So I would like to get my eggdrop to parse a file continually. And if a string/regexp matches then follow up with some action.
The follow up is easy - just not sure how to scan.
Thanks in advance. |

Hi there. Sounds like you are wanting to either output the whole file line by line, or else create a list containing each line. To do the first, you can do do something like this:
| Code: |
set fs [open "file.ext"]
while {[gets $fs line] >= 0} {
<actions here>
}
close $fs
|
If you want to create a list of file line elements:
| Code: |
set fs [open "file.ext"]
set lines [split [read -nonewline $fs] \n]
close $fs
|
Be sure to close the file when you are done with it. Leaving one open and opening it again makes for a badly behaved eggie, hehe. |

| Thank for the reply. I was looking more for a tail -f script. In the end I went from a cron job. |

| Oh, okay, my bad... you could do something with the exec command also. You can put the command in as you would normally, just use exec before. |

fconfigure $fs -blocking 0 -buffering line
fileevent $fs readable [list output $fs]
proc output {fs} {putserv "privmsg #chan :[gets $fs]"} |
