joemaller / regexp-exec-vs-string-match.md
Created April 21, 2017 14:39
RegExp.exec and String.match are the same, right?

In JavaScript RegExp.exec() and String.match() should be interchangeable so long as the inputs are the same. Right?

const pat = /(dog).*(bird)/g;
const str = 'dog cat bird';

const foo = str.match(pat);
const bar = pat.exec(str);

joemaller / PS1 Color Functions for Shell Prompts.sh
Last active March 9, 2018 21:33
A set of simple color functions to help customize the shell's $PS1 prompt. These wrap the nasty color and background escape codes into more humane functions. Due to shell string escaping oddness, these must be used with `PROMPT_COMMAND` instead of directly in PS1. A complete git-aware .bashrc prompt is here: https://gist.github.com/joemaller/f7d…

# A set of color functions to help with fancy $PS1 prompts
#
# This:
# PROMPT_COMMAND='PS1="\e[32;1m\]\u@\[\e[35;1m\]\H \[\e[0m\]\w]\$ "''
#
# Can be more clearly written as:
# PROMPT_COMMAND='PS1="$(DARK_GREEN \\u@)$(PURPLE \\H) \w]\$ "''
