Template:Trim leading

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

UsageEdit

{{Trim leading|<input> |<prefix> }}

Trims up to six instances of <prefix> (such as: 0 or "anti-") from the beginning of <input>. <Prefix> is set to "0" by default (for removing leading zeroes from numbers). Template will not properly work beyond the first whitespace in the input.

LimitationsEdit

  • Up to 100 chararacters in the input string. If possible, first check length of input string using {{Str len}}. Using strings longer than 100 characters may result in the error "max index is 100 for str_sub".
  • Limited set of characters.
  • Snags on whitespace.
  • Expensive.

ExamplesEdit

{{Trim leading|00000034 }} → 34

{{Trim leading|U+0034|U+}} → 0034

{{Trim leading|anti-anti-neutrino |anti-}} → neutrino
