Ruby and Rails Snippets for Visual Studio Code
Very similar to Vense's rails extension and Peng Lv's snippets but with my own twists and added snippets :)
I plan to modify, extend and add more to this over time as I learn more about Ruby and Rails.
Supported file extensions
- Ruby (.rb)
- Embedded Ruby (html.erb)
- Slim (html.slim)
tips
control/command + space loads the snippet suggestions if they aren't shown right away.$1 is where the snippet starts. $0 is where the snippet ends.- Press
