# This script can be "curl-piped" into bash to bootstrap a dotfiles repo when
|
|
# yadm is not locally installed. Read below for instructions.
|
|
#
|
|
# This script is hosted at bootstrap.yadm.io to make it easy to remember/type.
|
|
#
|
|
# DISCLAIMER: In general, I would advise against piping someone's code directly
|
|
# from the Internet into an interpreter (like Bash). You should
|
|
# probably review any code like this prior to executing it. I leave
|
|
# it to you to decide if this is risky behavior or not. The main
|
|
# reason this script exists is because I find it to be a pragmatic
|
|
# way to bootstrap my dotfiles, and install yadm in one step
|
|
# (allowing the yadm project to be a submodule of my dotfiles
|
|
# repo).
|
|
#
|
|
# Invoke bootstrap with:
|
|
#
|
|
# curl -L bootstrap.yadm.io | bash
|
|
#
|
|
# OR
|
|
#
|
|
# curl -L bootstrap.yadm.io | bash [-s -- REPO_URL [YADM_RELEASE]]
|
|
#
|
|
# Alternatively, source in this file to export a yadm() function which uses
|
|
# yadm remotely until it is locally installed.
|
|
#
|
|
# source <(curl -L bootstrap.yadm.io)
