[BUG] - No ERB support about ruby_jard HOT 4 CLOSED

Hi @scottbarrow, thanks for your reporting. I have just tested in my local environment (Ruby 2.6.5, and 2.7.1 on Rails 6.0). It works quite well.

Could you give me some more information, such as your Ruby version, your Rails version, the environment you are running on (mac, linux?). If it's possible, could you try with a simple view, or empty view?

Ahhhhh. I can now re-produce the bug now. So, if you put something like <%= jard %>, Jard won't stop at the file, while it works well with <% jard %>. It's an interesting bug, happens with byebug as well. I'll go dive deep to see what happens.

In the mean time, you could use <% jard %> instead.

A debug story: as mentioned above, jard doesn't work with <%= jard %>, while still working with <% jard %>. Internally, ERB compiles the view template into a series of Ruby print statements, then evaluate all the statement with an input binding. This is a test file to point the differences between two approaches:

require 'erb'

str1 = <<-CODE
  <h1>
    <% jard %>
    <% a = 1 %>
  </h1>
CODE

puts ERB::Compiler.new(0).compile(str1).first.to_s
puts "==================="

str2 = <<-CODE
  <h2>
    <%= jard %>
    <% a = 1 %>
  </h2>
CODE
puts ERB::Compiler.new(0).compile(str2).first.to_s

Results:

#coding:UTF-8
print "  <h1>\n    ".freeze
;  jard ; print "\n    ".freeze
;  a = 1 ; print "\n  </h1>\n".freeze

===================
#coding:UTF-8
print "  <h2>\n    ".freeze
; print(( jard ).to_s); print "\n    ".freeze
;  a = 1 ; print "\n  </h2>\n".freeze

So, in the second script, jard is called as an an argument of print method call. Unfortunately, this case is not handled in latest version. This bug is fixed in #37.

Awesome thanks
