ERB, modified (slightly) for MRuby.
- Anywhere CRuby used binding arguments, mruby-erb accepts an object.
- The template is
instance_evaled on the object, instead of being
evaled in the context of a binding.
- No ERB::Util (CGI stuff... you don't need it).
- No encodings support (MRuby has limited support for this in general).
Depends on some regexp implementation. By default, mruby-regexp-pcre is used.
You can override this choice by setting the
MRUBY_REGEXP_GEM environmnet variable.
This should hopefully eliminate the need to fork this gem for each regexp implementation.
# Compile an ERB template. # - safe_level is here for API compatability only, and is not used. # - The rest is exactly what you're used to from CRuby template = ERB.new(str, safe_level[=nil], trim_mode[=nil], eoutvar[='_erbout']) # Execute a template and return the resulting string. # Accepts an object, rather than a binding. template.result(obj[=nil]) # Define `methodname` as instance method of `mod` from compiled ruby source. template.def_method(mod, methodname, fname[='(ERB)']) # Define module with methodname as an instance method from compiled ruby source. template.def_module(methodname[='erb']) # Define class with methodname as an instance method from compiled ruby source. template.def_class(superclass[=Object], methodname[='result']) ## Example: # tmp = "<%= a %> <%= b %>" # erb = ERB.new(tmp) # Renderer = erb.def_class(Object, 'render(a, b)') # renderer = Renderer.new # renderer.render(1, 2) # => "1 2"
