dotfiles

(Outdated: I use micromamba now, and keep my softwares in an environment named sw, not touching base.)

Steps to terraform a new machine, mostly for personal reference:

1. Change to home directory:

   cd ~

2. Install dotfiles:

   git clone https://github.com/rishabh-ranjan/dotfiles
   cp -r dotfiles/* dotfiles/.* .

   Errors like these are acceptable:

   cp: '/home/rishabhr/dotfiles/..' and '/home/rishabhr' are the same file
   cp: cannot create regular file '/home/rishabhr/.git/objects/pack/pack-c20af10d644dc847dce7d997b0fbaedcfaf40108.pack': Permission denied
   cp: cannot create regular file '/home/rishabhr/.git/objects/pack/pack-c20af10d644dc847dce7d997b0fbaedcfaf40108.idx': Permission denied
   

3. Install mambaforge:

   aria2c https://github.com/conda-forge/miniforge/releases/latest/download/Mambaforge-Linux-x86_64.sh # for linux
   chmod +x Mambaforge-Linux-x86_64.sh
   echo -e "\nyes\n~/.mambaforge\nno" | ./Mambaforge-Linux-x86_64.sh

   Use 'q' to exit the license.

4. Update the mamba base environment:

   mamba env update -f ~/.config/mamba/base.yml --prune

5. At this point, we can ssh into the machine again. As per the message, setup prompt:

   fisher install IlanCosman/tide@v5
   echo 1 1 3 2 2 1 1 1 y | tide configure > /dev/null

   Select n in Configure tide prompt? [Y/n]. The second line will configure prompt automatically.

   Login again for the prompt to take effect.

6. Install neovim from the Releases page https://github.com/neovim/neovim/releases. [TODO: detailed commands]

7. Clean up home directory:

   rm -rf .bash_history .bash_logout .bashrc .cache .conda dotfiles Mambaforge-Linux-x86_64.sh
   ls -a

8. Add ssh-key with:

   ssh-copy-id <username>@<hostname>

9. If required, add a custom rc for fish at ~/.config/fish/custom/<name>.fish and link to it (or one of the existing ones) with:

   ln -s ~/.config/fish/custom/<name>.fish ~/.config/fish/custom.fish

10. Neovim should install plugins and do other setup automatically on first run:

    nvim

    Might give error on the first run because plug.vim is not recognized yet, but simply quitting and rerunning nvim fixes this.

11. Github login:

    BROWSER=false gh auth login

    Sometimes upgrading gh causes trouble. In that case, simply delete the gh auth lines from ~/.gitconfig.

12. Update home directory permissions:

    chmod 750 ~

    This gives you read-write-execute, group users read-execute, and other users no permissions.
