This repository began as a GitHub fork of
[joyent/node](https://github.com/joyent/node).

io.js contributions, releases, and contributorship are under an
[open governance model](./GOVERNANCE.md).
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)

```text
$ ./configure
$ make
$ [sudo] make install
```

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

```text
$ export PYTHON=/path/to/python
$ $PYTHON ./configure
$ make
$ [sudo] make install
```

To run the tests:

```text
$ make test
```

To build the documentation:

```text
$ make doc
```

To read the documentation:

```text
$ man doc/iojs.1
```

### Windows

Prerequisites:

* [Python 2.6 or 2.7](https://www.python.org/downloads/)
* Visual Studio 2013 for Windows Desktop, or
* Visual Studio Express 2013 for Windows Desktop
* Basic Unix tools required for some tests,
  [Git for Windows](http://git-scm.com/download/win) includes Git Bash
  and tools which can be included in the global `PATH`.

```text
> vcbuild nosign
```

To run the tests:

```text
> vcbuild test
```

### `Intl` (ECMA-402) support:

[Intl](https://github.com/joyent/node/wiki/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:

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

Windows:

```text
> 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](https://github.com/joyent/node/wiki/Intl).

#### 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:

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

Windows:

```text
> 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:

```text
$ ./configure --with-intl=none
```

Windows:

```text
> vcbuild intl-none
```

#### Use existing installed ICU (Unix / Macintosh only):

```text
$ 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](http://icu-project.org/download).
Download the file named something like `icu4c-**##.#**-src.tgz` (or
`.zip`).

Unix / Macintosh

```text
# 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](http://icu-project.org/download) (or `.zip`)
as `deps/icu` (You'll have: `deps/icu/source/...`)

```text
> vcbuild full-icu
```
