shin

Manage those dotfiles and shell snippets like a human, you dirty ape.

OK, so what?

shin is a simple package manager geared towards wrangling all those dotfile fragments, shell functions, and other crap you've got stuck in .profile, .bash_profile, and their friends right now. Instead of a giant file of death, you can now separate them into neat, versionable little packages.

Installation

To install shin, simply run the install.sh file from the repo. You can do so like this:

wget https://raw.github.com/jm/shin/master/install.sh
sh install.sh

Or if you're feeling risky:

curl https://raw.github.com/jm/shin/master/install.sh | sh

The install will do three things:

  • Create a directory in your home directory named .shin
  • Clone a copy of shin to .shin/system
  • Install a small little initializer snippet into the bottom of your .profile

Once that's finished up, you should be good to go.

Usage

The commands are fairly straightforward:

Installing packages from Git

To install a package into shin, it must be built to work with shin (see information on package format below; it's simple!). Once you've got a Git repository you'd like to install from, you can install from it in a couple of ways using the .install command (aliased as shin install). If it's a GitHub repository, you can simply give shin the owner/repo format like so:

mymachine$ .install jm/silly

You can also give it a Git repo URL straight up if you want:

mymachine$ .install git://github.com/jm/silly.git

If the package you want to install is hosted on Gist (you can have multiple files in the repo, remember?), you can give shin the repo URL or you can give it a Gist number:

mymachine$ .install 12345

Updating via Git

Updating a package will go to its origin and pull the master branch (I may support other branches later or something, but it's an unlikely addition unless someone makes a compelling patch). To update a package, run the .update command (aliased as shin update) followed by the package name:

mymachine$ .update silly

Installing packages via HTTP

You can also create ad hoc packages by installing scripts from a URL. Simply feed the .install command or its alias an HTTP URL rather than a Git URL:

mymachine$ .install http://myscripts.com/myscript.sh

That will create a myscript package from the contents of that URL. If given a second argument (e.g., .install http://myscripts.com/myscript.sh lololol), shin will name the package as the second argument.

Updating via HTTP

To update an HTTP package, simply run .update package-name. shin stores the URL for the script in the package, so it knows where to go and fetch a new version from.

Uninstalling

To uninstall a package, simply run the .uninstall (aliased as shin uninstall also) command followed by the package name:

mymachine$ .uninstall silly

Listing packages

To get a list of all packages, run .list (or shin list). One day I'll support in-list searching, but that's pretty far down the list.

Setting your prompt

Some packages provide a special prompt you can activate. Let's say you had a nice Git package that had a special prompt for managing bisects. You might activate it like so:

.ps1 awesome-git-package-name

You can also activate the special prompts with the .prompt or shin ps1 commands.

Initializing

If you choose to remove the shell initializer from your .profile, you can init the shin environment by running shin init.

The bucket

shin also has the concept of a "bucket" package. This package is basically just a holder for any random snippets or code you want to place in there. To edit your bucket file directly in your default editor, simply run shin bucket.

Anatomy of a package

A (non-ad-hoc) shin package is simply a Git repository with a few special files:

* A `shinit.sh` file (required)
* Your code (either in the `shinit.sh` or sourced from there)
* A `.shin_description` file that is a short description of the package
* An optional `ps1.sh` that will chnage a user's prompt (PS1)

That's all! The shinit.sh file is where the magic happens. If you need to source anything from there, simply use the $package_path variable the loader will expose to your script to source things in the package's path:

source $package_path/this_file.sh

Otherwise, you can put everything in the shinit.sh file. You should include a .shin_description file since one day I may build out an index for these things. For an example of the smallest (useful) package, check out my serve package at https://github.com/jm/serve.

Removing from your system

To remove shin, simply delete ~/.shin and remove the lines added by shin to your .profile.

Contributing and such

Feel free to file issues in the issue tracker here on GitHub; pull requests are, of course, accepted (especially if I've done something stupid in Bash; a shell programmer, I am not).

As for things to add, here's a quick list:

  • Move description and dependency information into a .shinfo file instead of separate files
  • Build out a ridiculously simple index service that simply has an API for pointing to repos
  • Dependencies would be nice
  • RVM Gemset-like functionality. Much of the infrastructure is there (segmenting into sets, mapping functions added by a package, etc.); there's just a bit more groundwork to lay
Something went wrong with that request. Please try again.
