once run
Run a declared target
Synopsis#
plaintext
once run [OPTIONS] [TARGET] [ARG]
Description#
Resolves the target id against the workspace graph and executes its run capability through the action cache. Use --remote to ask a compute provider to execute the command.
Arguments#
| Argument | Required | Description |
|---|---|---|
<TARGET> | no | Target id, e.g. examples/hello/hello or ./hello |
<ARG> | no | Target-kind-specific arguments supplied to the generic run capability |
Options#
| Flag | Value | Default | Description |
|---|---|---|---|
--sandbox | <SANDBOX> | off | Local filesystem sandbox policy for command actions |
--config | <KEY=VALUE> | Override the workspace build configuration. See once build --config | |
--visible | (flag) | false | Ask graph target kinds to open a visible runtime interface when supported |
--runtime-rpc | (flag) | false | Serve a local JSON-RPC runtime control socket for this run |
--runtime-rpc-socket | <RUNTIME_RPC_SOCKET> | Runtime RPC socket path. Defaults to .once/runtime/<session>/control.sock | |
--remote | (flag) | false | Run the target's action on a compute provider |
--compute | <PROVIDER> | Compute provider used with --remote. Defaults to the configured execution provider | |
-C, --directory | <DIR> | Project root. Defaults to the current directory; the cache lives under <project>/.once/. Mirrors make -C | |
--format | <FORMAT> | human | Output format for Once's structured data (cache stats, run/exec trailers). Defaults to a human-readable rendering; pass json or toon to get machine-parseable output for scripting and for agent consumers |
-v, --verbose | (flag) | 0 | Increase log verbosity. Repeat for more (-v: info, -vv: debug, -vvv: trace). Overridden by RUST_LOG |
-q, --quiet | (flag) | false | Suppress human-mode success and progress trailers. Errors and the structured envelope of --format json/toon still print. Mirrors the -q flag of common build tools |
--list | (flag) | false | Print the command surface at the current command depth |
--memory-limit | <SIZE> | Maximum memory scheduling budget for local actions. Defaults to two thirds of the memory visible to the host or container |
