Failsafe

When something goes wrong I want to degrade the user experience (instead of returning a 500 - Server Error) And I want to be notified about the failure

Usage

Wrap non mission critical code:

pcreux

#!/usr/local/env ruby
#
# Generate html traces from CircleCI workflows
#

require 'json'
require 'http'

OWNER = 'githubowner'
REPO = 'githubrepo'

pcreux

#!/usr/bin/env ruby
#
# Run `bundle outdated | format_bundle_outdated`
# to get a CSV file listing the columns below for all outdated gems.

COLUMNS =  [ "name", "newest", "installed", "requested", "groups", "delta" ].join(",")

class Version < Struct.new(:major, :minor, :patch, :beta)
  def self.build(string)
    new(*string.split('.').map(&:to_i))

# no ruby gems required

pcreux

#!/bin/sh
# Extract all new migrations from the current branch over to a new branch (suffixed with "-migration")

set -ev

export branch=`git rev-parse --abbrev-ref HEAD`
git checkout master
git pull
git checkout -b $branch-migration
git checkout $branch -- db engines/*/db

#!/usr/bin/env ruby
# Run unit test for all added or changed app, lib and test files.

# * `rtt master` will run tests for all files different from master

if ARGV[0]
  files = `git diff --name-only $(git merge-base HEAD #{ARGV[0]})..$(git rev-parse --abbrev-ref HEAD)`.split("\n")
else
  files = `git status -s`.split("\n").map { |f| f.split(' ').last }
