Expression2, beta patch release (help with testing)

[Syranide]

UPDATE2: Another patch.
UPDATE1: Forgot to add typechecker.lua to the patch, new patch has been uploaded.


For those unaware of what this is: E2=c^2 (expression2)
This patch will cause expressions to compile into native Lua, meaning you should see quite a performance improvement for many purposes (when it is finished).



So here's the first version of the patch, everything should compile properly into Lua, it should be almost 100% backwards-compatible with all extensions. But most of the core-extensions have not yet been rewritten to make use of the new native functions, meaning the performance is currently about the same.

So please, apply the patch to your wiremod, try out your old expressions and make sure they work properly, when you're done you can just right-click the wiremod addon and use "revert" to restore it. Make sure you have access to the console (add "-console" to the launch parameters in steam).



Known issues:
- OPS/PERFORMANCE MONITORING IS NOT YET IMPLEMENTED ... expressions that rely on opscounter()/minquota()/maxquota() to restrict performance will not work.
- changed(*) works, but it may work incorrectly if you use it in many places.
- A ?: B is not yet implemented



If an expression errors, please provide the code and error message. I would be greatful if you could try to pin-point the problem yourself, almost all errors that can occur are caused by a single instruction, meaning, remove large sections of code until you basically just get a few lines of code left that still causes the error.

If the expression behaves improperly, please make sure it's not caused by one of the above known issues and then post code, what's wrong and if possible what you think may be causing it.

(private messages is fine if you don't want to publish your code for others to see)

Some issues with the patch, I'll provide a new patch a bit later today that should work better!

tested it out, but i found something weird
with some sound chips i have on my computer
But when i spawn them it says infinite loop detected
In non-patch version it worked fine
i post one of them here (TETRIS)

Then the chip-s OPS doesn't work
always on 0 ops per second, even the most needy ones don't show any

So yeah, that's why you get the infinite loop and no ops.

But thanks!

Using clamp(NNN) gives me the following error when I spawn the E2, it validates fine:

entities\gmod_wire_expression2\core/e2lib.lua:576: attempt to call global 'ERROR' (a nil value)

Entire E2 code:

 clamp(1,2,3)

Edit:
Using exit() gives me:

Expression 2 (Stacker): unknown chunk:5: attempt to read from global scope error

I would have debugged, but it spammed me with

[ents.Create( "prop_physics" )] This frame you have created 148871136 entities! (Lua Error!?)

Until my client crashed with no errors.

[Whosdr]

Bump due to no reply above.

[Whosdr]

Bump...again.
Could I have a reply to this, just to say you've seen it or something?

[Drunkie]

I'm curious, how is this coming along, will it be committed soon?

[Syranide]

Sorry everyone, I got really busy around the time I posted that patch and haven't really had any time since then. There has not been any further progress due to time and motivation. So I'm sad to say that it's currently on ice, it's mostly in a working state, but there's a couple of new features that has to be added to before it's safe for the public, one being benchmarking all functions/operators which I'm not even quite sure how to do reliably at the moment.
