v4.59pre3 - December 23 2013

[Justin]

v4.59pre3 - December 23 2013

• JS: safer file_string() in @serialize for unexpected data
• JS: fixed syntax highlight for old char syntax
• JS: gfx_printf \r handled better
• Render: VU meter display up to 16 channels for multichannel renders
• JS: improved string support (fixed certain escape sequences, etc)
• JS: big EEL frontend parsing overhaul, better error messages

The JS updates in this build represent a large overhaul of the frontend of the language compiler -- previously (last year, I forget?) we had improved the code generation and added optimization.. This updates the parser to be more modern and maintainable. I tested it against most of the code in the JS library thread, and there were only three plugins which were affected: IX MIDI_latch, Jonas DrumReaplacer, and SerialKiller. In each case, there was the following:

 status == statNoteOn || status = statNoteOff ?

This is an obvious typo, the "status = statNoteOff" should be "status == statNoteOff". Previously this was parsed as:

(status == statNoteOn || (status = statNoteOff)) ? ( ... )

and now it is parsed as:

(status == statNoteOn) || status = (statNoteOff ? ( ...))

...which is a big change, however the old parsing was incredibly inconsistent and really has no use, and is just plain wrong, and the fact that it only occurs in this typo is a pretty comforting change. These affected plug-ins likely did not function as intended as a result, but their behaviors may change from this update and they should be updated accordingly.

If you have other unreleased code that is affected, please let me know! Or if you want to know if your code is affected, I can test it (via verification code) for you.

Gooood !
I suppose that it will be extended to the full used channels number later ?

(EDIT) Perhaps could you use vertical meters when more than 16 ?
And a little number together each channel would also help.

Hallelujah! Control flaw (sic) was indeed hairy. Testing.

Awesome! While you're on this can we also get separate sets of meters for when we're rendering multiple stems

[plamuk]

question, how does this impact ReaJS?

i need to remember to update SerialKiller, but it's only used externally in bidule via reajs

Try

label[3] =$'d'; label[4] =$'\'; label[5] =$'Z';

\ are now parsed OK.

Ooops! My bad! Funny how errors can propagate like that.

I get crashes with some js plugins included, on this pre(4.59pre3) on x64 I get a instant crash when inserting fairlychildish2. The plugin doesn't crash the 32 bit version of this pre though. I also get crashes randomly while moving js plugin parameters and even after pressing stop pause or play sometimes, but it's hard to reproduce 100%.

That seems to be a divide by zero bug in fairlychildish2.
It crashes also in Reaper 4.581 x64. And it does not crash if fairlychildish2 is used alone, but for example with Poise VSTi it will crash immediately.

I have fixed similar bugs in Sequencer baby.

Justin, could you explain why divide by zero in JS plugins will produce crashes only in Reaper x64?

I'm glad you mentioned that because I am also using poise in combination.

Not disappointed.

BUG in this version:
Always when I click render for the first time the render dialogue just disappears, second time it works.

Got it, my guess is Poise is leaving divide by 0 exceptions on in the FPU flags, ugh. Fixing.

Not sure if you've seen this topic Justin (something I discovered in the previous pre where peaks subfolders were introduced) but hoping it is an easy fix.... http://forum.cockos.com/showthread.php?t=132854

[Argitoth]

uhh... yeahh... no else one tested this?
-I do not click cancel, my mouse just happened to hover over it, revealing it
-the output is correct
-reaper becomes unresponsive after exporting completes.

Edit: for being an exciting feature, not sure how no one bothered to test!

The bug only affects region renders. Fixed for the next build.
