synopsis: Deduplicate path separator duplicates | ||
packages: [cabal-install-solver] | ||

||
The "using configuration from" message no longer has duplicates on Windows when | ||
the `cabal.project` uses forward slashes for its imports but the message reports | ||
imports with backslashes. | ||
|
||
```diff | ||
$ cat cabal.project | ||
import: dir-a/b.config | ||
|
||
$ cabal build all --dry-run | ||
... | ||
When using configuration from: | ||
- - dir-a/b.config | ||
- dir-a\b.config | ||
- cabal.project | ||
``` | ||
|
||
## Ord ProjectConfigPath Instance Changes | ||
|
||
For comparison purposes, path separators are normalized to the @buildOS@ | ||
platform's path separator. | ||
|
||
```haskell | ||
-- >>> let abFwd = ProjectConfigPath $ "a/b.config" :| [] | ||
-- >>> let abBwd = ProjectConfigPath $ "a\\b.config" :| [] | ||
-- >>> compare abFwd abBwd | ||
-- EQ | ||
