** Dependencies

- [[https://helm.sh/][Helm]] (obviously)

- (GNU) awk

- [[https://yq.readthedocs.io/][yq]]

- Optional (for ~make install~): [[https://www.gnu.org/software/stow/][GNU Stow]]

** Script

   :PROPERTIES:

   :header-args: :tangle outdated.sh

   :END:

Be safer.

#+BEGIN_SRC sh :shebang "#! /usr/bin/env bash"

set -euo pipefail

#+END_SRC

Iterate through each dependency, and determine if it's outdated.

#+BEGIN_SRC sh

while IFS= read -r dependency; do

    subchart="${dependency%-*}"

    current="${dependency##*-}"

    latest=$(helm inspect chart "$subchart" | yq -r '.version')

    if [ "$current" == "$latest" ]; then

        printf "%s is up to date.\\n" "$subchart"

    else

        printf "Consider upgrading %s: %s -> %s.\\n" \

            "$subchart" "$current" "$latest"

    fi

done < <(helm dep list \

    | grep -v WARNING \

    | tail -n+2 | head -n-1 | sort -u \

    | awk '{ sub("@","",$3); printf "%s/%s-%s\n", $3, $1, $2; }')

** Installation

   :PROPERTIES:

   :header-args: :tangle Makefile :padline no

   :END:

The default target, =install=, is phony.

#+BEGIN_SRC makefile

.DEFAULT: install

.PHONY: install

#+END_SRC

The =install= target tangles [[./README.org][README.org]], creates the target directory if

missing, and uses [[https://www.gnu.org/software/stow/][GNU Stow]] to install the plugin.

#+BEGIN_SRC makefile

install: README.org

	@ emacs --batch --quick \

		--load ob-tangle \

		--eval '(setq org-src-preserve-indentation t)' \

		--eval '(org-babel-tangle-file "$<")'

	@ mkdir -p "$${HELM_HOME:-$$HOME/.helm}/plugins/outdated"

	@ stow -t "$${HELM_HOME:-$$HOME/.helm}/plugins/outdated" .
