Question

我试图设置Liquid gem，以便它不会引发语法错误的异常。根据{{3}}，您可以设置不同的错误模式，如果设置了lax，它应该接受几乎任何＆＃34;＆＃34;并且不会提出任何例外。即使我设置了该模式，也会引发异常，例如：

1.9.3-p551 :041 > Liquid::Template.error_mode = :lax
 => :lax
1.9.3-p551 :042 > Liquid::Template.error_mode
 => :lax
1.9.3-p551 :043 > Liquid::Template.parse("Thank you for your purchase at {{shop_name}")
Liquid::SyntaxError: Liquid syntax error: Variable '{{shop_name}' was not properly terminated with regexp: /\}\}/
    from /Users/david/.rvm/gems/ruby-1.9.3-p551/gems/liquid-3.0.6/lib/liquid/block.rb:104:in `create_variable'
    from /Users/david/.rvm/gems/ruby-1.9.3-p551/gems/liquid-3.0.6/lib/liquid/block.rb:44:in `parse'

    from script/rails:6:in `<main>'

我错过了什么？

Answer 1

似乎你错过了第二个}。

而不是

Liquid::Template.parse("Thank you for your purchase at {{shop_name}")

尝试

Liquid::Template.parse("Thank you for your purchase at {{shop_name}}")

Answer 2

它实际上是expected behavior，在这种情况下你不能避免Liquid提出异常。（以防万一有人遇到同样的问题，我没有关闭这个问题）

在松弛模式下液体引发SyntaxError
