Practical Coding Tips

A short list of language independent tips to make your coding life easier. And that of everyone working with you.

Every tip is meant to be just that: a tip. This is neither a rule book nor a style guide.

If you disagree with something, that's fine.

# @param ... - directories to pull (optional)
pull_all()

	# don't quote @ because it will prevent globbing

Manage subtrees manually

A lean approach to managing git subtrees [manually][mastering-subtrees]. Because git-subtree clutters the history graph and [git-stree][stree] still does too much for me.

I wanted the simplest possible solution that does not require anything special and that does not modify a repository beyond what's required for the most basic approach.

Skeletons

Create new projects from project skeletons.

This script is for you if you create nontrivial projects that can be derived from a common base.

Sample

markusfisch

#!/usr/bin/env bash

# Read lines from stdin and echo them if the indent is too deep
#
# @param 1 - levels of indent to consider too much (optional)
# @param 2 - indent character (optional)
check_indents()
{
	local THRESHOLD=${1:-3}
	local INDENT=${2:-$'\t'}

markusfisch

#!/usr/bin/env bash

# Copy difference only
#
# @param 1 - input path to base version
# @param 2 - input path to extended version
# @param 3 - output path of diff-only version
cpdiff()
{
	(( $# < 3 )) && {

Generate Android drawables from SVGs

BASH script to generate and update Android drawable/mipmap resources from SVG sources.

Requires either [Inkscape][inkscape] or [Image Magick][im] for conversion.
