#### 6.7`` API for Paths Relative to "collects"

( require setup/main-collects )

( path->main-collects-relative path)
→ ( or/c path? ( cons/c 'collects ( listof bytes? )))
path : ( or/c bytes? path-string? )

Checks whether path has a prefix that matches the prefix to the main "collects" directory as determined by ( find-collects-dir ). If so, the result is a list starting with 'collects and containing the remaining path elements as byte strings. If not, the path is returned as-is.

The path argument should be a complete path. Applying simplify-path before path->main-collects-relative is usually a good idea.

For historical reasons, path can be a byte string, which is converted to a path using bytes->path.

( main-collects-relative->path rel) → path?

rel

:

( or/c bytes? path-string?
( cons/c 'collects
( or/c ( listof bytes? ) bytes? )))

The inverse of path->main-collects-relative: if rel is a pair that starts with 'collects, then it is converted back to a path relative to ( find-collects-dir ).

For historical reasons, a single byte string is allowed in place of a list of byte strings after 'collects, in which case it is assumed to be a relative path after conversion with bytes->path.

Also for historical reasons, if rel is any kind of value other than specified in the contract above, it is returned as-is.
