func Format ¶

func Format(w io.Writer, rows []Row, columns []string, format string) error

Format writes rows to w in the requested format. Supported formats: tsv, csv, json, table.

func InferColumns ¶

func InferColumns(rows []Row) []string

InferColumns collects all keys from rows, sorts them alphabetically, and puts sample_accession first if present.

func InferFormatFromPath ¶ added in v0.15.0

func InferFormatFromPath(path string) string

InferFormatFromPath returns "tsv", "csv", "json", or "" based on the file extension (after stripping a trailing .gz). Returns "" when the extension is missing or unrecognised so callers can fall through to their own defaults.

Exposed as a separate step (rather than baked into ResolveFormat) so each command can interleave it with config-driven defaults in the correct priority: --format flag > filename hint > configured default > TTY default.

func IsTerminal ¶

func IsTerminal() bool

func OpenWriter ¶ added in v0.15.0

func OpenWriter(path string) (io.Writer, func() error, error)

OpenWriter creates the file at path and returns a writer plus a close function. When path ends with .gz (case-insensitive) the returned writer is a gzip.Writer wrapping the file; the close function flushes the gzip stream and closes the underlying file. Callers must invoke close to avoid silently truncating the gzip trailer.

func ResolveFormat ¶

func ResolveFormat(format string) string
