Is there a ruby equivalent of ColdFusions cfdump tag.
which can dump any object as a html formatted output.
I want to use this to be able to dump any object into an email html body.
I know there is Pretty Print and other gems out there that output colour coded well formatted strings to the console, but I want to be able to generate a html string, dumping out the entire data type I need.
There's a CodeRay colorizer.
CodeRay.scan("5.times do\n puts 'Hello, world!'\nend", :ruby).
div(:line_numbers => :table)
I use it to highlight JSON snippets in my wiki, so if you pretty print objects to JSON and then pass it through coderay, it'll certainly work.
The rails-cfdump project is abandoned, but it looks like its output is very similar to CF's <cfdump>/WriteDump().
The dom gem that I have developed lets you write HTML string from Ruby code. Using it, you can do things like:
require "dom"
["foo".dom(:span, class: "bold"), "bar"].dom(:div).dom(:body).dom(:html)
# => "<html><body><div><span class=\"bold\">foo</span>bar</div></body></html>"
