Functions

func AtomicWrite added in v0.4.8 

func AtomicWrite(path string, data []byte, mode os.FileMode) error

AtomicWrite writes data to path atomically using a temp-file-then-rename pattern. This prevents corruption if the process crashes during the write.

func BuildConfirmDeleteCommand added in v0.4.8 

func BuildConfirmDeleteCommand(cfg ConfirmDeleteCommandConfig) *ffcli.Command

BuildConfirmDeleteCommand creates a standard delete command requiring --confirm.

func BuildPaginatedListCommand added in v0.4.8

BuildPaginatedListCommand creates a standard list command with --page-size, --paginate, --next, --output, and --pretty flags.

func ContextWithDryRun added in v0.4.2 

func ContextWithDryRun(ctx context.Context, dryRun bool) context.Context

ContextWithDryRun returns a context with the dry-run flag set.

func ContextWithTimeout 

func ContextWithTimeout(ctx context.Context, cfg *config.Config) (context.Context, context.CancelFunc)

func ContextWithUploadTimeout 

func ContextWithUploadTimeout(ctx context.Context, cfg *config.Config) (context.Context, context.CancelFunc)

func DefaultUsageFunc 

func DefaultUsageFunc(cmd *ffcli.Command) string

func DeprecatedAliasLeafCommand added in v0.4.8 

func DeprecatedAliasLeafCommand(original *ffcli.Command, oldName, newCommandPath string) *ffcli.Command

DeprecatedAliasLeafCommand creates a deprecated alias that wraps an existing command. When invoked, it prints a deprecation warning to stderr then runs the original command. The alias is hidden from parent help via the "DEPRECATED:" prefix in ShortHelp.

func DeriveUpdateMask added in v0.4.9 

func DeriveUpdateMask(raw []byte, mutableFields []string) (string, error)

DeriveUpdateMask extracts top-level keys from raw JSON and returns a sorted, comma-separated update mask containing only keys that appear in mutableFields.

We use an allowlist rather than a blocklist because the CLI unmarshals JSON into typed SDK structs before sending. The SDK drops unknown fields during unmarshal, so including an unknown key in the mask would create a mismatch (mask names a field the body doesn't contain) and cause a guaranteed 400.

func FormatUnknownCommand added in v0.4.2 

func FormatUnknownCommand(input string, commands []string) string

FormatUnknownCommand returns an error message with an optional suggestion.

func LoadJSONArg(value string, out interface{}) error

LoadJSONArg parses JSON from a literal string or @file path.

func LoadJSONArgRaw added in v0.4.9 

func LoadJSONArgRaw(value string) ([]byte, error)

LoadJSONArgRaw returns the raw JSON bytes from a literal string or @file path without unmarshaling. Use this when you need to inspect the JSON keys before parsing into a typed struct.

func WithSpinner added in v0.4.4 

func WithSpinner(label string, fn func() error) error

WithSpinner wraps fn with a braille spinner on stderr. If fn is nil, it returns nil immediately. If fn returns an error, WithSpinner returns it. If fn panics, the spinner stops and the panic is re-raised.

func WithSpinnerDelayed added in v0.4.4 

func WithSpinnerDelayed(label string, delay time.Duration, fn func() error) error

WithSpinnerDelayed wraps fn with a spinner that only appears after delay. Useful for operations that may complete quickly — no visual noise for fast calls.
