need an error checking routine

I saw an error checking routine one time that really impressed me but I didn't write it down and now I can't remember what it was for the life of me. Anyway, what it did was catch errors in a tcl script, output them to the party line and then just not load that script, it wouldn't crash the bot.

I know that it was done using catch but can anyone help me with some code for this? I've been pulling my hair out for days trying to figure it out.

It's probably a replacement "source" command. I wrote one once, it's pretty simple. Rename the old source command to "old_source" or something, then make a new source command that does catch {old_source $scriptname} and reports errors.

yeah, it did sort of replace the source command but it was really just a catch for the source. I've got it catching the error so that it doesn't crash the bot, I am just not sure how to show the error in the party line.

The simplest method to show it in the partyline, is to issue a "putlog" with the variable storing the info.

I am wondering if you where on about an alternative to eggdrops timer command? As that only spits out "error in timerXXXX"?

ok, the putlog is working ... thanks

now the only problem is I don't know what variable stores the error message. Anybody?

EG

Code: Select all

catch {unknown_command} var1

The error msg is now stored in "var1"

this is what I finally came up with. It shows the error just like it normally would but it doesn't crash the bot.

Code: Select all

if { [catch {source scripts/dice.tcl}] } { putlog "Error in dice.tcln $errorInfo" }

just change dice.tcl with whatever script you are loading in both places.

Thanks for your help guys

I have a script that does what I was talking about earlier. That way you can use 'source' just like always and it still does the error catching and logging.

Just do: source scripts/safesource.tcl before you load any other scripts.

It would be nice if this was included with eggdrop by default, either via an option in the config to turn on, or the TCL included. I can't count the times I crashed my bot while trying to get a tcl working properly.
