Usage

Run

gurk

On the first run, it will open a QR code in your favorite image viewer, such that you can link the client as a new device. This will also create a configuration file at the default config location. For the configuration directives, see src/config.rs.

Note: The binary cannot be published on crates.io, because it depends on several official Signal libraries that are not available on crates.io.

Configuration

Command-line options

-c, --config <PATH>     Path to config file
    --data-dir <PATH>   Path to data directory

Environment variables

Variable	Description
GURK_CONFIG	Path to config file (same as --config)
GURK_DATA_DIR	Path to data directory (same as --data-dir)
XDG_CONFIG_HOME	Base directory for config files (works on all platforms)
XDG_DATA_HOME	Base directory for data files (works on all platforms)

Config file locations

If no config path is specified, gurk searches these locations in order:

1. $XDG_CONFIG_HOME/gurk/gurk.toml (if XDG_CONFIG_HOME is set)
2. $XDG_CONFIG_HOME/gurk.toml (if XDG_CONFIG_HOME is set)
3. Platform config directory (e.g. ~/Library/Application Support on macOS, ~/.config on Linux)
4. $HOME/.gurk.toml

Data directory

The data directory (for messages, Signal database, attachments) is determined by:

1. --data-dir CLI option or GURK_DATA_DIR env var
2. data_dir setting in config file
3. $XDG_DATA_HOME/gurk (if XDG_DATA_HOME is set)
4. Platform data directory (e.g. ~/Library/Application Support/gurk on macOS)

Custom keybindings

The default keybindings can be overwritten at startup by configuring keybindings in gurk.toml using the format keybindings.<mode>.<keycombination> = "<command>". Valid commands are anywhere, normal, message_selected, channel_modal, multiline, and help. Valid key combination specifiers are e.g. left, alt-j, ctrl-f, backspace, pagedown. The default keybindings can be disabled by setting default_keybindings = false. An empty command removes an existing binding if it exists in the given mode. Configuration troubleshooted by running RUST_LOG=gurk=trace,presage=trace,libsignal=trace gurk --verbose and examining the resulting gurk.log.
