Filters

Parse the symbolic links

realpath: os.path.realpath
readlink: os.readlink
abspath: os.path.abspath

Find common prefix of given paths

commonprefix:
>>> commonprefix("/a/b/abc.txt", "/a/b/abc.png")
>>> # "abc."
>>> commonprefix("/a/b/abc.txt", "/a/b/abc.png", basename_only=False)
>>> # "/a/b/abc."

Get parts of the path

dirname: path.dirname
basename: path.basename
ext, suffix: get the extension (/a/b/c.txt -> .txt)
ext0, suffix0: get the extension without dot (/a/b/c.txt -> txt)
prefix: get the prefix of a path (/a/b/c.d.txt -> /a/b/c.d)
prefix0: get the prefix of a path without dot in basename (/a/b/c.d.txt -> /a/b/c)
filename, fn, stem: get the stem of a path (/a/b.c.txt -> b.c)
filename0, fn0, stem0: get the stem of a path without dot (/a/b.c.txt -> b)
joinpaths, joinpath: join path parts (os.path.join)
as_path: convert a string into a pathlib.Path object

Path stat

isdir: os.path.isdir
isfile: os.path.isfile
islink: os.path.islink
exists: os.path.exists
getsize: os.path.getsize, return -1 if the path doesn't exist
getmtime: os.path.getmtime, return -1 if the path doesn't exist
getctime: os.path.getctime, return -1 if the path doesn't exist
getatime: os.path.getatime, return -1 if the path doesn't exist
isempty: check if a file is empty

Quote data

quote: put double quotes around data (1 -> "1")
squote: put single quotes around data (1 -> '1')

Configurations

json, json_dumps: json.dumps
json_load: Load json from a file
json_loads: json.loads
toml: toml.dumps
toml_dump: Load toml from a file
toml_dumps: Alias of toml
toml_loads: toml.loads
config: Load configuration from an object, a string or a file

Globs

glob: Like glob.glob, but allows passing multiple parts of a path
glob0: Like glob, but only returns the first matched path

Read file contents

read: Read file content. You can also pass arguments to open
readlines: Read file content as a list of lines. Additional arguments will be passed to open
