Trying to set up Guardfile for web development, cannot add sub-directory check

I am trying to set-up a guardfile for a simple web development project.

I want it to check the HTML files in the current dir, and the CSS files in the ./css/ directory.

I am really new to regular expressions. I have managed to match the HTML files in the current directory with this regexpr ^.+\.html$.
I need to descend to the directory tree to access ./css/anyfile.css files.

I've tried this: ^(.+\.html)|(css/.+\.css)$. I am checking the regular expression with ls | egrep 'regexpr', running it at project root. I only get as result the .html file.

It seems weird that it doesn't work, because here using this block: 

guard 'livereload' do
  watch(%r{app/views/.+\.(erb|haml|slim)})
  watch(%r{app/helpers/.+\.rb})
  watch(%r{public/.+\.(css|js|html)})
  watch(%r{config/locales/.+\.yml})
  # Rails Assets Pipeline
  watch(%r{(app|vendor)(/assets/\w+/(.+\.(css|js|html))).*}) { |m| "/assets/#{m[3]}" }
end

it can acess subdirectories such as app,public and config.

Solution

  • You need to escape the forward slash, so your regexp becomes ^(.+\.html)|(css\/.+\.css)$. You can use http://rubular.com to check if the RegExp is a valid Ruby Regexp.
