## 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. You will need to run '`make distclean-ext`'
to remove old configuration after installing them in such a case.

= Contributing to Ruby
Ruby has a vast and friendly community with hundreds of people contributing to
a thriving open-source ecosystem. This guide is designed to cover ways for
participating in the development of CRuby.
There are plenty of ways for you to help even if you're not ready to write
code or documentation. You can help by reporting issues, testing patches, and
trying out beta releases with your applications.
== How To Report
If you've encountered a bug in Ruby please report it to the redmine issue
tracker available at {bugs.ruby-lang.org}[https://bugs.ruby-lang.org/]. Do not
report security vulnerabilities here, there is a {separate
channel}[rdoc-label:label-Reporting+Security+Issues] for them.
There are a few simple steps you should follow in order to receive feedback
on your ticket.
* If you haven't already,
{sign up for an account}[https://bugs.ruby-lang.org/account/register] on the
bug tracker.
* Try the latest version.
If you aren't already using the latest version, try installing a newer
stable release. See
{Downloading Ruby}[https://www.ruby-lang.org/en/downloads/].
* Look to see if anyone already reported your issue, try
{searching on redmine}[https://bugs.ruby-lang.org/projects/ruby-master/issues]
for your problem.
* If you can't find a ticket addressing your issue,
{create a new one}[https://bugs.ruby-lang.org/projects/ruby-master/issues/new].
* Choose the target version, usually current. Bugs will be first fixed in the
current release and then {backported}[rdoc-label:label-Backport+Requests].
* Fill in the Ruby version you're using when experiencing this issue
(<code>ruby -v</code>).
* Attach any logs or reproducible programs to provide additional information.
Reproducible scripts should be as small as possible.
* Briefly describe your problem. A 2-3 sentence description will help give a
quick response.
* Pick a category, such as core for common problems, or lib for a standard
library.
* Check the {Maintainers
list}[https://bugs.ruby-lang.org/projects/ruby/wiki/Maintainers] and assign
the ticket if there is an active maintainer for the library or feature.
* If the ticket doesn't have any replies after 10 days, you can send a
reminder.
* Please reply to feedback requests. If a bug report doesn't get any feedback,
it'll eventually get rejected.
=== Reporting to downstream distributions
You can report downstream issues for the following distributions via their bug tracker:
* {debian}[https://bugs.debian.org/cgi-bin/pkgreport.cgi?src=ruby-defaults]
* {freebsd}[http://www.freebsd.org/cgi/query-pr-summary.cgi?text=ruby]
* {redhat}[https://bugzilla.redhat.com/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&bug_status=MODIFIED]
* {macports}[https://trac.macports.org/query?status=assigned&status=new&status=reopened&port=~ruby]
* etc (add your distribution bug tracker here)
== Reporting Security Issues
Security vulnerabilities receive special treatment since they may negatively
affect many users. There is a private mailing list that all security issues
should be reported to and will be handled discretely. Email the
mailto:security@ruby-lang.org list and the problem will be published after
fixes have been released. You can also encrypt the issue using {the PGP public
key}[https://www.ruby-lang.org/security.asc] for the list.
== Reporting Other Issues
If you're having an issue with the website, or maybe the mailing list, you can
contact the webmaster to help resolve the problem.
The current webmaster is:
* Hiroshi SHIBATA (hsbt)
You can also report issues with the ruby-lang.org website on the issue tracker:
* {issue tracker}[https://github.com/ruby/www.ruby-lang.org/issues]
== Resolve Existing Issues
As a next step beyond reporting issues you can help the core team resolve
existing issues. If you check the Everyone's Issues list in GitHub Issues,
you will find a lot of issues already requiring attention. What can you do for
these? Quite a bit, actually:
When a bug report goes for a while without any feedback, it goes to the bug
graveyard which is unfortunate. If you check the {issues
list}[https://bugs.ruby-lang.org/projects/ruby-master/issues] you will find lots
of delinquent bugs that require attention.
You can help by verifying the existing tickets, try to reproduce the reported
issue on your own and comment if you still experience the bug. Some issues
lack attention because of too much ambiguity, to help you can narrow down the
problem and provide more specific details or instructions to reproduce the
bug. You might also try contributing a failing test in the form of a patch,
which we will cover later in this guide.
It may also help to try out patches other contributors have submitted to
redmine, if gone without notice. In this case the +patch+ command is your
friend, see <code>man patch</code> for more information. Basically this would
go something like this:
cd path/to/ruby
patch -p0 < path/to/patch
You will then be prompted to apply the patch with the associated files. After
building ruby again, you should try to run the tests and verify if the change
actually worked or fixed the bug. It's important to provide valuable feedback
on the patch that can help reach the overall goal, try to answer some of these
questions:
* What do you like about this change?
* What would you do differently?
* Are there any other edge cases not tested?
* Is there any documentation that would be affected by this change?
If you can answer some or all of these questions, you're on the right track.
If your comment simply says "+1", then odds are that other reviewers aren't
going to take it too seriously. Show that you took the time to review the
patch.
== How To Request Features
If there's a new feature that you want to see added to Ruby, you will need to
write a convincing proposal and patch to implement the feature.
For new features in CRuby, use the {'Feature'
tracker}[https://bugs.ruby-lang.org/projects/ruby-master/issues?set_filter=1&tracker_id=2]
on ruby-master. For non-CRuby dependent features, features that would apply to
alternate Ruby implementations such as JRuby and Rubinius, use the {CommonRuby
tracker}[https://bugs.ruby-lang.org/projects/common-ruby].
When writing a proposal be sure to check for previous discussions on the
topic and have a solid use case. You will need to be persuasive and convince
Matz on your new feature. You should also consider the potential compatibility
issues that this new feature might raise.
Consider making your feature into a gem, and if there are enough people who
benefit from your feature it could help persuade ruby-core. Although feature
requests can seem like an alluring way to contribute to Ruby, often these
discussions can lead nowhere and exhaust time and energy that could be better
spent fixing bugs. Choose your battles.
A good template for a feature proposal should look something like this:
[Abstract]
Summary of your feature
[Background]
Describe current behavior and why it is problem. Related work, such as
solutions in other language helps us to understand the problem.
[Proposal]
Describe your proposal in details
[Details]
If it has complicated feature, describe it
[Usecase]
How would your feature be used? Who will benefit from it?
[Discussion]
Discuss about this proposal. A list of pros and cons will help start
discussion.
[Limitation]
Limitation of your proposal
[Another alternative proposal]
If there are alternative proposals, show them.

== Backport Requests
When a new version of Ruby is released, it starts at patch level 0 (p0), and
bugs will be fixed first on the master branch. If it's determined that a bug
exists in a previous version of Ruby that is still in the bug fix stage of
maintenance, then a patch will be backported. After the maintenance stage of a
particular Ruby version ends, it goes into "security fix only" mode which
means only security related vulnerabilities will be backported. Versions in
End-of-life (EOL) will not receive any updates and it is recommended you
upgrade as soon as possible.
If a major security issue is found or after a certain amount of time since the
last patch level release, a new patch-level release will be made.
When submitting a backport request please confirm the bug has been fixed in
newer versions and exists in maintenance mode versions. There is a backport
tracker for each major version still in maintenance where you can request a
particular revision merged in the affected version of Ruby.
Each major version of Ruby has a release manager that should be assigned to
handle backport requests. You can find the list of release managers on the
{wiki}[https://bugs.ruby-lang.org/projects/ruby/wiki/ReleaseEngineering].
=== Branches
Status and maintainers of branches are listed on the
{wiki}[https://bugs.ruby-lang.org/projects/ruby/wiki/ReleaseEngineering].
== Running tests
In order to help resolve existing issues and contributing patches to Ruby you
need to be able to run the test suite.
CRuby uses git for source control, the {git homepage}[https://git-scm.com/]
has installation instructions with links to documentation for learning more
about git. There is a mirror of the repository on {github}[https://github.com/ruby/ruby].
For other resources see the {ruby-core documentation on
ruby-lang.org}[https://www.ruby-lang.org/en/community/ruby-core/].
Install the prerequisite dependencies for building the CRuby interpreter to
run tests.
* C compiler
* autoconf - 2.67 or later, preferably 2.69.
* bison - 2.0 or later, preferably 3.4.
* gperf - 3.0.3 or later, preferably 3.1.
* ruby - Ruby itself is prerequisite in order to build Ruby from source.
You should use [a maintained version of Ruby](https://www.ruby-lang.org/en/downloads/).
You should also have access to development headers for the following
libraries, but these are not required:
* NDBM/QDBM
* GDBM
* OpenSSL/LibreSSL
* readline/editline(libedit)
* zlib
* libffi
* libyaml
* libexecinfo (FreeBSD)
Now let's build CRuby:
* Checkout the CRuby source code:
git clone https://github.com/ruby/ruby.git ruby-master
* Generate the configuration files and build:
cd ruby-master
./autogen.sh
mkdir build && cd build # its good practice to build outside of source dir
mkdir ~/.rubies # we will install to .rubies/ruby-master in our home dir
../configure --prefix="${HOME}/.rubies/ruby-master"
make up && make install
After adding Ruby to your PATH, you should be ready to run the test suite:
make test
You can also use +test-all+ to run all of the tests with the RUNRUBY
interpreter just built. Use TESTS or RUNRUBYOPT to pass parameters, such as:
make test-all TESTS=-v
This is also how you can run a specific test from our build dir:
make test-all TESTS=drb/test_drb.rb
You can run +test+ and +test-all+ at once by +check+ .
make check
For older versions of Ruby you will need to run the build setup again after
checking out the associated branch in git, for example if you wanted to
checkout 1.9.3:
git clone https://github.com/ruby/ruby.git --branch ruby_1_9_3
Once you checked out the source code, you can update the local copy by:
make up
Or, update, build, install and check, by just:
make love
== Contributing Documentation
If you're interested in contributing documentation directly to CRuby there is
some information available at
{Contributing}[https://github.com/ruby/ruby#contributing].
There is also the {Ruby Reference
Manual}[https://github.com/rurema/doctree/wiki] in Japanese.
== Contributing A Patch
=== Deciding what to patch
Before you submit a patch, there are a few things you should know:
* Pay attention to the maintenance policy for stable and maintained versions of Ruby.
* Released versions in security mode will not merge feature changes.
* Search for previous discussions on ruby-core to verify the maintenance policy
* Patches must be distributed under Ruby's license.
* This license may change in the future, you must join the discussion if you don't agree to the change
To improve the chance your patch will be accepted please follow these simple rules:
* Bug fixes should be committed on master first
* Format of the patch file must be a unified diff (ie: diff -pu, svn diff, or git diff)
* Don't introduce cosmetic changes
* Follow the original coding style of the code
* Don't mix different changes in one commit
First thing you should do is check out the code if you haven't already:
git clone https://github.com/ruby/ruby.git ruby-master
Now create a dedicated branch:
cd ruby-master
git checkout -b my_new_branch
The name of your branch doesn't really matter because it will only exist on
your local computer and won't be part of the official Ruby repository. It will
be used to create patches based on the differences between your branch and
master, or edge Ruby.
=== Coding style
Here are some general rules to follow when writing Ruby and C code for CRuby:
* Indent 4 spaces for C without tabs (old codes might use tabs for eight-space indentation,
but newer codes recommend to use spaces only)
* Indent 2 space tabs for Ruby
* Do not use TABs in ruby codes
* ANSI C style for 1.9+ for function declarations
* Follow C90 (not C99) Standard
* PascalStyle for class/module names.
* UNDERSCORE_SEPARATED_UPPER_CASE for other constants.
* Capitalize words.
* ABBRs should be all upper case.
* Do as others do
=== Commit messages
When you're ready to commit:
git commit path/to/files
This will open your editor in which you write your commit message.
Use the following style for commit messages:
* Use a succinct subject line.
* Include reasoning behind the change in the commit message, focusing on why
the change is being made.
* Refer to redmine issue (such as Fixes [Bug #1234] or Implements
[Feature #3456]), or discussion on the mailing list
(such as [ruby-core:12345]).
* For GitHub issues, use [GH-#] (such as [Fixes GH-234]).
* Follow the style used by other committers.
=== Contributing your code
Now that you've got some code you want to contribute, let's get set up to
generate a patch. Start by forking the github mirror, check the {github docs on
forking}[https://help.github.com/articles/fork-a-repo] if you get stuck here.
You will only need a github account if you intend to host your repository
on github.
Next copy the writable url for your fork and add it as a git remote, replace
"my_username" with your github account name:
git remote add my_fork git@github.com:my_username/ruby.git
# Now we can push our branch to our fork
git push my_fork my_new_branch
In order to generate a patch that you can upload to the bug tracker, we can use
the github interface to review our changes just visit
https://github.com/my_username/ruby/compare/master...my_new_branch
Next, you can simply add '.patch' to the end of this URL and it will generate
the patch for you, save the file to your computer and upload it to the bug
tracker. Alternatively you can submit a pull request, but for the best chances
to receive feedback add it is recommended you add it to redmine.
Since git is a distributed system, you are welcome to host your git repository
on any {publicly accessible hosting
site}[https://git.wiki.kernel.org/index.php/GitHosting], including {hosting your
own}[https://www.kernel.org/pub/software/scm/git/docs/user-manual.html#public-repositories]
You may use the {'git format-patch'}[https://git-scm.com/docs/git-format-patch]
command to generate patch files to upload to redmine. You may also use
the {'git request-pull'}[https://git-scm.com/docs/git-request-pull] command for
formatting pull request messages to redmine.
=== Updating the official repository
If you are a committer, you can push changes directly into the official
repository:
git push origin your-branch-name:master
However, it is likely will have become outdated, and you will have to
update it. In that case, run:
git fetch origin
git rebase remotes/origin/master
and then try pushing your changes again.

# Building Ruby
## Quick start guide
1. Install the prerequisite dependencies for building the CRuby interpreter:
* C compiler
* autoconf - 2.67 or later
* bison - 2.0 or later
* gperf - 3.0.3 or later
* ruby - 2.7 or later
2. Install optional, recommended dependencies:
* OpenSSL/LibreSSL
* readline/editline (libedit)
* zlib
* libffi
* libyaml
* libexecinfo (FreeBSD)
3. Checkout the CRuby source code:
```
git clone https://github.com/ruby/ruby.git
```
4. Generate the configuration files and build:
```
./autogen.sh
mkdir build && cd build # its good practice to build outside of source dir
mkdir ~/.rubies # we will install to .rubies/ruby-master in our home dir
../configure --prefix="${HOME}/.rubies/ruby-master"
make install
```
5. [Run tests](testing_ruby.md) to confirm your build succeeded
## More details
If you're interested in continuing development on Ruby, here are more details
about Ruby's build to help out.
### Running make scripts in parallel
To run make scripts in parallel, pass flag `-j<number of processes>`. For instance,
to run tests on 8 processes, use:
```
make test-all -j8
```
### Miniruby vs Ruby
Miniruby is a version of Ruby which has no external dependencies and lacks certain features.
It can be useful in Ruby development because it allows for faster build times. Miniruby is
built before Ruby. A functional Miniruby is required to build Ruby. To build Miniruby:
```
make miniruby
```
## Debugging
You can use either lldb or gdb for debugging. Before debugging, you need to create a `test.rb`
with the Ruby script you'd like to run. You can use the following make targets:
* `make run`: Runs `test.rb` using Miniruby
* `make lldb`: Runs `test.rb` using Miniruby in lldb
* `make gdb`: Runs `test.rb` using Miniruby in gdb
* `make runruby`: Runs `test.rb` using Ruby
* `make lldb-runruby`: Runs `test.rb` using Ruby in lldb
* `make gdb-runruby`: Runs `test.rb` using Ruby in gdb

= Documentation Guide
# Documentation Guide
This guide discusses recommendations for documenting
classes, modules, and methods
in the Ruby core and in the Ruby standard library.
== Goal
## Generating documentation
Most Ruby documentation lives in the source files and is written in [RDoc format](https://ruby.github.io/rdoc/RDoc/Markup.html).
Some pages live under the `doc` folder and can be written in either `.rdoc` or `.md` format, determined by the file extension.
To generate the output of documentation changes in HTML in the `{build folder}/.ext/html` directory, run the following inside your build directory:
```
make html
```
Then you can preview your changes by opening `{build folder}/.ext/html/index.html` file in your browser.
## Goal
The goal of Ruby documentation is to impart the most important
and relevant in the shortest time.

information or unnecessary examples is not good either.
Use your judgment about what the user needs to know.
== General Guidelines
## General Guidelines
- Keep in mind that the reader may not be fluent in \English.
- Write short declarative or imperative sentences.
- Group sentences into (ideally short) paragraphs,
each covering a single topic.
- Organize material with {headers}[rdoc-ref:RDoc::Markup@Headers].
- Organize material with [headers](rdoc-ref:RDoc::Markup@Headers).
- Refer to authoritative and relevant sources using

- Use simple verb tenses: simple present, simple past, simple future.
- Use simple sentence structure, not compound or complex structure.
- Avoid:
- Excessive comma-separated phrases;
consider a [list](rdoc-ref:RDoc::Markup@Simple+Lists).
- Idioms and culture-specific references.
- Overuse of headers.
- Using US-ASCII-incompatible characters in C source files;

In general, \RDoc's auto-linking should not be suppressed.
For example, we should write +Array+, not <tt>\Array</tt>.
For example, we should write `Array`, not <tt>\Array</tt>.
We might consider whether to suppress when:
- The word in question does not refer to a Ruby entity
(e.g., some uses of _Class_ or _English_).
- The reference is to the current class document
(e.g., _Array_ in the documentation for class +Array+).

=== Calling Sequence (for methods written in C)
### Calling Sequence (for methods written in C)
For methods written in Ruby, \RDoc documents the calling sequence automatically.

```
* call-seq:
* array.count -> integer
* array.count(obj) -> integer
* array.count {|element| ... } -> integer
```
When creating the <tt>call-seq</tt>, use the form

# Contributing a pull request
## Code style
Here are some general rules to follow when writing Ruby and C code for CRuby:
* Do not change code unrelated to your pull request (including style fixes)
* Indent 4 spaces for C without tabs (tabs are two levels of indentation, equivalent to 8 spaces)
* Indent 2 spaces for Ruby without tabs
* ANSI C style for function declarations
* Follow C99 Standard
* PascalStyle for class/module names
* UNDERSCORE_SEPARATED_UPPER_CASE for other constants
* Abbreviations should be all upper case
## Commit messages
Use the following style for commit messages:
* Use a succinct subject line
* Include reasoning behind the change in the commit message, focusing on why the change is being made
* Refer to issue (such as `Fixes [Bug #1234]` or `Implements [Feature #3456]`), or discussion on the mailing list (such as [ruby-core:12345])
## CI
GitHub actions will run on each pull request.
There is [a CI that runs on master](https://rubyci.org/). It has broad coverage of different systems and architectures, such as Solaris SPARC and macOS.
# Contributing to standard libraries
Everything in the [lib](https://github.com/ruby/ruby/tree/master/lib) directory is mirrored from a standalone repository into the Ruby repository.
If you'd like to make contributions to standard libraries, do so in the standalone repositories, and the
changes will be automatically mirrored into the Ruby repository.
For example, CSV lives in [a separate repository](https://github.com/ruby/csv) and is mirrored into [Ruby](https://github.com/ruby/ruby/tree/master/lib/csv).

### Reporting website issues
If you're having an issue with the bug tracker or the mailing list, you can
contact the webmaster, Hiroshi SHIBATA (hsbt@ruby-lang.org).
You can report issues with ruby-lang.org on the
[repo's issue tracker](https://github.com/ruby/www.ruby-lang.org/issues).
## Requesting features
If there's a new feature that you want to see added to Ruby, you will need to
write a proposal on [the Redmine issue tracker](https://bugs.ruby-lang.org/projects/ruby-master/issues/new).
When you open the issue, select `Feature` in the Tracker dropdown.
When writing a proposal, be sure to check for previous discussions on the
topic and have a solid use case. You should also consider the potential
compatibility issues that this new feature might raise. Consider making
your feature into a gem, and if there are enough people who benefit from
your feature it could help persuade Ruby core.
Here is a template you can use for a feature proposal:
```
[Abstract]
Briefly summarize your feature
[Background]
Describe current behavior
[Proposal]
Describe your feature in detail
[Use cases]
Give specific example uses of your feature
[Discussion]
Describe why this feature is necessary and better than using existing features
[See also]
Link to other related resources (such as implementations in other languages)
```
## Backport requests
If a bug exists in a released version of Ruby, please report this in the issue.
Once this bug is fixed, the fix can be backported if deemed necessary. Only Ruby
committers can request backporting, and backporting is done by the backport manager.
New patch versions are released at the discretion of the backport manager.
[Ruby versions](https://www.ruby-lang.org/en/downloads/) can be in one of three maintenance states:
* Stable releases: backport any bug fixes
* Security maintenance: only backport security fixes
* End of life: no backports, please upgrade your Ruby version
## Add context to existing issues
There are several ways you can help with a bug that aren't directly
resolving it. These include:
* Verifying or reproducing the existing issue and reporting it
* Adding more specific reproduction instructions
* Contributing a failing test as a patch (see ["making changes to Ruby"](making_changes_to_ruby.md))
* Testing patches that others have submitted (see ["making changes to Ruby"](making_changes_to_ruby.md))

# Testing Ruby
## Test suites
There are several test suites in the Ruby codebase:
We can run any of the make scripts [in parallel](building_ruby.md#label-Running+make+scripts+in+parallel) to speed them up.
1. [bootstraptest/](https://github.com/ruby/ruby/tree/master/bootstraptest)
This is a small test suite that runs on Miniruby (see [building Ruby](building_ruby.md#label-Miniruby+vs+Ruby)). We can run it with:
```
make btest
```
To run it with logs, we can use:
```
make btest OPTS=-v
```
If we want to run the bootstrap test suite on Ruby (not Miniruby), we can use:
```
make test
```
To run it with logs, we can use:
```
make test OPTS=-v
```
2. [test/](https://github.com/ruby/ruby/tree/master/test)
This is a more comprehensive test suite that runs on Ruby. We can run it with:
```
make test-all
```
We can run a specific test file in this suite using the `TESTS` environment variable, for example:
```
make test-all TESTS=test/ruby/test_array.rb
```
We can run a specific test in this suite using the `TESTS` environment variable, specifying
first the file name, and then the test name, prefixed with `--name`. For example:
```
make test-all TESTS="../test/ruby/test_alias.rb --name=/test_aias_with_zsuper_method/"
```
To run these specs with logs, we can use:
```
make test-all TESTS=-v
```
If we would like to run both the `test/` and `bootstraptest/` test suites, we can run
```
make check
```
3. [spec/ruby](https://github.com/ruby/ruby/tree/master/spec/ruby)
This is a test suite that exists in [the Ruby spec repository](https://github.com/ruby/spec) and is mirrored into the `spec/ruby` directory in the Ruby repository. It tests the behavior of the Ruby programming language. We can run this using:
```
make test-spec
```
To run a specific file, we can use `MSPECOPT` to specify the file:
```
make test-spec MSPECOPT=spec/ruby/core/array/any_spec.rb
```
To run a specific test, we can use the `--example` flag to match against the test name:
```
make test-spec MSPECOPT="../spec/ruby/core/array/any_spec.rb --example='is false if the array is empty'"
```
To run these specs with logs, we can use:
```
make test-spec MSPECOPT=-Vfs
```
4. [spec/bundler](https://github.com/ruby/ruby/tree/master/spec/bundler)
The bundler test suite exists in [the RubyGems repository](https://github.com/rubygems/rubygems/tree/master/bundler/spec) and is mirrored into the `spec/bundler` directory in the Ruby repository. We can run this using:
```
make test-bundler

# Ruby Hacking Guide
This document gives some helpful instructions which should make your
experience as a Ruby core developer easier.
## Setup
### Make
It's common to want to compile things as quickly as possible. Ensuring
`make` has the right `--jobs` flag will ensure all processors are
utilized when building software projects To do this effectively, you
can set `MAKEFLAGS` in your shell configuration/profile:
``` shell
# On macOS with Fish shell:
export MAKEFLAGS="--jobs "(sysctl -n hw.ncpu)
# On macOS with Bash/ZSH shell:
export MAKEFLAGS="--jobs $(sysctl -n hw.ncpu)"
# On Linux with Fish shell:
export MAKEFLAGS="--jobs "(nproc)
# On Linux with Bash/ZSH shell:
export MAKEFLAGS="--jobs $(nproc)"
```
## Configure Ruby
It's generally advisable to use a build directory.
``` shell
./autogen.sh
mkdir build
cd build
../configure --prefix $HOME/.rubies/ruby-head
make install
```
### Without Documentation
If you are frequently building Ruby, this will reduce the time it
takes to `make install`.
``` shell
../configure --disable-install-doc
```
## Running Ruby
### Run Local Test Script
You can create a file in the Ruby source root called `test.rb`. You
can build `miniruby` and execute this script:
``` shell
make run
```
If you want more of the standard library, you can use `runruby`
instead of `run`.
## Running Tests
You can run the following tests at once:
``` shell
make check
```
### Run Bootstrap Tests
There are a set of tests in `bootstraptest/` which cover most basic
features of the core Ruby language.
``` shell
make test
```
### Run Extensive Tests
There are extensive tests in `test/` which cover a wide range of
features of the Ruby core language.
``` shell
make test-all
```
You can run specific tests by specifying their path:
``` shell
make test-all TESTS=../test/fiber/test_io.rb
```
### Run Ruby Spec Suite Tests
The [Ruby Spec Suite](https://github.com/ruby/spec/) is a test suite
that aims to provide an executable description for the behavior of the
language.
``` shell
make test-spec
```

# How to use "configure" and "make" commands for Ruby
This is for developers of Ruby.
If you are a user of Ruby, please see README.md.
## In-place build
```
$ ./autogen.sh
$ ./configure --prefix=$PWD/local
$ make
$ make install
$ ./local/bin/ruby -e 'puts "Hello"'
Hello
```
## Out-of-place build
```
$ ./autogen.sh
$ mkdir ../ruby-build
$ cd ../ruby-build
$ ../ruby-src/configure --prefix=$PWD/local
$ make
$ make install
$ ./local/bin/ruby -e 'puts "Hello"'
Hello
```
## How to run the whole test suite
```
$ make check
```
It runs (about) four test suites:
* `make test` (a test suite for the interpreter core)
* `make test-all` (for all builtin classes and libraries)
* `make test-spec` (a conformance test suite for Ruby implementations)
* `make test-bundler` (a test suite for the bundler examples)
## How to run the test suite with log
```
$ make test OPTS=-v
$ make test-all TESTS=-v
$ make test-spec MSPECOPT=-Vfs
```
## How to run a part of the test suite
### Runs a directory
```
$ make test-all TESTS=test/rubygems
$ make test-all TESTS=rubygems
```
### Runs a file
```
$ make test-all TESTS=test/ruby/test_foo.rb
$ make test-all TESTS=ruby/foo
```
### Runs a test whose name includes test_bar
```
$ make test-all TESTS="test/ruby/test_foo.rb -n /test_bar/"
```
### Runs a file or directory with GNU make
```
$ make test/ruby/test_foo.rb
$ make test/ruby/test_foo.rb TESTOPTS="-n /test_bar/"
```
### Runs a ruby-spec directory
```
$ make test-spec MSPECOPT=spec/ruby/core/foo
```
### Runs a ruby-spec file
```
$ make test-spec MSPECOPT=spec/ruby/core/foo/bar_spec.rb
```
### Runs a ruby-spec file or directory with GNU make
```
$ make spec/ruby/core/foo/bar_spec.rb
```
### Runs a bundler spec file
```
$ make test-bundler BUNDLER_SPECS=commands/exec_spec.rb:58
```
## How to measure coverage of C and Ruby code
You need to be able to use gcc (gcov) and lcov visualizer.
```
$ ./autogen.sh
$ ./configure --enable-gcov
$ make
$ make update-coverage
$ rm -f test-coverage.dat
$ make test-all COVERAGE=true
$ make lcov
$ open lcov-out/index.html
```
If you need only C code coverage, you can remove `COVERAGE=true` from the above process.
You can also use `gcov` command directly to get per-file coverage.
If you need only Ruby code coverage, you can remove `--enable-gcov`.
Note that `test-coverage.dat` accumulates all runs of `make test-all`.
Make sure that you remove the file if you want to measure one test run.
You can see the coverage result of CI: https://rubyci.org/coverage
## How to benchmark
