I tried your repo as well. I cloned it and did `nimble build`, but it failed with this: [http://ix.io/2nAa/text](http://ix.io/2nAa/text)
It looks like the `psutil` dependency needs to be updated for a backward incompatible change that happened in nim 1.0.0. Now we have `isDigit` taking only `char` arg, not `string`. I'll open a PR on `psutil` to fix this.
