unclechu’s bash config

Usage

Nix

Try it in a nix-shell

nix-shell --run wenzels-bash

As a NixOS system dependency

{ pkgs, ... }:
let
  wenzels-bash = pkgs.callPackage (pkgs.fetchFromGitHub {
    owner = "unclechu";
    repo = "bashrc";
    rev = "ffffffffffffffffffffffffffffffffffffffff"; # Git commit hash
    sha256 = "0000000000000000000000000000000000000000000000000000";
  }) {};
in
{
  environment.shells         = [ wenzels-bash.wenzels-bash ];
  environment.systemPackages = [ wenzels-bash.wenzels-bash ];
  users.users.john.shell     =   wenzels-bash.wenzels-bash  ;
}

Customizations

See the misc/ directory for setup scripts and aliases. You could use miscSetups and miscAliases Nix attributes to add them to the final configuration. An example:

{ pkgs, lib, ... }:
let
  wenzels-bashrc-src = pkgs.fetchFromGitHub {
    owner = "unclechu";
    repo = "bashrc";
    rev = "ffffffffffffffffffffffffffffffffffffffff"; # Git commit hash
    sha256 = "0000000000000000000000000000000000000000000000000000";
  };

  skim-shell-scripts =
    pkgs.callPackage
      "${wenzels-bashrc-src}/nix/integrations/skim-shell-scripts.nix"
      {};

  wenzels-bash = pkgs.callPackage wenzels-bashrc-src {
    miscSetups = dirEnvVarName: ''
      . "''$${dirEnvVarName}/misc/setups/fuzzy-finder.bash"
      . ${lib.escapeShellArg skim-shell-scripts}/completion.bash
      . ${lib.escapeShellArg skim-shell-scripts}/key-bindings.bash
    '';

    miscAliases = dirEnvVarName: ''
      . "''$${dirEnvVarName}/misc/aliases/skim.bash"
      . "''$${dirEnvVarName}/misc/aliases/fuzzy-finder.bash"
      . "''$${dirEnvVarName}/misc/aliases/tmux.bash"
      . "''$${dirEnvVarName}/misc/aliases/gpg.bash"
    '';
  };
in
{
  environment.shells         = [ wenzels-bash.wenzels-bash ];
  environment.systemPackages = [ wenzels-bash.wenzels-bash ];
  users.users.john.shell     =   wenzels-bash.wenzels-bash  ;
}

Use with my Neovim config

See https://github.com/unclechu/neovimrc

{ pkgs, ... }:
let
  wenzels-neovim-src = pkgs.fetchFromGitHub {
    owner = "unclechu";
    repo = "neovimrc";
    rev = "ffffffffffffffffffffffffffffffffffffffff"; # Git commit hash
    sha256 = "0000000000000000000000000000000000000000000000000000";
  };

  wenzels-neovim =
    pkgs.callPackage "${wenzels-neovim-src}/nix/apps/neovim.nix" {
      bashEnvFile = "${wenzels-bash.dir}/.bash_aliases";
    };

  wenzels-bash = pkgs.callPackage (pkgs.fetchFromGitHub {
    owner = "unclechu";
    repo = "bashrc";
    rev = "ffffffffffffffffffffffffffffffffffffffff"; # Git commit hash
    sha256 = "0000000000000000000000000000000000000000000000000000";
  }) {};
in
{ environment.systemPackages = [ wenzels-bash.wenzels-bash wenzels-neovim ]; }

Also the scripts

nix-shell -E 'with import <nixpkgs> {}; mkShell {buildInputs=[(callPackage nix/scripts/timer.nix {})];}' --run 'timer --help'

nix-shell -E 'with import <nixpkgs> {}; mkShell {buildInputs=[(callPackage nix/scripts/hsc2hs-pipe.nix {})];}' --run 'hsc2hs-pipe --help'

Other GNU/Linux distributions

1. Clone this repo:

   git clone --recursive https://github.com/unclechu/bashrc.git ~/.config/bashrc

2. Create ~/.bashrc with this content:

   if [[ -z $PS1 ]]; then return; fi
   . "$HOME/.config/bashrc/.bashrc"

3. Create ~/.bash_aliases with this content:

   . "$HOME/.config/bashrc/.bash_aliases"

Customizations

See the misc/ directory for setup scripts and aliases. You could just import those scripts from ~/.bashrc and ~/.bash_aliases. Here is an example:

• ~/.bashrc file:

  if [[ -z $PS1 ]]; then return; fi
  . "$HOME/.config/bashrc/.bashrc"
  
  . "$HOME/.config/bashrc/misc/setups/fuzzy-finder.bash"
  . /path/to/skim/shell/completion.bash
  . /path/to/skim/shell/key-bindings.bash

• ~/.bash_aliases file:

  . "$HOME/.config/bashrc/.bash_aliases"
  
  . "$HOME/.config/bashrc/misc/aliases/skim.bash"
  . "$HOME/.config/bashrc/misc/aliases/fuzzy-finder.bash"
  . "$HOME/.config/bashrc/misc/aliases/tmux.bash"
  . "$HOME/.config/bashrc/misc/aliases/gpg.bash"

Known issues

NixOS

In order to prevent loss of the command history this config uses different history file (by default ~/.wenzels_bash_history instead of ~/.bash_history).

If you want vanilla Bash sessions to use that history file don’t just override HISTFILE or you can loose some of your commands history due to smaller history size in Bash defaults. Instead evaluate history-settings.bash in those Bash sessions. It will both override HISTFILE and other command history settings such history size.

You can use Home Manager in order to include history-settings.bash in your ~/.bashrc. Like this in your configuration.nix:

{ pkgs, lib, ... }:
let
  home-manager = fetchTarball {
    # Branch: release-22.05
    # Date: 2022-06-25
    url = "https://github.com/nix-community/home-manager/archive/4a3d01fb53f52ac83194081272795aa4612c2381.tar.gz";
    sha256 = "0sdirpwqk61hnq8lvz4r2j60fxpcpwc8ffmicail2n4h6zifcn9n";
  };

  wenzels-bash = pkgs.callPackage (pkgs.fetchFromGitHub {
    owner = "unclechu";
    repo = "bashrc";
    rev = "ffffffffffffffffffffffffffffffffffffffff"; # Git commit hash
    sha256 = "0000000000000000000000000000000000000000000000000000";
  }) {};
in
{
  imports = [
    (import "${home-manager}/nixos")
  ];

  # … Other stuff in your "configuration.nix" …

  home-manager.users.john.home.file.".bashrc".text = ''
    . ${lib.escapeShellArg wenzels-bash.history-settings-file-path}
  '';
}

Entering nix-shell

When you enter nix-shell is uses its default Bash session. If you want to enter some nix-shell and to keep your current $SHELL you can use --command in order to inherit your $SHELL inside new session:

nix-shell -p hello --command 'export SHELL='"'${SHELL//\'}'"' && "$SHELL"'

In fact this Bash config provides nsh alias in .bash_aliases that does it for you. So just replace nix-shell with nsh and your $SHELL is inherited.
