Unclear behaviour of ".]" in WALTER

DrTT · 05-14-2022, 01:39 PM

Dear all,

I am experimenting with WALTER and I have found another small inconvenience.

When a tuple ends in ".]", this should normally mean that the existing scalar value of the target variable at that position is reused.

E.g. the code

Code:

    set tcp.mute [. . . .]

should do nothing (assuming that there are no stretch values in the definition of tcp.mute).

But it does not work; presumably the height is set to 0. As opposed to it the following works:

Code:

    set tcp.mute [. . . . ]

So the WALTER parser finds something I do not understand.

Or have I completely missed something?

Best regards,
DrTT

Ah yes, this is a bug. Need to evaluate how fixing will break things... for now definitely just use a space between the . and ] :/

Hello Justin,

thanks for your quick reaction! I am - of course - honored that the grandmaster is personally joining in.

While you're looking at WALTER mechanisms you might also consider my enhancement request in thread https://forum.cockos.com/showthread.php?t=266618 about scalar and tuple values.

I think that WALTER has an undeserved bad reputation for being overly complicated and any simplification would make the access for theme designers easier.

Best regards,
DrTT
