Repository files navigation

Starscope is a code indexer, search and navigation tool forRuby,Golang, andJavaScript with a design intendedto make it easy to addsupport for other languages.

Inspired by the extremely popularCtagsandCscope utilities, Starscope can answer alot of questions about your code. It can tell you:

• where methods are defined
• where methods are called
• where variables are assigned
• where symbols are used
• where files and libraries are imported or required

While Ctags already supports many languages, it can only tell you where thingsare defined. Cscope can answer a lot more of your questions, but it is limitedto just the C language family. Starscope was written to combine the power ofCscope with the flexibility of Ctags, bringing full code indexing to as manydevelopers as possible.

Install it as a gem:

$ gem install starscope

Build your database by just running it in the project directory:

$ cd ~/my-project$ starscope

Ask it things directly:

$ starscope -q calls,new # Lists all callers of new

Export it to various existing formats for automatic integration with your editor:

$ starscope -e ctags$ starscope -e cscope
