Eventually, the doc will be here: http://www.purl.org/tcl/home/man/tcl8.5/TclCmd/lsearch.html
lrepeat number element1 ?element2 element3 ...?
This command builds up a list by repeating elements. It will be a part of Tcl 8.5.0 . Note that Tcl 8.5 is available in an early developer form from ftp://ftp.tcl.tk/pub/tcl/nightly-cvs/tcl-*gz . Early access to Tk 8.5 is there as well.
An example of how it will work is
lrepeat 3 a a a a
RS: Note the possible confusion with string repeat's syntax:
% string repeat a 5 aaaaa
FW: The most minimalist way to implement this in straight Tcl for forwards-compatibility would in fact be to use string repeat:
proc lrepeat {number args} {string repeat "$args " $number}Or, for a more efficient solution:
proc lrepeat {number args} {
set res [list]
for {set i 0} {$i < $number} {incr i} {
concat res $args
}
}
