Function NewSnippet

taskfile/snippet.go:58–77

NewSnippet creates a new [Snippet] from a byte slice and a line and column number. The line and column numbers should be 1-indexed. For example, the first character in the file would be 1:1 (line 1, column 1). The padding determines the number of lines to include before and after the chosen line.

(b []byte, opts ...SnippetOption)

// first character in the file would be 1:1 (line 1, column 1). The padding
// determines the number of lines to include before and after the chosen line.
func NewSnippet(b []byte, opts ...SnippetOption) *Snippet {
	snippet := &Snippet{}
	snippet.Options(opts...)

	// Syntax highlight the input and split it into lines
	buf := &bytes.Buffer{}
	if err := quick.Highlight(buf, string(b), "yaml", "terminal", "task"); err != nil {
		buf.Write(b)
	}
	linesRaw := strings.Split(string(b), "\n")
	linesHighlighted := strings.Split(buf.String(), "\n")

	// Work out the start and end lines of the snippet
	snippet.start = max(snippet.line-snippet.padding, 1)
	snippet.end = min(snippet.line+snippet.padding, len(linesRaw)-1)
	snippet.linesRaw = linesRaw[snippet.start-1 : snippet.end]
	snippet.linesHighlighted = linesHighlighted[snippet.start-1 : snippet.end]

	return snippet
}

// Options loops through the given [SnippetOption] functions and applies them
// to the [Snippet].
