"""Proof of concept of an adapter that will wrap a blocking IO library in
greenlets, so that it can be invoked by asyncio code and itself make calls out
to an asyncio database library.

hint:  any Python ORM or database abstraction tool written against the DBAPI
could in theory allow asyncio round trips to a pure async DB driver like
asyncpg.

The approach here seems too simple to be true and I did not expect it to
collapse down to something this minimal, so it is very possible I am totally

## Ever had to add something to your shell's config files (i.e. .bashrc)
## and open a new shell? Well, that may be fine, but you can achieve the

## lets check if any command `hello` exists
$ hello
bash: hello: command not found

// Package ravenerrors adds support for github.com/pkg/errors's stacktrace to github.com/getsentry/raven-go.

// https://github.com/getsentry/raven-go/issues/88#issuecomment-269002948

// It works as a replacement for github.com/getsentry/raven-go.CaptureError*.
// Stacktraces are extracted from the error if available and replace raven's default behavior.

Effective transpiling of ES6

After publishing my article on ECMAScript 6, some have reached out to ask how I exactly I make it all work.

I refrained from including these details on the original post because they're subject to immiment obsoletion. These tools are changing and evolving quickly, and some of these instructions are likely to become outdated in the coming months or even weeks.

The main tool

When evaluating the available transpilers, I decided to use 6to5, which has recently been renamed to Babel. I chose it based on:

bendc

// array utils
// =================================================================================================

const combine = (...arrays) => [].concat(...arrays);

const compact = arr => arr.filter(Boolean);

const contains = (() => Array.prototype.includes
  ? (arr, value) => arr.includes(value)
  : (arr, value) => arr.some(el => el === value)
