fileevent $::fd readable recvdavou I've edited the function roll_formatter down so that it's much shorter... I've gotten the bot to connect to IRC, and join the channel mentioned in $::chan, but it leaves just as fast as it gets in... does anyone know why it's doing this? - RS: Easiest way to find out is to add puts $line right after the gets $::fp line and see what comes in.
Just a few comments on the Tcl usage...No need to nest the expr's in:
set ::me "dicebot_[expr round([expr rand() * 10000])]" return [expr round([expr rand() * $sides])]Just do:
set ::me "dicebot_[expr round(rand() * 10000)]" return [expr round(rand() * $sides)]Also:
set incriment 0
set rolled "$name rolled"
set total 0
while {$incriment != $number} {
append rolled " "
set temp [random $sides]
append rolled $temp
incr incriment
set total [expr $temp+$total]
}This looks awfully like it should be a for loop. Also, the double append is redundant:
set total 0
for {set i 0 } { $i < $number } { incr i } {
set rolled "$name rolled"
set temp [random $sides]
append rolled " $temp"
set total [expr $temp+$total]
}And lastly, I believe your random proc contains an error - its return value is 0 to $sides rather than 1 to $sides, so maybe use:
proc random {sides} {
return [expr int(rand() * $sides) + 1]
}instead?Lars H: A few more comments on the Tcl usage (and the comments upon that). First, it probably doesn't make much difference in this case, but will generally be better off if you make it a habit to brace your expr-essions. Second, instead of combining append rolled " "
append rolled $tempintoappend rolled " $temp"it may be better to combine it into
append rolled " " $tempThe difference is that the middle command copies the contents of $temp twice: once to build the string $temp-with-a-space-in-front and a second time when appending that to $rolled. The difference is negligible when $temp is short, but can be noticed in cases where $temp is very long. (Giving append several arguments also reduces the nesting in the code, which can sometimes make it easier to read.)The two lines
set room [split $line #] ; set room [lindex $room 1] ; set room [split $room " "] ; set room "#[lindex $room 0]"
set room [split $line #] ; set room [lindex $room 1] ; set room [split $room " "] ; set room "#[lindex $room 0]"also seem rather strange. The second seems entirely redundant and the first (grabbing what's between the first # and the first space thereafter) could probably be more easily expressed using regexp. If you want to keep using split and lindex, then consider combining them, like so:set room [lindex [split $line #] 1] ; set room "#[lindex [split $room " "] 0]"The cost for setting variables is not always negligible.
Yeah, you're absolutely right about the split/combined append:
#!/bin/env tclsh
set max [lindex $argv 0]
proc testSplit { } {
global mystr
set addstr "x"
append addstr " " $mystr
}
proc testComb { } {
global mystr
set addstr "x"
append addstr " $mystr"
}
for { set i 0 } { $i < 1048576 } { incr i } {
append origstr "x"
}
set mystr $origstr
puts "testSplit : [time testSplit $max]"
set mystr $origstr
puts "testComb : [time testComb $max]"Running it under Tcl8.0 gives:$ ./testAppend 1000 testSplit : 1034 microseconds per iteration testComb : 2238 microseconds per iterationAnd again under Tcl8.4:
$ ./testAppend 1000 testSplit : 1051 microseconds per iteration testComb : 2331 microseconds per iterationSo the overhead for the combined approach doubles the running time.
