Microsoft Open-Sources Windows Calculator (betanews.com) 292

Posted by msmash from the marching-forward dept.
Microsoft said today it has made the source code for its Windows calculator available on GitHub. The company said it hopes to work with contributors to improve the user experience of Windows calculator. In a statement, Dave Grochocki and Howard Wolosky of Microsoft said: Today, we're excited to announce that we are open sourcing Windows Calculator on GitHub under the MIT License. This includes the source code, build system, unit tests, and product roadmap. Our goal is to build an even better user experience in partnership with the community. We are encouraging your fresh perspectives and increased participation to help define the future of Calculator. As developers, if you would like to know how different parts of the Calculator app work, easily integrate Calculator logic or UI into your own applications, or contribute directly to something that ships in Windows, now you can. Calculator will continue to go through all usual testing, compliance, security, quality processes, and Insider flighting, just as we do for our other applications.

    Sure. This isn't 100% PR.

    If there was ever any piece of software that is done and needs no more work, it was this one.

    • Indeed, I can't think of what I'd add. The benefit of a widget like calc.exe is that it starts *immediately*. It's a sub second start for sub-minute work. If I need anything more than what it provides, I'm firing up a spread sheet or some advanced number-crunching program that takes longer to start, but I'm OK with that because I'm going to be spending 15 minutes or more with it.

      What baffles me is why they don't fix Notepad. I mean there are a TON of good other really basic text editors out there (Win32pad is my favorite for a direct replacement), but really all they'd need to do to make that program significantly more useful would be to make it handle Unix line-breaks correctly, and have some indicator (eg, a status bar) of cursor position within the file.

      There are other things that would be nice, but those fixes would literally take any decent programmer less than an hour to implement. I'm half convinced they lost the source code to the Notepad back in the Win95 days . . .

      • Funny you say that. My 1 and only idea as to how to "improve" calculator.exe was to have it running in some state, in the background, and any time one starts typing (while not focused on any windows) numbers followed by mathematical signs, it should spit out the answer on the screen. Basically keep the program part that does the calculations, but don't improve the interface, remove the interface.

        • Most of us probably are not calculating numbers anywhere near as often as you. I'd find this distracting.

          • It could also get really annoying really fast if you just wanted to type an equation without the answer. Just think how aggravating it would be if you just wanted to type 2 + 2 and it automatically appended = 4 every time. You would then have to compensate by deleting the extra text just like you have to fight with autocomplete on smartphones.

        • Yeah bc is wonky; it has a bug / feature where it only uses the precision of the input. Dividing by 1.0 forces full precision. These seem to be the general heuristics:

          Addition: precision = min( lhs, rhs )
          Multiplication: precision = lhs + rhs - 1, but doesn't seem consistent
          Division: precision specified by scale

          Given this input ...

          bc -l

    While I agree with the general consensus that releasing the source to calculator is underwhelming, I'm wondering if there is more to the plan here.

    Maybe Microsoft has a long term goal of making more apps open-source, to help with the support workload or to develop more Microsoft developers and maybe find some UI designers with fresh approaches.

      I'm sure there is, because otherwise, why bother? I think this is just them dipping their toes into the water, to see how interacting with the open source community on an app that ships with Windows will work. So they want to start with something innocuous.

      Unfortunately, they've chosen an app that's so innocuous that they may be disappointed in the response. They may take from the experience that it's not worth open sourcing stuff, because no one contributes anyway.

This could be a benefit to students who have to share calculators in school and can't afford one for home use (or those times you just don't have one on you). Having it shipped and supported right inside Windows would be a great benefit for students.
  • In Windows 7, Start > Run > Calc and calculator loads instantly and you can start using it. That's when the calculator appeared to be written using Windows Forms. When they switched to Modern UI or WPF in Windows 10, when you open it, Start > Run > Calc. wait...wait...wait... and then it's open. Nearly every application that they switched from 7 to 10 in this way has a loading lag that wasn't there before.

      The old windows7 calculator was a win32 app. That started up almost instantly. (you say it's Windows Forms, but I think that's wrong. Windows Forms is a .NET layer on top of the win32 "user32.dll" API for displaying dialogs/buttons/windows. I think calculator used the win32 API directly, as do many C/C++ win32 apps. There are two different C++ layers on top of user32.dll which calc might have used... I'm not sure.)

    The Win10 calculator has an awful UI. It's huge -- much bigger than it needs to be. As others here have noted, it also starts slowly, since it's a Windows Store app and not a normal Win32 program. As others here have also noted, it may not work at all if your network's firewall blocks Windows Store access. (Or you remove the Windows Store from Windows.)
