Is MicroPython supported?

[pfalcon]

This line: https://github.com/msiemens/tinydb/blob/master/tinydb/storages.py#L13 made me wonder, is https://github.com/micropython/micropython supported anyhow? (ujson is micropython's builtin json module, which offers subset of functionality).

The ujson I meant there is this one: https://github.com/esnme/ultrajson.

I think in principle TinyDB could run on MicroPython, but I assume that it would require a little bit of porting work as I'm currently using the re, os, contextlib, abc, os, warnings and sys Python modules.

@pfalcon Is there any interest in having this ported to MicroPython?

Thanks for clarification! MicroPython comes with a subset of stdlib, https://github.com/micropython/micropython-lib , and some of the modules you list already there (but likely subset of functionality is implemented), while some, like abc, aren't yet there. I just started writing my own simple file-based ORM, https://github.com/pfalcon/filedb , but then decided to do a quick search to make sure I don't duplicate effort, and was surprised by that line in tinydb. Well, I guess at this stage it makes more sense to continue working on filedb, as it's intended to run in the most minimal environments, but I'll keep in mind tinydb if something more advanced will be required. So, let me close this.

I'm searching around and started using TinyDB for another project. I think this would actually be useful in MicroPython. I'd be interested to see if you have the time to port this!

Hey @milkshakespoon, currently I don't have time to maintain a port. I've looked into this a little and MicroPython is incompatible with the current TinyDB codebase in a few regards (metaclasses not supported, collections.Mapping doesn't recognize dicts). So basically the only way to make it work would be to create a fork. If anyone wants to create one and maintain such a fork, I'll gladly link to it in the extensions list, but I'm afraid I can't do more.

Thanks for the response. Be awesome if someone does that! Unfortunately my coding skills are no where near good enough to create something like this.
