lavagna's Introduction

lavagna

It's a blackboard, not a lasagna.

Lavagna is a collaborative blackboard, perfect for creating simple sketches during online meetings. It has an (optional) minimal toolbar which can be hidden to avoid distractions from your drawings. You can control colors and line width using the keyboard or the toolbar.

It's just you, your peers, and your creativity.

Keyboard bindings

Button	Action	Note
C	Color	Change the chalk color
M	Grow	Grow chalk size 2x
N	Shrink	Shrink chalk size 2x
X	Clear	Clear the whole blackboard
U	Toolbar	Toggle toolbar visibility

Installation

Archives of precompiled binaries for lavagna are available for Windows, macOS and Linux.

Install from source

If you're a Rust programmer, lavagna can be installed with cargo.

Note that the minimum supported version of Rust for lavagna is 1.76, although lavagna may work with older versions.

To install from sources:

git clone https://github.com/alepez/lavagna.git
cd lavagna
cargo install --path lavagna --locked

Install from crates.io

Currently, installing from crates.io is not available. See this issue.

Instant collaboration

lavagna uses WebRtc for instant collaboration. So you can use it for online meetings. You don't even need to install anything, because lavagna is available as a web-app too.

You need a signaling server like matchbox_server installed somewhere. See this post by Johan Helsing

Don't worry, for quick testing you can borrow my signaling server:

lavagna --collab-url ws://lavagna.alepez.dev:3536/demo

Change demo to your preferred name or a unique id. If you do the same on different device, anything you draw will be visible on the other side (and vice versa).

Desktop app development

lavagna works on many operating systems:

Linux (x86)
Linux (ARM)
macOS (x86)
Windows

You just need to have a Rust toolchain installed. Run this from the project directory:

cargo run

To print help information, just use:

cargo run -- --help

Web app development

This script builds all the assets needed for a web application. You'll find them on www directory, so you can use any http server able to serve static files.

./tools/build-web
cd www
python -m http.server 8000

See also docker/lavagna-webapp/Dockerfile as an example of how to publish the web-app.

lavagna's Issues

Current version of Lavagna is incompatible with Firefox

Describe the bug
When building Lavagna on Windows with the build-web script, the resulting site works on Chrome but not Firefox.

When loading on Firefox, the following errors appear in the console:

See "Additional context" for what I believe to be the root cause and fix (which worked on my computer).

To Reproduce
Steps to reproduce the behavior:

Check out the main branch
With git bash, run tools/build-web (On my computer, it needed to be modified with export rustflags="--cfg=web_sys_unstable_apis" to be able to build)
Run python -m http.server in the www directory (defaults to port 8000)
Load http://localhost:8000 on Firefox
Open the console and see the error.

Expected behavior
I expect Lavagna to open on Firefox it does on Chrome.

Desktop

OS: Windows
Browser: Firefox
Version: 121.0

Additional context
My wasm-bindgen version is 0.2.89.

I believe the root cause is that the web build is defaulting to WebGPU and not WebGL2. I was able to fix this by adding the webgl2 feature to bevy. Due to my unfamiliarity with Bevy, this fix was not easy to find, as the console did not mention WebGPU, and there were no mentions of WebGPU or WebGL2 in the codebase, making me originally doubt that this was the root case.

Adding the webgl2 feature had the added benefit of removing the requirement to add export rustflags="--cfg=web_sys_unstable_apis" to the build script.

Adjustable pen size

Make the pen size adjustable

from 1 to 32 pixels

M key button grow

Spikes when large line is used

Describe the bug
When the line width is large, little cursor movements generate spikes.

To Reproduce

Select maximum line width
keep pressing, do small movements

Expected behavior

A roundish shape should be drawn.

Instead, these spikes appear on the screen:

Incorrect asset path

When launching lavagna from CLI, it prints the following error:

ERROR bevy_asset::server: path not found: /usr/bin/assets/fonts/FiraMono-Medium.ttf

And the lack of font causes the toolbar to be blank.

Steps to reproduce

On ArchLinux, install lavagna from AUR
Launch lavagna
Observe the error in logs

Expected behavior

No error and the toolbar displays correctly.

I took a brief look at the code. It appears that the intention is to use bevy_embedded_assets to embed the fonts. I assume there is some misconfiguration.

Enable collaboration in Android

CLI app can enter the url as a command line parameter, while Android needs an alternative method.

When collaborating, cursor position is shared

Describe the bug
When collaborating, cursor position is shared: while user1 is pressing and user2 move the cursor over the canvas without touching, the pencil draw a line jumping from user1 position to user2 position.

To Reproduce
Steps to reproduce the behavior:

Open a collaborative lavagna in two different computers.
Start drawing and keep pressing on computer A
Just move the mouse in computer B
A line is drawn from position in computer A to position in computer B

Expected behavior

Nothing should be drawn when mouse is just moving without pressing in computer B, if A is drawing.

Demo website

Once upon a time we had lavagna.devand.dev server. I've shut down devand.dev, so I need another place for lavagna.

This was the documentation when the server was at lavagna.devand.dev

## Online demo

An online demo is available: [demo](https://lavagna.devand.dev)

It supports passing options as url parameters:

- collaboration
  url: https://lavagna.devand.dev/?collab-url=ws://lavagna.alepez.dev:3536/demo
- debug
  pane: https://lavagna.devand.dev/?collab-url=ws://lavagna.alepez.dev:3536/demo&dbg=true
-

ui: https://lavagna.devand.dev/?collab-url=ws://lavagna.alepez.dev:3536/demo&dbg=true&ui=true

Possible solutions:

GitHub pages for webapp + my own server for matchbox
GitHub pages for webapp + johanhelsing server for matchbox, like the one used by https://helsing.studio/box_game/ (I should ask)
Both webapp and matchbox on my own server

cargo install fails – could not find asset folder

Describe the bug
When performing cargo install lavagna, the compilation process fails. The bevy_embedded_assets can't find the assets folder.

Full output, directly after Compiling <dependency> v<version>:

The following warnings were emitted during compilation:

warning: [email protected]: Could not find asset folder, please specify its path with $BEVY_ASSET_PATH

error: failed to run custom build command for `bevy_embedded_assets v0.7.0`

Caused by:
  process didn't exit successfully: `/tmp/cargo-installklO25G/release/build/bevy_embedded_assets-36be3b4b8a9ca65c/build-script-build` (exit status: 101)

error: failed to compile `lavagna v2.1.7`, intermediate artifacts can be found at `/tmp/cargo-installklO25G`.
To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.

To Reproduce
Steps to reproduce the behavior:

Assure that you have cargo installed.
cargo install lavagna

Expected behavior
The log throws no errors and lavagna is installed at ~/.cargo/bin/lavagna.

Desktop (please complete the following information):

OS: Arch Linux
Version:
- rustup 1.26.0
- cargo 1.75.0-nightly

Side Note
In my project, I have the same issue. I uploaded it to crates.io but can't cargo install, due to the same error messages, although cargo package --list lists my assets folder.

Thank you in advance.

In-progress strokes are invisible when the camera is panned too far from the origin.

Describe the bug
In-progress strokes are invisible when the camera is panned too far from the origin. I believe the root-cause is related to frustum culling (See additional context).

To Reproduce
Steps to reproduce the behavior:

Zoom out
Zoom in elsewhere
Draw a stroke
See that the in-progress stroke is invisible until you release the mouse (or you've passed POINTS_CHUNK_THRESHOLD)

Expected behavior
The in-progress stroke is visible no matter where the camera is.

Additional context
I believe the root cause is bevyengine/bevy#4294. I was able to resolve this locally by editing make_chalk to add the NoFrustumCulling component to in-progress strokes.

Demo site down?
