length

type Unit ¶

type Unit int

Unit represents units of measurement for the length of a string.

The most commonly used Unit in protocompile is TermWidth, which approximates columns in a terminal emulator. This takes into account the Unicode width of runes, and tabstops. The rune A is one column wide, the rune 貓 is two columns wide, and the multi-rune emoji presentation sequence 🐈‍⬛ is also two columns wide.

Other units of length can be used to cope with the needs of other rendering contexts, such as the Language Server Protocol.

const (
	Bytes     Unit = iota // The length in UTF-8 code units (bytes).
	UTF16                 // The length in UTF-16 code units (uint16s).
	Runes                 // The length in UTF-32 code units (runes).
	TermWidth             // The length in approximate terminal columns.
)
