I've tried two samples, and I get no output:

solve2( 3 * x + y = 10 ;  2 * y + x  = 12 ; x ; y)
solve(a * x = 2 ; x)

None of those work. Am I doing something wrong or is this an actual bug?

Currently it's nasc, should be com.github.parnold-x.nasc.

When you type "solve(y+x=x/y", it'll crash the program immediately upon the typing the second y. Hope this helps.

I think it makes sense for NaSC to appear in the Science & Engineering section of AppCenter (and app menus) since it has a lot of use in science and engineering.

specifically <url type="bugtracker">https://github.com/parnold-x/nasc/issues</url>

When I open "Sharing via PasteBin", the dialog gives me no option by default.
It still allows the user to share the sheet without choosing expiry time and it gives back an empty window no link as a result.

Linux Manjaro - probably current app (no version is visible :( )
Example on left: (1 -0.02839446 /0.0284405) * 100
On right I see: 0.16188182

When I select on right side 0.16188182 and click copy it doesn't work (no copy)

Ok it is working when pure numbers are in input for such input it doesn't work:

#Hello World

(1 -0.02839446 /0.0284405) * 100 

If NaSC does not get a chance to close properly, e.g. system shutdown or crash, data gets lost.

Trigonometry functions do not work for angles different from zero.

It's best practice to include a <developer_name> in your appdata so we can properly credit you as the developer in AppCenter.

When i try to sum or subtract a percentage it just sum the zero dotted value to the first number.
As an example, if i do
100 - 30% = 99.7
instead of 70 as i was expecting
I'm using the 0.4.3 version.

I think it would be appropriate for nasc to appear under the Education category :)

When enabling the dark theme for every window using the elementary os tweak tool, the window border and background colors are overwritten, but the text color does not change, making it really hard to read. It would be awesome if it could somehow display an alternate color palette when using the dark theme globally.

Could it be possible to export to LaTeX?? Or maybe markdown image?
Thanks!

It would be nice to have a way to change the window opacity, that way I can overlay NaSC on top of my math papers

I made an attempt to provide a Flatpak package for your excellent NaSC. The build files are available at https://github.com/phw/nasc-flatpak

The build is currently fine, but it requires some patching (see the patch files in the repository):

1. Most important is patching of the app ID from com.github.parnold-x.nasc.gschema.xml to com.github.parnoldx.nasc.gschema.xml (without the dash). Flatpak doesn't allow the dash here, I filed an issue to ask on clarification on flatpak/flatpak-builder#37 .
2. lib dir path for qcalculate, would be solved by #57
3. Hard coded template path for qcalculate

The last two issues should be solved upstream here. For the first issue we maybe need to keep the patch.

One remaining issue that it fails to update the exchange rates on startup. Not sure why, I experimented with --share=network without luck.

I would like to submit this to flathub.org if we get the issues above sorted out. If somebody wants to test this locally you can build a local package by cloning the repository and run:

flatpak-builder --repo=repo com.github.parnoldx.nasc com.github.parnoldx.nasc.json --force-clean
flatpak build-bundle repo nasc.flatpak com.github.parnoldx.nasc
flatpak install nasc.flatpak

Then run it via the desktop icon or from command line:

flatpak run com.github.parnoldx.nasc

Add the Ability to convert from Hexadecimal to Binary to Decimal.
Currently NaSC is neither able to represent binary nor able to do math with it.

After start right pane has contents of what is behind, but it is not transparency, as during window move contents moves too. When result is changed, it is also not cleared.

gentoo, gtk+-3.22.11, cairo-1.14.8, vala-0.34.8

upd.: in ResultView.vala alpha is set to 0, must be 100
upd2: they are double values

File in question
https://github.com/parnold-x/nasc/blob/nasc/data/com.github.parnold-x.nasc.appdata.xml

Should be:
It's an app
Instead of:
Its an app

As "It's" is being used as a contraction of "it is"

Is this intentional or a bug?

It's not enforced yet, but in the future it'll be necessary to avoid namespace collisions

When I try sharing the math sheet through PasteBin, the resulting link opens the page which tells me "This page has been removed"


After I open this URL: https://pastebin.com/XZw5GUX

It behaves the same with different expiration times, "private" option and different names.

I tried using euler but the value of that variable is .5772 etc. Using e on its own returns nothing.

I want to calculate ln e, but it returns nothing. I also tried log e. It should return 1

Whenver you input a "function" it should automatically input the parentesis.
For example
If I type solve and typed space it should automatically insert parentesis ()

Because it'd be swell :)

When doing calculations, it would be very useful for the user to be able to add comments at the end of a line in the input area, to be able to keep track of what exactly he or she is calculating. The comments would be ignored by the calculator.

I can imagine this could be implemented with a symbol such as " or // that's not otherwise used. So it might look like

1156         // daily requirement
7 * 166        // number of days
line1 * line2    // total requirement!

I can add a new sheet with the Ctrl+N shortcut, but so far I don't see any visible way to access my previous sheets. The source code suggest there is a footer toolbar. Is this not yet implemented or is it a bug that I can't see it?
