Count lines number in files

By combining the power of git and bash, we can have in an instant an estimation of lines number in a project.

For instance to count lines number in versionned perl files:

$ git ls-files | egrep ".*(driver|core).*pl$" | xargs wc -l

git ls-files will only return files versionned which is a first interesting filter.

Git Configuration

I put this configuration on every machine I work on in ~/.gitconfig.

It set the global scope ; equivalent to git config --global <key> <value>.

[user]
	name = jeandat
	email = [email protected]

A nice way to edit an iOS plist file from the shell

Source

#!/bin/bash

if [[ ! -f /usr/libexec/PlistBuddy ]]; then
    exit 0
fi

ExtendedDefinePlugin will replace ENV variables by their configuration value. Uglify will remove dead code.

1. Copy and modify `webpack.config.js`

// EDIT by Jean DAT
// Custom code in order to load different configuration files based on context (targeted environment).
// In a configuration file, I store things like the API url to use, etc.
var ExtendedDefinePlugin = require('extended-define-webpack-plugin');

PRE / POST Hook for Bash Prompt

Explained here.

AT_PROMPT=1 
# This will run before any command is executed.
function PreCommand() {
  if [ -z "$AT_PROMPT" ]; then
 return

function parse_git_branch () {
       git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}

GREEN="\[\033[0;32m\]"
YELLOW="\[\033[0;33m\]"
