/melpazoid/ is a bundle of scripts for testing Emacs packages, primarily
submissions to [[https://github.com/melpa/][MELPA]]. I've been using a variation of this script to help me
check MELPA [[https://github.com/melpa/melpa/pulls][pull requests]]. The ambition is CI checks that run in an "clean"
environment, either through CI or through a container on your local machine.

This is a work in progress -- feedback and pull requests are welcome (note my
current aim is to make this code simpler before I make it any more complicated).

The checks are a combination of:
1. byte-compile-file
2. [[https://www.emacswiki.org/emacs/CheckDoc][checkdoc]]
3. [[https://github.com/purcell/package-lint][package-lint]]
4. a license checker
5. some elisp checks

The first four are on the MELPA checklist, so you should try to get those right.
The license checker is currently very crude. The elisp checks are not foolproof,
sometimes opinionated, and may raise false positives.

* How to use melpazoid
  You can fork it and let CI do the work, or use it locally.
** Fork it and let CI do the work
   If you don't want to install this software or its dependencies, you are
   encouraged to fork this repository and let CI do the work. You will need a
   bit of experience with GitHub.

   Then enable [[https://travis-ci.org][Travis-CI]] on your fork, or just open a pull request against this
   repository (I won't merge it). The eventual build information will report any
   issues.

   Your fork will need to point to the Emacs package you want to build, which
   can be done by modifying the ~.travis.yml~ file in one of the following ways.
*** Test a recipe before you even open a pull request to MELPA
    Modify the ~env~ field and specify your clone url and your recipe:
    #+begin_src yaml
    env: >-
      CLONE_URL='https://github.com/me/my-package-repo
      RECIPE='(my-package :repo "me/my-package-repo" :fetcher github)'
    #+end_src
*** Test a MELPA pull request you've already opened
    Modify the ~env~ field and specify your open MELPA PR:
    #+begin_src yaml
    env: >-
      MELPA_PR_URL='https://github.com/melpa/melpa/pulls/6713
    #+end_src
** Use it locally
   You will need Python ≥ 3.6 (and the ~requests~ package) and Docker. A
   container will be built with (hopefully) all of your requirements installed.
   The output scroll will report any discovered issues.

*** Test a MELPA PR
    #+begin_src bash
    MELPA_PR_URL='https://github.com/melpa/melpa/pull/6718' make
    #+end_src
*** Test a remote package
    #+begin_src bash
    CLONE_URL='https://github.com/riscy/shx-for-emacs' \
        RECIPE='(shx :repo "riscy/shx-for-emacs" :fetcher github)' \
        make
    #+end_src
*** Test a local package (work in progress)
    #+begin_src bash
    PKG_PATH='/path/to/package' \
        PKG_NAME='package-name' \
        make
    #+end_src
