logicrs's Issues

feature: Auto-node Layout

It would be cool to be able to automatically arrange nodes (gates) with a button

Add clock for synchronous circuits

We need to implement the clock that can be operated on the chosen frequency. This will be useful in many other modules.

Common selection features missing

• drag multiple selected blocks as one
• hold shift to add to selection
• hold ctrl to toggle selection status

-> this interferes with Ctrl+LMB (pan), which should be reassigned to just Middle mouse button without ctrl (is also more consistent as MMB is now used for both pan and zoom. note that currentöy ctrl+mmb is not working as you said it would, only ctrl+lmb)

feature: "Duplicate" option as shortcut for copy/paste when rightclicking blocks

MacOS support

In theory, MacOS should already be supported as both GTK and Rust support it. However, I cannot validate this because I don't have access to an apple computer.

Loops not working

Suggestion - Publishing it on Flathub

It would be nice if this app would be published on Flathub.

Module can be used in its own definition [FUTURE BUG]

Issue

A module being used in its own definition could lead to infinite recursion.
Note that this is potentially not true for all configurations.
I has to be checked recursively for modules using modules that use the current module
(aka recursion where the loop is larger than 1 element)

Deleting modules doesn't work reliably

RIGHT Click -> Delete on (connected) modules often has no effect. Deleting the gate again after moving it usually works.

feature: move multiple blocks at once

When pasting, the pasted items should be all selected

Pasting three blocks, all of them should be selected and the previous blocks should all be sdeselected

[feat] 3bitAND and 3bitOR gates to be present by default

I feel like 3 bit and and 3 bit or gates should be put by default in the app since they are used in few complex logic gates.
I don't know rust so I can't code it atm

Windows installer

Add an installer .exe (or .msi (?)) file to the releases that installs logicrs and some example projects automatically on Windows targets.

Currently, logicrs is distributed via portable .zip files

Input/output delete dialog not greyed out

Issue

"delete" option on rightclick should be greyed out or removed completely since input/output nodes aren't deletable.
Deleteion works as expected on normal nodes.

Example of greyed out option:

Feature: increase range of node connection

When dragging a wire between two nodes, it would be nice if you didn't have to drop the wire exactly on the connection point. There should be a radius within which you can drop the wire where it still connects.

Feature request: Tick rate slider, "advance one step" button when tick rate slider is on 0

"System default" theme not working

defaults to light mode even though my pc is in dark mode.
Needs to be verified, i installed a new window manager so that might interfere although thats unlikely

Double click on disabled undo/redo button toggles fullscreen

Issue

Doble click on disabled history button (when reaching end of history) toggles fullscreen as it would when just clicking on the title bar next to it, instead of just doing nothing, as it should. This is an issue when rapildly undoing, but it might not qualify as an issue.

Potential fix:

Still capturing the click event even though the button is disabled

File extension for windows

Issue

"Save file" window does not have "json" (or later the actual extension) in the "save as type" dialog on windows. "Open" dialog doesnt have the preferred extension box at all.

Reproduction

Open save file dialog

Potential Fix

---

Theme not being saved upon close/open

theme resets every time i open

Add unit tests for all builtin modules

Each builtin module (defined in src/simulator/builtin) should have its own unit test validating that it behaves according to its truth table.

Logicrs icon in taskbar/corner of window is defaulted to GTK logo

[no code] Want to add CODE_OF_CONDUCT.md file

CODE_OF_CONDUCT.md file is missing in logicrs repo.

Add new (interesting) examples

Add new example projects to the examples/ directory, like subtractors, multipliers, gates, etc.

This does not require writing any code

No module name length limit/weird ui behavior on long names

#Issue
There is no limit for module name lengths, resulting in weird scrolling when secting in the sidebar, where selecting any module toggles between scrolling to the right and to the left (making first or last part of long nave visible).

Names of modules in editor arent truncated, resulting in gigant modules

This might also cause issues on exporting due to file name length limits.

Microsoft Windows has a MAX_PATH limit of ~256 characters.
Note that this limit is for the whole file path, not just the file name so the name should be kept at something considerably shorter

Theme button does not show which one is selected

current one should be marked as selected or otherwise highlighted

Zoom + Drag offset not accounted for

Issue

Position is not adjusted for the offset created by zooming

Reproduction

holding down LMB on a component/wire and scroll to zoom (see images)

Potential Fix

Centering zoom on mouse pointer would make the issue disappear since the offset would be 0. Additionally, it is a more natural way to zoom

pressing ctrl and then switching windows [alt+tab] keeps ctrl selected when returning until pressed and released again

probably not much that can be done about it, maybe you can jus deselect all keys on WindowUnfocus event?
