Creating a VM

• vagrant init -- Initialize Vagrant with a Vagrantfile and ./.vagrant directory, using no specified base image. Before you can do vagrant up, you'll need to specify a base image in the Vagrantfile.
• vagrant init <boxpath> -- Initialize Vagrant with a specific box. To find a box, go to the public Vagrant box catalog. When you find one you like, just replace it's name with boxpath. For example, vagrant init ubuntu/trusty64.

Starting a VM

• vagrant up -- starts vagrant environment (also provisions only on the FIRST vagrant up)
• vagrant resume -- resume a suspended machine (vagrant up works just fine for this as well)
• vagrant provision -- forces reprovisioning of the vagrant machine
• vagrant reload -- restarts vagrant machine, loads new Vagrantfile configuration
• vagrant reload --provision -- restart the virtual machine and force provisioning

Common Options

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar <file name> File to save response cookies to.

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Sphinx Setup for autodoc

Sphinx is a documentation generator that is the de facto standard for Python projects. The official documentation can be a bit daunting as it includes so many options, it's hard to know where to start.

Note: This Gist was updated on 04/04/2019 to accomodate a newer version of Sphinx, as well as Python 3.7. YMMV!

This document is written with the following presuppositions:

• You want to leverage the DocStrings in your Python code.
• You'd rather write your DocStrings in Google-style instead of a more awkward reStructuredText format for calling documentation.
