Simple example of using doctests to test small functions within a module
#! /usr/bin/python3
def tupleise(*values):
"""
Return a tuple based on the arguments - if there are none then return an
empty tuple or if there are more than one create and return a new tuple from
the arguments. If there is one arg, if it is iterable but not a string then
create a tuple from its items, otherwise return tuple with a single-element
equal to that argument.

A small-ish module for doing string interpolation, variable substitution and simple transforms for when you don't want a full-blown templating system

spiralx / classof.js
Last active February 17, 2017 12:00
An accurate function for getting the type of a variable in JavaScript, using the fact that Object.prototype.toString() is guaranteed to return an object's internal [[Class]] property when called on it. There's also the isclass() helper function that takes an object and one or more class name strings, and returns True if the class of obj matches …
/**
* classof(obj)
*
* Returns the object's internal [[Class]] property, see
* the other file for example output.
*
* @param {Object?} object
* @return {String}
*/
const classof = v => Object.prototype.toString.call(v).replace(/^\[object\s(.*)\]$/, '$1').toLowerCase();

Regular Expressions with Named Groups
/**
* Allows you to specify named groups in regular expressions like in Perl/Python/.NET/etc. You have to
* use a string to specify the regex, and the function returns an object that has `exec` and `replace`
* functions like a normal RegExp object, but matches they generate have keys for the values of the named
* groups.
*
* n = NamedRegExp("(?<protocol>http|ftp)://(?<host>[\\w-]+\\.com)(?<path>/.+\\.html)?$");
* res = n.exec("http://foobar.com"); -> res.protocol = http, res.host = foobar.com res.path = undefined
* res = n.exec("http://foobar.com/"); -> res.protocol = http, res.host = foobar.com res.path = /
