catty v0.1.0

Catty

Catty is the source file concatenator for Mapshaper.

Some features:

• Each source file lists its dependencies in a formatted comment (see below). There is no manifest, unlike some other tools.
• Concatenated files are (optionally) wrapped in a self-executing function, to protect the global namespace.
• Catty can monitor source files and regenerate output files when a required source file changes.

Command line tool

Usage: $ catty [options] input output

Options:

• -f Monitor source files, re-cat when something changes.
• -g Don't wrap source files in an immediate function.
• -d Comma-separated list of directories to monitor
• -h Print help message

Example: $ catty -g -d src,lib src/input.js dist/output.js

Node module

Example

require('catty')({global: true})
	.addLibrary('src')
	.addLibrary('lib')
	.cat('src/input.js', 'dist/output.js');

Methods

#cat(input, output) Concatenate an input file with its dependencies. output may be a filename or a Node-style callback. If output is empty or contains a hyphen, catty sends its output to stdout.

#addLibrary(dir) Give catty a directory to search for dependencies.

#prepend(JS) Insert JavaScript before concatenated code.

#addDeps(deps) Inject one or more additional dependencies into the input file (comma-sep. list).
