Showing off your dotfiles
With the introduction of my first Apple laptop a few years ago, my home computers went from being half Unix-like (I had a healthy mix of Linux and Windows machines) to mainly (two thirds) Unix-like. With it came a change in the kind of software I use on a daily basis and an increased need to synchronize the configuration of those programs between my machines.
Enter the “dotfiles community”: an informal group of people who, as Zach Holman puts it, think that “dotfiles are meant to be forked”.
“Dotfiles” are rooted in Unix culture – the name refers to the configuration files starting with a dot that clutter your home directory like crazy. This means you will mostly find Mac and Linux users in there (that’s ok, they’re pretty nice… usually), but to me it’s mostly about putting all your configuration files in source control in a way that makes it easy to setup new machines and share with others.
So like everybody else, I put my dotfiles out there for anyone to poke around. They’re mostly boring, but you may find a few useful things, like those I outline below (after the break). Nothing earth-shattering, but if it saves you the 15 minutes needed to write it, that’s 15 minutes you can spend on doing actual stuff.
Most people store their dotfiles in a Git or Mercurial repository, and then create symlinks from their home directory into the repo (like, for instance, linking
$HOME/DotFiles/vim/.vimrc). Because I also need some of those configuration files on Windows, I can’t really hard-code paths like this.
As a result, I opted for generating some of my dotfiles when I run my install script. Those dotfiles mostly only include the real ones from the repo. This lets me clone my dotfiles repo anywhere I want – no need to hard-code anything.
Mercurial config includes
An often overlooked feature of Mercurial’s config files is the
%include statement which lets you include other config files. This lets me specify OS-specific config files to my
hgrc, and even optionally have a local config file (since the
%include statement will quietly fail if the included file doesn’t exist).
Cross-platform, multi-language Vim
If you’re running Vim on both MacOS and Windows, you may be interested in a few lines from my
.vimrc, like when it figures out the directory for all the Vim runtime files (
.vim on MacOS,
vimfiles on Windows).
You may also be interested in a couple of international features I have:
- A mapping to switch keyboard layouts in input mode (I switch between English and French)
- A mapping to switch spell-checking on and off, and the language it will be checking against is in sync with the input mode keyboard layout.
That’s it! I hope somebody finds it helpful in some way.
