I'm using freemarker to generate a freemarker template. But I need some way to escape freemarker tags.
How would I escape a <#list> tag or a ${expression} ?

c (when used with numerical value) This built-in converts a number to string for a "computer language" as opposed to for human audience. That is, it formats with the rules that programming languages used to use, which is independent of all the locale and number format settings of FreeMarker.
If FreeMarker is formatted incorrectly within an email template, you may experience a render error when you attempt to send the email. If your email has a render error, it cannot be processed or sent out.
The has_content FunctionFreeMarker has built-in functions to detect for variables. The most common method of detecting for empty or null values uses the has_content function and the trim function. The has_content function is often used with another built-in FreeMarker function to detect for null values.
Comments: <#-- and --> Comments are similar to HTML comments, but they are delimited by <#-- and -->. Comments will be ignored by FreeMarker, and will not be written to the output.
You could also use: ${"$"}{expression} if you find the {} nesting confusing.
