Types

type Command

type Command interface {
	RunCmdOut(cmd *exec.Cmd) ([]byte, error)
	RunCmd(cmd *exec.Cmd) error
}

Command is an interface used to run commands. All packages should use this interface instead of calling exec.Cmd directly.

var DefaultExecCommand Command = &Commander{}

DefaultExecCommand runs commands using exec.Cmd

type CommandWrapper added in v0.16.0

type CommandWrapper struct {
	// Executable is the base name of the command, like `gradle`
	Executable string

	// Wrapper is the optional base name of a command wrapper, like `gradlew`
	Wrapper string
}

CommandWrapper defines an association between an executable command (like `gradle`) and possible command wrappers (like `gradlew`). `CreateCommand` uses this definition to create a `Cmd` object. Maven and Gradle projects often provide a wrapper script to ensure a particular version of their builder is used.

func (CommandWrapper) CreateCommand added in v0.16.0

func (cw CommandWrapper) CreateCommand(ctx context.Context, workingDir string, args []string) *exec.Cmd

CreateCommand creates an `exec.Cmd` that is configured to call the executable (possibly using a wrapper in `workingDir`, when found) with the given arguments, with working directory set to `workingDir`.

type Commander

type Commander struct{}

Commander is the exec.Cmd implementation of the Command interface

func (*Commander) RunCmd added in v0.6.0

func (*Commander) RunCmd(cmd *exec.Cmd) error

RunCmd runs an exec.Command.

func (*Commander) RunCmdOut added in v0.6.0

func (*Commander) RunCmdOut(cmd *exec.Cmd) ([]byte, error)

RunCmdOut runs an exec.Command and returns the stdout and error.
