feat(cli): give failures distinguishable exit codes - #304
Merged
Conversation
Every error exited 1, so a script could not tell an unknown type from an unreachable cluster. Add an error that carries an exit code, and map usage failures (invalid flag value, bad arguments, unrecognised command) to a distinct code. Cobra reports an unrecognised subcommand only for a non-runnable command and before validating args, so the root becomes runnable to keep that case inside the contract. Silencing Cobra's own reporting also silences its usage hint, so main prints both the hint and the lowercase "error:" prefix the rest of the CLI's diagnostics use.

Making the root runnable to catch an unrecognised subcommand had two costs that review caught. The root now reached PersistentPreRunE, so a bad ~/.karta/config.yaml turned bare karta into an error instead of the help that would explain it, while karta --help still worked because it short-circuits earlier. The root only prints help, so it no longer loads config at all. Setting Args on the root also bypassed the Cobra helper that appends "Did you mean this?", losing typo recovery for anyone reaching for a command that moved. The block is rendered explicitly, including the minimum-distance default Cobra applies inside that helper. Also unify the reporting an invalid input gets: both stub commands share one argument validator rather than one wrapping and one not, an out-of-range output value is a usage error whether it came from a flag, the environment or a config file, and the usage hint names the command that rejected the input instead of always the root. Drop ExitNotFound, which nothing here returns; it lands with the command that needs it. Tests read config from the environment, so they now run against an isolated HOME. That also fixes a pre-existing dependence on the developer machine in TestOutputValidation. Signed-off-by: Roee Gil <roee.gil@run.ai>

- Around line 23-26: Preserve the explicit configEnvVar setup in
TestBareRootIgnoresConfig: avoid having exitCodeOf clear it before execution by
invoking NewRootCommand().Execute() directly there, or extend exitCodeOf to
accept and retain the required environment value. Keep the test’s invalid config
path active so it verifies the bare root command ignores that configuration.

method receivers and constructor references, including usageError, while
preserving the existing behavior and fields.

TestBareRootIgnoresConfig set KARTA_CONFIG to a deliberately broken file, then called a helper that cleared the same variable before running, so the test ran without a config at all and passed with the fix it guards reverted. Split the helper into environment isolation and execution so the test can isolate first and then set the config path it needs. Also correct three comments: the reason for silencing Cobra sat above SilenceUsage rather than the SilenceErrors it explains, the suggestion-distance note claimed a zero value matches nothing when a prefix typo still matches, and two doc comments led with a clause restating the signature.

#305, #306 and #309 all landed as squashes, so this branch's copies of their commits conflicted with the merged result. Take main's side throughout, and carry over only what this branch owns: the get command, the clusterAccess seam its tests use, and registering get in place of the workload tree. Three things had to be reconciled rather than chosen: ExitNotFound returns. #304's review dropped it because nothing referenced it; get is the caller #205 specified, for an unknown type and for no definitions at all. The renderer moved. get now calls RenderWorkloads, the workload-specific entry point, rather than the Render this branch predates. The view no longer carries a component breakdown or a GPU total, so the table assertions, the JSON contract assertion and the command's own help text drop their claims to both. nested_test.go goes for the same reason; main deleted it, and the merge kept it as a file only this branch had.

What does this PR do?
First of a five-PR stack that adds
karta get. This one is independent of the command itself: it gives failures distinguishable exit codes.Every error exited 1, so a script could not tell an unknown workload type from an unreachable cluster. This adds an error type carrying an exit code and maps usage failures to a distinct one.
The numbers are not a contract; the property callers rely on is that the conditions differ.
Two things worth a reviewer's attention:
karta wrkloadinside the contract rather than exiting 1.mainnow prints both the hint and the lowercaseerror:prefix the rest of the CLI's diagnostics use, replacing Cobra'sError:.This changes user-visible output, so it is worth a release note even though it is the smallest PR in the stack.
