Partial executions in the %mathpiper fold?

[Peter]

Hello,

It would have been much better if I could "run" a set of partial
instructions in the %mathpiper fold. Can this be possible? Currently,
I move the ending %/mathpiper so that I can only hold the progressive
and constructive parts to be run.

What do you think about the idea of using \\ as the marker which
indicates where evaluation should stop in a fold? Here is an example:

%mathpiper

Echo(1);

Echo(2);

\\

Echo(3);

%/mathpiper

%output,preserve="false"
Result: True

Side Effects:
1
2

. %/output

Something like that seems useful, but ... 2 questions:

1.  As stated above, a line which contains only  //  terminates processing in the fold.  Then what happens with comments like
//
//    blah blah blah
//
?

2.  After processing of the fold stops, where does it "go"?  That is, what state will I find myself in?

FORGET THIS:  I MISREAD THE STATEMENT!    Not //   but \\.   OK!

Hello,

That will be a good idea. Again, it would be better for me to use a
"selection block of lines" for execution because that way I can always
pick necessary portion of the codes in the fold. It is still a good
idea to have such a "delimiter" to linearly segregate the code blocks,
though.

The way I am implementing the \\ behavior is after I grab the contents
of a fold as a string, I take a sub-string from it which starts at
offset 0 and goes up to, but not including, the \\. This sub-string is
then submitted to MathPiper for evaluation.

I will look into what it would take to do this.

I added the \\ "stop evaluation here" marker and "evaluation only of
selected code in a fold" to development version .79S:

Let me know how these work for you.

Hello,

Both new implementation for "partial execution" seem work so well.
If I extend my wish further I would say:
a "real" partial implementation would have been much better provided
that the jEdit editor allows "non-consecutive" selection (or, discrete
partial selection).
Is it possible?

Thank you for the version upgrading.

I have added multiple selection capabilities to version .79T:

Let me know what you think of it :-)
