* Parse a subset of the OSM opening_hours format into FarmaClic's internal
|
|
* shape: { mon: ["09:00", "21:00"], ..., sun: null }.
|
|
*
|
|
* Supports the patterns commonly seen on amenity=pharmacy nodes:
|
|
* "24/7"
|
|
* "Mo-Fr 09:00-21:00"
|
|
* "Mo-Fr 09:00-21:00; Sa 09:00-14:00; Su closed"
|
|
* "Mo,We,Fr 09:00-14:00"
|
|
* "Mo-Fr 09:00-13:30,16:30-20:00" (split shifts: opens first, closes last)
|
|
*
|
|
* Public-holiday rules (PH/SH) and weeknumber/date filters are ignored.
|
|
* Returns null if no usable rule was found.
|
|
*
|
|
* @param {string} input
|
|
* @returns {{mon: string[]|null, tue: string[]|null, wed: string[]|null, thu: string[]|null, fri: string[]|null, sat: string[]|null, sun: string[]|null}|null}
