OpenStack Style Guidelines

OpenStack has a set of style guidelines for clarity. OpenStack is a very large code base (over 1 Million lines of python), spanning dozens of git trees, with over a thousand developers contributing every 12 months. As such common style helps developers understand code in reviews, move between projects smoothly, and overall make the code more maintainable.

Which Shell to Use

Bash is the only shell scripting language permitted for executables.

Executables must start with #!/bin/bash and a minimum number of flags. Use set to set shell options so that calling your script as bash <script_name> does not break its functionality.

	// Provide string-matching based on fnmatch.3
	package fnmatch

	// There are a few issues that I believe to be bugs, but this implementation is
	// based as closely as possible on BSD fnmatch. These bugs are present in the
	// source of BSD fnmatch, and so are replicated here. The issues are as follows:
	//
	// * FNM_PERIOD is no longer observed after the first * in a pattern
	// This only applies to matches done with FNM_PATHNAME as well
	// * FNM_PERIOD doesn't apply to ranges. According to the documentation,

	function preventBackspace() {
	function matchesSelector_(el, selector) {
	return (el.matches \|\| el.msMatchesSelector).call(el, selector);
	}
	function prevent(e) {
	if (e.which === 8) { // Backspace
	if (!matchesSelector_(e.target, 'input:not([readonly]):not([type=radio]):not([type=checkbox]), textarea, [contentEditable], [contentEditable=true]')) {
	e.preventDefault();
	}
	}
