Richard Suchenwirth 2005-10-04 - "Ellipsis" is Greek for "left out". More specifically it's the name of the character(s) "..." (three ASCII periods, or fancier the Unicode \u2026) indicating that something was left out. When a string is truncated to fit into a given length, the following proc adds an ellipsis where necessary:
proc string'limit {str length} { expr {[string length $str]>$length? "[string range $str 0 [incr length -4]]..." : $str} } % string'limit hello 10 hello string'limit "hello long string" 10 hello l...
escargo 4 Oct 2005 - There are typographic rules for the use of ellipsis that make its use less than straightforward [L1 ].
JH - The string replace command is designed to do the ellipsis without otherwise modifying the string. Just use:
set str [string replace $str $length end ...]
If the string is already shorter than $length, it will not be touched.
