Functions

func Regex

func Regex(pattern string, invert bool) (func(string) bool, error)

Regex returns a line filter that matches lines against the given pattern. If invert is true, non-matching lines are kept instead.

func Truncate

func Truncate(lines []string, maxLines int) []string

Truncate applies smart truncation to a list of lines:

• Merges consecutive duplicate lines into "(repeated N times)" markers.
• If lines exceed maxLines, keeps head and tail with an omission notice in between.
• Tail-biased: 80% of the budget goes to the tail where errors typically appear.

maxLines <= 0 means no truncation.
