Flysystem Read-Only Adapter
===========================

[](#flysystem-read-only-adapter)

A [League Flysystem](https://flysystem.thephpleague.com/) adapter which wraps another adapter: reads pass through to it, writes and deletes are captured in memory. The underlying filesystem is never modified, but code running on top of it sees its own changes as though they had been written. Uses [league/flysystem-memory](https://flysystem.thephpleague.com/docs/adapter/in-memory/) to store changes.

Created to use for `--dry-run` mode needs: the whole program runs normally – writing files, deleting them, listing directories, reading back what it just wrote – and nothing reaches the disk. This was extracted from [Strauss](https://github.com/BrianHenryIE/strauss), where it implements `strauss --dry-run`.
