This is the log from the development window console:

notificationsAlerts.ts:40 Command 'Nand2Tetris: Run Code' resulted in an error (command 'nand2tetris.run' not found)

See attached image. It doesn't like the multiple 'out' values with that last one being a subset. Perfectly valid syntax. Whether or not the HDL is correct or not... well... still working on that ;)

Hi there, thanks for this plugin.

It would be great if there was a command to open the VM emulator tool.

I'm working on the simplified ALU in project 2 (ALU-nostat), however, I've found an odd behavior.

I've created a file called ALU-nostat.hdl, with the contents attached.

However, what happens is that, unless I perform modifications to ALU.hdl, when running the code, the out file is not updated.

To reproduce:

1. Save the attached file as ALU-nostat.hdl in the project/02 directory
2. Run the code; the output file will have 0000000000000000 in the output pin
3. Convert the (only) part to be Or16(a=false, b=true, out=out);
4. Run the code; the output file won't change
5. Open ALU.hdl and save it with any modification
6. Run ALU-nostat.hdl
7. The output file will now have 1111111111111111 in the output pin

Hi leafmaple,

thanks for your nand2tetris extension. It works really nice. Have you heared of codium?
The thing is, that microsoft develops vs-code in the following way:
They have a free open source project licensed under MIT license called "Code - OSS"
From this code base they build vs-code after adding proprietary extension and telemetry (data sharing).
Now for users concerned with free open source software that want the "original" MIT code editor without proprietary blobs and telemetry addons there is a repo, which uses the same code basis to build a real free alternative called "codium".

To use extensions with codium they offer an alternative marketplace
https://open-vsx.org

I would really apreciate, if you could publish your extension also on this platform, so users who are concerned about free software in the sence of freedom could enjoy using it.

For an explanation on the difference of vs-code and codium see:
https://www.roboleary.net/tools/2022/05/31/vscode-vscodium-which-should-i-use.html

Alternatively can you explain, where I can find the "*.vsix" file of your extension so I could download it and install it in the command line with "codium --install-extension xxx.vsix"

Best regards
Micha

When executing Run Code (for HDL files), the Output panel doesn't autoscroll. This is quite annoying, since it's typical to run the code multiple times in order to debug it.
