Crontab format parsing

Format follows that of the Vixie cron: https://man7.org/linux/man-pages/man5/crontab.5.html

including support for the following Date-Time matching: (month AND hour AND minute AND (day-of-month OR day-of-week))

Short 3-letter names for months and week days are supported, e.g. Jan, Wed.

Sunday's day of week number can be either 0 or 7.

Date-Time entities use java.time.ZonedDateTime for UTC timezone.

dt-future? clj

(dt-future? current-dt another-dt)

Return true if provided ZonedDateTime is in the future

dt-valid? clj

(dt-valid? dt days-of-month days-of-week)

Return true if a given ZonedDateTime satisfies day-of-month OR day-of-week constrains

get-current-dt clj

(get-current-dt)

Get current date time

get-dt clj

(get-dt year month day hour minute)

Return ZonedDateTime in UTC or nil for invalid Date-Time

get-dt-seq clj

(get-dt-seq s)

(get-dt-seq s year-from year-to)

Get a lazy sequence of future ZonedDateTime objects that satisfy crontab string.

When years range is ommited get a sequence for 1 year starting from the current one.

get-range clj

(get-range s range-type)

Parse a string into a sequence of numbers that represent a given Date-Time fragment's type, e.g. minutes, hours, days of month, etc.

list-regex clj

parse-cron clj

(parse-cron s)

Parse crontab string into map of ranges

parse-range clj

(parse-range s range-type)

Parse a string with the range of values with an optional step value

range-regex clj

range-values clj

seq-contains? clj

(seq-contains? coll e)

Return true if a sequence contains the element

skip-range clj

substitute-values clj

utc-tz clj
