使用Ruby生成格式化文件的方式与PHP如何完成

问题描述：

I use PHP to generate files of some special format, and I have decided to try the same thing with Ruby. To make a file with PHP, I use the following code:

<? include 'functions_and_settings.php'; ob_start() ?>

some parts of another format

<? // php functions generating file content, 
   // including other formatted files ?>

some parts

<? file_put_contents('output.fmt', ob_get_clean()) ?>

Is it possible to do with Ruby? How would you do this?

Update

The following code is equivalent to the PHP one:

require 'erb'
require 'my_functions_and_settings'
template = ERB.new <<-EOF

some text lines of another format

<% #functions generating content,
   # inclusion of formatted files %>

some text lines of another format

EOF
File.open("output.fmt", "w") do |f|
  f.puts template.result(binding)
end
# or may be:  File.new("file.txt") << template.result(binding)

Is there a way to do ruby file.erb >> output.fmt?

Update2

Standard Ruby distribution has erb processor

/usr/bin/erb  my_formatted_file.erb

我使用PHP生成一些特殊格式的文件，我决定尝试用Ruby做同样的事情。要使用PHP创建文件，我使用以下代码： p>

 ＆lt;？ 包括'functions_and_settings.php';  ob_start（）？＆gt; 
 
some另一种格式的部分
 
＆lt;？  // php函数生成文件内容，
 //包括其他格式化文件？＆gt; 
 
some parts 
 
＆lt;？  file_put_contents（'output.fmt'，ob_get_clean（））？＆gt; 
  code>  pre> 
 
 是否可以使用Ruby？ 你会怎么做？ p> 
 
 

 更新 strong>  p> 
 
 
以下代码相当于 PHP one： p> 
 
 

  require'erb'
require'my_functions_and_settings'
 
mpmplate = ERB.new＆lt;＆lt; -EOF 
 
some另一种格式的文本行
 \  n＆lt;％#functions生成内容，
＃包含格式化文件％＆gt; 
 
some另一种格式的文本行
 
EOF 
File.open（“output.fmt”，“w”）do | f |  
 f.puts template.result（binding）
end 
＃或者可能是：File.new（“file.txt”）＆lt;＆lt;  template.result（binding）
  code>  pre> 
 
 有没有办法做 ruby file.erb＆gt;＆gt;  output.fmt  code>？ p> 
 
 

  Update2  strong>  p> 
 
 
标准Ruby发行版 erb  code> processor  p> 
 
 

  / usr / bin / erb my_formatted_file.erb 
  code>  pre> 
  div>

答

There are several ways to do this but the most common is probably erb. This allows you to provide a template and then embed ruby command within <% %> symbols. In much the same way as you do with PHP. This is how most Ruby-On-Rails applications render their views.

There is a short review of 19 different ruby templating engines (Some of which are XML/HTML specific) available here
