# ? this script performs the tasks necessary to produce a mostly
# standalone cortav executable from the source files in the
# repository. it assumes the presence of the following tools
# in $SHELL or in $PATH:
#
# * which * cat
# * mkdir * echo
# * install * lua
# * luac * sh
#
# if any are not present, the build will fail, although a missing
# `which` can be worked around by specifying the paths to lua, luac,
# and `sh` directly
#
# to create a truly standalone cortav binary, build the target
# $(build)/cortav.bin - this will wrap the cortav bytecode in a C
# shim and produce a binary executable. depending on your needs,
# you may want to link lua statically or as a shared library.
# to do this, you'll need to set the variable lua-prefix to the
# location of your lua build. if you have lua installed systemwide,
# this will probably be something like `lua-lib-prefix=/usr/lib`,
# or on Nix `lua-lib-prefix=$(nix path-info lua5_3)/lib`. normally
# however if you're building a standalone binary, you probably don't
# have lua installed systemwide, so you'll want to set this to the
# directory where liblua.a is to be found.
#
# note that the standalone build script assumes you're using a
# relatively standard cc, not something like msvc. if your cc
# doesn't accept options like -l -x -o then you'll have to build
# the binary by hand, sorry. but if you want to contribute a build
# script to the repository, i'll happily take merge requests :)
