second-date.parse.builder
Utility functions for programatically building a DateTimeFormatter. Easier to understand than chaining a hundred
Java calls and trying to keep the structure straight.
The basic idea here is you pass a number of sections to formatter to build a DateTimeFormatter — see
second-date.parse for examples. Most of these sections are simple wrappers around corresponding
DateTimeFormatterBuilder -- see
https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatterBuilder.html for documenation.
TODO - this is a prime library candidate.
Utility functions for programatically building a `DateTimeFormatter`. Easier to understand than chaining a hundred Java calls and trying to keep the structure straight. The basic idea here is you pass a number of `sections` to `formatter` to build a `DateTimeFormatter` — see `second-date.parse` for examples. Most of these sections are simple wrappers around corresponding `DateTimeFormatterBuilder` -- see https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatterBuilder.html for documenation. TODO - this is a prime library candidate.
