From Wikipedia, the free encyclopedia
This template uses Lua :
This template trims leading and trailing square brackets and whitespace from a string. This is similar to {{delink }}, but it won't remove brackets from the middle of the string. The string should be passed as the first unnamed parameter or using |1= if your string contains any = signs. You may substitute this template - that is, if used as {{subst:trim brackets }}, the resulting wikicode is "clean".
Usage {{trim brackets |text }} = text with any leading or trailing square brackets removed (as long as text doesn't contain any = signs).
{{trim brackets |1=text }} = text with any leading or trailing square brackets removed.
Example "{{trim brackets |1= [[abc]], [[def]], and [[ghi]] }}" produces "abc]], def , and [[ghi"{{delink |1= [[abc]], [[def]], and [[ghi]] }}" produces "abc, def, and ghi"). Template data Template parameters[ Edit template data ]
