This guide assumes that you recently run brew upgrade postgresql and discovered to your dismay that you accidentally bumped from one major version to another: say 9.3.x to 9.4.x. Yes, that is a major version bump in PG land.

First let's check something.

brew info postgresql

The top of what gets printed as a result is the most important:

What is this?

This little script lets you easily define a few things you want from a web page (using CSS selectors), the crawl the site until you get them all.

It's based on the way Kimono works, but it's much simpler and has no limit to the number of results you can get. It also uses your auth tokens from the browser, so it's just as secure as your browser (which you should still be suspect of).

How do I use it?

Put that script into your browser terminal and run it. If you use Chrome, I highly recommend saving it as a snippet for easy reuse. To start scraping a site, create a Scraper instance with your desired options:

My notes for Dokku on Digital Ocean.

These may be a bit outdated: Since I originally wrote them, I've reinstalled on a newer Dokku and may not have updated every section below.

Commands

Install dokku-cli (gem install dokku-cli) for a more Heroku-like CLI experience (dokku config:set FOO=bar).

# List/run commands when not on Dokku server (assuming a "henroku" ~/.ssh/config alias)

ssh henroku dokku
