sebmaynard / module_starter_hack.erl

Created June 6, 2013 13:54

A hack to try and startup an erlang application and its dependencies. Should only really be used for lazy development/fiddling as reltool/relx/rebar will handle all this for you.

	-export([try_force_start_application/1]).

	try_force_start_application(App) ->
	start_application_process_result(App, try_start_application(App)).

	-module(ca_cowboy_middleware).

	-behaviour(cowboy_middleware).

	-export([execute/2]).

	execute(Req, Env) ->
	{ok, ReqWithCorsHeaders} = set_cors_headers(Req),

sebmaynard / restore_dotfiles.sh

Created June 12, 2013 10:38

A bash script to restore dotfiles to ~/ from somewhere else (probably files under a git repository). Allows you to keep *some* of your dotfiles in git without needing everything, and a fast way to restore them on a new box.

	#!/bin/bash

	function link_files_to_folder() {
	if [[ ! -d $1 \|\| ! -d $2 ]] ; then
	echo "Usage: link_files_to_folder <source_dir> <target_dir> [prefix]"
	exit
	fi

	SOURCE_DIR=$1
	TARGET_DIR=$2

sebmaynard / owncloud-upgrade.sh

Created June 12, 2013 15:52

Upgrade an owncloud instance. Check the notes at the top for assumptions

	#!/bin/bash

	# Upgrade an owncloud instance. Makes the following assumptions:
	# 1. you're running this as the same user who owns (and can write to) $OWNCLOUD_FOLDER
	# 2. $TMP_FOLDER is writeable by this user

	# These should be absolute paths
	OWNCLOUD_FOLDER=/var/public_html_ssl/cloud
	TMP_FOLDER=/tmp/owncloud-upgrade

sebmaynard / emacsclient_gui.sh

Created June 14, 2013 08:43

Start emacsclient with some progress of what's going on (useful for desktop launchers)

	#!/bin/bash

	## for emacsclient:
	## -c is gui window
	## -n is no-wait - don't wait for the window to close
	## sed buffers by default
	## -u is unbuffered
	## zenity expects text progress to start with #
	emacsclient -c -n 2>&1 \| sed -u -e 's/^/# /g' \| zenity --title="Starting EmacsClient" --width=600 --progress --pulsate --auto-close

sebmaynard / .tmux.conf

Last active December 29, 2015 15:19

Enable ctrl-<arrow> keys for moving between tmux and emacs panes (requires emacs, tmux and zsh). This allows you to use ctrl-<arrow> to switch panes in an emacs split, and then move to the nearest tmux pane once you get to the edge of the emacs window. Particularly useful if you have tmux split with emacs in one pane, and zsh in another

set-window-option -g xterm-keys on

Last active August 29, 2015 14:01

	#!/bin/bash

	# speed things up quite a lot!
	export LC_ALL=C

	# uses -P (perl regular expressions) for speed
	find ./ -type f ! \
	-path "/deps/" ! \
	-path "/caerldeps/" ! \
	-path "/_rel/" ! \
