@blinry Well. Several idea pop up. The currently focused Application is easy to find. With something like apt-file you can find the package, download the source package and show that. That won't be much fun.
If you were to limit it to python-Apps, showing the directory of the python-file seems easy. Then you will want an overlay fs to not destroy the installed App, but write changes to "disk" and rerun the application from there.
@snaums Yeah, I also thought this should work well with tools that do a "reverse lookup" from your binary to a software package!
You mean it won't be fun because you can't easily modify the source code and then use it immediately? That's probably right…
-
@TerryHancock Ohh, I didn't know it was still (kind of) maintained!
@blinry
Well, I have never actually tried it, but supposedly it's there.I do see the point in trying to port the "view source" feature to a more conventional DE. It seems unlikely that I could commit to using Sugar as a general purpose environment, but it would be cool for some of the ideas to get around.

@blinry
Is it possible to find out what shared library is responsible for some windows? I often wonder which project is actually behind the file browser or print dialog that I'm using and whether I can change it. My understanding is that these are usually delegated to an SO?@TerryHancock I've sometimes used `ldd` to show the linked libraries of a binary; but trying that on some examples the list seems to be either under- or overwhelming!

Remember the "One Laptop Per Child" project, that developed a low-cost computer for children in developing countries? I was always amazed by a certain feature: The "View Source" button.
When you pressed it, the source code for the currently running application would open. This was supposed to encourage tinkering with the software on your device!
I've been pondering what it would take to build that button on modern machines. Has anyone seen something like that?
(Prototype in next toot.)
@blinry my immediate thought was: step 1, write an accurate decompiler
-
Or have the entire system built around being interpreted like Python or C#. Maybe C# would even be a better option as it's JIT compiler is better in my eyes. And it integrates better with that XML based GUI definition language Microsoft had.
Edit: WPF XAML was it.
@agowa338 @blinry Wasn't C# simply a MS repackage of MS J++, the MS version of Java, because they were sued by Sun?
Years ago I used to peer inside Java "jars" on XP and Ubuntu.I found C# far better than VB.net, but both inferior to VB6 for quick GUIs on SQL or simulating keypad and LCD of a microcontroller and prototyping the code.
Then I went back to RF design and mostly abandoned programming apart from JAL on PIC18.
But view source is very niche. You only want the overhead on a Dev's PC. -

@blinry If you limit it to python, it could be fun. C/C++ code has to be compiled and that can take _a while_. Maybe it would work better on something like Gentoo. Or maybe you'd have a system, where in a special environment, everything is built from package-source once, then can be edited and recompiled in seconds.

And btw, there is basically 0 overhead from "view source" in C#, as the JIT will at runtime optimise the code and cache the compiled code until it is invalidated by you changing the source or something. In fact if you're writing powershell and the interpreter hits a loop the first few passes will be interpreted while it is in the background compiling it. And once it is done it'll on-the-fly switch over to the optimised compiled code.

(PowerShell may be an even better fit than C# for this usage...)

@blinry
Yeah, I've often wondered about that myself. I understand that you can install the Sugar DE on Linux, generally, and get that "view source" button. But it seems specifically designed to oppose multitasking, too.@TerryHancock @blinry The idea of Sugar (apps full screen one at a time) in a sense is like Android. Suited to small screen which OLPC had. It's only good for certain kinds of workflow or browsing. I upgraded from 1 x QHD to 1 x 4K and then 2 x 4K and use the screens like a large desk. I need reference materials.
I used virtual desktops on 1600 x 1200 XP over 20 years ago. I hate full screen applications except watching video / movies.
I have a portable 17" QHD screen extending 11" laptop. -

Good that the Powershell and dotNET teams already kinda split and opensourced themselves to avoid that

@blinry That would bring up a million of lines, linked to a dozen of larger libraries, that in the end work only in a properly configured virtual environment.
IMHO any fun and clear didactics has ended since almost thirty years. -

Oh and if you've done anything with REST-APIs or transforming file formats (aka mapping objects and such) then PowerShell is definitely killing it.
That's where it shines and even outperforms python in my eyes. Everything else it is kinda on-pair with python. Except you actually get working explicit typing (should you want to explicitly type something)
+ interop with unmanaged code is easier.

But I agree that this can get really hairy, depending on the application.

@agowa338 @raymaccarthy @blinry the open sourcing of dotNET was largely due to the Mono project, an independent reimplementation that started out as a way to run Silverlight (dotNET browser extensions) on Linux, and grew into a company that could compile C# for iOS, which Microsoft bought, and incrementally merged the Mono and dotNET

@ShadSterling @raymaccarthy @blinry
Well not just that. The community also for long asked for it and the development team also eyed with breaking out of the corporate Microsoft release cycle if I recall correctly.

@ShadSterling @agowa338 @blinry
Yes, J++ was. The C# (2004?) was very much a repackage of J++, but I tried both and stuck with VB6. I had used C++ from 1987.
Later I did some cross platform Java designed to maintain look & feel of what ever theme of XP or Vista used, whichever desktop + theme on Linux and for Mac, though I didn't personally test the Mac. Baffles me how badly Mozilla does; should know better. The Java app talked to a device driver for a PCMCIA based 4G card (not LTE or Wimax). -

@ShadSterling @agowa338 @blinry
Except I couldn't get Silverlight to run on any browser on Linux. The company I was advising did most of their work online using Silverlight.
Ironically MS was even then depreciating it! -

Because Silverlight was shit, even when compared with Flash and Java browser plugins. But all three got replaced by HTML5 (and when apple denied them on iOS)
