Overview ¶

Package exec provides useful wrappers around the standard "exec" library.

Index ¶

Types ¶

type Cmd ¶

type Cmd struct {
	*exec.Cmd
	// contains filtered or unexported fields
}

Cmd wraps exec.Cmd with a context to provide convenient execution of a command with nice checking of the context timeout in the form:

err := exec.Prog().WithTimeout(5*time.Second, myprog, myargs...).CombinedOutput(log, verbose)

func CommandContext ¶

func CommandContext(ctx context.Context, prog string, args ...string) *Cmd

CommandContext wraps exec.CommandContext to allow this package to be used as a drop-in replacement for the standard exec library.

func WithCancel ¶

func WithCancel(ctx context.Context, prog string, args ...string) (*Cmd, context.CancelFunc)

WithCancel creates a Cmd with a context that can be cancelled by calling the resulting Cancel() function.

func WithTimeout ¶

func WithTimeout(timeout time.Duration, prog string, args ...string) *Cmd

WithTimeout creates a Cmd with a context that times out after the specified duration.

func (*Cmd) CombinedOutput ¶

func (c *Cmd) CombinedOutput(scopedLog *slog.Logger, verbose bool) ([]byte, error)

CombinedOutput runs the command and returns its combined standard output and standard error. Unlike the standard library, if the context is exceeded, it will return an error indicating so.

Logs any errors that occur to the specified logger.

func (*Cmd) Output ¶

func (c *Cmd) Output(scopedLog *slog.Logger, verbose bool) ([]byte, error)

Output runs the command and returns only standard output, but not the standard error. Unlike the standard library, if the context is exceeded, it will return an error indicating so.

Logs any errors that occur to the specified logger.
