NOTE: This is a question I found on StackOverflow which I’ve archived here, because the answer is so effing phenomenal.

Q: How can I make a chain of function decorators in Python?

If you are not into long explanations, see [Paolo Bergantino’s answer][2].

Pure SASS-adaption of Lea Verou's contrast-ratio javascript. Can be useful when eg. generating colored buttons from a single supplied color as you can then check which out of a couple of text colors would give the best contrast.

This script currently lacks the support for alpha-transparency that Lea supports in her script though.

In addition to the color-contrast adaption there's also some math methods that were needed to be able to calculate the exponent of a number and especially so when the exponent is a decimal number. A 2.4 exponent is used to calculate the luminance of a color and calculating such a thing is not something that SASS supports out of the box and not something I found a good pure-SASS script for calculating and I much prefer pure-SASS over ruby extensions. The math methods might perhaps be unecessary though if you're running Compass or similar as they may provide compatible math methods themselves.

Normal usage: `color: pick_best_color(#f00

The standard names for indexes in PostgreSQL are:

{tablename}_{columnname(s)}_{suffix}

where the suffix is one of the following:

• pkey for a Primary Key constraint;
• key for a Unique constraint;
• excl for an Exclusion constraint;
• idx for any other kind of index;
