# Making Changes 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).

## Maintainers
|
|
|
|
You can find the list of maintainers [here](https://docs.ruby-lang.org/en/master/maintainers_rdoc.html#label-Maintainers).
|
|
|
|
## Build
|
|
|
|
First, install its dependencies using:
|
|
|
|
```
|
|
bundle install
|
|
```
|
|
|
|
### Libraries with C-extension
|
|
|
|
If the library has a `/ext` directory, it has C files that you need to compile with:
|
|
|
|
```
|
|
bundle exec rake compile
|
|
```
|
|
|
|
## Running tests
|
|
|
|
All standard libraries use [test-unit](https://github.com/test-unit/test-unit) as the test framework.
|
|
|
|
To run all tests:
|
|
|
|
```
|
|
bundle exec rake test
|
|
```
|
|
|
|
To run a single test file:
|
|
|
|
```
|
|
bundle exec rake test TEST="test/test_foo.rb"
|
|
```
|
|
|
|
To run a single test case:
|
|
|
|
```
|
|
bundle exec rake test TEST="test/test_foo.rb" TESTOPS="--name=/test_mytest/"
|
|
```
