+#!/bin/sh
+#
+# This script is used to derive compiler flags and filesystem paths
+# necessary to utilize Lua, LuaJIT, and particular versions thereof in both
+# simple and mixed installation environments.
+#
+# For usage help information use the -h switch.
+#
+# This script attempts to adhere strictly to POSIX shell specifications. The
+# known non-POSIX features used are the path of the shell at the very first
+# line of this script, the default compiler command name of `cc' instead of
+# `c99', and the use of /dev/urandom for generating a random sandbox
+# directory suffix. All of these can be override. For any other issues
+# please contact the author.
+#
+# WARNING: When searching for a Lua interpreter this script may execute
+# various utilities in an attempt to deduce their fitness and release
+# version. By default this script will search for and execute utilities
+# using the glob patterns luac* and lua*. But this script CANNOT GUARANTEE
+# that executing such utilities, or any other utilities, either wittingly or
+# unwittingly, will not result in your COMPUTER EXPLODING. You have been
+# warned.
+#
+# # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # #
+#
+# Changelog:
+#
+# * 2013-08-02 - Published. Derived from an earlier script, lua.path,
+# written for the cqueues project.
+#
+# * 2013-08-05 - Redirect stdin from /dev/null when probing so we don't
+# freeze if a utility tries to read from stdin.
+#
+# chdir to a read-only directory by default to try to prevent creation
+# of temporary files. These features address the issues of LuaTeX
+# reading from stdin and creating a luatex.out file in the current
+# working directory. By default a directory with a random suffix
+# generated from /dev/urandom is placed in TMPDIR and removed on exit.
+#
+# If CPPFLAGS is empty and no -I options directly specified then set
+# INCDIRS to "/usr/include:/usr/local/include".
+#
+# * 2013-08-07 - Add pkg-config support and refactor header probing to delay
+# recursive searching.
+#
+# * 2013-09-09 - NetBSD's sh gets upset over the noclobber option and
+# redirection to /dev/null, so use append operator. And check $#
+# before iterating over a null parameter set with `do X; ... done`
+# when `set -u` is enabled--it complains about $@ being unset.
+#
+# * 2013-10-22 - Initial ldflags detection.
+#
+# * 2014-01-26 - Migrate CC vendor detection from external script.
+#
+# * 2014-09-29 - Add ldir and cdir modes which print install path by parsing
+# package.path and package.cpath.
+#
+# * 2014-12-18 - Add -e GLOB option.
+#
+# Deprecate ldir and cdir modes.
+#
+# Add package.path and package.cpath to replace ldir and dir modes.
+# Optional arguments to the new modes are preferred install paths,
+# rather than globs for finding the lua utility path (use the new -e
+# option, instead).
+#
+# * 2014-12-19 - Fix pkg-config version matching. The --modversion of
+# the lua package might be stale. For example, it's 5.2.0 on Ubuntu
+# 14.04 even though the Lua release is 5.2.3.
+#
+# Use the interpreter path as a reference point when searching for
+# headers. $(dirname ${LUA_PATH})/../include is a very likely location
+# as bindir and includedir have the same prefix in most installations.
+#
+# * 2015-01-15 - Quote more command names and arguments. Still need to
+# handle space characters in code that employs command substitution. I
+# think we could handle all whitespace characters, including newlines,
+# by using a control character in IFS and using --exec printf "%s\1" {}
+# rather than -print with find(1).
+#
+# * 2015-01-19 - Add fix for LuaJIT's default package.cpath, which tends to
+# hardcode /usr/local/lib/lua/5.1, ordered before the LuaJIT
+# installation prefix.
+#
+# * 2015-07-14 - Add recursive glob function implemented in shell code
+# and use instead of find(1).
+#
+# * 2016-03-18 - Fix bug in tryluac where a continue statement was used
+# instead of return 0.
+#
+# * 2016-03-25 - Support ${CC} values with trailing flags, which invoke
+# the compiler through env(1), or which otherwise are intended to
+# expand as multiple words.
+#
+# OpenBSD 5.8 sh does not suppress strict errors within an eval
+# invoked from an if condition compound-list. Workaround by changing
+# trylua to return 0 on matching failure, like tryluainclude and
+# tryluac do.
+#
+# Undeprecate ldir and cdir. The names are more intuitive and
+# convenient as evidenced by the fact that I keep using them instead
+# of package.path and package.cpath. Try to maintain backwards
+# compatibility by using a simple heuristic to differentiate lua
+# interpreter glob patterns from preferred install directory
+# string.match expressions.
+#
+# * 2016-10-10 - Fix issue with passing empty CPPFLAGS to ${CC}. /usr/bin/cc
+# in NetBSD 7.0.1 does not tolerate an empty string argument. This
+# exposed a bug in NetBSD's and FreeBSD's /bin/sh, triggered by how we
+# pass CPPFLAGS (see evalmacro and runcc routines, below).
+#
+# Some Ash variants (confirmed /bin/sh in NetBSD 7.0.1 and FreeBSD
+# 10.1) will expand unquoted ${UNSET-} and ${UNSET:-} as an empty
+# string rather than eliding it during argument processing. That is,
+#
+# nargs() { printf "%d\n" "$#"; }
+# nargs ${UNSET} 2 3
+# nargs ${UNSET-} 2 3
+#
+# prints "2" and "3", whereas every other shell tested prints "2" and
+# "2" (confirmed dash in Ubuntu Xenial; bash 4.3 in Ubuntu Xenial;
+# pdksh in FreeBSD 10.1, NetBSD 7.0, OS X 10.1, OpenBSD 6.0; ksh93 in
+# Solaris 11.3 and AIX 7.1; ksh88 in AIX 7.1).
+#
+# A workaround in set -u mode (where unbound variable expansion aborts
+# execution) is to substitute a known empty value. E.g.
+#
+# EMPTY=
+# nargs ${UNSET-$EMPTY}

+ This utility is used to derive compiler flags and filesystem paths
+ necessary to utilize Lua, LuaJIT, and particular versions thereof.
+ On success it prints the requested information and exits with 0,
+ otherwise it fails with an exit status of 1.
+
+ Note that cppflags may not print anything if no additional flags are
+ required to compile against the requested API version.
+
+ When searching, the highest Lua version is preferred. Searching
+ stops once the highest version in the allowable range is found
+ unless the -s flag is specified.
+
+ LuaJIT is treated like any other Lua installation. If an explicit
+ LuaJIT version or range is specified, then only LuaJIT installations
+ will match. To exclude LuaJIT entirely use the -J switch.
+
+ This utility processes the environment variables CC, CPPFLAGS,
+ LDFLAGS, and PATH if present. If recursion is requested, then
+ directories specified in CPPFLAGS, LDFLAGS, and PATH are also
+ recursed.
+
+ If the environment variable CPPFLAGS is empty and no -I options are
+ specified directly, then /usr/include and /usr/local/include are
+ used when probing for cppflags and API version.
