Types

type CensoredWriter

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

CensoredWriter is a writer wrapping the provided io.Writer with logic to censor certain values

func NewCensoredWriter

func NewCensoredWriter(writer io.Writer) *CensoredWriter

NewCensoredWriter returns a new CensoredWriter

func (*CensoredWriter) SetSensitiveValues

func (cw *CensoredWriter) SetSensitiveValues(vals []string)

SetSensitiveValues sets values needing masking for an CensoredWriter

func (*CensoredWriter) Write

func (cw *CensoredWriter) Write(b []byte) (int, error)

Write implements io.Writer's Write method, performing necessary auditing while doing so

type CommandBuilder

type CommandBuilder func(name string, arg ...string) *exec.Cmd

func NewTestCommand

func NewTestCommand(c *Context) CommandBuilder

type Context

type Context struct {
	Debug        bool
	DebugPlugins bool

	FileSystem         aferox.Aferox
	In                 io.Reader
	Out                io.Writer
	Err                io.Writer
	NewCommand         CommandBuilder
	PlugInDebugContext *PluginDebugContext
	// contains filtered or unexported fields
}

func New

func New() *Context

New creates a new context in the specified directory.

func (*Context) Chdir

func (c *Context) Chdir(dir string)

Chdir changes the current working directory to the named directory.

func (*Context) Clearenv

func (c *Context) Clearenv()

Clearenv deletes all environment variables.

func (*Context) Command

func (c *Context) Command(name string, arg ...string) *exec.Cmd

Command creates a new exec.Cmd using the context's current directory.

func (*Context) CopyDirectory

func (c *Context) CopyDirectory(srcDir, destDir string, includeBaseDir bool) error

func (*Context) CopyFile

func (c *Context) CopyFile(src, dest string) error

func (*Context) Environ

func (c *Context) Environ() []string

Environ returns a copy of strings representing the environment, in the form "key=value".

func (*Context) EnvironMap

func (c *Context) EnvironMap() map[string]string

EnvironMap returns a map of the current environment variables.

func (*Context) ExpandEnv

func (c *Context) ExpandEnv(s string) string

ExpandEnv replaces ${var} or $var in the string according to the values of the current environment variables. References to undefined variables are replaced by the empty string.

func (*Context) Getenv

func (c *Context) Getenv(key string) string

Getenv retrieves the value of the environment variable named by the key. It returns the value, which will be empty if the variable is not present. To distinguish between an empty value and an unset value, use LookupEnv.

func (*Context) Getwd

func (c *Context) Getwd() string

Getwd returns a rooted path name corresponding to the current directory.

func (*Context) IsVerbose

func (c *Context) IsVerbose() bool

func (*Context) LookPath

func (c *Context) LookPath(file string) (string, bool)

This is a simplified exec.LookPath that checks if command is accessible given a PATH environment variable.

func (*Context) LookupEnv

func (c *Context) LookupEnv(key string) (string, bool)

LookupEnv retrieves the value of the environment variable named by the key. If the variable is present in the environment the value (which may be empty) is returned and the boolean is true. Otherwise the returned value will be empty and the boolean will be false.

func (*Context) SetSensitiveValues

func (c *Context) SetSensitiveValues(vals []string)

SetSensitiveValues sets the sensitive values needing masking on output/err streams

func (*Context) SetVerbose

func (c *Context) SetVerbose(value bool)

func (*Context) Setenv

func (c *Context) Setenv(key string, value string)

Setenv sets the value of the environment variable named by the key. It returns an error, if any.

func (*Context) Unsetenv

func (c *Context) Unsetenv(key string)

Unsetenv unsets a single environment variable.

func (*Context) WriteMixinOutputToFile

func (c *Context) WriteMixinOutputToFile(filename string, bytes []byte) error

WriteMixinOutputToFile writes the provided bytes (representing a mixin output) to a file named by the provided filename in Porter's mixin outputs directory

type PluginDebugContext

	RunPlugInInDebugger    string
	PlugInWorkingDirectory string
	DebuggerPort           string
}

func NewPluginDebugContext

type TestContext

type TestContext struct {
	*Context

	T *testing.T
	// contains filtered or unexported fields
}

func NewTestContext

func NewTestContext(t *testing.T) *TestContext

NewTestContext initializes a configuration suitable for testing, with the output buffered, and an in-memory file system, using the specified environment variables.
