Arch Linux hints

Arch Linux has nothing to do with Huskell but as a matter of fact, it is the platform on which I am suppose to learn programming Haskell. That's why I have Arch Linux running as a Docker container on my Mac.

Docker commands

Fire up docker container and open an interactive (-i) terminal (-t) with a bash shell.

docker run -it --privileged=true archlinux:latest bash

Packman

The package manager pacman

example: Install nano

pacman -Syu nano

Operations:

S - Sync with database

Options:

y - refresh
u - upgrade installed packages

Operations help:

# show operations
$ packman --help

usage:  pacman <operation> [...]
operations:
    pacman {-h --help}
    pacman {-V --version}
    pacman {-D --database} <options> <package(s)>
    pacman {-F --files}    [options] [package(s)]
    pacman {-Q --query}    [options] [package(s)]
    pacman {-R --remove}   [options] <package(s)>
    pacman {-S --sync}     [options] [package(s)]
    pacman {-T --deptest}  [options] [package(s)]
    pacman {-U --upgrade}  [options] <file(s)>

# show options on Sync
$ packmann -S --help

usage:  pacman {-S --sync} [options] [package(s)]
options:
members)
  -i, --info           view package information (-ii for extended information)
  -l, --list <repo>    view a list of packages in a repo
  -q, --quiet          show less information for query and search
  -s, --search <regex> search remote repositories for matching strings
  -u, --sysupgrade     upgrade installed packages (-uu enables downgrades)
  -y, --refresh        download fresh package databases from the server
...

Install the most basic packets

pacman -Syu vi sudo

Configure groups and user

# configure sudo and un-comment the wheels group
sudo visudo
# %wheel ALL=(ALL) ALL

# use useradd to also generate a home dir
useradd -G wheel -m <username> -p <password>

# change to new user
su - <username>

Install Haskell

Wiki about Haskell on Arch Linux

Install the Glasgow Haskell Compiler ghc

sudo pacman -Syu ghc

Done. That's it if you use the console only. Else checkout the Arch Linux Wiki about Visual Studio Code
