Mint

Minimalist templating.

fs = require 'fs'
coffee = require 'coffee-script'

The render method returns a template from template text or an interpolated template if passed a data object. Ex:

Factory Pattern

Trevor Burnham's example.

class Enterprise 
constructor: (@captain) ->
 @name = @constructor.name

Callable Classes

A quick little hack to make a class callable.

Note that this is generally inadvisable and can be avoided altogether by assigning the target class method to a function.

Hack

Rename

Rename files with regular expressions. A filename fixer utility courtesy of Larry Wall.

Usage

rename expr [files]

Examples

Header Testing

List files containing PATTERN in first line of a file:

perl -ne'print "$ARGV\n" if /PATTERN/; close ARGV' *.txt

List files not containing PATTERN in first line of a file:

perl -ne'print "$ARGV\n" unless /PATTERN/; close ARGV' *.txt

Sift files by header

Suppose you have a set of files you want to partition on the basis of the first line in the file.

This script enables you to move a filtered subset (based on the header line) to a target directory.

You specify the pattern in the first line of the files you wish to move. Those files containing the pattern in their header get moved, those without don't.

	{test, ok, arrayEq} = require 'testy'


	Array::uniq = ->
	U = {}
	U[@[i]] = @[i] for i in [0...@length]
	v for k, v of U

	flatten = (arr) -> arr.reduce ((x, y) -> x.concat y), []

	import sys
	sys.path.insert(0, '..') # relative path to MODULE, change as appropriate
	from MODULE import * # replace MODULE with the name of your module
