Created March 17, 2019 00:29
Handle errors in all Discord commands with discordrb (also formats those errors while only keeping the path in the stacktrace relative to the project's root) (only Rails.root is Rails-specific, rest is pure ruby)
module Discord
module Commands
extend Discordrb::Commands::CommandContainer
def self.handle_errors(e)
if e.is_a?(Discordrb::Errors::MessageTooLong)
"Message too long"
else
str = "#{Format.inline(e.message}\n"
str += Format.code(e.backtrace.grep(/#{Rails.root.to_s}/).map { |s| s.gsub(Rails.root.to_s, "") }.join("\n"))

Rails ActiveRecord#select vs #pluck, 5x faster (~20k records, 10 runs each)

Benchmark.bm do |x|
