# = ERB -- Ruby Templating

[17] Fix | Delete

#

[18] Fix | Delete

# == Introduction

[19] Fix | Delete

#

[20] Fix | Delete

# ERB provides an easy to use but powerful templating system for Ruby. Using

[21] Fix | Delete

# ERB, actual Ruby code can be added to any plain text document for the

[22] Fix | Delete

# purposes of generating document information details and/or flow control.

[23] Fix | Delete

#

[24] Fix | Delete

# A very simple example is this:

[25] Fix | Delete

#

[26] Fix | Delete

# require 'erb'

[27] Fix | Delete

#

[28] Fix | Delete

# x = 42

[29] Fix | Delete

# template = ERB.new <<-EOF

[30] Fix | Delete

# The value of x is: <%= x %>

[31] Fix | Delete

# EOF

[32] Fix | Delete

# puts template.result(binding)

[33] Fix | Delete

#

[34] Fix | Delete

# <em>Prints:</em> The value of x is: 42

[35] Fix | Delete

#

[36] Fix | Delete

# More complex examples are given below.

[37] Fix | Delete

#

[38] Fix | Delete

#

[39] Fix | Delete

# == Recognized Tags

[40] Fix | Delete

#

[41] Fix | Delete

# ERB recognizes certain tags in the provided template and converts them based

[42] Fix | Delete

# on the rules below:

[43] Fix | Delete

#

[44] Fix | Delete

# <% Ruby code -- inline with output %>

[45] Fix | Delete

# <%= Ruby expression -- replace with result %>

[46] Fix | Delete

# <%# comment -- ignored -- useful in testing %>

[47] Fix | Delete

# % a line of Ruby code -- treated as <% line %> (optional -- see ERB.new)

[48] Fix | Delete

# %% replaced with % if first thing on a line and % processing is used

[49] Fix | Delete

# <%% or %%> -- replace with <% or %> respectively

[50] Fix | Delete

#

[51] Fix | Delete

# All other text is passed through ERB filtering unchanged.

[52] Fix | Delete

#

[53] Fix | Delete

#

[54] Fix | Delete

# == Options

[55] Fix | Delete

#

[56] Fix | Delete

# There are several settings you can change when you use ERB:

[57] Fix | Delete

# * the nature of the tags that are recognized;

[58] Fix | Delete

# * the value of <tt>$SAFE</tt> under which the template is run;

[59] Fix | Delete

# * the binding used to resolve local variables in the template.

[60] Fix | Delete

#

[61] Fix | Delete

# See the ERB.new and ERB#result methods for more detail.

[62] Fix | Delete

#

[63] Fix | Delete

# == Character encodings

[64] Fix | Delete

#

[65] Fix | Delete

# ERB (or Ruby code generated by ERB) returns a string in the same

[66] Fix | Delete

# character encoding as the input string. When the input string has

[67] Fix | Delete

# a magic comment, however, it returns a string in the encoding specified

[68] Fix | Delete

# by the magic comment.

[69] Fix | Delete

#

[70] Fix | Delete

# # -*- coding: utf-8 -*-

[71] Fix | Delete

# require 'erb'

[72] Fix | Delete

#

[73] Fix | Delete

# template = ERB.new <<EOF

[74] Fix | Delete

# <%#-*- coding: Big5 -*-%>

[75] Fix | Delete

# \_\_ENCODING\_\_ is <%= \_\_ENCODING\_\_ %>.

[76] Fix | Delete

# EOF

[77] Fix | Delete

# puts template.result

[78] Fix | Delete

#

[79] Fix | Delete

# <em>Prints:</em> \_\_ENCODING\_\_ is Big5.

# == Examples

[83] Fix | Delete

#

[84] Fix | Delete

# === Plain Text

[85] Fix | Delete

#

[86] Fix | Delete

# ERB is useful for any generic templating situation. Note that in this example, we use the

[87] Fix | Delete

# convenient "% at start of line" tag, and we quote the template literally with

[88] Fix | Delete

# <tt>%q{...}</tt> to avoid trouble with the backslash.

# == Notes

[248] Fix | Delete

#

[249] Fix | Delete

# There are a variety of templating solutions available in various Ruby projects:

[250] Fix | Delete

# * ERB's big brother, eRuby, works the same but is written in C for speed;

[251] Fix | Delete

# * Amrita (smart at producing HTML/XML);

[252] Fix | Delete

# * cs/Template (written in C for speed);

[253] Fix | Delete

# * RDoc, distributed with Ruby, uses its own template engine, which can be reused elsewhere;

[254] Fix | Delete

# * and others; search {RubyGems.org}[https://rubygems.org/] or

[255] Fix | Delete

# {The Ruby Toolbox}[https://www.ruby-toolbox.com/].

class ERB

# = ERB::Compiler

[272] Fix | Delete

#

[273] Fix | Delete

# Compiles ERB templates into Ruby code; the compiled code produces the

[274] Fix | Delete

# template result when evaluated. ERB::Compiler provides hooks to define how

[275] Fix | Delete

# generated output is handled.

[276] Fix | Delete

#

[277] Fix | Delete

# Internally ERB does something like this to generate the code returned by

[278] Fix | Delete

# ERB#src:

[279] Fix | Delete

#

[280] Fix | Delete

# compiler = ERB::Compiler.new('<>')

[281] Fix | Delete

# compiler.pre_cmd = ["_erbout=+''"]

[282] Fix | Delete

# compiler.put_cmd = "_erbout.<<"

[283] Fix | Delete

# compiler.insert_cmd = "_erbout.<<"

[284] Fix | Delete

# compiler.post_cmd = ["_erbout"]

[285] Fix | Delete

#

[286] Fix | Delete

# code, enc = compiler.compile("Got <%= obj %>!\n")

[287] Fix | Delete

# puts code

[288] Fix | Delete

#

[289] Fix | Delete

# <i>Generates</i>:

# #coding:UTF-8

# _erbout=+''; _erbout.<< "Got ".freeze; _erbout.<<(( obj ).to_s); _erbout.<< "!\n".freeze; _erbout

[293] Fix | Delete

#

[294] Fix | Delete

# By default the output is sent to the print method. For example:

[295] Fix | Delete

#

[296] Fix | Delete

# compiler = ERB::Compiler.new('<>')

[297] Fix | Delete

# code, enc = compiler.compile("Got <%= obj %>!\n")

# #coding:UTF-8
