# What's Ruby
|
|
|
|
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.
|
|
|
|
## Features of Ruby
|
|
|
|
* 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
|
|
well as Windows, macOS, etc.) cf.

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

## Requirements to build from repository
|
|
|
|
1. GNU or BSD make
|
|
2. C99 compiler
|
|
3. autoconf 2.67 or higher
|
|
4. automake 1.15 or higher
|
|
5. bison 2.3 or higher
|
|
6. Ruby 2.2 or higher
|
|
|
|
When building from a released version, only a C99 compiler and GNU or BSD make
|
|
is required.
|
|
|
|
## How to compile and install
|
|
|
|
1. If you want to use Microsoft Visual C++ to compile Ruby, read
|
|
[win32/README.win32](rdoc-ref:win32/README.win32) instead of this document.
|
|
|
|
2. Run `./autogen.sh` to generate configure, when you build the source checked
|
|
out from the Git repository.
|
|
|
|
3. Run `./configure`, which will generate `config.h` and `Makefile`.
|
|
|
|
Some C compiler flags may be added by default depending on your
|
|
environment. Specify `optflags=..` and `warnflags=..` as necessary to
|
|
override them.
|
|
|
|
4. Edit `include/ruby/defines.h` if you need. Usually this step will not be needed.
|
|
|
|
5. Optional: Remove comment mark(`#`) before the module names from `ext/Setup`.
|
|
|
|
This step is only necessary if you want to link modules statically.
|
|
|
|
If you don't want to compile dynamic extensions (probably on architectures
|
|
which do not allow dynamic loading), remove comment mark from the line
|
|
"`#option nodynamic`" in `ext/Setup`.
|
|
|
|
Usually this step will not be needed.
|
|
|
|
6. Run `make`.
|
|
|
|
* On Mac, set RUBY\_CODESIGN environment variable with a signing identity.
|
|
It uses the identity to sign `ruby` binary. See also codesign(1).
|
|
|
|
7. Optionally, run '`make check`' to check whether the compiled Ruby
|
|
interpreter works well. If you see the message "`check succeeded`", your
|
|
Ruby works as it should (hopefully).
|
|
|
|
8. Run '`make install`'.
|
|
|
|
This command will create the following directories and install files into
|
|
them.
|
|
|
|
* `${DESTDIR}${prefix}/bin`
|
|
* `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}`
|
|
* `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
|
|
* `${DESTDIR}${prefix}/lib`
|
|
* `${DESTDIR}${prefix}/lib/ruby`
|
|
* `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}`
|
|
* `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
|
|
* `${DESTDIR}${prefix}/lib/ruby/site_ruby`
|
|
* `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}`
|
|
* `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
|
|
* `${DESTDIR}${prefix}/lib/ruby/vendor_ruby`
|
|
* `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}`
|
|
* `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
|
|
* `${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}`
|
|
* `${DESTDIR}${prefix}/share/man/man1`
|
|
* `${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system`
|
|
|
|
|
|
If Ruby's API version is '*x.y.z*', the `${MAJOR}` is '*x*', the
|
|
`${MINOR}` is '*y*', and the `${TEENY}` is '*z*'.
|
|
|
|
**NOTE**: teeny of the API version may be different from one of Ruby's
|
|
program version
|
|
|
|
You may have to be a super user to install Ruby.
|
|
|
|
If you fail to compile Ruby, please send the detailed error report with the
|
|
error log and machine/OS type, to help others.
|
|
|
|
Some extension libraries may not get compiled because of lack of necessary
|
|
external libraries and/or headers, then you will need to run '`make distclean-ext`'
|
|
to remove old configuration after installing them in such case.
