I happened to have hazelnut.io until recently. Unfortunately I let it expire since the original project I was planning on using there was much more complex than anticipated. So now it's parked by someone else [1], otherwise it was yours

Shame I didn't post this earlier, that TLD would have been awesome.

How is this different than psutil?

this is `cat /proc/meminfo | grep Swap`

The API of this lib is probably surprising for the typical use-cases because a MemInfo object only represents a path and not a reading/snapshot of the file (each subsequent call to get() re-reads the meminfo file).

https://github.com/mrsmn/hazelnut/blob/master/hazelnut/core....

So usage like:

   snap_pre = MemInfo()
   # Do stuff here
   snap_post = MemInfo()
   snap_pre.get('Mem')
   snap_post.get('Mem')
   snap_post.get('Mem')
   # All three would likely give different values.

I would suggest caching the read on instantiation or making them top level functions instead of using a class or MemInfoPath()?

You can cross reference of /proc/meminfo output into the kernel source code here:
