Parsing a description ? (reverse parsing)
This tool is really great for parsing (or sanitizing) strings that have the osm opening_hours format, and getting them in a readable description. 💯
hoh.OHParser(" Mo-Fr 08:30-16:30", locale="fr").description()
// ['Du lundi au vendredi : 08:30 – 16:30.']
I was wondering if it was possible to leverage this tool (or another tool ?) to do the other way around ? 👇
hoh.parse_description("Du lundi au vendredi : 08:30 – 16:30", locale="fr")
// Mo-Fr 08:30-16:30
fyi my current implementation/workaround for this is with string replace 🙃
import re
oh_description = "Du lundi au vendredi : 08:30 – 16:30"
oh_description = re.sub("du", "", oh_description, flags=re.IGNORECASE)
oh_description = re.sub("lundi", "Mo", oh_description, flags=re.IGNORECASE)
...
Thanks anyway
Thank you!
Unfortunately, it would not be easily feasible with HOH by now, because the parsing and the rendering logic are very separated. It may be possible to use a Lark's Transformer to transform the tree (obtained from the parsing of the field) into a string, but all remains to be done, and it would make localisation quite difficult.
This way is feasible for simple fields, but not for more complex fields like Jan-Feb Sa[1] 08:30-16:30. The description (not even implemented) would be something like De janvier à février, le premier samedi du mois : 08:30 – 16:30.
You're right, it covers 80% of the use-cases, but fails on some specific stuff. I'm making it slowly grow, with tests, I'll see what to do when it becomes un-manageable :)
