Tagaholic - Demystifying Irb's Commands
Irb is one of the most commonly used standard ruby libraries, yet most don’t seem to know much about it. I’ve lost count of the number of blog posts that explain some irb “tricks†or “secret†config options. This is the first in a series that aims to make irb less magical and more accessible. First off, I’m assuming you know your way around irb some. If you don’t then I recommend reading the pragm
Tagaholic - Lightning - Speed For Your Shell
Introducing lightning, a commandline framework that could revolutionize how fast you are on the commandline. Lightning lets you easily define and generate shell functions which autocomplete and interpret paths (files and directories) by their basenames. With these functions you don’t have to ever type the full path to any file for any command again. Overview Intro Install Lightning Bolts Everythin
Tagaholic - Mini Irb and Mini Script/Console
It’s got the very basics of a repl: take a user’s input, eval it and print the result. Being as basic as it is, there’s no autocompletion, persistent readline history, etc. But who says that needs to be much larger to get those features?: 1 %w{readline rubygems bond}.each {|e| require e } 2 Bond.start 3 history_file = File.join(ENV["HOME"], '.mini_irb_history') 4 IO.readlines(history_file).each {|
Tagaholic - Hirb - And Tables for All
Almost a year ago, hirb started as an itch to get mysql-like tables for Rails’ ActiveRecord models. Now, hirb 0.3.0 provides table views for ten additional database gems. Whether you use hirb with couch, mongo, riak or any of the databases supported by sequel or datamapper, hirb essentially turns irb into a database-agnostic database shell. Database Gems Here are the list of additional database ge
Tagaholic - Boson - Command Your Ruby Universe - Part Deux
With the latest release of Boson, there are a slew of new features that need some explaining. Yes, there is a changelog and documentation, but some of these features are novel enough that a good intro is in order. Overview Here’s an overview of features: Command Options Pipe Options Query Option Libraries Local Libraries Directory-Spaced Libraries Social Libraries Plugin Libraries Invoking Command
Tagaholic - Ruby Reference Commands With Boson
Continuing where this post left off, we’ll look at more examples of the unique command and view framework interaction that Boson and Hirb have. In particular, we’ll look at commands that are useful references to your current Ruby environment. Since Boson’s commands are just methods in a module, any of these commands work fine in irb without Boson. Game Plan We’ll be looking at my ruby_ref library
Tagaholic - How Boson Enhances Your Irb Experience
In previous posts, Boson was introduced as a command framework, usable from the commandline and irb. In this post, we’ll focus on how Boson enhances irb by treating methods like shell commands. Preface If you’re an avid irb user like me, your ~/.irbrc is littered with methods. These methods are sometimes favorite tweaks to Ruby’s core libraries and sometimes interfaces to gems. But regardless of w
Tagaholic - Boson And Hirb Interactions
In the last post, I introduced Boson and its options for commands. What I didn’t mention was that Boson also gives those commands default options. Among them are ones to control rendering a command’s output with Hirb and even toggle rendering. At the flick of a switch, Boson commands (Ruby methods) can have Hirb’s views. Hirb’s Handy Tables Back in an old post, I concluded with a mention that Hirb
Tagaholic - Better Irb Completion With Bond
In the last post I introduced Bond. This post dips further into its completion arsenal to bring you a drop-in enhancement of irb’s completion. Irb has had awesome autocompletion for some time. Bond is here to make it even better. With the latest Bond comes bond/completion, Bond’s enhanced version of irb/completion that is independent of irb. This file is simply a list of predefined Bond completion
