ubernostrum / webcolors Goto Github PK

This seems to have been introduced when upgrading from 1.7.0 to 1.8.0.

Installing via pip is giving the following error:

AssertionError: webcolors .dist-info direction not found

I've locked the version on my end to 1.7.0, so it works.

Here's details about my environment if that helps:

pip: 9.0.1
python: 3.5.1

While the project seems to use type annotations internally, type checkers will ignore them because the py.typed marker file is missing. Note that adding the file will not be enough, since you will also need to explicitly add py.typed to the package_data so the py.typed marker is still there after installation.

I read through the documentation but couldn't find any function which simply allows throwing in any css color attribute and getting back RGB information.

styles = {'color': 'hotpink', 'background-color': '#C0FFEE'}

webcolors.parse(styles['color'])
webcolors.parse(styles['background-color'])

Hi,

I've recently used this module to get the name of an RGB color, but was only interested in getting generic names (like the group names from here). I needed to write a dictionary for converting from color name to color group.

What about extending the functionality of get_colour_name by adding a group flag? If needed, I could totally help with that.

Best,
Cosmina

rebeccapurple (#663399) is a named color added in CSS Color Module Level 4 to honor web pioneer Eric Meyer. Although Level 4 is not a formal W3C Recommendation & rebeccapurple is not in the SVG 1.1 spec, it is a Candidate Recommendation Draft and all browsers have supported this value since 2015. Therefore, this color should probably be added, and tests/definitions.py should migrate to Level 4.

I have a Raspberry Pi with Raspbian and Python 3.2.3. When I attempt to install Webcolors with pip, or manually download the tar.gz and run the install script, I get the following error:

Any ideas?

Hi there! And thanks for this useful library!

I'm using this with pycollada, which wants RGB values as arrays of three floats from 0.0 to 1.0.

Would you be interested in a pull request to a function for exposing color values as rgb floats?

As we all know, today more than ever before, it is crucial to be able to trust our computing environments. One of the main difficulties that package maintainers of GNU/Linux distributions face, is the difficulty to verify the authenticity and the integrity of the source code. With GPG signatures it is possible for packagers to verify source code releases quickly and easily.

Overview of the required tasks:

• Create and/or use a 4096-bit RSA keypair for the file signing
• Use a strong, unique, secret passphrase for the key
• Upload the public key to a key server and publish the full fingerprint
• Sign every new Git commit and tag
• Create signed, compressed (xz --best) release archives
• Upload a strong message digest (sha512) of the archive
• Configure HTTPS for your download server

GPGit

GPGit is meant to bring GPG to the masses. It is not only a Python script that automates the process of creating new signed Git releases with GPG, but also a quick-start-guide for learning how to use GPG. GPGit integrates perfectly with the Github Release API for uploading.

The security status of GNU/Linux projects will be tracked in the Linux Security Database. If you have any further questions, do not hesitate to contact me personally. Thanks for your help in making GNU/Linux projects more secure by using GPG signatures.

Thanks in advance.

Would be excellent if the library included a function that accepted any of the color representations allowed in a CSS file, and normalized that to e.g. RGBA.

While webcolors has typing annotations in the code (which is amazing!), unfortunately those annotation can't be used by mypy to actually check the code against those annotations.

$ cat test.py
import webcolors

$ mypy test.py
test.py:1: error: Skipping analyzing 'webcolors': found module but no type hints or library stubs

The reason for that is webcolors get installed as site-packages/webcolors.py, but for mypy to be able to use the typing annotations in the code, it should be installed as site-packages/webcolors/__init__.py, with empty site-packages/webcolors/py.typed file present.

See https://mypy.readthedocs.io/en/stable/installed_packages.html for details.

Love the library and use it regularly for my projects!
It would be cool if there was the conversion to and from RGBA.
A in RGBA stands for Alpha and basically represents the opacity for each pixel (in %).
Perhaps it's possible to use the existing methods to convert the last 2 characters in 8 character HEX string into Alpha %.

I would like to know how many colors does webcolors provide?

Thanks in advance
