Duktape is an embeddable Javascript engine, with a focus on portability and compact footprint.

Duktape is easy to integrate into a C/C++ project: add duktape.c and duktape.h to your build, and use the Duktape API to call Ecmascript functions from C code and vice versa.

Main features:

• Embeddable, portable, compact
• Ecmascript E5/E5.1 compliant
• Built-in regular expression engine
• Built-in Unicode support
• Minimal platform dependencies
• Combined reference counting and mark-and-sweep garbage collection with finalization
• Liberal license

See duktape.org for packaged end-user downloads and documentation.

Have fun!

This repository is intended for Duktape developers only, and contains Duktape internals: test cases, internal documentation, sources for the duktape.org web site, etc.

When embedding Duktape in your application you should use the packaged source distributables available from duktape.org/download.html.

However, if you really want to use a bleeding edge version:

$ git clone https://github.com/svaarala/duktape.git
$ cd duktape
$ make dist-src

Then use duktape-<version>.tar.xz like a normal source distributable.

If you intend to change Duktape internals, run test cases, etc:

# Install NodeJS and npm
$ sudo apt-get install nodejs npm

# Compile the command line tool ('duk')
$ git clone https://github.com/svaarala/duktape.git
$ cd duktape
$ make

# Run Ecmascript and API testcases
$ make ecmatest
$ make apitest
$ make regfuzztest
$ make underscoretest    # see doc/underscore-status.txt
$ make test262test       # see doc/test262-status.txt
$ make emscriptentest    # see doc/emscripten-status.txt
$ make jsinterpretertest

Note: the repo Makefile is intended for Linux developer use, it is not a multi-platform "end user" Makefile. In particular, the Makefile is not intended to work on e.g. OSX or Windows. The source distributable has more user-friendly Makefile examples, but you should normally simply write your own Makefile when integrating Duktape into your program.
