help with format

[slashem]

searched this forum and see some ppl referring to the format command, but I'm having major problems with it on using it right

I need to notice the users the following line several times:
| date | user | item
but user can be different each time, so the layout gets all messed up like:
| date | user1 | item
| date | user152 | item

how can I properly align it? plz

Code: Select all

putserv "notice $nick : | [lindex $something 0] | [lindex $something $1] | [lindex $something 2]"   

is what I have now..

Either use a fixed width (9 chars or whatever is your nick or handle length) of pass trough every element of the list looking for the longest. Then use that for formating length. I am not aware of any other way to do that except to script it as i said.

ok, say I wanna use a fixed width of 10 chars..
how do I apply that format function to it so that "bobby" becomes "bobby "...
or do I have to make a procedure for usernames that adds spaces?

OK - this is based on a single item, which has | at the start and end.

The list input will come from $nick, and the alignment is at 11 chars (IE, 10 chars between | and |).

Code: Select all

foreach a $nick {
  puts stdout "| ${a}[string repeat " " [expr 10 - [string length $a]]]|"
}

Doing it with the format command is a lot easier.

Code: Select all

set str [format "| %10s | %10s | %10s" [lindex $baa 0] [lindex $baa 1] [lindex $baa 2]]
putserv "notice $nick :$str"

Look up the format command in the tcl manual for more info on controlling the output, but basically for what you want, you do %XXXs, which means "a string XXX chars wide".
