# install.fish — Dotfiles bootstrap script
|
||||
# =============================================================================
|
||||
#
|
||||
# Quick install (copy-paste this one-liner):
|
||||
#
|
||||
# curl -fsSL https://git.toomuchtaco.net/taco/dots/raw/branch/main/install.fish | fish
|
||||
#
|
||||
# What this script does:
|
||||
# 1. Checks prerequisites: Fish shell, Git, and a few common tools
|
||||
# 2. Clones the dotfiles repository (default: git@gitssh.toomuchtaco.net:taco/dots.git)
|
||||
# 3. Replaces or updates ~/.config/fish/ with the contents of the repo
|
||||
# 4. Sources the new config and runs `dotfiles init` to install templates
|
||||
# (~/.tmux.conf, ~/.gitconfig, ~/.config/starship.toml, etc.)
|
||||
# 5. Prints next steps
|
||||
#
|
||||
# You can pass a custom repo URL as the first argument:
|
||||
#
|
||||
# curl -fsSL https://git.toomuchtaco.net/taco/dots/raw/branch/main/install.fish | fish -s -- https://github.com/you/dotfiles
