Template:Trim

Template documentation[view] [edit] [history] [purge]

This template is used on 844,000+ pages.
To avoid large-scale disruption and unnecessary server load, any changes to it should first be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can then be added to this page in a single edit. Please consider discussing changes on the talk page before implementing them.

This template is for trimming whitespace from strings. For the maintenance tag for images, see {{trimming}}

This template trims leading and trailing (but not interior) whitespace from a string. The string should be passed as the first unnamed parameter. The parameter must be named |1= if its value contains a = character.

You may substitute this template - that is, if used as {{subst:trim}}, the resulting wikicode is "clean".

Usage[edit source]

{{trim|text}} = text with any leading or trailing whitespace removed.

Examples[edit source]

"{{trim| abc}}" produces "abc"
"{{trim|xyz }}" produces "xyz"
"{{trim| abc xyz }}" produces "abc xyz"
