A module for implementing the Service Object pattern that allows for custom "verbs".

Usage

Including CallMe in your class adds a call class method that instantiates an object of the class using the provided arguments and invokes its call method. For example:

The arel_extensions gem has a couple of bugs...

DateSub doesn't work:

(table[:column] - 10.hours).to_sql
# => NoMethodError: undefined method `to_sql' for nil:NilClass

For MySQL, DateAdd generates a double-minus when given a negative duration:

	# frozen_string_literal: true

	module PresenceRefinements
	refine Object do
	def blank? = (respond_to?(:empty?) ? !!empty? : !self)
	def present? = !blank?
	def presence = (self if present?)
	end

	# This bit is cribbed from https://github.com/rpanachi/core_ext

	#!/bin/sh

	# Passes all changed and added files on the current branch to RuboCop before pushing. Paste the below into your
	# .bin/hooks/pre-push file, which should be made executable.
	# Note that it assumes that your trunk branch is named "main." If this is not the case, make the appropriate adjustment.

	TRUNK_BRANCH=main
	CURRENT_BRANCH="$(git branch --show-current)"
	if [ "$CURRENT_BRANCH" != "$TRUNK_BRANCH" ]; then
	rubocop $(git diff --name-status "$TRUNK_BRANCH" "$CURRENT_BRANCH" \| egrep '^[AM]' \| cut -f 2 \| egrep '(^Gemfile\|.rb)$')

	#!/usr/bin/env ruby
	# frozen_string_literal: true

	require "json"
	require "open3"
	require "pathname"
	require "tempfile"

	# Detects intermittent failures in an RSpec test suite and reports on varying
	# coverage.

	# frozen_string_literal: true

	require "active_support/all"
	require "optparse"

	module Options
	extend ActiveSupport::Concern

	included do
	delegate :arguments, :options, to: :Options

	#!/usr/bin/env sh

	# If you don't already have a pre-push hook in your working copy, simply copy
	# this into .git/hooks/pre-push in your working copy. If you already have a
	# pre-push hook, you'll have to integrate it with your existing hook.

	function current_branch {
	git rev-parse --abbrev-ref HEAD
	}
