Short Python tips, sometimes with a Django bent, sometimes without unit tests.

	def _autofmthelper(name, fmt, postprocess=None):
	def fmtfunc(self):
	result = fmt.format(self=self)
	if postprocess is not None:
	result = postprocess(self, result)

wolever / profile

Created September 11, 2013 15:41

My very fast Bash prompt, which shows git branch, virtualenv, and background jobs

	# prompt examples:
	# [3 jobs master virtualenv] ~/code/myproject/foo
	# [1 job my-branch virtualenv] ~/code/bar/
	# [virtualenv] ~/code/
	# ~
	# Very, very fast, only requiring a couple of fork()s (and no forking at all to determine the current git branch)

	if [[ "$USER" == "root" ]]
	then
	export PS1="\e[1;31m\]\u \[\e[1;33m\]\w\[\e[0m\] ";

wolever / git-unpull

Last active December 21, 2015 04:08

git-unpull: undoes the merge commit created by an accidental 'git pull', plus some added helpful information!

	#!/bin/bash
	# Reverts HEAD back to ORIG_HEAD, for example after a 'git pull' accidentally
	# creates a merge. This is identical to running 'git reset --hard ORIG_HEAD',
	# except that unpull prints some helpful information along the way.
	# Useage:
	# $ git unpull
	# HEAD: a0ac0fd Merge branch 'master' of /tmp/foo
	# 2284c9d some remote commit
	# ORIG_HEAD: 35431fd my local commit
	# Really reset HEAD to ORIG_HEAD? (y/n) y
