What is ruby-erubi
ruby-erubi is:
Erubi is a ERB template engine for ruby. It is a simplified fork of Erubis, using the same basic algorithm, with the following differences:
- Handles postfix conditionals when using escaping (e.g. <%= foo if bar %>)
- Supports frozen_string_literal: true in templates via :freeze option
- Works with ruby’s –enable-frozen-string-literal option
- Automatically freezes strings for template text when ruby optimizes it (on ruby 2.1+)
- Escapes ’ (apostrophe) when escaping for better XSS protection
- Has 6x faster escaping on ruby 2.3+ by using cgi/escape
- Has 86% smaller memory footprint
- Does no monkey patching (Erubis adds a method to Kernel)
- Uses an immutable design (all options passed to the constructor, which returns a frozen object)
- Has simpler internals (1 file, <150 lines of code)
