# * makem.sh --- Script to aid building and testing Emacs Lisp packages
# https://github.com/alphapapa/makem.sh
# * Commentary:
# makem.sh is a script helps to build, lint, and test Emacs Lisp
# packages. It aims to make linting and testing as simple as possible
# without requiring per-package configuration.
# It works similarly to a Makefile in that "rules" are called to
# perform actions such as byte-compiling, linting, testing, etc.
# Source and test files are discovered automatically from the
# project's Git repo, and package dependencies within them are parsed
# automatically.
# Output is simple: by default, there is no output unless errors
# occur. With increasing verbosity levels, more detail gives positive
# feedback. Output is colored by default to make reading easy.
# The script can run Emacs with the developer's local Emacs
# configuration, or with a clean, "sandbox" configuration that can be
# optionally removed afterward. This is especially helpful when
# upstream dependencies may have released new versions that differ
# from those installed in the developer's personal configuration.

$0 [OPTIONS] RULES...
Linter- and test-specific rules will error when their linters or tests
are not found. With -vv, rules that run multiple rules will show a
message for unavailable linters or tests.
Rules:
all Run all lints and tests.
compile Byte-compile source files.
lint Run all linters, ignoring unavailable ones.
lint-checkdoc Run checkdoc.
lint-compile Byte-compile source files with warnings as errors.
lint-declare Run check-declare.
lint-elsa Run Elsa (not included in "lint" rule).
lint-indent Lint indentation.
lint-package Run package-lint.
lint-regexps Run relint.
test, tests Run all tests, ignoring missing test types.
test-buttercup Run Buttercup tests.
test-ert Run ERT tests.
test-ert-interactive Run ERT tests interactively.
batch Run Emacs in batch mode, loading project source and test files
automatically, with remaining args (after "--") passed to Emacs.
interactive Run Emacs interactively, loading project source and test files
automatically, with remaining args (after "--") passed to Emacs.
Options:
-d, --debug Print debug info.
-h, --help I need somebody!
-v, --verbose Increase verbosity, up to -vv.
--debug-load-path Print load-path from inside Emacs.
-E, --emacs PATH Run Emacs at PATH.
-e, --exclude FILE Exclude FILE from linting and testing.
-f, --file FILE Check FILE in addition to discovered files.
--no-color Disable color output.
-C, --no-compile Don't compile files automatically.
Sandbox options:
-s[DIR], --sandbox[=DIR] Run Emacs with an empty config in a sandbox DIR.
If DIR does not exist, make it. If DIR is not
specified, use a temporary sandbox directory and
delete it afterward, implying --install-deps and
--install-linters.
--install-deps Automatically install package dependencies.
--install-linters Automatically install linters.
-i, --install PACKAGE Install PACKAGE before running rules.
An Emacs version-specific subdirectory is automatically made inside
the sandbox, allowing testing with multiple Emacs versions. When
specifying a sandbox directory, use options --install-deps and
--install-linters on first-run and omit them afterward to save time.
Source files are automatically discovered from git, or may be
specified with options. Package dependencies are discovered from
"Package-Requires" headers in source files, from -pkg.el files, and
from a Cask file.

# TODO: Using the current directory (i.e. a package's repo root directory) in
# load-path can cause weird errors in case of--you guessed it--stale .ELC files,
# the zombie problem that just won't die. It's incredible how many different ways
# this problem presents itself. In this latest example, an old .ELC file, for a
# .EL file that had since been renamed, was present on my local system, which meant
# that an example .EL file that hadn't been updated was able to "require" that .ELC
# file's feature without error. But on another system (in this case, trying to
# setup CI using GitHub Actions), the old .ELC was not present, so the example .EL
# file was not able to load the feature, which caused a byte-compilation error.
# In this case, I will prevent such example files from being compiled. But in
# general, this can cause weird problems that are tedious to debug. I guess
# the best way to fix it would be to actually install the repo's code as a
# package into the sandbox, but doing that would require additional tooling,
# pulling in something like Quelpa or package-build--and if the default recipe
# weren't being used, the actual recipe would have to be fetched off MELPA or
# something, which seems like getting too smart for our own good.
# TODO: Emit a warning if .ELC files that don't match any .EL files are detected.
