type Binding

type Binding struct {
	ViewName    string
	Handler     func(*gocui.Gui, *gocui.View) error
	Key         interface{} // FIXME: find out how to get `gocui.Key | rune`
	Modifier    gocui.Modifier
	Description string

Binding - a keybinding mapping a key and modifier to a handler. The keypress is only handled if the given view has focus, or handled globally if the view is ""

func (*Binding) GetDisplayStrings

func (b *Binding) GetDisplayStrings(isFocused bool) []string

GetDisplayStrings returns the display string of a file

func (*Binding) GetKey

func (b *Binding) GetKey() string

GetKey is a function.

type Gui

type Gui struct {
	Log           *logrus.Entry
	DockerCommand *commands.DockerCommand
	OSCommand     *commands.OSCommand
	SubProcess    *exec.Cmd
	State         guiState
	Config        *config.AppConfig
	Tr            *i18n.TranslationSet
	Errors        SentinelErrors

	T             *tasks.TaskManager
	ErrorChan     chan error
	CyclableViews []string
	// contains filtered or unexported fields

Gui wraps the gocui Gui object which handles rendering and events

func NewGui

func NewGui(log *logrus.Entry, dockerCommand *commands.DockerCommand, oSCommand *commands.OSCommand, tr *i18n.TranslationSet, config *config.AppConfig, errorChan chan error) (*Gui, error)

NewGui builds a new gui handler

func (*Gui) GenerateSentinelErrors

func (gui *Gui) GenerateSentinelErrors()

GenerateSentinelErrors makes the sentinel errors for the gui. We're defining it here because we can't do package-scoped errors with localization, and also because it seems like package-scoped variables are bad in general In the future it would be good to implement some of the recommendations of that article. For now, if we don't need an error to be a sentinel, we will just define it inline. This has implications for error messages that pop up everywhere in that we'll be duplicating the default values. We may need to look at having a default localisation bundle defined, and just using keys-only when localising things in the code.

func (*Gui) GetColor

func (gui *Gui) GetColor(keys []string) gocui.Attribute

GetColor bitwise OR's a list of attributes obtained via the given keys

func (*Gui) GetInitialKeybindings

func (gui *Gui) GetInitialKeybindings() []*Binding

GetInitialKeybindings is a function.

func (*Gui) GetOptionsPanelTextColor

func (gui *Gui) GetOptionsPanelTextColor() (gocui.Attribute, error)

GetOptionsPanelTextColor gets the color of the options panel text

func (*Gui) Run

func (gui *Gui) Run() error

Run setup the gui with keybindings and start the mainloop

func (*Gui) RunWithSubprocesses

func (gui *Gui) RunWithSubprocesses() error

RunWithSubprocesses loops, instantiating a new gocui.Gui with each iteration if the error returned from a run is a ErrSubProcess, it runs the subprocess otherwise it handles the error, possibly by quitting the application

func (*Gui) SetColorScheme

func (gui *Gui) SetColorScheme() error

SetColorScheme sets the color scheme for the app based on the user config

func (*Gui) WithWaitingStatus

func (gui *Gui) WithWaitingStatus(name string, f func() error) error

WithWaitingStatus wraps a function and shows a waiting status while the function is still executing

type SentinelErrors

type SentinelErrors struct {
	ErrSubProcess   error
	ErrNoContainers error
	ErrNoImages     error
	ErrNoVolumes    error

SentinelErrors are the errors that have special meaning and need to be checked by calling functions. The less of these, the better
