Template:Str index any

Template documentation[ view · edit · history · purge ]

This documentation is transcluded from Template:Str index any/doc.

The Template:str_index_any extracts a specified nth character from a string, even allowing for accented letters to be included in the string.

Usage

{{str index any|text|n}} = Returns the n-th character of text.

Supports a larger character set, allowing the text to have accented letters. Returns an error message for unknown characters. Returns   for a blank space.

Relies on Module:String.

Examples

• {{ Str index any |0123456789ABCDEF|15}} → E
• {{ Str index any |ÁBĆĎÉf-ABCDEF|4}} → Ď
• {{ Str len |{{ Str index any |a b|1}}}} → 1
• {{ Str len |{{ Str index any |a b|2}}}} → 0
• {{ Str len |{{ Str index any |a b|3}}}} → 1

The last example shows extraction of letter "b" with string length as 1. The prior example extracts a blank but considers the length as 0, for there are no characters. If surrounded by 2 other characters, then the length might be totalled incorrectly as 7 (rather than 3 characters):

• {{ Str len |<{{ Str index any |a b|2}}>}} → 3
• {{ Str len |X{{ Str index any |a b|2}}X}} → 3
• {{ Str len |X{{ Str index |a b|2}}X}} → 7
• X{{ Str index any |a b|2}}X → X X

The same string-length problem occurs when using template {{Str index}}. There might be other quirks as well, but most cases work as expected.
