Anyone ever noticed that if you make a script with a function named 'print' it wont compile?
Since when has 'print' been a reserved word in LSL? And why?
I reported it as a bug but no one ever got back to me.

They haven't gotten back to me on any bugs in about two, maybe three weeks (at least). LL seems to have dropped off the face of the earth.

well 1.5.5 had less cleaning done then previous releases have had done; viewerart.ini has keys to test trees in it.

NECROPOST!!

Somebody over in FlogAnswers just asked about what 'print' does in LSL and I stumbled over this old post..

It seems to be an event/callback but I don't see any docs on it. Anybody know?

Well since "Hi" compiles too without print(), (see my title) I woudln't have too much hopes.

It returns a key/string which is equal to NULL_KEY, but that doesn't work with Mono, only old LSL.

that is an odd bit of code... the word print should be generating a compile error, but I guess that it's part of the functions naming... I know at one point it was possible to name functions to the same name as the internal event calls (which are compiled as functions) and actually directly call events as a user function... this may just be more of that exposed...

Good friends, old friends :(

I forgot this thread existed, even posting to it. Wish I had remembered when the article on the LSL Portal was written (would have saved me a bit of face). Should checkout the example I wrote for it (I'm bad :p)

https://wiki.secondlife.com/wiki/Print

Oh and "print" support was almost dropped in Mono, but I found out and "saved" it. :D

Oops.. Somehow missed finding that one..

Do we know where stdout actuall goes? Hopefully not to a log file on the sim.

edit: and how do/did you know it went to stdout? Was that from a guess or from inside info? :)

Erk, sounds like you could DOS a server with this baby if it actually works.

In my insanity I think it'd be amusing to send notes to LL with this...

"Hi, I R in your server, spamming your logs"

Unlike the ll* functions for which we do not have the source code for, we do have the source code for the rest of the VM and compiler. As it turns out "print" is not a function but actually a bytecode (in LSO) and it's implementation can be found in the viewer source.

When it was pointed out to me that "print" was a compiler token, I started walking the compiler source looking at what it did. I too was surprised by the implementation.

printf to the rescue :D

As to the mono implemenation, I cannot speak.

All I can say is that it first casts the argument to a string, and then sends the result off to:
[LslLibrary]LindenLab.SecondLife.Library::Print(string)

I've never seen the source for "LindenLab.SecondLife.Library"... I'd like to.

It would be pretty pointless otherwise.

What I wonder is if all messages produced by the simulator go to the same log file. If they do you could use "print" to forge log messages. I wouldn't be surprised if there are several services that watch the log files for certain events (like why did the simulator crash). Without insider information you wouldn't be able to know but if you did have said information you might be able to crash or own the service. In the latter case you could open up a hell mouth and let demons take over the world.

lol I only mentioned it because stdout is usually the screen (well text terminal, but for general purposes... yeah)
