SimpleSquish

SimpleSquish is a simple library for Lua 5.1 that wraps around Squish. It exposes the functionality of Squish without requiring a file system. Internally, SimpleSquish creates a virtual file system which enables us to feed Squish all necessary data as Lua strings instead of having to deal with creating squishy files for it, etc.

SimpleSquish is perfect if you, for example, just want to minify or obfuscate some Lua code as part of your program.

Usage
API
- Squish arguments

Usage

The files you need from this repository are simpleSquish.lua and squish.lua.

local squish = require("simpleSquish")

local lua = [[
	local x = 5 -- Hello.
	local function foo()
		print("World")
	end
]]

local minifiedLua = squish.minify(lua)
print(minifiedLua)

-- Output will be something like:
-- local a=5 local function b()print("World")end

See runTest.lua for more example code.

API

minify

squishedLua = squish.minify( lua [, minifyLevel="full", extraSquishArguments ] )

Apply minify on some Lua code. minifyLevel can be "none", "debug", "default", "basic" or "full". Shorthand for:

local args = {"--minify-level=full"}
local squishedLua = squish.squish(lua, args)

minifyAndUglify

squishedLua = squish.minifyAndUglify( lua [, minifyLevel="full", extraSquishArguments ] )

Apply minify and uglify on some Lua code. minifyLevel can be "none", "debug", "default", "basic" or "full". Shorthand for:

local args = {"--minify-level=full", "--uglify"}
local squishedLua = squish.squish(lua, args)

read

contents, error = squish.read( path [, isTextFile=false ] )

Read the entire contents of a file. Returns nil and a message on error.

squish

squishedLua = squish.squish( lua [, squishArguments ] )

Squish some Lua code.

squishPath

squish.squishPath = ""

The path to squish.lua. An empty string means SimpleSquish will try to load it from the same folder as SimpleSquish is in.

VERSION

squish.VERSION

The current version of SimpleSquish, e.g. "1.3.0".

write

success, error = squish.write( path, contents [, isTextFile=false ] )

Write to a file. Returns false and a message on error.
