Build Awesome Command-Line Applications in Ruby: Control Your Computer, Simplify Your Life by David B. Copeland

Chris Wanstrath, database schema, en.wikipedia.org, full stack developer, Ruby on Rails, web application

They include Paul Barry, Daniel Bretoi, Trevor Burnham, Ian Dees, Avdi Grimm, Wynn Netherland, Staffan Nöteberg, Noel Rappin, Eric Sendlebach, Christopher Sexton, and Matt Wynne. Finally, I’d like to thank the many programmers who’ve contributed to the open source projects I mention in the book, including, but probably not limited to, the following: Aslak Hellesøy, TJ Holowaychuk, Ara Howard, Yehuda Katz, James Mead, William Morgan, Ryan Tomayko, Chris Wanstrath, and, of course Yukihiro “Matz” Matsumoto, who created such a wonderful language in which to write command-line apps. With all that being said, let’s get down to business and start making our command-line apps a lot more awesome!

However, although you could bundle a man page with your Ruby command-line app, man wouldn’t be able to access it easily because of the way RubyGems installs apps (we’ll talk more about RubyGems in Chapter 7, ​Distribute Painlessly​). Even if man could access your app’s files, creating a man page is no small feat; it requires using the nroff[20] format, which is cumbersome to use for writing documentation. Fortunately, the Ruby ecosystem of open source libraries has us covered. gem-man,[21] a plug-in to RubyGems created by GitHub’s Chris Wanstrath, allows users to access man pages bundled inside a gem via the gem man command. ronn [22] is a Ruby app that allows us to create man pages in plain text, without having to learn nroff. We can use these two tools together to create a manual page that we can easily distribute with our app and that will be easily accessible to our users. Once we’ve installed these tools, created our man page, and distributed our app to users, they’ll be able to read whatever detailed documentation we’ve provided like so: ​$ gem man db_backup​ ​DB_BACKUP.RB(1) DB_BACKUP.RB(1)​ ​​ ​NAME​ ​ db_backup.rb - backup one or more MySQL databases​ ​​ ​SYNOPSIS​ ​ db_backup.rb database_name​ ​ db_backup.rb -u username -p password database_name​ ​ db_backup.rb -i|--iteration database_name​ ​etc....​

Pro Git by Scott Chacon

Chris Wanstrath, continuous integration, creative destruction, Debian, distributed revision control, GnuPG, pull request, revision control

If you want to see what you’ve staged that will go into your next commit, you can use git diff --cached. (In Git versions 1.6.1 and later, you can also use git diff --staged, which may be easier to remember.) This command compares your staged changes to your last commit: $ git diff --cached diff --git a/README b/README new file mode 100644 index 0000000..03902a1 --- /dev/null +++ b/README2 @@ -0,0 +1,5 @@ +grit + by Tom Preston-Werner, Chris Wanstrath + http://github.com/mojombo/grit + +Grit is a Ruby library for extracting information from a Git repository It’s important to note that git diff by itself doesn’t show all changes made since your last commit — only changes that are still unstaged. This can be confusing, because if you’ve staged all of your changes, git diff will give you no output. For another example, if you stage the benchmarks.rb file and then edit it, you can use git diff to see the changes in the file that are staged and the changes that are unstaged: $ git add benchmarks.rb $ echo '# test line' >> benchmarks.rb $ git status # On branch master # # Changes to be committed: # # modified: benchmarks.rb # # Changed but not updated: # # modified: benchmarks.rb # Now you can use git diff to see what is still unstaged $ git diff diff --git a/benchmarks.rb b/benchmarks.rb index e445e28..86b2f7c 100644 --- a/benchmarks.rb +++ b/benchmarks.rb @@ -127,3 +127,4 @@ end main() ##pp Grit::GitRuby.cache_client.stats +# test line and git diff --cached to see what you’ve staged so far: $ git diff --cached diff --git a/benchmarks.rb b/benchmarks.rb index 3cb747f..e445e28 100644 --- a/benchmarks.rb +++ b/benchmarks.rb @@ -36,6 +36,10 @@ def main @commit.parents[0].parents[0].parents[0] end + run_code(x, 'commits 1') do + git.commits.size + end + run_code(x, 'commits 2') do log = git.commits('master', 15) log.size Committing Your Changes Now that your staging area is set up the way you want it, you can commit your changes.

A nice way of quickly getting a sort of changelog of what has been added to your project since your last release or e-mail is to use the git shortlog command. It summarizes all the commits in the range you give it; for example, the following gives you a summary of all the commits since your last release, if your last release was named v1.0.1: $ git shortlog --no-merges master --not v1.0.1 Chris Wanstrath (8): Add support for annotated tags to Grit::Tag Add packed-refs annotated tag support. Add Grit::Commit#to_patch Update version and History.txt Remove stray `puts` Make ls_tree ignore nils Tom Preston-Werner (4): fix dates in history dynamic version method Version bump to 1.0.2 Regenerated gemspec for version 1.0.2 You get a clean summary of all the commits since v1.0.1, grouped by author, that you can e-mail to your list.

You end up with a virtuous cycle for the rapid learning and improving of software programs that drives innovation faster and faster. Originally founded by three grade-A geeks—Tom Preston-Werner, Chris Wanstrath, and P. J. Hyett—GitHub is now the world’s largest code host. Since I could not visit any major company today without finding programmers using the GitHub platform to collaborate, I decided I had to visit the source of so much source code at its San Francisco headquarters. By coincidence, I had just interviewed President Barack Obama in the Oval Office about Iran a week earlier. I say that only because the visitor lobby at GitHub is an exact replica of the Oval Office, right down to the carpet! They like to make their guests feel special. My host, GitHub’s CEO, Chris Wanstrath, began by telling me how the “Git” got into GitHub. Git, he explained, is a “distributed version control system” that was invented in 2005 by Linus Torvalds, one of the great and somewhat unsung innovators of our time.

At General Electric, a big thanks to William Ruh and Megan Parker both for the ideas they shared and for all the GE engineers to whom they introduced me. At Walmart, Doug McMillon, Neil Ashe, Dan Toporek, and their colleagues showed me in exacting detail every digital interaction that happened behind the scenes when I tried to buy a television from Walmart’s mobile app. They also introduced me to the best ribs in Arkansas. I am deeply indebted to Doug Cutting from Hadoop and Chris Wanstrath from GitHub for patiently walking me through the evolution of both of their companies and ensuring that I got every fact right. It took multiple visits and follow-ups with both for me to fully understand what they had each helped to create, and I am extremely grateful for their tutoring. Qualcomm’s cofounder Irwin Jacobs did the same on my two visits to his campus. He, his son Paul, and their whole team were enormously generous with their time.

Yet when interviewers asked the same question of those companies’ systems administrators, 95 percent answered yes, an outcome that led IBM to make a major strategic shift into open source. Celebrated—even recognized—or not, open source software runs the Internet (and thus the world) today. After that extraordinary initial success, the open source movement settled into a stable, stratified environment over much the last decade, with the community producing little in the way of new innovation. Everything changed in 2008, however, when Chris Wanstrath, P.J. Hyett and Tom Preston-Werner (all out of Paul Graham’s Y Combinator entrepreneurial incubator program) founded a company called GitHub. An open source coding and collaboration tool and platform, GitHub has utterly transformed the open source environment. It is a social network for programmers in which people and their collaborations are central, rather than just the code itself. When a developer submits code to a GitHub project, that code is reviewed and commented upon by other developers, who also rate that developer.

The first issue of Model View Culture, which was published in January 2014, is available online. For more context, in 2014, Astra Taylor and I co-wrote an essay for The Baffler on sexism and Silicon Valley, “The Dads of Tech.” The TechCrunch report “Julie Ann Horvath Describes Sexism and Intimidation Behind Her GitHub Exit” was authored by Alex Wilhelm and Alexia Tsotsis (March 18, 2014). GitHub hired a third-party investigator to look into Horvath’s allegations. Chris Wanstrath published the findings on the company blog on April 28, 2014 (“Follow up to the investigation results”). The investigator found that “Tom Preston-Werner in his capacity as GitHub’s CEO acted inappropriately, including confrontational conduct, disregard of workplace complaints, insensitivity to the impact of his spouse’s presence in the workplace, and failure to enforce an agreement that his spouse should not work in the office.”

Using EJS to add templating capabilities to the client side You’ve now learned how to use a fully featured Node template engine, so it’s time to look at the Hogan template engine, which deliberately limits the functionality available to templating code. 11.3. Using the Mustache templating language with Hogan Hogan.js (https://github.com/twitter/hogan.js) is a template engine that was created by Twitter for its templating needs. Hogan is an implementation of the popular Mustache (http://mustache.github.com/) template language standard, which was created by GitHub’s Chris Wanstrath. Mustache takes a minimalist approach to templating. Unlike EJS, the Mustache standard deliberately doesn’t include conditional logic, nor any built-in content-filtering capabilities other than escaping content to prevent XSS attacks. Mustache advocates that template code should be kept as simple as possible. In this section you’ll learn How to create and implement Mustache templates in your application The different template tags available in the Mustache standard How to organize your templates using “partials” How to fine-tune Hogan with your own delimiters and other options Let’s look at the alternative approach Hogan provides for templating. 11.3.1.
