Rubyit

A command line program for evaluating erb templates.

View the Project on GitHub morganp/RubyIt

A command line utility for evaluating any file with Embedded Ruby (erb). Example scenarios include using the flexibility of ruby to build a web site but which is static and does not require a restful interface. It can be created using ruby then built to a static site. Lowering maintenance and production costs, as nginx can be used to serve static files.

Alternatively you could have a .rbashrc with switches for different Operating Systems this then builds to custom .bashrc files.

Templating for any text based document.

Installation

gem install ruby_it

Usage

Help:

$ ruby_it --help

Basic (all variables contained in the template):

$ ruby_it  --outpath ./ --file ./hellos.rtxt

Intermediate (command line variables):

$ ruby_it --parameter @hellos=10 --outpath ./ --file ./hellos.rtxt

Advanced (Specify a centralised config file used by multiple templates):

$ ruby_it --config hello.conf --outpath ./ --file ./hellos.rtxt

hello.conf

@hellos = 15

hellos.rtxt, file with erb

<% @hellos.times do -%>
<%= 'Hello' %>
<% end -%>

As part of a Ruby script

require 'ruby_it'

thing_var = 3
rubyit = RubyIt::Document.new("../templates/hellos.rtxt")
rubyit.add_parameter( "@hellos = #{thing_var}" )
rubyit.write

File Names

 .rbashrc  -> .bashrc

Since version 0.3.0 The template can change the output filename, by:

<% param = 1 -%>
<% $parent.out_filename = "new_filename_#{param}.log" -%>
