Overview ¶
Package datepattern translates GoBan's `datepattern:` rule field into a Go time-layout string. Operators write either a named preset (sshd, iso8601, rfc3339, etc.) for ergonomics or a raw Go layout literal for anything custom. Resolve does the dispatch and is intentionally tiny — the bulk of date handling lives in the rule processor.
Recognised presets cover the log formats GoBan's bundled rule library targets. New presets are cheap to add but they should reflect real-world log shapes, not theoretical ones — every preset is a maintenance commitment.

Functions ¶
func Presets ¶
func Presets() []string
Presets returns the recognised preset names, sorted for documentation use. Returned slice is a copy; callers may mutate it freely.
func Resolve ¶
Resolve returns the Go time layout corresponding to spec. spec may be:
- a recognised preset name (case-insensitive) — returns the canonical layout
- a raw Go layout literal containing the reference year "2006" — returned as-is
Anything else returns an error. The "contains 2006" heuristic is how Go's own time package identifies a layout, so accepting it here keeps the ergonomic story consistent: if it parses with time.Parse it'll work as a datepattern.
