access outside variable in macro?

Question

how to access main namespace variable in macro?

I have a macro file called orderMacro.ftl, and import it in test.ftl like this:

<#import "path/orderMacro.ftl" as order/>

I also define a variable in test.ftl:

<#assign orderType="normal"/>

Now I access orderType variable in orderMacro using main.orderType, main means the namespace created for test.ftl(maybe I misunderstand this word). it reports an error: Expression main is undefined

Answer 1

You need to write .main.orderType. Note the initial dot. It's the syntax for accessing "special variables", so that they can't clash with other variables.

Answer 2

Assign it using global

<#global orderType="normal"/>
