ERBX - ERB Extended with Pretty Tags
ERBX is a tiny extension to ERB allowing these tags:
-
{{ ... }}
as an equivalent to<%= ... %>
(print ruby code) -
(( ... ))
as an equivalent to<%- ... -%>
(run ruby code)
Both tag pairs are configurable.
Installation
$ gem install erbx
Usage
Given this ERBX templalte:
# example/template.md
((
# Any ruby code can go here
today = Time.now.strftime "%B %d, %Y"
dice = [rand(6) + 1, rand(6) + 1]
))
This roll of a dice happened on {{ today }}.
(( if dice[0] == dice[1] ))
Congratulations, its a double: {{ dice }}
(( else ))
You rolled {{ dice }}
(( end ))
Render it with ERBX.new
, which returns an ERB
instance, after replacing
the extended tags - {{ }}
and (( ))
- with their ERB
equivalents.
# Render example
require 'erbx'
template = ERBX.load 'example/template.md'
p template.class
#=> ERB
puts template.result
#=>
#=> This roll of a dice happened on April 24, 2020.
#=> You rolled [4, 2]
Custom Tags
If you wish to use different tags in your template, you can provide them using these four options:
-
code_open
- default((
-
code_close
- default))
-
output_open
- default{{
-
output_close
- default}}
For example:
# Render example with options
require 'erbx'
template = ERBX.load 'example/template2.md', code_open: '===[', code_close: ']==='
puts template.result_with_hash number: rand(100..999)
#=> This template only uses output tags, and uses data provided by the caller.
#=> This is useful when the file may contain (( markers like these )) that are
#=> not intended to be interpreted as code.
#=>
#=> Random number: 938
