…when some amount of text is deleted at the beginning of a file. When this happens, the “affected range” of the buffer is an empty range from (0, 0) to (0, 0). Tree-sitter's `descendantsOfType` function incorrectly returns results when querying this specific range, so we'll sidestep this by explicitly returning early whenever the affected range is empty instead of trying to (re-)populate injections for a range that can't have any.

Fixes #822.
Description of the Change
Implements a simplified API for one window to send a signal to all windows, optionally including itself. (#822 explores scenarios where this could be needed.) We use the main process to act as a broker.
Alternate Designs
I started out envisioning that this would combine reactivity and storage, much like
atom.config. But we can already uselocalStoragefor the storage side, and I didn’t feel like reimplementing the whole thing when what’s most urgently needed is the signaling.Possible Drawbacks
I can’t really think of any. This is a pretty thin layer over Electron’s built-in tools for communicating between the main process and the individual renderer processes.
Verification Process
None yet! This PR is in draft mode while I figure out exactly how I’m gonna test this thing.
Release Notes
atom.signal, an API for sending messages between different Pulsar windows.
