Plask is a programming environment for multimedia and computational design.

- Getting Plask

For the common user, it is best to use the binary distribution provided at  If you're interested in building and running from source, the
following section should help you get started.

- Building and running from source

Plask integrates together quite a few pieces of technology, which unfortunately
makes the build process more complicated.  It is possible to do a boostrapped
build, where you only build the Plask source file, but use prebuilt object
files for Plask's dependencies.  Run the script to download and
extract a copy of these prebuilt dependencies.  When fetching new source
changes to Plask, you will have to be aware if there have been any changes to
the prebuilt dependencies, and if so, to run again.

For example, to build from a completely new checkout would look something like:

  $ sh
  $ xcodebuild -project plask.xcodeproj -configuration Release -target Plask

This should produce  For some technical and design reasons,
is effectively a commandline application inside a bundle.  For example, running on the command line will start a Node-style REPL
loop, an interactive JavaScript shell of sorts.

Pass a filename on the command line to run that JavaScript file.

NOTE: To ease development, the built has a symlink to plask.js in
the source.  This allows you to edit plask.js in the source repository without
having to rebuild the project.

A separate project, PlaskLauncher, creates the UI application for launching
Plask by dragging/dropping or File->Open.

- Creating standalone applications

When is launched, it will look for a file named main.js inside of
the bundle (in Contents/Resources).  This allows you to easily create
standalone applications by copying and putting your JavaScript source
inside of the bundle.

NOTE: When running "bundled", the current working directory will likely be
different from running Plask on the command line.  Generally this means if you
open files you should open a path relative to __dirname, which is Node's global
variable for the directory that your JavaScript file is in.
