sudo apt install libgtk-3-dev libxkbcommon-dev libwayland-dev libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libasound2-devIf macOS reports that par-term "is damaged and can't be opened", this is caused by the Gatekeeper quarantine attribute applied to unsigned binaries. Remove it with:
# For the release binary
xattr -cr target/release/par-term
# For the .app bundle
xattr -cr /Applications/par-term.appNote: The Homebrew cask install (
brew install --cask paulrobello/tap/par-term) handles this automatically.
par-term includes 49+ custom GLSL shaders for background effects and cursor animations. These need to be installed to your config directory.
Use the built-in CLI command to download and install all shaders from the latest release:
# Install shaders (with confirmation prompt)

# Install without prompts
par-term install-shaders -y
# Force overwrite existing shaders
par-term install-shaders --forceAlternatively, use the shell script installer:
# Download and run the installer
