/**
Main worker routine. The routine implements custom regex language to
simplify date transformations. The given regex and substitution strings
can contain magic words that specify what date format the routine should
accept and to what date format the routine should convert the date to.
Aside from magic strings, ordinary regular expressions and substitution
strings are accepted. Leading and trailing slashes are not needed for the
regex.
The magic string can be either capturing or non-capturing. The capturing
magic strings make their output available for later processing. Most of
the capturing magic strings can be used in the output with equivalent
meaning.
Internally, the routine maintains information about several dates, so the
regex can contain more than one magic string specifying day, month or year.
The first date will be assigned the first occurrences of magic strings from
each group, the second date will be assigned the second occurrences and so
on. For example, if the regex is '@MM @DD @YYYY, @Month @ZM @Day', the
first date will be assigned @MM as months, @DD as days and @YYYY as years.
The second date will be assigned @Month as months and @Day as days. The
third date will be assigned @ZM as months.
If used in the replacement string, all magic strings in the format @XX will
output the data of the first date. To access the subsequent dates, magic
strings in the format @XX2, @XX3, and so on must be used. @XX1 is provided
as alias to @XX for convenience.
AVAILABLE REGEX MAGIC STRINGS
=============================
Note: The capturing magic strings start with an uppercase letter whereas
the equivalent non-capturing magic strings start with a lowercase
letter.
Days:
@SD Matches a day in numeric format without leading zero (1..31).
@ZD Matches a day in numeric format with leading zero (01..31).
@DD Matches a day in numeric format with optional leading zero (@SD or @ZD)
@Day A day in numeric format with optional leading zero, with optional st,
nd or th suffix. Equivalent to @DD@th?
@sd, @zd, ... : noncapturing equivalents
@th Matches st, nd, rd or th
Months:
@SM A month in numeric format without leading zero (1,2..12).
@ZM A month in numeric format with leading zero (01,02..12).
@MM A month in numeric format with optional leading zero (@SM or @ZM)
@FullMonth Matches full name of a month (January, February)
@Mon Matches short name of a month (Jan, Feb, ..). Also optionally
matches dot (Jan., Feb., ..) and 'Sept', 'Sept.'.
@Month Matches full or short name of a month (@FullMonth or @Mon)
@sm, @zm, ... : noncapturing equivalents
Years:
@YYYY Matches a 4-digit year
@YY Matches a 2-digit year. 50-99 are interpreted as 1950..1999,
0-49 are interpreted as 2000-2049.
@YYNN Matches 4 or 2-digit year (@YYYY or @YY).
@Year Matches 1 to 4 digit year
@yyyy, @yy, ... : noncapturing equivalents
@@ Matches literal @
AVAILABLE REPLACEMENT STRING MAGIC STRINGS
==========================================
Days:
@SD: Outputs a day in numeric format without leading zero (1-31).
@ZD: Outputs a day in numeric format with leading zero (01-31).
@DD: Equivalent to @ZD
@Day: Equivalent to @SD
@LDay: Outputs the matched day string without any transformations
@SDn, @ZDn, ..., where n is integer
Outputs the day of the nth date in the specified format.
Months:
@SM Outputs a month in numeric format without leading zero (1-12)
@ZM Outputs a month in numeric format with leading zero (01-12)
@MM Equivalent to @ZM
@FullMonth Outputs a full name of a month (January, February)
@Mon Outputs a short name of a month (Jan, Feb)
@Month Equivalent to @FullMonth
@LMonth Outputs the matched month string without any transformations
@SMn, @ZMn, ..., where n is integer
Outputs the month of the nth date in the specified format.
Years:
@YYYY Outputs 4-digit year. Valid only if the year was not captured
by @Year
@YY Outputs 2-digit year. Outputs the last two digits of a year.
Valid only if the year was not captured by @Year
@YYNN Equivalent to @YYYY
@Year Outputs 1 to 4 digit number identifying a year. Equivalent to
@YYYY if the year is between 1000 and 9999
@LYear Outputs the matched year string without any transformations.
@YYYYn, @YYn, ..., where n is integer
Outputs the year of the nth date in the specified format.
@@ Outputs literal @
All magic strings in the replacement string, which refer to data which was
not defined, will be replaced witht '@ERROR@'
An optional function defining whether to make replacement in particular
case can be provided. The function is supplied a number of parameters, each
of which is an object defining the nth date as parsed by the routine. Each
object contains numeric values of days, months and years as 'd', 'm' and 'y'
properties respectively. Each value can be -1 if a magic string for that
date value was not specified in the regex, or an error occurs. The function
should return true if the replacement should be done, false otherwise.
