Fork chrisdone's path library I wasn't happy with the way it dealt with Dir vs File things. In his version of the library, a `Path b Dir` always ends with a trailing path separator and `Path b File` never ends with a trailing path separator. IMO, it is nonsensical to make a Dir vs File distinction on path level, although it first seems nice. Some of the reasons are: * a path is just that: a path. It is completely disconnected from IO level and even if a `Dir`/`File` type theoretically allows us to say "this path ought to point to a file", there is literally zero guarantee that it will hold true at runtime. So this basically gives a false feeling of a type-safe file distinction. * it's imprecise about Dir vs File distinction, which makes it even worse, because a directory is also a file (just not a regular file). Add symlinks to that and the confusion is complete. * it makes the API oddly complicated for use cases where we basically don't care (yet) whether something turns out to be a directory or not Still, it comes also with a few perks: * it simplifies some functions, because they now have guarantees whether a path ends in a trailing path separator or not * it may be safer for interaction with other library functions, which behave differently depending on a trailing path separator (like probably shelly) Not limited to, but also in order to fix my remarks without breaking any benefits, I did: * rename the `Dir`/`File` types to `TPS`/`NoTPS`, so it's clear we are only giving information about trailing path separators and not actual file types we don't know about yet * add a `MaybeTPS` type, which does not mess with trailing path separators and also gives no guarantees about them... then added `toNoTPS` and `toTPS` to allow type-safe conversion * make some functions accept more general types, so we don't unnecessarily force paths with trailing separators for `(</>)` for example... instead these functions now examine the paths to still have correct behavior. This is really minor overhead. You might say now "but then I can append filepath to filepath". Well, as I said... we don't know whether it's a "filepath" at all. * merge `filename` and `dirname` into `basename` and make `parent` be `dirname`, so the function names match the name of the POSIX ones, which do (almost) the same... * fix a bug in `basename` (formerly `dirname`) which broke the type guarantees * add a pattern synonym for easier pattern matching without exporting the internal Path constructor
