Fish like shell path in zsh.

	# shorten path -> /home/miekg/bla -> /h/m/bla
	function shorten() {
	full=$(print -P "$1")
	a=(${(s:/:)full})
	if [[ $#a -eq 0 \|\| $#a -eq 1 ]]; then
	print $1; return
	fi
	last=$a[$#a]
	a[$#a]= # clear last element
	for i in $a; do

	# In earlier versions of this makefile, the other two directories were
	# subdirectories of $(TZDIR). However, this led to configuration errors.
	# For example, with posix_right under the earlier scheme,
	# TZ='right/Australia/Adelaide' got you localtime with leap seconds,
	# but gmtime without leap seconds, which led to problems with applications
	# like sendmail that subtract gmtime from localtime.
	# Therefore, the other two directories are now siblings of $(TZDIR).
	# You must replace all of $(TZDIR) to switch from not using leap seconds
	# to using them, or vice versa.

miekg / zsh make function for golang

When doing cgo I get confused when to type make (to compile C code) or when to type go build (to compile Go code). Also in Vim you use :make, so to stop any confusing I'm using the following function. This allows me to always use 'make'.

	make() {
	if [[ -f Makefile \|\| -f GNUMakefile ]]; then
	command make "$@"
	return
	fi
	go build
	# if go build failed with exit code 1, the build env wasn't
	# correct, in that case, try make again
	if [[ $? -eq 1 ]]; then
	command make "$@"
