dotfiles

This repo is for setting up my general dotfiles and vim config for Mac and CentOS. The first time setup can be automated with:

$ bash <(curl -s https://raw.githubusercontent.com/mlaursen/dotfiles/master/init.sh)

Note: Check out Methods of Signing with GPG

WSL GPG Setup

• Install Terminal Preview from the App Store
  • This might not be required the next time I have to setup WSL. At the time of writing this, the Terminal Preview allows for custom fonts and colors which is required for me
• Install Ubuntu from the App Store
• Setup the Ubuntu VM with user and stuffs
• Create a new GPG
• Export the GPG key: gpg --armor --export-secret-keys UUID_OF_GPG_KEY > private.cert
• Copy the private.cert to Windows Download folder by navigating to \\wsl$\Ubuntu\home\mlaursen
• https://www.gpg4win.org/
• download + install (can uncheck everything except the required one and Kleopatra)
• Import the private.cert in Kleopatra
• Once imported, certify the cert.
• Increase Passphrase duration to 8 hours:
  • Ctrl+Shift+, -> GnuPG System -> Private Keys -> Update all caches to 28800
• Back in Ubuntu VM, edit ~/.gnupg/gpg-agent.conf to include pinentry-program "/mnt/c/Program Files (x86)/GnuPG/bin/pinentry-basic.exe"
• gpg-connect-agent reloadagent /bye
• this should allow the new gui to handle the passphrase for GPG

WSL Cypress Setup

Reference: https://wilcovanes.ch/articles/setting-up-the-cypress-gui-in-wsl2-ubuntu-for-windows-10/

• install VcXsrv Windows X Server

• update .zshrc to include

  # set DISPLAY variable to the IP automatically assigned to WSL2
  export DISPLAY=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2; exit;}'):0.0
  
  # might need this as well to start dbus daemon
  # sudo /etc/init.d/dbus start &> /dev/null

• start X Server (xLaunch)

  • use default options for display settings
  • disable access control in client startup settings
  • allow both private and public networks when the Windows security popup appears

Useful things

Find all unique occurrences with grep

grep -r --only-matching -h -E '{{REGEX}}' {{DIRECTORY}} | sort --unique

Example:

grep -r --only-matching -h -E '<([A-z]+Icon).* />' "react-md/packages/*/src" | sort unique

CentOS Setup

I can never remember how this goes, so I decided to document this process. Mac is a bit easier since I can just use homebrew for everything, but CentOS/*nix is a bit more difficult since it's something I have to do manually.

Download an ISO

Download an ISO from the CentOS download page and start up a VM using this ISO. Go through the installation process making sure to:

• update the Network configuration to auto-connect to eth0 so that I don't need to manually reconnect each time the VM is resumed.
• update the Network Preferences to be the current timezone and use network to determine
• choose the GNOME Desktop installation and don't check any other feature

Creating an Admin User

Since this is normally a private VM, I can just keep the root password and my mlaursen user's password empty and ensure that mlaursen is an administrator.

If I want to be more secure, I can add a password to both but I'll just need to make sure to login and update mlaursen to be able to use sudo without the password each time with:

$ sudo visudo

 ## Same thing without a password
 # %wheel        ALL=(ALL)       NOPASSWD: ALL
+mlaursen        ALL=(ALL)       NOPASSWD: ALL

Setting up the dev environment

First thing is update packages and install git:

# the git in centos 7 is 1.8.x and crashes for minpac...
$ sudo yum remove git*
$ sudo yum -y install https://centos7.iuscommunity.org/ius-release.rpm
$ sudo yum -y install git2u-all

$ sudo yum update -y
$ sudo yum install \
    the_silver_searcher \
    gcc \
    gcc-c++ \
    cmake \
    ncurses \
    ncurses-devel \
    ruby \
    ruby-devel \
    lua \
    lua-devel \
    ctags \
    python \
    python-devel \
    python3 \
    python3-devel \
    tcl-devel \
    perl \
    perl-devel \
    perl-ExtUtils-ParseXS \
    perl-ExtUtils-CBuilder \
    perl-ExtUtils-Embed \
    -y

Next install chrome:

$ wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
$ sudo yum install google-chrome-stable_current_x86_64.rpm

Finally, the init.sh should be able to take care of the rest.
