Overview

Package snippet implements the specification for the LSP snippet format.

Snippets are "tab stop" templates returned as an optional attribute of LSP completion candidates. As the user presses tab, they cycle through a series of tab stops defined in the snippet. Each tab stop can optionally have placeholder text, which can be pre-selected by editors. For a full description of syntax and features, see "Snippet Syntax" at https://microsoft.github.io/language-server-protocol/specifications/specification-3-14/#textDocument_completion.

A typical snippet looks like "foo(${1:i int}, ${2:s string})".

func (*Builder) Clone

func (b *Builder) Clone() *Builder

Clone returns a copy of b.

func (*Builder) PrependText

func (b *Builder) PrependText(s string)

func (*Builder) String

func (b *Builder) String() string

String returns the built snippet string.

func (*Builder) Write

func (b *Builder) Write(data []byte) (int, error)

func (*Builder) WriteChoice

func (b *Builder) WriteChoice(choices []string)

WriteChoice writes a tab stop and list of text choices to the Builder. The user's editor will prompt the user to choose one of the choices.

func (*Builder) WriteFinalTabstop

func (b *Builder) WriteFinalTabstop()

WriteFinalTabstop marks where cursor ends up after the user has cycled through all the normal tab stops. It defaults to the character after the snippet.

func (*Builder) WritePlaceholder

func (b *Builder) WritePlaceholder(fn func(*Builder))
