basher

A package manager for shell scripts and functions.

Basher allows you to quickly install shell packages directly from github (or other sites). Instead of looking for specific install instructions for each package and messing with your path, basher will create a central location for all packages and manage their binaries for you.

Even though it is called basher, it also works with zsh and fish.

Installation

Checkout basher on ~/.basher

$ git clone https://github.com/basherpm/basher.git ~/.basher

Add ~/.basher/bin to $PATH for easy access to the basher command-line utility.
```
$ echo 'export PATH="$HOME/.basher/bin:$PATH"' >> ~/.bash_profile
```
Ubuntu Desktop note: Modify your ~/.bashrc instead of ~/.bash_profile.

Zsh note: Modify your ~/.zshrc file instead of ~/.bash_profile.

For Fish: Add the following to you ~/.config/fish/config.fish
```
if test -d ~/.basher
  set basher ~/.basher/bin
end
set -gx PATH $basher $PATH
```
Add basher init to your shell to enable basher runtime functions
```
$ echo 'eval "$(basher init -)"' >> ~/.bash_profile
```
Same as in previous step, use ~/.bashrc on Ubuntu, ~/.zshrc for Zsh.

For Fish, use the following line on your ~/.config/fish/config.fish.
```
status --is-interactive; and . (basher init -|psub)
```

Updating

Run basher update to update basher.

Usage

Installing packages from github.com

$ basher install sstephenson/bats

This will install bats from https://github.com/sstephenson/bats and add bin/bats to the PATH.

Installing packages from other sites

$ basher install bitbucket.org/user/repo_name

This will install repo_name from https://bitbucket.org/user/repo_name

Using ssh instead of https

If you want to do local development on installed packages and you have ssh access to the site, use --ssh to override the protocol:

$ basher install --ssh juanibiapina/gg

Installing a local package

If you develop a package locally and want to try it through basher, use the link command:

$ basher link directory my_namespace/my_package

The link command will install the dependencies of the local package. You can prevent that with the --no-deps option:

$ basher link --no-deps directory my_namespace/my_package

Sourcing files from a package into current shell

Basher provides an include function that allows sourcing files into the current shell. After installing a package, you can run:

include username/repo lib/file.sh

This will source a file lib/file.sh under the package username/repo.

Command summary

basher commands - List commands
basher help <command> - Display help for a command
basher uninstall <package> - Uninstall a package
basher update - Update basher to latest version from master
basher list - List installed packages
basher outdated - List packages which are not in the latest version
basher upgrade <package> - Upgrade a package to the latest version

Configuration options

To change the behavior of basher, you can set the following variables either globally or before each command:

BASHER_FULL_CLONE=true - Clones the full repo history instead of only the last commit (useful for package development)
BASHER_PREFIX - set the installation and package checkout prefix (default is $BASHER_ROOT/cellar). Setting this to /usr/local, for example, will install binaries to /usr/local/bin, manpages to /usr/local/man, completions to /usr/local/completions, and clone packages to /usr/local/packages. This allows you to manage "global packages", distinct from individual user packages.

Packages

Packages are simply repos (username/repo). You may also specify a site (site/username/repo).

Any files inside a bin directory are added to the path. If there is no bin directory, any executable files in the package root are added to the path.

Any manpages (files ended in \.[0-9]) inside a man directory are added to the manpath.

Optionally, a repo might contain a package.sh file which specifies binaries, dependencies and completions in the following format:

BINS=folder/file1:folder/file2.sh
DEPS=user1/repo1:user2/repo2
BASH_COMPLETIONS=completions/package
ZSH_COMPLETIONS=completions/_package

BINS specified in this fashion have higher precedence then the inference rules above.

Development

To run the tests, install bats:

$ basher install sstephenson/bats

update submodules:

$ git submodule update --init

and then run:

$ make

mrjk / basher
