# caveman — installer shim (Windows / PowerShell).
|
|
#
|
|
# Thin wrapper around bin/install.js (the unified Node installer). Every flag
|
|
# you'd pass to bin/install.js can be passed here; we just forward them.
|
|
#
|
|
# One-line install:
|
|
# irm https://raw.githubusercontent.com/JuliusBrussee/caveman/main/install.ps1 | iex
|
|
#
|
|
# Local clone:
|
|
# pwsh install.ps1 [flags]
|
|
#
|
|
# Why a Node installer? install.sh + install.ps1 used to be parallel sources of
|
|
# truth and constantly drifted (issue #249 was a `node -e "..."` quoting bug
|
|
# that silently dropped the JSON merge step on every Windows install). One
|
|
# Node script works everywhere without quoting bugs.
|
|
#
|
|
# Why no top-level param() and everything inside a function? `irm | iex`
|
|
# executes this file as a string: script-path variables ($PSCommandPath,
|
|
# $MyInvocation.MyCommand.Path) are $null and a top-level param block cannot
|
|
# receive arguments through a pipe anyway (issue #565). Wrapping the logic in
|
|
# a function and forwarding $args keeps one script working for both the pipe
|
|
# path (no args, no script path) and the local-clone path.
