jbarber / redmine.pl

Created December 18, 2013 17:01

Simple example of hacking the redmine issue tracker via it's API

	#!/usr/bin/env perl

	# This script provides a basis for futzing about with redmine via it's API
	# You will also need to refer to TFM at:
	# http://www.redmine.org/projects/redmine/wiki/Rest_Issues
	# to fully learn how to manipulate the system.
	# It's my impression from the Redmine bugtrackker that there seem to be plenty
	# of bugs in the Redmine API implimentation, and that the implimentation
	# doesn't cover everything you can do via the GUI.

jbarber / timer.go

Created July 7, 2014 21:54

Go routine on a changable timer

	package main

	/*
	Example of creating go routine with time based channel - this time can be
	adjusted by the parent, so it can postpone (or bring forwards) whatever the
	child should do. This could be useful for creating a polling mechanism which
	you occasionally want to run sooner.

	The parent creates the channel and passes it to the go routine to wait for 10
	seconds. This channel is used to communicate how long the child should wait

jbarber / xml-parse.go
