Pull in Calculus for a Native Calculator

There's Pantheon Calculator. Or there was, I don't remember what happened to it.

MBarvian wrote pantheon-calculator (https://launchpad.net/pantheon-calculator), but unfortunately is not an active contributor to the project any more.

Here's what it looked like: http://i.imgur.com/3KNbjsA.png

You are welcome to put a bounty on this, but it's not on track for Isis this late in the game.

It's some folks are already working on it. I may have to work on the icon to make it look good.

Sergio, before jumping on hacking, can you elaborate a bit more on your desired final app?

My main questions are the following:
    * Do you want to keep scientific/programmer mode or only basic mode.
    * How long does history has to go back in time. Only current session/last X sessions / last X queries / lifetime?
    * Any other special / non-traditional feature (clipboard support anyone?)

If you have any technical aspect that want to see covered please do add it.

1. WYSIWYG. Simple calculator app for the simple things.
2. History would only show the current sessions history
3. The entry box would be able to use the clipboard.
4. It should launch fast. Like instantly.
5. It should redo or undo anything you entered in the box.

In the mockups you presented it was a (kind of) borderless window. Do you still want it this way or can it be a more standar window. I would recommend the later, like the one I attached. Of course it can be tweaked to use the more modern head-bars (Is that how it is called?)

(BTW, I guess I can say I'm already working on it)

When I thought about this app I imagined it as a widget just like the one
+Dane Henson's agenda app. A pop up dialogue type app that serves one
simple purpose, fast, and sexy. It's not an app per say but rather a
widget. If you want to reference something I imagined look at this:

Are you guys wanting it to look more like http://i.imgur.com/3KNbjsA.png or more like the other elementary apps?

I started working on this as I have no seen any activity thus far. Let me know if someone else is working on it and I'll work on another thing.

@dubcanada
I'm working on it (There's a branch linked and I was assigned, no idea why you said there's no activity :P)

Oh my apologies, bountysource really doesn't show a lot of details ;)

There appears to be a whole bunch of people working on this.

I've come to a point where I need feedback from the developers on how to continue (functionality and UI is there), but I need to know if this is to become an official project to replace Gnome Calculator or a 3rd party app, among other things. If anyone could respond on this report (Or invite me to Slack since IRC seems dead, I don't mind it ;) ) would be of great help.

@Angel,
I'm sure the design team will add, but my comments are as follows:
* I can't resize the window
    * This would be a good option to allow a scientific mode, which has sin, cos, tan etc.
* I can't see what I typed, nor history
* Use a headerbar, even if it only has the title (like Pantheon Photos and Pantheon Terminal)
* The undo shouldn't be as is---replace with back/forward in history

Optional:
* Instant results that don't display errors until enter/= is pressed

Whoever wishes to take my code to continue this, feel free. It's done in C and GTK3. Very simple code base. Interface is modifiable with CSS. Still needs the calculator engine and history view.

https://github.com/lf94/luna-calc

I'm currently way too busy to fulfill this request.

Although there are a few projects for a native calculator app, I've started writing one, which is by now quite stable. Elementary Calculator (https://launchpad.net/elementarycalculator) is completely written with GTK3 and Vala. The UI is rather simple, but math functions and mathematical constants can be typed in. It has a history functionality for the current session and clipboard support.

Some screenshots are at http://imgur.com/a/tXb7R and with the dark theme at http://imgur.com/G9VF3n7.

Any comments?

Hey bud. Hit me up on Google plus.

No apparent activity from former assignee.

Would love to propose my own application calculus as well. I'm not sure what is the current state of adapting a native calculator application - if it's already decided, no problem, but I would love to hear some feedback :)

Marvin, since you want to try to work on this as well, I'd say it would be better to assign this to "nobody", to avoid any conflict.

I did not see your comment before, sorry. However, my application is done in terms of features I wanted to implement, so I wouldn't call it "try to work".

I see, that makes sense.

I've tested out Calculus and it seems to do its job. Marvin is hanging out with us in Slack these days working on the user accounts plug. He's been very responsive to bug reports. I like the way he's implemented the advanced mode. I think it'd be okay to lose the financial and programming modes. If you really need a crazy calculator, it's not like you can't just install one.

I want to add that - if needed - calculus could be renamed into something more suiting to the pantheon/elementary app suite like pantheon-calc.

It is not possible to fire bug on pantheon-calculator yet, but i think order of buttons is wrong. They should be in this order: / x - + also "plusminus" button should be there. See original gnome-calculator.

Bugs for pantheon-calculator are now open, please consider to re-report your bug. Also, I do not know what you mean by the "plusminus" button, to be honest :/

I think he means a button to change to negative digits (like -200 + 300 = 100, for example). You can do that by clicking the - button before the number, there's no reason to add another button just for that.

not a bug, just a sugestion: classic gnome-calculator could be launched from any multimedia keyboard that had a special key for calculator (for example, my Asus K53SD uses Fn + NumpadEnter). Could this system be applied to pantheon-calculator?
