Talk:Mono

Other languages

Here's a question about mono that the article doesn't address: Will scripters be limited to LSL or will they be able to code in C# or something else more Mono-like? --Steamy Latte 12:20, 22 January 2008 (PST)

Until LL can ensure that Mono is properly sandboxed and secure, the compiler will remain server side and the only language available will be LSL. -- Strife Onizuka 12:40, 23 January 2008 (PST)

That makes total sense. Your comment does make it sound like there's a future plan to add other languages, after adequate testing has taken place. If so it's good news, as LSL lacks OOP and is cumbersome by comparison. --Steamy Latte 09:53, 24 January 2008 (PST)

In 16k you don't want OOP. Trust me. The overhead would be killer. I just want pass by reference. Pass by value is the worst feature of LSO. If I had to guess I would say that most of speed improvements come from pass by reference alone. -- Strife Onizuka 17:19, 24 January 2008 (PST)

Agreed! We would be able to leverage so much more from the sad 16kb we get if we could do address operations and pass by reference. Oh, a second question there. Will the maximum size of scripts be increased? Jana Kamachi 09:55, 26 January 2008 (PST)

I don't know. One advantage of the new system is that script asset transfers will be faster for the vast majority of script, they won't be statically allocated to 16kb. This means sim crossings should be faster. -- Strife Onizuka 15:56, 26 January 2008 (PST)

You sure? Serializing a mono script is a lot more work than serializing an LSL2 script, because the LSL2 script is basically serialized already. My concern has been that the cost of sim crossings with Mono scripts would likely be *higher*. I notice that in the Mono demos the Lindens have not shown a sim crossing for an avatar running Mono scripts: Babbage turned around before the edge of the sim in the one scene that looked like he might venture one. I hope they have multiple *adjacent* Mono-enabled sims in Beta. -- Argent Stonecutter 12:25, 28 January 2008 (PST)

Good point, I hadn't taken that into consideration. But if the script is a slave script without globals and not currently in an event that it won't have a stack or variables allocated. It should result in very little that needs serializing. I'm curious which system has a faster serialization of the event queue. -- Strife Onizuka 16:21, 28 January 2008 (PST)

Compile Data Flow

Can someone describe the way the current flow works, and how the new flow will contrast. That is, I think at present:

1. You edit on the viewer.
2. When you [save], the source is uploaded.
3. A compiler in the viewer creates bytecode.
4. The bytecode is uploaded.

Is this correct? How will this change, if at all? Lee Ponzu 09:20, 26 January 2008 (PST)

I can't be sure of this but the new system would be:

1. You edit on the viewer.
2. When you [save] and check the Mono checkbox, the source is uploaded.
3. Upon receiving the script some server (sim or centralized compiler?) compiles the script to CIL bytecode.
4. The bytecode is saved.

Is Mono just a compiler instead of Language ?

My understanding is that Mono just is a compiler instead of Language as LSL. After Mono is applied all over the main grid, residents still input LSL and check 'Mono' box, it's Mono that exchange the information between LSL and the server. Is this correct?
