Description : compose Multiple Go Filesystems
The [release of version 1.16](
https://golang.org/doc/go1.16) of the Go
programming language included a standard interface for read-only filesystems,
defined in Go's `io/fs` standard library package. With this change came some
other standard-library changes, including the fact that `archive/zip` now
provides a "filesystem" interface for zip files, or the ability of `net/http`
to serve files from any filesystem providing the `io/fs` interface. In
conjunction, this means utilities like the HTTP server can now directly serve
content from zip files, without the data needing to be extracted manually.
.
While that's already pretty cool, wouldn't it be nice if you could, for
example, transparently serve data from multiple zip files as if they were a
single directory? This library provides the means to do so: it implements the
`io/fs.FS` interface using two underlying filesystems. The underlying
filesystems can even include additional `MergedFS` instances, enabling
combining an arbitrary number of filesystems into a single `io/fs.FS`.
.
This repository provides a roughly similar function to [laher/mergefs](
https://github.com/laher/mergefs),
but it offers one key distinction: correctly listing contents of merged
directories present in both FS's. This adds quite a bit of complexity. However,
laher/mergefs will be more performant for filesystems not requiring directory-
listing capabilities.
