Duktape ======= [](https://github.com/svaarala/duktape/actions) [](https://github.com/svaarala/duktape/actions) [](https://ci.appveyor.com/project/svaarala/duktape) :warning: **Master branch is undergoing incompatible changes for Duktape 3.x**. To track Duktape 2.x, follow the `v2-maintenance` branch. Introduction ------------ [Duktape](http://duktape.org/) 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, with some semantics updated from ES2015+ * Partial support for ECMAScript 2015 (E6) and ECMAScript 2016 (E7), [Post-ES5 feature status](http://wiki.duktape.org/PostEs5Features.html), [kangax/compat-table](https://kangax.github.io/compat-table) * ES2015 TypedArray and Node.js Buffer bindings * WHATWG Encoding API living standard * 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 coroutines * Property virtualization using a subset of ECMAScript ES2015 Proxy object * Bytecode dump/load for caching compiled functions * Distributable includes an optional logging framework, CommonJS-based module loading implementations, CBOR bindings, etc * Liberal MIT license (see LICENSE.txt) See [duktape.org](http://duktape.org/) for packaged end-user downloads and documentation. The end user downloads are also available from the [duktape-releases](https://github.com/svaarala/duktape-releases) repo as both binaries and in unpacked form as git tags. Have fun! Support ------- * Duktape Wiki: [wiki.duktape.org](http://wiki.duktape.org) * User community Q&A: Stack Overflow [duktape](http://stackoverflow.com/questions/tagged/duktape) tag * Bugs and feature requests: [GitHub issues](https://github.com/svaarala/duktape/issues) * General discussion: IRC `#duktape` on `chat.freenode.net` ([webchat](https://webchat.freenode.net)) 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. Getting started: end user ------------------------- When embedding Duktape in your application you should use the packaged source distributables available from [duktape.org/download.html](http://duktape.org/download.html). See [duktape.org/guide.html#gettingstarted](http://duktape.org/guide.html#gettingstarted) for the basics. The distributable `src/` directory contains a `duk_config.h` configuration header and amalgamated sources for Duktape default configuration. If necessary, use `python tools/configure.py` to create header and sources for customized configuration options, see http://wiki.duktape.org/Configuring.html. For example, to enable fastint support (example for Linux): $ tar xvfJ duktape-2.0.0.tar.xz $ cd duktape-2.0.0 $ rm -rf src-custom $ python tools/configure.py \ --source-directory src-input \ --output-directory src-custom \ --config-metadata config \ -DDUK_USE_FASTINT # src-custom/ will now contain: duktape.c, duktape.h, duk_config.h. You can download and install duktape using the [vcpkg](https://github.com/Microsoft/vcpkg) dependency manager: $ git clone https://github.com/Microsoft/vcpkg.git $ cd vcpkg $ ./bootstrap-vcpkg.sh $ ./vcpkg integrate install $ vcpkg install duktape The duktape port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository. You can also clone this repository, make modifications, and build a source distributable on Linux, macOS, and Windows using `python util/dist.py`. You'll need Python 2 and Python YAML binding. Getting started: modifying and rebuilding the distributable ----------------------------------------------------------- If you intend to change Duktape internals and want to rebuild the source distributable in Linux, macOS, or Windows: # Linux; can often install from packages or using 'pip' $ sudo apt-get install python python-yaml $ python util/dist.py # macOS # Install Python 2.7.x $ pip install PyYAML $ python util/dist.py # Windows ; Install Python 2.7.x from python.org, and add it to PATH > pip install PyYAML > python util\dist.py The source distributable directory will be in `dist/`. For platform specific notes see http://wiki.duktape.org/DevelopmentSetup.html. 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**. See detailed instructions in http://wiki.duktape.org/DevelopmentSetup.html. There are some Docker images which can simplify the development setup. These are also **intended for Linux only**. For example: # Build Docker images. This takes a long time. $ make docker-images # Equivalent of 'make dist-source', but runs inside a container. $ make docker-dist-source-wd # Run a shell with /work/duktape containing a disposable master snapshot. $ make docker-shell-master # Run a shell with /work/duktape mounted from current directory. # This allows editing, building, testing, etc with an interactive # shell running in the container. $ make docker-shell-wdmount # For non-native images you may need: # https://github.com/multiarch/qemu-user-static Branch policy ------------- * The `master` branch is used for active development. Even though pull requests are tested before merging, master may still be broken from time to time. When development on a new major release starts, master will also get API incompatible changes without warning. For these reasons **you should generally not depend on the master branch** for building your project; use a release tag (e.g. `v2.4.0`) or a release maintenance branch (e.g. `v2.4-maintenance` or `v2-maintenance`) instead. * Pull requests and their related branches are frequently rebased so you should not fork off them. Pull requests may be open for a while for testing and discussion. * Release tags like `v1.4.1` are used for releases and match the released distributables. These are stable once the release is complete. * Maintenance branches are used for backporting fixes and features for maintenance releases. Documentation changes go to master for maintenance releases too. For example, `v1.5-maintenance` was created for the 1.5.0 release and is used for 1.5.x maintenance releases. * A maintenance branch is also created for a major release when master moves on to active development of the next major release. For example, `v1-maintenance` was created when 1.5.0 was released (last planned 1.x release) and development of 2.0.0 (with API incompatible changes) started on master. The 1.6.0 and 1.7.0 releases were made from `v1-maintenance` for example. Versioning ---------- Duktape uses [Semantic Versioning](http://semver.org/) for official releases. Builds from Duktape repo are not official releases and don't follow strict semver, mainly because `DUK_VERSION` needs to have some compromise value that won't be strictly semver conforming. Because Duktape tracks the latest ECMAScript specification versions, compliance fixes are made in minor versions even when they are technically not backwards compatible. See [Versioning](http://duktape.org/guide.html#versioning) for details. Reporting bugs -------------- See [CONTRIBUTING.md](https://github.com/svaarala/duktape/blob/master/CONTRIBUTING.md). Security critical GitHub issues (for example anything leading to a segfault) are tagged `security`.
