once cache action get [OPTIONS] [ACTION]Description
Identify the action either by passing its digest directly, or by declaring its inputs with --input; the same declaration must be used on put to write under the same key.
Arguments
| Argument | Required | Description |
|---|---|---|
<ACTION> | no | Pre-computed action digest |
Options
| Flag | Value | Default | Description |
|---|---|---|---|
--input | <SPEC> | Input spec (see cache hash for the grammar). Repeatable; inputs are hashed in order and combined into the action digest | |
--if-success | (flag) | false | Exit 0 only when there is a hit AND the recorded exit code is 0. On miss or on a cached failure, exit non-zero |
-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 |
