Ruby text objects Fri, 18 Jul 2014
Yesterday I discovered a text object within Vim that I’d not realised existed, which served as a perfect tip post up onto this blog (and to try and get back to doing it more regularly!).
Any seasoned Ruby + Vim user has probably got Drew Neil’s textobj-rubyblock plugin installed, which adds the text objects
ir to select around and inside a ruby block.
However, what I didn’t know about was the text object
im, which is provided by vim-ruby (which comes with Vim by default), to select the contents within the current Ruby method, and its sibling
am, to select around the method. Hat tip to @tomstuart for that one:
It took me a few minutes to work out how to select the body of a Ruby method in Vim, but I was happy when the answer turned out to be “vim”.— Tom Stuart (@tomstuart) July 17, 2014
Drew Neil (@nelstrom)) then followed up explaining that it was recently added to vim-ruby:
@telemachus it’s a text object defined in the vim-ruby plugin: https://t.co/YZSmUPWr0P Should be available out the box in recent Vim builds.— Drew Neil (@nelstrom) July 17, 2014
If you’re running a recent version of Vim you should have this functionality, but if you’re not, you can always install the latest version of vim-ruby as a plugin through Vundle / Pathogen. The best solution though if possible is to simply upgrade your Vim.
Whilst reading to produce this blog post I also discovered the objects
aM, which select in and around the current Ruby class, too. All of these are going to be really useful in my day to day development.
