                Cleaning haskell packages from pacman
              
          
    Cleaning up haskell packages on Arch Linux

In Arch Linux, all haskell packages are dynamically linked. This can be a headache for the user, since it results in a large amount of haskell-* packages being installed on your system, and the possibility for version conflicts. A way around this is to not depend on pacman at all for haskell packages, but manually install them.
In this document I explain how I switched from a lot of haskell packages installed with pacman, to a few manually installed packages.
Finding packages to uninstall

To determine which packages to uninstall (and replace), a few tools are useful:

pacman itself
pacgraph

    Hexadecimal color code for transparency


How to set transparency with hex value ?

For example, you want to set 40% alpha transparence to #000000 (black color), you need to add 66 like this #66000000.
All hex value from 100% to 0% alpha:

MinGW doesn't provide a linux-like environment, that is MSYS(2) and/or Cygwin

Cygwin is an attempt to create a complete UNIX/POSIX environment on Windows.
MinGW is a C/C++ compiler suite which allows you to create Windows executables - you only
need the normal MSVC runtimes, which are part of any normal Microsoft Windows installation.

MinGW provides headers and libraries so that GCC (a compiler suite,
not just a "unix/linux compiler") can be built and used against the Windows C runtime.
