Functions

func ParseState

func ParseState(str string) (string, map[rune][2]int64)

ParseState parses an editor state description.

An editor state description describes the contents of the buffer and the editor's marks. Runes that are not between { and } represent the buffer contents. Each rune between { and } represent the beginning (first occurrence) or end (second occurrence) of a mark region with the name of the rune.

As a special case, the empty string, "", is equal to "{..}".

For example:

"{mm}abc{.}xyz{.n}123{n}αβξ"

Is a buffer with the contents:

"abcxyz123αβξ"

The mark m is the empty string at the beginning of the buffer. The mark . contains the text "xyz". The mark n contains the text "123".

func StateEquals

func StateEquals(text string, marks map[rune][2]int64, descr string) bool

StateEquals returns whether the state (text plus marks) equals the described state.

func StateString

func StateString(text string, marks map[rune][2]int64) string

StateString returns the state string description of the text and marks. The returned string is in the format of ParseState. The returned string is normalized so that multiple marks within { and } are lexicographically ordered.
