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