# What's Ruby
.PP
Ruby is an interpreted object\-oriented programming language often
used for web development. It also offers many scripting features
to process plain text and serialized files, or manage system tasks.
It is simple, straightforward, and extensible.
.PP
## Features of Ruby
.PP
* Simple Syntax
* **Normal** Object\-oriented Features (e.g. class, method calls)
* **Advanced** Object\-oriented Features (e.g. mix\-in, singleton\-method)
* Operator Overloading
* Exception Handling
* Iterators and Closures
* Garbage Collection
* Dynamic Loading of Object Files (on some architectures)
* Highly Portable (works on many Unix\-like/POSIX compatible platforms as
.IP
well as Windows, macOS, Haiku, etc.) cf.

## How to get Ruby
.PP
For a complete list of ways to install Ruby, including using third\-party tools
like rvm, see:
.PP
https://www.ruby\-lang.org/en/downloads/
.PP
### Git
.PP
The mirror of the Ruby source tree can be checked out with the following command:
.IP
\f(CW$ git clone https://github.com/ruby/ruby.git\fR
.PP
There are some other branches under development. Try the following command
to see the list of branches:
.IP
\f(CW$ git ls-remote https://github.com/ruby/ruby.git\fR
.PP
You may also want to use https://git.ruby\-lang.org/ruby.git (actual master of Ruby source)
if you are a committer.
.PP
### Subversion
.PP
Stable branches for older Ruby versions can be checked out with the following command:
.IP
\f(CW$ svn co https://svn.ruby-lang.org/repos/ruby/branches/ruby_2_6/ ruby\fR
.PP
Try the following command to see the list of branches:
.IP
\f(CW$ svn ls https://svn.ruby-lang.org/repos/ruby/branches/\fR

## How to compile and install
.PP
1. If you want to use Microsoft Visual C++ to compile Ruby, read
.IP
[win32/README.win32](win32/README.win32) instead of this document.
.PP
2. If does not exist or is older than , run
.IP
to (re)generate configure.
.PP
3. Run , which will generate and .
.IP
Some C compiler flags may be added by default depending on your
environment. Specify and as necessary to
override them.
.PP
4. Edit if you need. Usually this step will not be needed.
.PP
5. Remove comment mark() before the module names from (or add
.IP
module names if not present), if you want to link modules statically.
.IP
If you don't want to compile non static extension modules (probably on
architectures which do not allow dynamic loading), remove comment mark
from the line "" in .
.IP
Usually this step will not be needed.
.PP
6. Run .
.IP
* On Mac, set RUBY\e_CODESIGN environment variable with a signing identity.
.TP
It uses the identity to sign
binary. See also codesign(1).
.PP
7. Optionally, run '' to check whether the compiled Ruby
.IP
interpreter works well. If you see the message "", your
Ruby works as it should (hopefully).
.PP
8. Optionally, run and .
.TP
If you want to install bundled gems, run
and
.IP
before running .
.PP
9. Run ''.
.IP

them.

.TP
If Ruby's API version is '*x.y.z*', the
is '*x*', the
.TP
is '*y*', and the
is '*z*'.
.IP
**NOTE**: teeny of the API version may be different from one of Ruby's
program version
.IP
You may have to be a super user to install Ruby.
.PP
If you fail to compile Ruby, please send the detailed error report with the
error log and machine/OS type, to help others.
.PP
Some extension libraries may not get compiled because of lack of necessary
external libraries and/or headers, then you will need to run ''
to remove old configuration after installing them in such case.
