logopen() does this internally, but you might want to manually craft the "regex": for a .fmt descriptor. In such cases, you can use regex() or update() to combine the log.fmt with definitions from the global fmt database.

regex()

Takes a .fmt json/dict, and generates the regex with named capture groups from it.

::: logfmt1.regex

---

rx2re()

::: logfmt1.rx2re

---

update()

Updates the regex: property in a .fmt dict. Also injects any used fields: or alias: lists. (For now this is basically just a wrapper of the regex() builder.)

::: logfmt1.update
