# $NetBSD: modules.mk,v 1.26 2019/06/08 10:40:54 rillig Exp $
#
# This Makefile fragment handles Emacs Lisp Packages (== ELPs).
#
# Note to users:
#
# * Users choose one favourite Emacs version.
#
# * Emacs Lisp files are installed...
# GNU emacs
# -> ${PREFIX}/share/emacs/site-lisp/foo/...
# XEmacs
# ->${PREFIX}/lib/xemacs/site-packages/lisp/foo/...
#
# * You can't install an ELP for both Emacs and XEmacs
# simultaneously.
#
# * XEmacs package's names are prefix'ed by "xemacs-".
#
# Note to package developers:
#
# * XEmacs package's names are prefix'ed by "xemacs-".
#
# This is to make sure ELPs for XEmacs keep their own dependency
# tree (for example, if an ELP "bar" depends on another ELP "foo",
# "xemacs-bar" depends on "xemacs-foo". "foo" (installed for GNU
# Emacs) is useless for "xemacs-bar" in this case.).
#
# Make sure too that "foo" and "xemacs-foo" conflict each other,
# since they can share some files. (Making all ELPs separately
# installable for GNU Emacs/XEmacs might be possible.)
#
# * Assume each ELP supports all Emacs versions by default. If the
# ELP supports only certain Emacs versions, define EMACS_VERSIONS
# _ACCEPTED explicitly before including mk/emacs.mk.
#
# Variables for users:
#
# EMACS_TYPE
# Description:
# The user's favourite Emacs version. The default
# value is set in mk/defaults/mk.conf.
# Possible values:
# emacs26, emacs26nox, emacs25, emacs25nox, emacs21,
# emacs21nox, emacs20, xemacs215, xemacs215nox,
# xemacs214, xemacs214nox
# Default value:
# emacs26
#
# Variables ELPs can provide:
#
# EMACS_MODULES
# Description:
# List of Emacs LISP modules that the current ELP
# needs at run-time.
# Possible values:
# base, leim
# Default value:
# <undefined>
#
# EMACS_VERSIONS_ACCEPTED
# Description:
# Versions the ELP accepts (supports).
# Possible values:
# emacs26, emacs26nox, emacs25, emacs25nox, emacs21,
# emacs21nox, emacs20, xemacs215, xemacs215nox,
# xemacs214, xemacs214nox
# Default value:
# emacs26, emacs26nox, emacs25, emacs25nox, emacs21,
# emacs21nox, emacs20, xemacs215, xemacs215nox,
# xemacs214, xemacs214nox
#
# EMACS_BUILDLINK
# Description:
# Whether create buildlink directory of *.el / *.elc
# files. ELPs which include other ELP's buildlink3.mk
# must define this value.
# Possible values:
# <defined>, <undefined>
# Default value:
# <undefined>
#
# Variables provided for ELPs:
#
# EMACS_BIN
# Description:
# Path to Emacs executable.
# Possible values:
# ${PREFIX}/bin/emacs, ${PREFIX}/bin/xemacs
#
# EMACS_ETCPREFIX
# Description:
# Path to the directory misc. files should be
# installed into. ELPs should append a short
# name as a subdirectory.
# Possible values:
# ${PREFIX}/share
# ${PREFIX}/lib/xemacs/site-packages/etc
#
# EMACS_FLAVOR
# Description:
# GNU Emacs (emacs) or XEmacs (xemacs).
# Possible values:
# emacs, xemacs
#
# EMACS_INFOPREFIX
# Description:
# Path to the directory Info files should be
# installed into. Unlike EMACS_ETCPREFIX or
# EMACS_LISPPREFIX, subdirectory is not needed.
# Possible values:
# ${PREFIX}/${PKGINFODIR}
# ${PREFIX}/lib/xemacs/site-packages/info
#
# EMACS_LISPPREFIX
# Description:
# installed into. ELPs should append a short name
# as a subdirectory.
# Possible values:
# ${PREFIX}/share/emacs/site-lisp
# ${PREFIX}/lib/xemacs/site-packages/lisp
#
# EMACS_PKGNAME_PREFIX
# Description:
# The prefix of PKGNAME and DEPENDS lines. All ELPs
# must honour this!
# Possible values:
# "", "xemacs-"
#
# EMACS_VERSION_MAJOR
# Description:
# Emacs major version.
# Possible values:
# 20, 21, 25, 26, <integers more than that in the future>
#
# EMACS_VERSION_MINOR
# Description:
# Emacs minor version.
# Possible values:
# <integer>
#
# EMACS_VERSION_MICRO
# Description:
# Emacs micro version.
# Possible values:
# <integer>
#
# Variables provided in ELPs' PLIST:
#
# EMACS_ETCPREFIX
# Description:
# Same as the one in Makefile, except that
# ${PREFIX} is omitted in PLIST.
# Possible values:
# share
# lib/xemacs/site-packages/etc
#
# EMACS_INFOPREFIX
# Description:
# Same as the one in Makefile, except that
# ${PREFIX} is omitted in PLIST.
# Possible values:
# ${PKGINFODIR}
# lib/xemacs/site-packages/info
#
# EMACS_LISPPREFIX
# Description:
# Same as the one in Makefile, except that
# ${PREFIX} is omitted in PLIST.
# Possible values:
# share/emacs/site-lisp
# lib/xemacs/site-packages/lisp
#
# EMACS_VERSION
# Description:
# XXX
# Possible values:
# XXX
#
# FOR_{emacs26,emacs26nox,emacs25,emacs25nox,emacs21,emacs21nox,emacs20,xemacs215,xemacs215nox,xemacs214,xemacs214nox}

# NOTFOR_{emacs,xemacs}
# NOTFOR_{emacs_x,emacs_nox}
# Description:
# These macros will become either an empty string or
# "@comment" depending on the Emacs version; when
# "emacs21" is used, ${FOR_emacs} and ${FOR_emacs21}
# become "" (empty), and other macros become
# "@comment"; this means that only the PLIST lines
# prefixed by ${FOR_emacs} and ${FOR_emacs21} are
# valid.
#
# NOTFOR_* is the opposite of FOR_*.
# Possible values:
# "", "@comment"
#
# FOR_emacs_no_byte_compile
