How Do You Pass a Method to gsub in Ruby?

I am building off of Ben's static site generator, and I wanted to DRY it up a bit.

One thing led to another and I built my own static site generator today

#webdev #javascript #ruby #html

I have a few methods:

prod_build = ARGV[0] = "production_build" # Read files def page_partials(new_page_partial) pages = "site/#{page_partial}.html" new_page_partial = File.open(pages).read end def script_partials(new_script_partial) scripts = "site/#{script_partial}.js" new_script_partial = File.open(scripts).read end def style_partial(new_style_partial) styles = "site/#{style_partial}.css" new_style_partial(styles).read end puts page_partials() 

I'm not a Rubyist, though I've dabbled in it. I assume these methods are correct, considering:

build_string = base_html # How do you use a block in a .gsub method??? .gsub("{{ head }}" {page_partials}) .gsub("{{ seo }}", seo_html) .gsub("{{ main }}", main_css) .gsub("{{ dev }}", dev_html) 

I have a bunch of .gsub methods that expect a file, will change the file name, and in the build string, will create the file.

What I want to know is, as a JavaScript dev, how to pass these methods as parameters to the .gsub method in a block and if you can do this.

Shifting paradigms

I haven't looked at this code in a month as I was sick for that long. I have no idea what I was aiming for as such I am a little lost. JavaScript handles things much differently and I am trying to apply my js knowledge to Ruby and that seems to be a bad idea.

Thanks for helping, if you can.
