# Verifies that each package the Makefile stows actually resolves and that
|
|
# stow can create all symlinks into the target without conflicts.
|
|
#
|
|
# This is a DRY RUN: it uses `stow --simulate` and creates no real symlinks.
|
|
# It catches bugs like `stow nvim` for a non-existent `nvim/` package.
|
|
#
|
|
# Usage:
|
|
# bash test/probe_stow.sh # probe every stow-able package
|
|
# bash test/probe_stow.sh <pkg>... # probe specific packages
|
