If you use VIM, you’re probably familiar with the incredible % command. It allows you to jump back and forth between opening and closing block operators, for example {} [] ().
Unfortunately, the default doesn’t support HTML, and subsequently RHTML tags.
Thank god for matchit!
From ~/, create a .vim directory (if it doesn't already exist), and extract matchit.zip.Matchit should be up and running for a number of additional languages (ADA, HTML, etc). Now we just need to associate RHTML files with the proper type (HTML).
Then in ~/.vim, create a file called filetype.vim with the following content:augroup filetypedetect
au! BufRead,BufNewFile *.rhtml setfiletype xhtml
augroup END
You can now place your cursor at the beginning of a <% ... %> block and hit %. Tada! (This also provides the added benefit of HTML snytax highlighting)
UPDATE: The VIM-Ruby project includes matchit definitions for .rb files which allow you to jump between def/end declarations as well!
I use VIM, but I’m more familiar with the infamous; (. )( .) command. It should come as a default upgrade with the ubuntu software package. Check your c:/boobs directory. It allows all the HTML you can throw at it.
