# 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. Tries SSH clone (git@gitssh.toomuchtaco.net:taco/dots.git); falls back
|
|
# to HTTPS (https://git.toomuchtaco.net/taco/dots.git) and rewrites the
|
|
# remote origin to SSH so future pushes use the right URL
|
|
# 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, etc.)
|
|
# 5. Warns if SSH key is needed and points to the keyme helper
|
|
# 6. 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
