io.js


This repository began as a GitHub fork of joyent/node.

io.js contributions, releases, and contributorship are under an open governance model. We intend to land, with increasing regularity, releases which are compatible with the npm ecosystem that has been built to date for Node.js.

Is it io.js or IO.js or iojs or IOjs or iOjS?

The official name is io.js, which should never be capitalized, especially not at the start of a sentence, unless it is being displayed in a location that is customarily all-caps (such as the title of man pages).

To build:

Unix / Macintosh

Prerequisites:

• gcc and g++ 4.8 or newer, or
• clang and clang++ 3.3 or newer
• Python 2.6 or 2.7
• GNU Make 3.81 or newer
• libexecinfo (FreeBSD and OpenBSD only)

$ ./configure
$ make
$ make install

If your Python binary is in a non-standard location or has a non-standard name, run the following instead:

$ export PYTHON=/path/to/python
$ $PYTHON ./configure
$ make
$ make install

To run the tests:

$ make test

To build the documentation:

$ make doc

To read the documentation:

$ man doc/iojs.1

Windows

Prerequisites:

• Python 2.6 or 2.7
• Visual Studio 2013 for Windows Desktop, or
• Visual Studio Express 2013 for Windows Desktop
• Basic Unix tools required for some tests, Git for Windows includes Git Bash and tools which can be included in the global PATH.

> vcbuild nosign

To run the tests:

> vcbuild test

Intl (ECMA-402) support:

Intl support is not enabled by default.

"small" (English only) support

This option will build with "small" (English only) support, but the full Intl (ECMA-402) APIs. With --download=all it will download the ICU library as needed.

Unix / Macintosh:

$ ./configure --with-intl=small-icu --download=all

Windows:

> vcbuild small-icu download-all

The small-icu mode builds with English-only data. You can add full data at runtime.

Note: more docs are on the joyent/node wiki.

Build with full ICU support (all locales supported by ICU):

With the --download=all, this may download ICU if you don't have an ICU in deps/icu.

Unix / Macintosh:

$ ./configure --with-intl=full-icu --download=all

Windows:

> vcbuild full-icu download-all

Build with no Intl support :-(

The Intl object will not be available. This is the default at present, so this option is not normally needed.

Unix / Macintosh:

$ ./configure --with-intl=none

Windows:

> vcbuild intl-none

Use existing installed ICU (Unix / Macintosh only):

$ pkg-config --modversion icu-i18n && ./configure --with-intl=system-icu

Build with a specific ICU:

You can find other ICU releases at the ICU homepage. Download the file named something like icu4c-**##.#**-src.tgz (or .zip).

Unix / Macintosh

# from an already-unpacked ICU:
$ ./configure --with-intl=[small-icu,full-icu] --with-icu-source=/path/to/icu

# from a local ICU tarball
$ ./configure --with-intl=[small-icu,full-icu] --with-icu-source=/path/to/icu.tgz

# from a tarball URL
$ ./configure --with-intl=full-icu --with-icu-source=http://url/to/icu.tgz

Windows

First unpack latest ICU to deps/icu icu4c-##.#-src.tgz (or .zip) as deps/icu (You'll have: deps/icu/source/...)

> vcbuild full-icu
