listed under unreadable rather than dropped.
