FilePathsBase.jl

Build Status codecov.io Code Style: Blue

FilePathsBase.jl provides a type based approach to working with filesystem paths in julia.

Intallation

FilePathsBase.jl is registered, so you can to use Pkg.add to install it.

julia> Pkg.add("FilePathsBase")

Getting Started

Here are some common operations that you may want to perform with file paths.

#=
NOTE: We're loading our `/` operator for path concatenation into the currect scope, but non-path division operations will still fallback to the base behaviour.
