i made a script to store newslines in a textfile. Everything works fine, add news, list news, and so on. But deleting a line doesn´t work. I have no idea how to solve that thing

Read the file, delete the line, write the file again.

I dont know how. I need an example because there is no command to delete a line in a textfile. Please give me an example.

Try this:

Code: Select all

proc deleteline {file line} {
  set fd [open $file r]
  set data [split [read $fd] "\n"]
  close $fd
  set data [lreplace $data [expr $line - 1] [expr $line - 1]]
  set fd [open $file w]
  puts $fd [join $data "\n"]
  close $fd
}

You might want to add -nonewline to your puts statement.

puts -nonewline ...

err, it was giving me an error, I swear! lol

something like "general error - could not find notify_email template"

so I hit reload.. I guess it was posting the whole time!

Well, now I can't delete them because your last message would be out of context

Hmm, I just received the same error when posting that. After looking up the error in the phpbb2 forums, I suspect anyone else who replies to this thread will run into the error, although the post will get through. Seems a lot of phpbb2 users are having this problem, but I couldn't see a fix.

Hmm, now the "last edited" message is showing up all of a sudden?
