Template:Str index any

Template documentation

The Template:str_index_any extracts a specified nth character from a string, even allowing for accented letters or diacritics to be included in the string. The string can be any length, but position n (parameter 2) is limited to 500 at most.

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 or other diacritical marks. Returns an error message for unknown characters. Returns   for a blank space, which can be converted to a simple space by xspace.

Examples

• {{ Str index any |0123456789ABCDEF|15}} → E
• {{ Str index any |ÁBĆĎÉf-ABCDEF|4}} → Ď
• {{ Str index any |Very very...long string of 500 characteRs|499}} → R
• {{ Str len |{{ Str index any |a b|1}}}} → 1
• {{ Str len |{{ Str index any |a b|2}}}} → 5
• {{ 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 5 for the 5 characters " " even though there is only 1 space, and hence, {{str len| }} → 5. 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}}>}} → 7
• {{ Str len |X{{ Str index any |a b|2}}X}} → 7
• {{ 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.

Easy to use and efficient string length comparison templates:

• {{str ≥ len}} – To check if a string is "longer or equally long" vs. "shorter" than a given length.
• {{str ≤ len}} – To check if a string is "shorter or equally long" vs. "longer" than a given length.
• {{str ≠ len}} – To check if a string is "not equal" vs. "equal" to a given length.
• {{str ≤ ≥ len}} – To check all three of "shorter", "equal" and "longer" at the same time.

Much less efficient string length template:

• {{str len}} – Takes a string as parameter and returns its length. Can count up to 500 in length.
