Overview

Package localexec provides constructs for uniform execution of local processes, specifically conversion from model.Cmd to exec.Cmd.

Types

type Env

type Env struct {
	// contains filtered or unexported fields
}

Common environment for local exec commands.

func DefaultEnv

func DefaultEnv(port model.WebPort, host model.WebHost) *Env

func EmptyEnv

func EmptyEnv() *Env

func (*Env) Add

func (e *Env) Add(k, v string)

func (*Env) ExecCmd

func (e *Env) ExecCmd(cmd model.Cmd, l logger.Logger) (*exec.Cmd, error)

ExecCmd creates a stdlib exec.Cmd instance suitable for execution by the local engine.

The resulting command will inherit the parent process (i.e. `tilt`) environment, then have command specific environment overrides applied, and finally, additional conditional environment to improve logging output.

NOTE: To avoid confusion with ExecCmdContext, this method accepts a logger instance directly rather than using logger.Get(ctx); the returned exec.Cmd from this function will NOT be associated with any context.
