Terminal, Editor and Shell Geekery

It’s been a busy few months and I am lucky to be learning lots through work and other projects, though somewhat failing to share interesting stuff here! Anyway, inspired by watching one of my friends use a computer almost exclusively sans mouse/trackpad, and by a test-driven development kata on which Mark Withall and I are working [I should make a separate post on this soon], I wanted to get more productive with my coding.

Terminal

The first step was to move to iTerm2 which allows me to have a full-screen terminal window with three panes: a full-height left-hand one for code; a top-right one for revision control and a bottom-right one continually running tests in a loop.

I need rather large text, so there’s a bit of a trade-off between pane widths, though I try to ensure they’re all at least 80 by 25 characters if possible.

Editor

I’ve been using Vim since my undergrad year in industry, where it made short work of manipulating large volumes of text-based data, but I’ve never really grokked it. Recently I’ve cranked my Vim config up to eleven using the excellent Vundle and several plugins such as

and I’m looking forward to becoming proficient with these and more in due course! When smoothly rocking along with Vim, it seems a good idea to thoroughly check out Emacs again in order to pick things up from a different perspective.

Some have asked why I don’t move into the 21st century—maybe I should try some more modern editors, but for me (and it seems others) Vim still offers a clean, yet also helpful and productive development environment and I do enjoy its modal nature, keyboard-centricity, malleability and aesthetic. Also I love that, whilst so many systems, platforms and hardware/software standards have come and gone, we can still rely on these trusty tools (along with serial ports, who still KBO)—it’s almost as if I’m a “real hacker”, not just out of obsession with the supposed quaint or eccentric, but because these tools seriously deliver the goods.

Shell

Another change I’ve made, with a helpful nudge from my colleague Karl Groves and a presentation I read online, is to move to zsh from Bash (which taught me so much and I have enjoyed and relied on for many years). There is a great distribution of configuration, themes and plugins for zsh called oh-my-zsh but so far I’ve decided to roll my own config, drawing a lot from the examples there and in the manual and tutorials many others have written. So far I’m really enjoying…

Whilst Bash is still awesome, I’m enjoying the way that zsh works—though all this exploration of shells has also lead me to discover fish, which sounds compelling (it has a sort-of “there’s only one way to do it”/”it just works” philosophy and even includes syntax highlighting); when my zsh config has settled, I intend to explore fish, too.

Powerline

I was blown away by the striking, yet simple and informative agnoster theme for zsh and wondered if those techniques and aesthetic could be applied elsewhere; eventually I discovered Powerline (there are lighter-weight related projects, for those who are interested) and find it compelling—something to check out when my .zshrc et al a bit more solid…

My Dotfiles GitHub Repo

Like many others (whom I’ve shamelessly copied in terms of repo structure) I have put my dotfiles on GitHub for easy set-up across boxen. I have tried to document them (particularly the zsh and Vim stuff) and I hope you find something useful in there.
