calque's Issues

Comments

Interesting tool, but I didn't find sign to comment line.
When you do many calculations, comments will help you understand what's happening

Dark theme

First of all, thanks, awesome project.

This is just a simple feature request. It would be even more awesome if you could implement dark colors that comforts prefers-color-scheme.

Value recalculates on text cursor moving

Try to use

randomInt(2, 500)

And press left / right arrows. Looks like a bug.

Use github-corners

https://github.com/tholman/github-corners

Current "Fork me on GitHub" ribbon is kind of outdated in my opinion. GitHub corners does a better job.

support for if/else operators

this would allow many other operations (e.g. recursion).

matrix, vector, limits

using ur calque every day but sometimes i need some things like matrix or derivative but there are no such things so im requesting it.
got some idea how to do matrix, use such counstruction like

A={
i, j, k ...
a, b, c ...
x, y, z ...
}
and fucs like det(A) or pow-1(A) would be also usefull for this

Add support for previous result

So it would be nice to chain calculations without creating variables for each result

2+2 ( = 4)
Ans + 2 ( = 6)  // or underscore like in Python

Is there a way to copy the result of an expression?

That would be practical.

Need ability to Cut&Paste with and without results of calcularion

Currently both Cut and Paste only works for the formulas themselves.
It would be nice to support 2 additional scenarios:

1. I want to Copy formulas with results to send to somebody (e.g. by email).
2. I've received an email with results of 1 above (formulas with results), and I want to Paste them with results ignored.

Function "pow2" doesn't work

In examples you use e.g.

pow2(6)

which isn't a valid function. pow(x,2) seems to work, though. Is "pow2" in examples a typo?

support operators +=, -=

Если можно, не помешала бы поддержка операторов инкремента и декремента

Строковые переменные с \n

При вводе строковых переменных с переносом строки, типа \n, не очень хорошо смотрится:

Было бы здорово сделать, чтобы выглядело как-то так:

Т.е. текст с переносами отображается табуированно, еще было бы классно, если бы новую команду на этой строке нельзя было написать.

problem with comments and strings literals

It seems that contents of the comments and string literals have some side effect.

The testcase for comments:

#  = r*tan(a) = tan(a)
tan(0)

The testcase for strings:

x= " = r*tan(a) = tan(a)"
tan(0)

Expected result: = 0
Actual result: // Error: Undefined symbol r
(in the both cases)

Perhaps there is need a proper parser instead of plain text processing.

Pi issue

there is something with the Pi const
