• Fixed #68: The "cucumber" command now fails early when @solo features fail.
• Added: The "setup" command now prints the db adapter when prompting db credentials.
• Fixed #71: When used without staged changes, the "commit" command will print a warning and create an empty commit. Any arguments to the command are forwarded to Git.
• Fixed: The "commit" command will not print the extra message any more.
• Added: The "commit" command prints a (progre...

Introduction

Most of the time it is a tedious task to apply a code style guide to an existing code base as there are likely to be a lot of conflicts. At makandra we are using makandra-rubocop to have code style checks. Here is some advice on how to add makandra-rubocop efficiently.

Note

RubyMine by default has a Rubocop inspection with rules that we don't always agree with. We recommend replacing this with makandra-rubocop or disabling the inspection.

Capistrano automatically logs each (successful) deployment into a file on your application servers.

It is located at the root of your server's project folder, i.e. the parent of releases and current, like so:

/var/www/your-project$ ls
current
log
releases
repo
revisions.log  <---  here
shared

Each line in that file contains the deployed branch, commit, release ID, and username (was read from the deploying user's machine):

$ tail -n3 revisions.log 
Branch master (at da45511bea63002ac2ff002d1692e09d0dd7cb88) deployed as rel...

Sometimes, due to git or other "accidents", important files get deleted or overwritten.

At a state when even Ctrl+Z doesn't work anymore, you maybe can rescue your files with RubyMines "Local History"-Feature!

To do this try the following:

• If the file got deleted, recreate a new empty file with the same name on the exact same place
• Open that file in the editor
• Go to RubyMine and click on VCS -> Local History -> Show History
• In the now open window, you should see all greater changes made to the File, even before it got deleted/temp...

webpack is a very powerful asset bundler written in node.js to bundle (ES6) JavaScript modules, stylesheets, images, and other assets for consumption in browsers.

Webpacker is a wrapper around webpack that handles integration with Rails.

This is a short introduction.

Installation

If you haven't already, you need to install node.js and Yarn.

Then, put

gem 'webpacker', '~> 4.x' # check if 4.x is still cu...

git apply allows you to apply a diff onto your HEAD. Most often you can achieve the same result with a rebase & merge.

Example:

master                commit1 - commit3
feature-branch                \ commit2 - commit4

git checkout feature-branch
git reset --hard commit3
git diff ..commit4 | git apply

master                commit1 - commit3
feature-branch                          \ Unstaged commit 2 & 4

You can also [create a patch and apply it afterwards](https://makandracards.com/makandra/2521-git-how-to...

If rspec hangs with no output and you dont get a backtrace neither with --backtrace nor by just killing it with crtl-c,
you can put the following in your spec/spec_helper.rb:

puts "rspec pid: #{Process.pid}"

trap 'USR1' do
  threads = Thread.list

  puts
  puts "=" * 80
  puts "Received USR1 signal; printing all #{threads.count} thread backtraces."

  threads.each do |thr|
    description = thr == Thread.main ? "Main thread" : thr.inspect
    puts
    puts "#{description} backtrace: "
    puts thr.backtrace.join("\n")
  end

The issue in this card can occur if the node_modules directory is checked into your Git repository. We usually recommend to exclude node_modules from version control.

In any case you should document which version of node to use in your project in a .nvmrc file.

I saw a strange behaviour after we introduced webpack in one of our projects and finally found out the reason: The person who committed the files used a node version that is older than mine.

Every time I wanted to run my rai...

This is a short overview of things that are required to upgrade a project from the Asset Pipeline to Webpacker. Expect this upgrade to take a few days even the diff is quite small afterwards.

Preparations

1. Find all libraries that are bundled with the asset pipeline. You can check the application.js and the application.css for require and import statements. The source of a library is most often a gem or a vendor directory.
2. Find an working example for each library in the application and write it down.
3. Find out the ver...

Summary

• We want to move away from jQuery in future projects
• Motivations are performance, bundle size and general trends for the web platform.
• The native DOM API is much nicer than it used to be, and we can polyfill the missing pieces
• Unpoly 0.60.0 works with or without jQuery

Is jQuery slow?

When upgrading Rails versions -- especially major versions -- you will run into a lot of unique issues, depending on the exact version, and depending on your app.

However, it is still possible to give some generic advice on how you want to tackle the update in principle.

If you are not really confident about upgrading Rails, have a look at Rails LTS.

How many update steps?

Besides the Rails upgrade itself, you might also want to upgrade your other gems and upgrade your Ruby version.
First decide in how many st...

S3cmd is a free command line tool and client for uploading, retrieving and managing data in Amazon S3. S3cmd reads its configuration by default from ~/.s3cfg, which is created once you run s3cmd --configure.

If you have many configurations, we recommend to always specify the configuration you want to use. This prevents applying actions to the wrong bucket.

Examples:

s3cmd -c ~/.s3cfg-github-staging ls
s3cmd -c ~/.s3cfg-github-development ...

Normally you can list all gems of the current ruby version with gem list, which also includes the gems of you Gemfile. These can be uninstalled with gem uninstall gemname.

List and uninstall a gem installed via Bundler from Github

This does not work for gems installed directly from Github. They do not appear in gem list.

Show all gems installed via Github by bundler:

ls ~/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/bundler/

Remove a gem installed via Github by Bundler:

rm -rf ~/.rbenv/versions/2.4.1/lib/ruby/gems/2....

In this example we assume that not only the storage gem changes but also the file structure on disc.

A general approach

Part A: Create a commit which includes a script that allows you to copy the existing file to the new file structure.

Part B: Create a commit which removes all paperclip logic and replace it with the same code you used in the first commit

Part A

Masonry is a famous library to dynamically arrange a grid of items that have different aspect ratio, like horizontal and vertical images.
Colcade is an alternative masonry-layouting library, developed by the same developer, but with a more modern approach.

It is said to have better performance while being smaller and having no dependencies. It automagically detects jQuery and defines a jQuery initializer, if present.
However, it offers [a few less features](https:...

Geordi provides a pretty neat way to generate beautiful commit messages according to your stories in Linear:

geordi commit

Geordi reads from a .geordi.yml file inside your repo and connects to Linear to list started and finished stories with their title. Choosing one of them generates a commit message including id and title from Linear app and a link to the original issue. For example:
