Duktape
Introduction
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
,
duktape.h
, and duk_config.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
- Khronos/ES6 TypedArray and Node.js Buffer bindings
- Built-in debugger
- Built-in regular expression engine
- Built-in Unicode support
- Minimal platform dependencies
- Combined reference counting and mark-and-sweep garbage collection with finalization
- Custom features like co-routines, built-in logging framework, and built-in CommonJS-based module loading framework
- Property virtualization using a subset of Ecmascript E6 Proxy object
- Bytecode dump/load for caching compiled functions
- Liberal license
See duktape.org for packaged end-user downloads and documentation. The end user downloads are also available from the duktape-releases repo as both binaries and in unpacked form as git tags. Snapshot builds from master are available in duktape.org/snapshots.
Have fun!

About this repository
This repository is intended for Duktape developers only, and contains Duktape internals: test cases, internal documentation, sources for the duktape.org web site, etc.
Current branch policy: the "master" branch is used for active development, other branches are frequently rebased feature branches (so you should not fork off them), and tags are used for releases. Master is quite stable, but may be broken from time to time so use it with care.
Getting started: end user
When embedding Duktape in your application you should use the packaged source distributables available from duktape.org/download.html. See duktape.org/guide.html#gettingstarted for the basics.
Automatically generated bleeding edge snapshots from master are available at duktape.org/snapshots.
You can also clone this repository, make modifications, and build a source
distributable on Linux, OSX, and Windows using python util/make_dist.py
.
Getting started: modifying and rebuilding the distributable
If you intend to change Duktape internals and want to rebuild the source distributable in Linux, OSX, or Windows:
# Linux; can often install from packages or using 'pip'
$ sudo apt-get install python python-yaml
$ python util/make_dist.py
# OSX
# Install Python 2.7.x
$ pip install PyYAML
$ python util/make_dist.py
# Windows
; Install Python 2.7.x from python.org, and add it to PATH
> pip install PyYAML
> python util\make_dist.py
The source distributable directory will be in dist/
.
Getting started: other development (Linux only)
Other development stuff, such as building the website and running test cases,
is based on a Makefile
intended for Linux only:
# Install required packages (exact packages depend on distribution)
$ sudo apt-get install nodejs nodejs-legacy npm perl ant openjdk-7-jdk \
libreadline6-dev libncurses-dev python-rdflib python-bs4 python-yaml \
clang llvm bc
# Compile the command line tool ('duk')
$ git clone https://github.com/svaarala/duktape.git
$ cd duktape
$ make
# If you want to build dukweb.js or run Emscripten targets, you need
# to setup Emscripten fastcomp manually, see doc/emscripten-status.rst
# for step-by-step instructions.
# Run Ecmascript and API testcases, and some other tests
$ make ecmatest
$ make apitest
$ make regfuzztest
$ make underscoretest # see doc/underscore-status.rst
$ make test262test # see doc/test262-status.rst
$ make emscriptentest # see doc/emscripten-status.rst
$ make emscriptenmandelbrottest # run Emscripten-compiled mandelbrot.c with Duktape
$ make emscripteninceptiontest # run Emscripten-compiled Duktape with Duktape
$ make jsinterpretertest
$ make luajstest
$ make dukwebtest # then browse to file:///tmp/dukweb-test/dukweb.html
$ make xmldoctest
$ make bluebirdtest
# etc
You may get the Makefile working in OSX or Windows (using Cygwin), but this is not supported at the moment.
