Functions

func ExtractProgram

func ExtractProgram(raw string) string

ExtractProgram strips markdown fences and surrounding whitespace from model output.

func Run

func Run(awkBin string, fieldSep string, programPath string, stdin io.Reader, stdout io.Writer) error

Run executes awk with optional -F and a program file, streaming stdin to stdout.

func RunCSV

func RunCSV(awkBin string, csvDelimiter string, programPath string, stdin io.Reader, stdout io.Writer) error

RunCSV parses stdin as CSV and executes awk over normalized rows. It preserves quoted fields (including commas) by parsing first, then joining fields using an internal separator that awk receives via -F.

func Validate

func Validate(awkBin, programPath string) error

Validate runs awk -f against an empty stdin to catch syntax errors.

func WriteTemp

func WriteTemp(dir, program string) (string, error)

WriteTemp writes program to a temp file and returns its path.
