Pipe child process stdout and stderr to main process in Ruby
Open3.popen3("./tmp.sh") do |stdin, stdout, stderr, wait_thr|
# Stream output
# DEV: We'd like to stream both `stderr` and `stdout` but it was getting troublesome
# with `.alive?` and `gets()` blocking each other
while line = stdout.gets()
$stdout.puts(line)
end
# Finish any last stderr or stdout
stdout_remainder = stdout.read()

Increment CFBundleVersion script, generally reusable for incrementing version in bash
#!/usr/bin/env bash
# Exit on first error, unset variable, or pipe failure
set -euo pipefail
# Define our constants
PLIST_FILEPATH="path/to/plist.plist"
# Resolve our version being deployed
# https://gist.github.com/sekati/3172554
# DEV: `plutil` doesn't support extraction easily (could use `-o -` but it's wrapped in XML/binary/JSON)

Xcode customizations

It's my first time setting up Xcode but I want to keep track of my preferences (probably move it to a dotfile if it becomes serious). Here's our notes:

  • Navigation
    • Navigation: Uses Focused Editor
  • Fonts & Colors
    • Theme: Default
  • Text Editing
    • Editing
      • Page guide at column: 120
  • Source Control

Replace Gratipay content with support me page

I've been adding Gratipay to my README's for a long time. As a result of Gratipay shutting down, I need to update all of my README content. Here's my strategy:

                RAILS_ENV overloading with `bin/rake` and `config/boot.rb`
              
          

        

      

        

  

      

    
We are using dotenv with Rails and Spring but running into timing issues where Dotenv loads/assumes we're in development before RSpec can override RAILS_ENV


To prevent this from happening consistently, we've added a patch in bin/rake and config/boot.rb


We verified our patch works with puts in spec/rails_helper.rb:


puts("RAILS_ENV", ENV["RAILS_ENV"])
puts("S3_REGION", ENV["S3_REGION"])
ENV["RAILS_ENV"] ||= "test"

File structure


We are using BEM notation for our filenames where the "block" is our proof and "element" is the equation in the proof. For example:


    

  • "projection__cosTheta-equals-axisLength.tex" has proof "projection" and step "cosTheta-equals-axisLength"

      

    • We try to use camelCasing to associate relevant terms (e.g. length, operations, functions)
      •
