Калып:Strloc prefix/doc

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

{{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

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

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 "&#32;"), and any accented or special characters can be used in the string.

See also

• {{Strfind short}} - can be used to set strloc and default to whole string
• {{Strlen short}} - gets length of a short string (faster than {str len} )
• {{Strloc insert}} - inserts text at strloc, which can be set by {strfind_short}
