Cygwin

The core of Babun consists of a pre-configured Cygwin. Cygwin is a great tool, but there’s a lot of quirks and tricks that makes you lose a lot of time to make it actually usable. Not only does babun solve most of these problems, but also contains a lot of vital packages, so that you can be productive from the very first minute.

Package manager

Babun provides a package manager called pact. It is similar to apt-get or yum. Pact enables installing/searching/upgrading and deinstalling cygwin packages with no hassle at all. Just invoke pact --help to check how to use it.

Shell

Babun’s shell is tweaked in order to provide the best possible user-experience. There are two shell types that are pre-configured and available right away - bash and zsh (zsh is the default one). Babun’s shell features:

syntax highlighting
UNIX tools
software development tools
git-aware prompt
custom scripts and aliases
and much more!

Console

Mintty is the console used in babun. It features an xterm-256 mode, nice fonts and simply looks great!

Proxying

Babun supports HTTP proxying out of the box. Just add the address and the credentials of your HTTP proxy server to the .babunrc file located in your home folder and execute source .babunrc to enable HTTP proxying. SOCKS proxies are not supported for now.

Developer tools

Babun provides many packages, convenience tools and scripts that make your life much easier. The long list of features includes:

programming languages (Python, Perl, etc.)
git (with a wide variety of aliases and tweaks)
UNIX tools (grep, wget, curl, etc.)
vcs (svn, git)
oh-my-zsh
custom scripts (pbcopy, pbpaste, babun, etc.)

Plugin architecture

Babun has a very small microkernel (cygwin, a couple of bash scripts and a bit of a convention) and a plugin architecture on the top of it. It means that almost everything is a plugin in the babun’s world! Not only does it structure babun in a clean way, but also enables others to contribute small chunks of code. Currently, babun comprises the following plugins:

cacert
core
git
oh-my-zsh
pact
cygdrive
dist
shell

Auto-update

Self-update is at the very heart of babun! Many Cygwin tools are simple bash scripts - once you install them there is no chance of getting the newer version in a smooth way. You either delete the older version or overwrite it with the newest one losing all the changes you have made in between.

Babun contains an auto-update feature which enables updating both the microkernel, the plugins and even the underlying cygwin. Files located in your home folder will never be deleted nor overwritten which preserves your local config and customizations.

Installer

Babun features an silent command-line installation script that may be executed without admin rights on any Windows hosts.

Using babun

Setting up proxy

To setup proxy uncomment following lines in the .babunrc file (%USER_HOME%\.babun\cygwin\home\USER\.babunrc)

# Uncomment this lines to set up your proxy
# export http_proxy=http://user:password@server:port
# export https_proxy=$http_proxy
# export ftp_proxy=$http_proxy
# export no_proxy=localhost

Setting up git

Babun has a pre-configured git. The only thing you should do after the installation is to add your name and email to the git config:

git config --global user.name "your name"
git config --global user.email "your@email.com"

There’s a lot of great git aliases provided by the git plugin:

gitalias['alias.cp']='cherry-pick'
gitalias['alias.st']='status -sb'
gitalias['alias.cl']='clone'
gitalias['alias.ci']='commit'
gitalias['alias.co']='checkout'
gitalias['alias.br']='branch'
gitalias['alias.dc']='diff --cached'
gitalias['alias.lg']="log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %Cblue<%an>%Creset' --abbrev-commit --date=relative --all"
gitalias['alias.last']='log -1 --stat'
gitalias['alias.unstage']='reset HEAD --'

Installing and removing packages

Babun is shipped with pact - a Linux like package manager. It uses the cygwin repository for downloading packages:

{ ~ } » pact install arj                                                                     ~
Working directory is /setup
Mirror is http://mirrors.kernel.org/sourceware/cygwin/
setup.ini taken from the cache

Changing the default shell

The zsh (with .oh-my-zsh) is the default babun’s shell.

Executing the following command will output your default shell:

{ ~ } » babun shell                                                                          ~
/bin/zsh

In order to change your default shell execute:

{ ~ } » babun shell /bin/bash                                                                ~
/bin/zsh
/bin/bash

The output contains two lines: the previous default shell and the new default shell

Checking the configuration

Execute the following command the check the configuration:

{ ~ }  » babun check                                                                         ~
Executing babun check
Prompt speed      [OK]
Connection check  [OK]
Update check      [OK]
Cygwin check      [OK]

By executing this command you can also check whether there is a newer cygwin version available:

{ ~ }  » babun check                                                                            ~
Executing babun check
Prompt speed      [OK]
Connection check  [OK]
Update check      [OK]
Cygwin check      [OUTDATED]
Hint: the underlying Cygwin kernel is outdated. Execute 'babun update' and follow the instructions!

It will check if there are problems with the speed of the git prompt, if there’s access to the Internet or finally if you are running the newest version of babun.

The command will output hints if problems occur:

{ ~ } » babun check                                                                          ~
Executing babun check
Prompt speed      [SLOW]
Hint: your prompt is very slow. Check the installed 'BLODA' software.
Connection check  [OK]
Update check      [OK]
Cygwin check      [OK]

On each startup, but only every 24 hours, babun will execute this check automatically. You can disable the automatic check in the ~/.babunrc file.

Tweaking the configuration

You can tweak some config options in the ~/.babunrc file. Here’s the full list of variables that may be modified:

# JVM options
export JAVA_OPTS="-Xms128m -Xmx256m"

# Modify these lines to set your locale
export LANG="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"

# Uncomment these lines to the set your machine's default locale (and comment out the UTF-8 ones)
# export LANG=$(locale -uU)
# export LC_CTYPE=$(locale -uU)
# export LC_ALL=$(locale -uU)

# Uncomment this to disable daily auto-update & proxy checks on startup (not recommended!)
# export DISABLE_CHECK_ON_STARTUP="true"

# Uncomment to increase/decrease the check connection timeout
# export CHECK_TIMEOUT_IN_SECS=4

# Uncomment this lines to set up your proxy
# export http_proxy=http://user:password@server:port
# export https_proxy=$http_proxy
# export ftp_proxy=$http_proxy
# export no_proxy=localhost

Updating babun

To update babun to the newest version execute:

babun update

Please note that your local configuration files will not be overwritten.

The babun update command will also update the underlying cygwin version if never version is available. In such case babun will download the new cygwin installer, close itself and start the cygwin installation process. Once cygwin installation is completed babun will restart.
