Graphical formula editor

[Proektsoftbg]

I think that many engineers prefer MathCAD or SMath for the abillity to edit formulas graphically.
What about the Idea to put an "Insert formula" button in Calcpad? When you click it, to display a small formula editor window that allows you to input the formula in the same way as MathCAD/SMath. Then, clicking "Insert" to insert it into the current position inside your code.

It will be good if not only insert will work, i.e. editing existing formula will be allowed too

It seems necessary so much not because it is inconvenient to edit, but because fractions are not visually visible and it is difficult to keep track of parentheses. So - another way - like in Typora - show hint with rendered formula when caret inside it.

Although, a "pop-up" editor may be required to introduce matrices in the future.

As for personal experience: missing of a formula editor/hint annoys me not, but:

• slowdowns when editing large text even if autoupdate is off;
• intrusive autocomplete - well, here you need to know how many people want to press Ctrl+Space manually;
• lack of navigation to the source text (but only to the generated one) when macros are used (I understand that it's not trivial not only by realization - it's unclear how must it work in the interface).

Hi @cser! Thank you for your valuable comments. Yes, editing should be also an option.
BTW, I have good news for you. I managed to find why it works slow with large text and removed the bottleneck. This greatly improved the responsivness of the UI. Later today, I can upload a prerelease it you like to test it.

I also changed the way default values for input fileds are entered. Now they are in curly brackets after the question mark, e.g.:

a = ? {2}

This will make possible step by step solution with #pause and input fields in macros.

Sounds good

@cser Sorry, I could not manage yesterday. Please, try this prelease version:

https://github.com/Proektsoftbg/Calcpad/releases/tag/v5.9.0

I made some improvements on performance and UI responsiveness. It also works on .NET 7 already, so please install this as well:

[cser]

Oook, I'll try to test it tomorrow

[cser]

About v5.9.0: #include logic is broken (or changed?), this shows errors now:

#def INITIAL_1$
    x = 10
#end def
#include subfile.cpd		

"subfile
INITIAL_1$

file_and_subfile.zip

Error in "INITIAL_1$" on line [[2](about:blank#0)]: Invalid macro identifier: 'INITIAL_1$'.

[cser]

About a = ? {2}: I try it and yes - it was a nice idea.

[cser]

About performance I can't say anything now - big calculation don't work now (is it "as planned"? - then I just rewrite it). About not big calculations - can't feel deference.

@cser I updated the release. You can check again. :)
