--
-- NOTE A1: This template counts the length of string {1} by
--      comparing with the string truncated to 'n' long in a
--      #switch for each set of lengths of {padleft:|n|{1} }.
--      The first match will exit the #switch with the length
--      number and exit the nested end-ifs. Max length is 70.
--
-- NOTE N2: This template was designed to use minimal levels
--      as 5, to avoid the "expansion depth limit" when used
--      in very large templates. By comparison, {str_len} was
--      using over 9-13 levels of 40 total, during 2009-2011.
--
-- NOTE P3: To speed the results, the check for length is based
--      on probability of an average length of 17/18, as found
--      in Wikipedia titles, where length 5 is as rare as 31
--      or longer. The average search is 6.5 uses of {padleft}
--      but the weighted average for actual titles is near 4.
--      When most strings are > 49, then use {str_len}.
--
-- NOTE S4: This template CANNOT be subst-substituted by using
--      {{subst:strlen_short|...}} to save only the results, or
--      {{{{{|safesubst:}}}strlen_short}} using blank parameter.

--HISTORY:

The '''[[Template:Strlen_quick]]''' gives the length of parameter 1, as a string, with a count of 0-70 characters, using a simple, quick method. The template was designed to run quickly and use only 5 levels of expansion depth, rather than 9-13 or more levels as in other string-length templates.

:'''Usage:''' &nbsp;{&#123;'''strlen quick'''|abcdef}} {{in5}} &rarr; 6
::: {&#123;'''strlen quick'''|123456789.}} &rarr; {{strlen quick|123456789.}}
::: {&#123;'''strlen quick'''|2.4| extra= -1}} &rarr; {{strlen quick|2.4| extra= -1}}

The optional parameter "extra= -1" can be used to return a specific value when a string exceeds the 70-character limit. The default result is -1 to indicate a string longer than 70 characters.

==See also==
* {&#123;[[Template:Strlen_short|Strlen_short]]}} - to get short string lengths (most < 10) but allow 0-50 at expansion depth of 3.
* {&#123;[[Template:Str len|Str len]]}} - handles strings up to 500 long, but with expansion depth 9-13 or more.
