Vim plugin for debugging Ruby applications (using ruby-debug-ide gem)
The developer of this repository has not created any items for sale yet. Need a bug fixed? Help with integration? A different license? Create a request here:
This is a new version of the plugin, which uses debugger-xml gem, and works only with Ruby >= 1.9. If you want to use ruby-debug-ide gem and/or Ruby <= 1.8.7, you should check 'v1.0' branch (http://github.com/astashov/vim-ruby-debugger/tree/v1.0)
This Vim plugin implements interactive Ruby debugger in Vim.
This version of the plugin works only with Ruby >= 1.9. It uses debugger-xml under the hood, which is just a XML/IDE extension for the debugger gem, which supports Ruby 1.9.2 and 1.9.3 out-of-the-box, but doesn't support Ruby <= 1.8.7.
Vim >= 7.0, compiled with +signs, +clientserver and +ruby. You can verify it by VIM command:
:echo has("signs") && has("clientserver") && has("ruby") && v:version > 700
It should show result '1'.
For OS X:
The vim that ships with OS X does not use ruby, nor does it support --servername, so MacVim must be used.
Make sure that both MacVim, and mvim are installed.
If they are not, you can use homebrew (http://mxcl.github.com/homebrew/):
brew install macvim
This will install MacVim, along with the mvim command line utility.
Clone the repo
git clone git://github.com/astashov/vim-ruby-debugger.git
or just download the archive from here:
You will get the 'vim-ruby-debugger' dir with the plugin.
Copy contents of the 'vim-ruby-debugger' dir to your ~/.vim/ (or to ~/.vim/bundle/vim-ruby-debugger if you use pathogen).
Generate the local tags file
Now, you can use
to get help for the ruby-debugger plugin.
If using MacVim:
Modify your ~/.vimrc to add the following line:
let g:ruby_debugger_progname = 'mvim'
Windows is not supported, sorry, Windows users.
Run Vim. If you use gvim/mvim, it will automatically start the server, but if you use vim, you need to set servername explicitly, e.g., vim --servername VIM
Go to the directory with some your Rails application.
Run Server with Debugger:
It will run debugger-xml's rdebug-vim executable, create a UNIX socket in tmp directory, and connect to debugger-xml through it.
Set a breakpoint somewhere by <Leader>b (e.g., '\b'). You should see 'xx' symbol at current line.
Open a page with the breakpoint in a browser. Vim should automatically set the current line to the breakpoint.
After this, you can use commands:
b - set breakpoint at current line v - open/close window with variables. You can expand/collapse variables by 'o' in normal mode or left-mouse double-click n - step over s - step into c - continue
You may find useful to override default shortcut commands by F5-F8 shortcuts. Add these to your .vimrc:
map :call g:RubyDebugger.step() map :call g:RubyDebugger.next() map :call g:RubyDebugger.continue()
If you want to run tests, replace in /autoload directory rubydebugger.vim to **rubydebugger.vim** from additionals/autoload directory. And then, in command mode execute
Special thanks to tpope (for rails.vim) and Marty Grenfell (for NERDTree), mostly, I learn Vim Scripting from their projects.
