exec in backround/with callback possible?

2006-02-26T21:54:03-04:00

Thank you, but i know how open | and exec work. =) My code works already on unix/eggdrop system without problems.

My tests:

- with unix: eggdrop 1.6.17 - working fine
channelid`s like file3

- with unix: tclsh - working fine
channelid`s like file3

- with windows xp: windrop 1.6.17 - Tcl error: couldn't create error file for command: no such file or directory

- with windows xp: 1.6.18cvs - Tcl error: couldn't create error file for command: no such file or directory

- with windows xp: 1.6.16 - working fine
(but this version is outdated, i don`t really want to use it)
the channelid`s are like file107e0560

the incomprehensible was that this (from bgExec):
set redir [expr {[info patchlevel] >= "8.4.7"?{2>@1}:{2>@stdout}}]
if [catch {open "| $prog $redir" r} pH] {
will work with windrop 1.6.17 and 1.6.18cvs [but for read acess mode r only :/].

I think the problem is about the windrop/cygwin/tcl version? Is there another solution then using windrop 1.6.16?

DeKus: May I pm you on irc?

you can savely delete them for your script. > changes the default output (stdout) which is usually the console (which you read from with gets/read). example from tclsh console:

Code:

~$ tclsh% open "| uname" rfile3% read file3Linux% close file3%

I hope you will understand now better how it works. Don't forget to use fileevent for true asyncronous acces (this above is syncron, too).
So dont forget to save the return value of open, because you will need it to read from .

The temp path is correct (otherwise the bot won`t start).

from here: http://wiki.tcl.tk/12704 (is working anyway, eggdrop just doesn`t have the command auto_execok)

Code:

set redir [expr {[info patchlevel] >= "8.4.7"?{2>@1}:{2>@stdout}}]if [catch {open "| $prog $redir" r} pH] {

i wonder that i can open and execute something on that way. but i don`t really understand why. could someone explain what these changes do?
2>@1
2>@stdout

check your temp-path and if you have c:\tmp; also check the FAQ at windrop's website

or wait for DeKus, he's our windrop guru; I personally have never used the thing, Windows is desktop OS to me

i got it from here
http://windrop.sourceforge.net/downloads.html

before i got Eggdrop v1.6.17 Handlen32 (08.07.2005)

and now i`ve updated to Eggdrop v1.6.18+spelling-errors-suck Handlen32 (25.12.2005)
info tclversion 8.4
info patchlevel 8.4.12

the error still comes up.
it`s not cause i use handlen32 version? (i doub`t that this has anything to do with it)

btw: what means "spelling-errors-suck"?

You'll need to find the appropriate ported Unix tools to use with Windrop or install cygwin and compile them yourself. The tool(s) are then copied into your Windrop main folder.

My failure, i forgot to add thats about windrop.

exec and open |
will always return an error like:
Tcl error: couldn't create error file for command: no such file or directory

Is it possible to fix that?

EDIT:
BgExec ( http://wiki.tcl.tk/12704 ) won`t work too, cause the mainproc is going to use open | aswell too.

Is there any way to execute something (windrop)?

search for "tail -f"

You can use

Code:

open "|"

instead, which is supposed to do the same without waiting like exec does.

A forum search on the topic will result in great information about it. Also, you can take a look at bgexec.tcl by strikelight which does what you want.

Hey

I want a eggdrop to start a external application. Exec wait`s until the prozess ends and will block anything else. Thats what i want to prevent. Is there a way to start a process and to get a callback after it?

best regards
sKy
