[Bf-docboard] Script to find out, how much has been translated

[Anton Felix Lorenzen]

Hi all,

I have made a small bash script, that shows, how much has already been
translated (~1% for German). It works on Linux, maybe Mac OS X, but not
on Windows (unless you use cygwin) and is quite slow.

Maybe you'll find it useful anyway.

Sincerely,
Anton Felix Lorenzen

PS: @Libellul: If I find time in the next days, I may add a search for
fuzzy tags, which would show outdated translations.

Script:

#!/bin/bash

# Usage: Copy it into the LC_MESSAGES directory,
# make it executable (chmod +x),
# and run it with a double-click
# First terminal argument specifies the name of the output file.

# Author: Anton Felix Lorenzen
# Purpose: Show, how much of a translation is already done

function outFile {
	out="generated-translations-list.txt"
	if [ -n "$1" ]; then
		out=$1
		echo $1
	fi
	echo $out
}

# Overwrites a file
function overwrite {
	echo "" > $1
}

# The file to write the result to
out=`outFile $1`
overwrite $out

# Write a string to $out
function say {
	echo $1 >> $out
}

# Get a list of all the .po-files within a directory
function getFiles {
	tree -f | grep "\.po" | sed -r "s/^[\│\ \ \─\├\└]+//"
}

	# At the start of each file are two fake lines
	# for editor information, we don't count them
