# 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`.
|
|
|
|
### 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 RubySpec Tests
|
|
|
|
RubySpec is a project to write a complete, executable specification for the Ruby programming language.
|
|
|
|
``` shell
|
|
make test-all test-rubyspec
|
|
```
|
