Constants

const HistoryLimit = 1000

HistoryLimit is the maximum number of entries saved in the scrollback history.

Functions

func Asset

func Asset(name string) ([]byte, error)

Asset loads and returns the asset for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetDir

func AssetDir(name string) ([]string, error)

AssetDir returns the file names below a certain directory embedded in the file by go-bindata. For example if you run go-bindata on data/... and data contains the following hierarchy:

data/
  foo.txt
  img/
    a.png
    b.png

then AssetDir("data") would return []string{"foo.txt", "img"} AssetDir("data/img") would return []string{"a.png", "b.png"} AssetDir("foo.txt") and AssetDir("notexist") would return an error AssetDir("") will return []string{"data"}.

func AssetInfo

func AssetInfo(name string) (os.FileInfo, error)

AssetInfo loads and returns the asset info for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetNames

func AssetNames() []string

AssetNames returns the names of the assets.

func ContainsVal

func ContainsVal(ps *env.ProgramState, b []env.Object, val env.Object) bool

func Dict2Context

func Dict2Context(ps *env.ProgramState, s1 env.Dict) env.RyeCtx

func DiffBlocks

func DiffBlocks(ps *env.ProgramState, a env.Block, b env.Block) []env.Object

func DiffLists

func DiffLists(ps *env.ProgramState, a env.List, b env.List) []any

func DiffStrings

func DiffStrings(a string, b string) string

func FormatCsv

func FormatCsv(val env.Object, e env.Idxs) string

func FormatJson

func FormatJson(val env.Object, e env.Idxs) string

func FormatSsv

func FormatSsv(val env.Object, e env.Idxs) string

func IndexOfAt

func IndexOfAt(s, sep string, n int) int

func IndexOfSlice

func IndexOfSlice(ps *env.ProgramState, slice []env.Object, value env.Object) int

func IntersectBlocks

func IntersectBlocks(ps *env.ProgramState, a env.Block, b env.Block) []env.Object

func IntersectLists

func IntersectLists(ps *env.ProgramState, a env.List, b env.List) []any

func IntersectStrings

func IntersectStrings(a string, b string) string

func IsTruthy

func IsTruthy(o env.Object) bool

func MustAsset

func MustAsset(name string) []byte

MustAsset is like Asset but panics when Asset would return an error. It simplifies safe initialization of global variables.

func ReadSecure

func ReadSecure(filename string, password string) string

func RemoveDuplicate

func RemoveDuplicate(ps *env.ProgramState, slice []env.Object) []env.Object

func RestoreAsset

func RestoreAsset(dir, name string) error

RestoreAsset restores an asset under the given directory

func RestoreAssets

func RestoreAssets(dir, name string) error

RestoreAssets restores an asset under the given directory recursively

func SaveSecure

func SaveSecure(textToEncrypt string, filename string, password string)

func SplitEveryList

func SplitEveryList(s []env.Object, chunkSize int) [][]env.Object

func SplitEveryString

func SplitEveryString(s string, chunkSize int) []string

func SplitMulti

func SplitMulti(s string, seps string) []string

func StringToFieldsWithQuoted

func StringToFieldsWithQuoted(str string, sepa string, quote string) env.Block

func TermBold

func TermBold(s string) string

func TermError

func TermError(s string) string

func TruncateString

func TruncateString(s string, maxLen int) string

func UnionOfBlocks

func UnionOfBlocks(ps *env.ProgramState, a env.Block, b env.Block) []env.Object

func UnionOfLists

func UnionOfLists(ps *env.ProgramState, a env.List, b env.List) []any

func VerySimpleRyeHighlight

func VerySimpleRyeHighlight(c string) string

Types

type KeyEvent

type KeyEvent struct {
	Key   string
	Code  int
	Ctrl  bool
	Alt   bool
	Shift bool
}

type MLState

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

State represents an open terminal

func NewMicroLiner

func NewMicroLiner(ch chan KeyEvent, sb func(msg string), el func(line string) string) *MLState

NewLiner initializes a new *State, and sets the terminal into raw mode. To restore the terminal to its previous state, call State.Close().

func (*MLState) AppendHistory

func (s *MLState) AppendHistory(item string)

AppendHistory appends an entry to the scrollback history. AppendHistory should be called iff Prompt returns a valid command.

func (*MLState) ClearHistory

func (s *MLState) ClearHistory()

ClearHistory clears the scrollback history.

func (*MLState) MicroPrompt

func (s *MLState) MicroPrompt(prompt string, text string, pos int) (string, error)

signals end-of-file by pressing Ctrl-D.
