Common Case Transformation Snippets

Visual Studio Code allows Snippets to perform ✨Variable Transforms✨ using Regex.

Here are some common case transformations that you can apply to your snippets. In these examples, I'm using $TM_FILENAME_BASE, but the same transformations should apply to any of the Snippet Variables.

snippets-from-delimited.json can convert filenames like my-file-name, my_file_name, my file name. If your filename is delimited by a dash, underscore, or space, these should work.

snippets-from-mixed-case.json can convert filenames like myFileName and MyFileName. If your filename is in camel or Pascal case, these should work.

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)

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

# Matches a state to its timezone (if it has only one).
#
# Commented out fields mean that the state 
# has multiple timezones or was unknown at the time.

Things I believe

This is a collection of the things I believe about software development. I have worked for years building backend and data processing systems, so read the below within that context.

Keep it simple, stupid. You ain't gonna need it.
