It's quite common to see web pages that show a solid color in place of images, while resources are being loaded. The color is usually averaged from the original image, as to give it a more "consistent" feeling while the page loads.
A simple way to do this from the command line is by using ImageMagick to resize the image to 1x1 size, then get the color of that one pixel:
% convert pic.jpg -resize '1x1!' txt:- # ImageMagick pixel enumeration: 1,1,65535,srgb 0,0: (16818.3,27417.8,39342.8) #416B99 srgb(65,107,153)
(The image ...
I recently ended up with a function that looks a bit like this (most of the logic was removed for sake of example):
def build(record, **kwargs): # Pretend we're doing stuff with the **kwargs here.. return record(**kwargs)
Where record could be one of several classes. All we care about is, the function accepts a type as first argument, and returns an instance of that type.
At first, the most logical way to describe this to mypy was to use a TypeVar like this:
from typing import Any, TypeVar, Type T = TypeVar('T') def build(record: Type ...
I am currently working on a mix of Python2/Python3 projects, and as such, I need to find a way to customize a few things on a per-project basis. This post contains notes I'm going to take along the path.
Using .dir-locals.el, you can customize things on a per-directory basis. Changes will affect all files in the directory containing this file, and all its subdirectories.
Note: you can use the M-x add-dir-local-variable command to quickly setup dir-locals. You'll be prompted to provide all the required information.
Set the flycheck-python-flake8-executable variable to the ...
I recently wrote a post about using py.test and tox. Now I improved the technique a bit, so here it is a new post with all the recent improvements.
(Please refer to that post for the problems I had to solve, and reasons behind the need of this kind of customizations).
In order to properly support Python3, I'm using this test class in my setup.py:
from setuptools.command.test import test as TestCommand
class PyTest(TestCommand):
test_package_name = 'MyMainPackage'
def finalize_options(self):
TestCommand.finalize_options(self)
_test_args = [
'--verbose',
'--ignore=build',
'--cov={0}'.format(self.test_package_name ...
I needed a library to extract metadata and plaintext transcript from various file formats, for indexing purposes.
After looking around for a while, I found out that Apache Tika might be the right tool for the job (or, at least, it does quite a good job in extracting information from files).
Sadly though, that thing is written in Java.
At first, I tried it by running the jar via subprocess and then parsing the json output. I quickly discarded that approach, as:
