Functions

func ANSIWriter 

func ANSIWriter() *ansi

ANSIWriter returns an io.Writer which translates any ANSI escape codes written to it into tview color tags. Other escape codes don't have an effect and are simply removed. The translated text is written to the provided writer.

func InitScreenAndRun added in v0.1.0 

func InitScreenAndRun(m *testing.M, screen *tcell.Screen)

unfortunately, tcell misbehaves if we try to make a new Screen for every test this function is intended for use from a `TestMain`, so that we can have a global Screen across all tests in the package

func IsEmpty added in v0.4.1 

func IsEmpty(l Component) bool

A ConcatLayout element can be either fixed or dynamic. Fixed components are all given a chance at the full canvas. If they ask for too much in sum, things will break. Dynamic components get equal shares of whatever is left after the fixed components get theirs. NB: There is currently a bit of a murky line between ConcatLayout and FlexLayout.

type Tokenizer added in v0.2.0 

type Tokenizer struct {
	// contains filtered or unexported fields

A tokenizer that breaks a string up by spaces.

Ideally, we'd use the table-based algorithm defined in: http://www.unicode.org/reports/tr14/ like this package does: https://godoc.org/github.com/gorilla/i18n/linebreak but I didn't find a good implementation of that algorithm in Go (the one above is half-implemented and doesn't work for the most basic things).

This is a half-assed implementation that should have a similar interface to a "real" implementation.
