reformat 'date' into new format specified by format_param if pattern_idx (the current format of 'date') can be | |||
reformatted. Does the grunt work for reformat_dates(). | |||
]] | The table re_formats maps pattern_idx (current format) and format_param (desired format) to a table that holds: | ||
format string used by string.format() | |||
identifier letters ('d', 'm', 'y', 'd2', 'm2', 'y2') that serve as indexes into a table t{} that holds captures | |||
from mw.ustring.match() for the various date parts specified by patterns[pattern_idx][1] | |||
Items in patterns{} have the general form: | |||
[' | ['ymd'] = {'^(%d%d%d%d)%-(%d%d)%-(%d%d)$', 'y', 'm', 'd'}, where: | ||
['ymd'] is pattern_idx | |||
patterns['ymd'][1] is the match pattern with captures for mw.ustring.match() | |||
patterns['ymd'][2] is an indicator letter identifying the content of the first capture | |||
patterns['ymd'][3] ... the second capture etc. | |||
when a pattern matches a date, the captures are loaded into table t{} in capture order using the idemtifier | |||
characters as indexes into t{} For the above, a ymd date is in t{} as: | |||
t.y = first capture (year), t.m = second capture (month), t.d = third capture (day) | |||
To reformat, this function is called with the pattern_idx that matches the current format of the date and with | |||
format_param set to the desired format. This function loads table t{} as described and then calls string.format() | |||
with the format string specified by re_format[pattern_idx][format_param][1] using values taken from t{} according | |||
to the capture identifier letters specified by patterns[pattern_idx][format_param][n] where n is 2.. | |||

This function allows automatic date formatting. In ~/Configuration, the article source is searched for one of | |||
the {{use xxx dates}} templates. If found, xxx becomes the global date format as xxx-all. If |cs1-dates= in | |||
{{use xxx dates}} has legitimate value then that value determines how cs1|2 dates will be rendered. Legitimate | |||
values for |cs1-dates= are: | |||
l - all dates are rendered with long month names | |||

ly - publication dates use long month names; access-/archive-dates rendered in ymd format | |||
s - all dates are rendered with abbreviated (short) month names | |||
sy - publication dates use abbreviated month names; access-/archive-dates rendered in ymd format | |||
y - all dates are rendered in ymd format | |||

value supplied by |cs1-dates so one of: xxx-l, xxx-ls, xxx-ly, xxx-s, xxx-sy, xxx-y, or simply xxx (|cs1-dates= | |||
empty, omitted, or invalid) where xxx shall be either of dmy or mdy. | |||
dates are extracted from date_parameters_list, reformatted (if appropriate), and then written back into the | |||
list in the new format. Dates in date_parameters_list are presumed here to be valid (no errors). This function | |||
returns true when a date has been reformatted, false else. Actual reformatting is done by reformatter(). | |||
