Cygwin

Cygwin provides a unix-like environment to run processes under windows by emulating unix syscalls.
It has no CLI package manager, but the installer can be scripted to install packages.

Install

chocolatey installs cygwin to C:\programdata\chocolatey\cygwin\tools\cygwin

Cygwin is built to be able to be run in a portable way. You install, update, and get new packages by re-running the cygwin installer.

Always install the 32 bit version of cygwin, unless you absolutely need it to be 64bit. It is much more supported. Cygwin doesn't seem to require any registry keys to be set, the only things that affect it's portability are some environment variables.

NOTE If you are using my package-setup script, always run it with a normal cygwin http-repo as a source, reboot, then run with the private key for a cygports repo. If you fail to do this, and run the cygports repo first, you may end up with corrupted packages.

Package Management

Best Sources
http://lug.mtu.edu		standard cygwin packages
http://mirrors.kernel.org/sources.redhat.com/cygwinports/		precompiled cygports (https://sourceware.org/cygwinports/)

## Start Cygwin with GPG key for cygports
/path/to/setup-x86.exe -K http://cygwinports.org/ports.gpg

CYGPORTS CONTAINS DWM, MPD, NCMPC, PYSIDE
Cygwin doesn't have a traditional package manager. There are a few terminal programs you can use to emulate apt-get, but since on Windows files cannot be deleted or overwritten while they are running it is best to quit cygwin, and install programs using the installer.

Because of cygwin's limited options in the default repo, I find myself compiling packages myself quite a lot. I created a git repo for compiled (and attempts at compiling) programs for quick (manual) installations on new machines.

There is also a system loosely based on Gentoo's portage to assist in compilation. It is called cygports, and can be installed from the main package manager.

Common Problems

rebase

Almost all issues related to cygwin can be resolved by rebasing. You can do it the quick/dirty way:

C:/cygwin/bin/dash.exe
/bin/rebaseall

Or the full proper way:

- Open Task Manager and close any processes that look to be Cygwin related.
- Open C:\Cygwin\bin in Windows Explorer
   - Verify that dash.exe, ash.exe, rebase.exe, and rebaseall exist in this folder
      - If any of them are missing, re-run Cygwin setup and select the dash, ash, and rebase packages

    - right-click your C:\Cygwin folder, uncheck Read-only (if its checked), and press OK.
      - When an error about not being able to switch some files comes up, select "Ignore All". Wait for this process to complete.

    - Browse to C:\Cygwin\bin in Windows Explorer
    - Right click dash.exe and click "Run as Administrator". A command Prompt should appear with nothing but a $
    - Type /usr/bin/rebaseall -v, hit enter, and wait for the process to complete.
        - If you get errors about Cygwin processes running, try Step 1 again. If that still doesn't work, Restart your computer into safe mode and try these steps again.
        - A commenter noted that, depending on your settings, you may have to type cd /usr/bin && ./rebaseall -v instead.
    - Try opening Cygwin again.

Programs

Cygwin does not by default include a CLI package manager. Instead, you run cygwin.exe with the flag 'config', which updates your existing cygwin (labeled as installation, but only checks for missing/out of date files). I have included the option of running 'CygwinPers.bat --config'. There are package managers available for cygwin, such as apt-cyg, but they're pretty awful. It is much better to just use the default installer.

Base Packages:

	mutt
	w3m
	ncurses
	abook
	xclip
	git, git-completion, gitk, tig

Terminal Programs

mintty

openssh

mutt

mpd

X Programs

Xserver

WINAPI

I'm not entirely sure what this is, or how it works but this is how DWM is able to run natively in windows, and manage win32 windows ( but not cygwin windows unless launched with startxwin /usr/bin/<progrm> )

Fonts

/usr/share/fonts/font.ttf	font dir
fc-list	list all fonts

There is not a lot of options for fonts in the cygwin package repo, Here are the fonts that I use most frequently:

## Droid-Sans-Mono (preference)
http://www.fontsquirrel.com/fonts/droid-sans-mono

## DejaVu
http://sourceforge.net/projects/dejavu/

## copy fonts to /usr/share/fonts/
fc-list											##List all currently available fonts
Urxvt.font:	xft:Droid Sans Mono-10		##Setting font for urxvt in ~/.Xdefaults

feh

feh is an awesome image viewer. requires imlib2

## CYGWIN DEPENDENCIES:
# imlib2, libcurl, libcurl-devel, libpng, libX11, libXinerama, libXt-devel
# make sure to install all imlib, imlib2, libiml, and devel packages from setup.exe
#
# note that when hunting down a package because of a compile error, you can use
# cygcheck for more info ex: cygcheck -p x11/Intrinsic.h

curl -#O http://feh.finalrewind.org/feh-2.12.tar.bz2
make
make install
cp feh.exe /usr/bin/
