Configuration

Every field in config.toml — settings and the monitor-manager layout that ShareClick uses to route your cursor between machines.

ShareClick reads a single config.toml. The settings window writes it for you, but you can edit it by hand. Create one with:

shareclick init-config

Top-level fields

Field	Meaning
name	This machine’s name. Must match one entry under [[machines]].
psk	Shared passphrase (≥ 8 chars). Identical on both machines. Authenticates + encrypts.
port	Network port (default 24800). Same on both.
auto_edge_switch	Hand control over when the cursor hits a bordered edge.
server_host	(Client only) the server’s IP, e.g. 192.168.1.20. Omit to auto-discover.

The psk is stored in plaintext in the config file. Pick a long, random passphrase, keep it identical on both machines, and never commit it. Protect the file with normal OS file permissions. See Security.

The monitor manager ([[machines]])

The [[machines]] array is the layout: each machine lists which peer sits on each edge (left / right / top / bottom). When auto_edge_switch is on, pushing the cursor into a bordered edge hands control to that neighbour.

[[machines]]
name = "mac"
right = "windows"          # windows is to the right of mac

[[machines]]
name = "windows"
left  = "mac"              # mac is to the left of windows

Screen sizes are auto-detected — this machine’s from the OS, and the other’s is reported automatically the first time it connects. Add screen = [w, h] under a machine only to override a wrong auto-detection.

Full example

Server

name = "mac"
psk  = "pick-a-long-secret"
port = 24800
auto_edge_switch = true

[[machines]]
name = "mac"
right = "windows"

[[machines]]
name = "windows"
left  = "mac"

name = "windows"
psk  = "pick-a-long-secret"
port = 24800
auto_edge_switch = true
server_host = "192.168.1.20"

[[machines]]
name = "mac"
right = "windows"

[[machines]]
name = "windows"
left  = "mac"

New config fields ship with #[serde(default)], so older config files keep loading after an upgrade. See the Releasing versioning policy.
