= README for eRuby
== What's eRuby?
eRuby interprets a Ruby code embedded text file. For example, eRuby
enables you to embed a Ruby code to a HTML file.
== Required environment
* Ruby version 1.6.x or later.
== Installation
(1) Type `./configure.rb' to create Makefile.
(Type `./configure.rb --help' to get a help message.)
(2) Type `make' to compile eRuby.
(3) Type `make install' to install all files.
== Syntax
A Ruby block starts with `<%' and ends with `%>'. eRuby replaces
the block with its output.
$ cat foo
Hello, <% print "World!" %>
$ eruby foo
Hello, World!
If `<%' is followed by `=', eRuby replaces the block with a value
of the block.
$ cat bar
Hello, <%= "World!" %>
$ eruby bar
Hello, World!
If `<%' is followed by `#', the block is ignored as a comment.
$ cat baz
Hello,<%# this is
a comment %> World!
$ eruby baz
Hello, World!
If a line starts with '%', eRuby evaluates the line as a Ruby
program and replaces the line with its output.
$ cat quux
% x = 1 + 1
1 + 1 = <%= x %>
$ eruby quux
1 + 1 = 2
