Types

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 https://dave.cheney.net/2017/06/11/go-without-package-scoped-variables 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
