Saving the results of Eruby::import in a string instead of just printing them?

Does anybody know if it’s possible to have Eruby::import return its
output as a string instead of just printing it to stdout? I’d like to
be able to call it like this:

result = Eruby::import (‘inc/rhtml/template.rhtml’)

I suppose I could just backticks or something but I’d rather not take
on the overhead. Anybody managed to do this?

Thanks,

Francis

Use a class ‘ERuby::Compiler’.
This class has following instance methods:

  • compile_file(File)
  • compile_string(String)

Example:

··· 
require 'eruby'
filename = 'hoge.rhtml'
compiler = ERuby::Compiler.new()
src = nil
File.open(filename) do |file|
    src = compiler.compile_file(file)
end
print src
--------------------

--------------------
require 'eruby'
filename = 'hoge.rhtml'
file_str = nil
File.open(filename) do |file|
  file_str = file.read()
end
compiler = ERuby::Compiler.new()
src = compiler.compile_string(file_str)
print src
--------------------
