Template:Strloc prefix
{{{1}}}
.svg){kind=link}
The string-prefixer Template:Strloc prefix gets the prefix of a string up to a specified location, or the entire string when location is less than 1.
Usage[change]
- {{Strloc prefix|<string1>|strloc=<n>}}
Returns the prefix of string1 up to location strloc=n, where n = 1 denotes the first character of the string. If strloc <= 0 then the entire string1 is the result. The parameter strloc can be a math formula, such as: strloc={{{len}}}-2, or strloc=abs(-2*5)+6.
Examples[change]
The following show various uses:
- {{Strloc prefix|abcdef|strloc=3}} → abc
- {{Strloc prefix|abcdef|strloc=0}} → abcdef
- {{Strloc prefix|My Title (film)|strloc= {{strfind_short|My Title (film)|(|1|lenstr={{strlen_quick|My Title (film)}}|}}-2}} → My Title
- In the example with "{{strfind_short}}: the number for strloc was set by finding "(" in the
title. If there had been no parenthesis "(" then the result would get the entire title.
Limitations[change]
The text extracted is subject to the limitations of parser functions {#ifexpr:} and {padleft:}. In particular, spaces around the prefixed string are dropped, and NOT counted, before or after:
- {{Strloc prefix| Title here |strloc=9}} → "Title her"
- {{Strloc prefix| Title here |strloc=0}} → "Title here"
Spaces embedded within the prefix string are real spaces (NOT " "), and any accented or special characters can be used in the string.
