Python library to colorize filenames in a terminal based on their type
pydircolors - color filenames for terminal display
Do you like file/directory listings in your terminal to be colorized? Do you like how GNU coreutils'
ls command does it? Want to incorporate that functionality into a Python application? Then
pydircolors is the library for you!
This library is currently in Alpha development stage, but I'm getting close to an initial release.
pydircolors is intended for console use on POSIX-like systems. It's developed on Linux, but should
work in any terminal that supports xterm-style 16 color escape sequences and environments with
stat() syscalls. Notably,
cmd.exe terminals on native Windows are not
supported, but Cygwin works.
pydircolors requires Python 3.3 or newer. The main limitation is that the
follow_symlinks keyword args to
are used, which were added in Python 3.3. It'd be possible to add support for older versions
(including Python 2.7) with compatibility shims. If you ask nicely, I'll a) be overjoyed that
someone's actually using this library, and b) will consider adding that functionality.
Distributions are built using flit and PEP 517 rather than setuptools (setup.py). Installing from PyPi using pip works as usual, flit is only needed for building sdists and wheels from git source.
Install with pip:
pip install dircolors
Install from source (should be used in a venv, don't run pip as root):
flit install pip install . # requires pip >= 19.0
Install from source in editable development mode (should be used in a venv):
flit install -s
On Arch Linux and its derivatives, you can install the python-dircolors AUR package.
This repo contains a makefile as a convenience that wraps some common development tasks. Possible make targets are:
test(the default): run unit tests
venv: set up a new python3 venv in the 'venv' directory and install an up-to-date pip, ipython, and everything from requirements-dev.txt (including flit). You should run
make venvto enter the venv.
lint: run pylint
dist: build distribution sdist and wheel with flit
clean: remove built dist packages and all __pycache__ files
distclean: clean, plus remove the entire venv
Start by creating a
Dircolors object and calling its
format() method with the filename you want
import dircolors dc = dircolors.Dircolors() print(dc.format('README.md')) print(dc.format('dist/pydircolors.tar.gz') print(dc.format('pydircolors.tar.gz', cwd='dist'))
As seen above, the
cwd keyword argument looks for the filename relative to that directory.
can be a string of the directory name, or an integer directory descriptor returned by
Symlinks are intelligently supported too. Set
follow_symlinks=True to follow links and format the
link name like its target file. Set
follow_symlinks=False (the default) and
print the link name, colored like a link, an ASCII arrow (
->), and the link target, formatted
>>> print(dc.format('a_link', show_target=True)) a_link -> link_target
If you've already run
os.stat() on a file, you can re-use the result to avoid extra syscall
overhead with the
format_mode() accepts arbitrary text to format (which
need not actually be the filename) and the file mode, which can be an
os.stat_result object (as
os.stat() or an integer of representing the
stat_result = os.stat('some_file') print(dc.format_mode('some_file', stat_result)) print(dc.format_mode('a_link', 0o0120777))
Dircolors database sources
Dircolors objects load from the
LS_COLORS environment variable, just like GNU
A variety of functions to load from custom
LS_COLORS strings or
.dircolors files are available
as well. All load functions will clear the currently loaded database, even if they fail to load any
dc.load_from_environ() # load from the LS_COLORS environment variable (the default) dc.load_from_environ(env_var_name) # load from a different environment variable dc.load_from_lscolors('rs=0:di=01;34:') # load from an LS_COLORS string dc.load_defaults() # use the defaults as generated by `dircolors -p` dc.load_from_dircolors('.dircolors') # load from a dircolors filename dc.load_from_dircolors(open_file_obj) # load from an open file-like object

Items needed for a v0.1.0 release:
- Clean up
pylsand add some argparse support. Also document it here.
- Add tests for the color formatting functionality rather than just loading data.
- Upload to PyPi
Items needed for a v1.0.0 release:
- Sphinx documentation
- Commit to a stable API
