Vide

A basic wgpu gui renderer intended to be used with Neovide based on ideas from Vello and Zed's rendering approaches but with a focus on simplicity.

Some key goals and principles we are trying to follow with this effort:

1. Use wgpu as the graphics library for maximum portability.
2. Define a scene format which can fluently be defined in rust code, and can be serialized to disk for easy rendering and logging.
3. Render the entire scene layer by layer. Within a layer individual components are drawn in declaration order by kind reducing the need for offscreen buffers.
4. Where possible, features of the renderer should be regression tested to ensure that changes do not change the quality of the rendering unless explicitly intended.

Dependencies

The tests require the nerd fonts to be installed. Run the following:

Windows

scoop bucket add extras
scoop bucket add nerd-fonts 
scoop install Monaspace-NF FiraCode-NF ProFont-NF CascadiaCode-NF Noto-NF

Mac

brew install font-monaspace font-fira-code-nerd-font font-profont-nerd-font font-caskaydia-cove-nerd-font font-monaspace-nerd-font font-noto-nerd-font

Linux

FONT_DIR="${HOME}/.local/share/fonts"
mkdir -p "$FONT_DIR"

for font in ${{ env.FONTS }}; do
  ZIP_FILE="${font}${EXTENSION}"
  if [[ "$font" == "Monaspace" ]]; then
    DOWNLOAD_URL="https://github.com/githubnext/monaspace/releases/download/v1.101/monaspace-v1.101.zip"
  else
    DOWNLOAD_URL="https://github.com/ryanoasis/nerd-fonts/releases/download/${VERSION}/${ZIP_FILE}"
  fi
  echo "Downloading and installing '$font'..."
  wget --quiet "$DOWNLOAD_URL" -O "$ZIP_FILE"
  unzip -oq "$ZIP_FILE" -d "$FONT_DIR"
  rm "$ZIP_FILE"
  echo "'$font' installed successfully."
done
