Type of a function that creates new empty directory on the given path.

Type of a function that returns True if the argument file exists and is not a directory, and False otherwise.

Type of a function that recursively finds files on given path whose filename matches the predicate.

Type of a function that recursively finds files on given path by file extensions.

Type of a function that recursively find files on given path by their file types.

Type of a function that obtains the current working directory as an absolute path.

Type of a function that recursively find all files on given path. If file reference is passed instead of directory, such file path is returned.

Type of a function that loads file content in UTF8 encoding.

Polymorphic record composed of file system IO function types, allowing to abstract over concrete implementation. Whenever you need to use effectful functions from this module, consider using this record instead of using them directly, as it allows you to use different records for production code and for testing, which is not as easy if you wire some of the provided functions directly.

Creates new FileSystem that performs actual disk IO operations.

Recursively finds files on given path whose filename matches the predicate.

Recursively finds files on given path by file extensions.

Recursively find files on given path by their file types.

Recursively find all files on given path. If file reference is passed instead of directory, such file path is returned.

Loads file content in UTF8 encoding.

Returns file extension for given path (if file), or nothing otherwise.

>>> fileExtension "path/to/some/file.txt"
Just "txt"

Takes list of patterns and file paths and returns list of file paths where those matching the given patterns are excluded.

>>> :set -XQuasiQuotes
>>> import Headroom.Data.Regex (re)
>>> excludePaths [[re|\.hidden|], [re|zzz|]] ["foo/.hidden", "test/bar", "x/zzz/e"]
["test/bar"]
