cybertron is a command line tool for generating, testing and publishing
[converters](https://github.com/rajasegar/awesome-ruby-ast#converters) aka
[Codemods](https://github.com/facebook/codemod) for Ruby inspired by [codemod-cli](https://github.com/rwjblue/codemod-cli) for Javascript by [Robert Jackson](https://github.com/rwjblue)
**INFO**:
You can use a tool like [codeshift](https://github.com/rajasegar/codeshift) to run your codemods/transforms against your Ruby codebase.
For writing transforms you can also make use of the [Ruby AST Explorer](https://ruby-ast-explorer.herokuapp.com/)
## Installation
```sh
$ gem install cybertron
```
## Usage
### Create a new codemod project
```
$ cybertron new
```
Example:
```
$ cybertron new my_ruby_codemod
```
This will create a project structure like this:
```
my_ruby_codemod
| transforms
| spec
| | spec_helper.rb
.rspec
Rakefile
```
### Generate a new transform
```
$ cd
$ cybertron generate transform
```
Example:
```
$ cd my_ruby_codemod
$ cybertron generate transform my_transform
```
Now the project structure will be like this:
```
my_ruby_codemod
| transforms
| | my_transform
| | | fixtures
| | | | basic_input.rb
| | | | basic_output.rb
| | | transform.rb
| spec
| | my_transform_spec.rb
| | spec_helper.rb
.rspec
Rakefile
```
### Generate a new fixture for transform
```
$ cybertron generate fixture
```
Example:
```
$ cybertron generate fixture my_transform advanced_usage
```
Now the project structure will be like this:
```
my_ruby_codemod
| transforms
| | my_transform
| | | fixtures
| | | | basic_input.rb
| | | | basic_output.rb
| | | | advanced_usage_input.rb
| | | | advanced_usage_output.rb
| | | transform.rb
| spec
| | my_transform_spec.rb
| | spec_helper.rb
.rspec
Rakefile
```
### Run tests for your codemod transforms
```
$ cybertron spec
```
This will run all the specs in the spec folder, by comparing the input and output
fixtures against themselves for each and every transform.
### Finding help or usage instructions
To display the help message and usage instructions, just invoke `cybertron`
without any arguments
```sh
$ cybertron
```
To display help about any particular command,
```sh
$ cybertron help
```
For example, to know more about the `generate` command:
```sh
$ cybertron help generate
```

## Development
After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
