RubyScope

Ruby colored binoculars for your code.

Installation

RubyScope is available as a normal gem:

gem install ruby_scope

Alternatively, you can get the source from GitHub:

git clone git://github.com/adamsanderson/ruby_scope.git

If you pull the source, install with rake install. See below for more information on hacking around in the source.

Using RubyScope

You can invoke ruby_scope from the command line:

Usage: ruby_scope [options] path

Queries:
        --def NAME                   Find the definition of instance method NAME
        --class-def NAME             Find the definition of class method NAME
        --call NAME                  Find method calls of NAME
        --class NAME                 Find definition of NAME
        --variable NAME              Find references to variable NAME
        --assign NAME                Find assignments to NAME
        --any NAME                   Find any reference to NAME (class, variable, number)
        --custom SEXP_PATH           Searches for a custom SexpPath

Options:
    -R                               Recursively search folders
        --no-cache                   Do not use a cache
        --cache PATH                 Use the cache at PATH (defaults to current dir)
    -v, --verbose                    Verbose output
    -h, --help                       Show this message

Find all the places run or save are called in your secret project:

ruby_scope -R --def 'run' --def 'save' ~/SecretProject

Where do I assign values to a:

ruby_scope -R --assign 'a' ~/SecretProject

Of course regular expressions are fair game:

ruby_scope -R --def '/^test/' ~/SecretProject

Wicked hacker? Go crazy and write your own SexpPath queries:

ruby_scope --custom 's(:call, s(:ivar, atom), :save, _)'

That finds all the saves on instance variables by the way.

Hacking RubyScope

Want to extend ruby_scope? Take a look at cli.rb, at the moment this is where all of the queries are actually generated. Have an idea for a better caching mechanism? Look at sexp_cache.rb.

The source is on GitHub, so fork off:
