# FIXME: Using luamake from source tree instead of system package
#
# Normally, we would declare luamake as a build dependency:
#   depends_build    port:luamake
#   build.cmd       ${prefix}/bin/luamake rebuild
#
# However, the lua-language-server project uses a specific, unversioned
# development snapshot of luamake bundled in its 3rd/ directory.
# The system-installed luamake package (which is versioned) is incompatible
# with the build system expectations.

notes "
    To use in Neovim, it is sufficient to specify cmd in lspconfig:

        require'lspconfig'.lua_ls.setup \{
            cmd = \{\"${prefix}/bin/${name}\"\};
        \}

    See more https://github.com/neovim/nvim-lspconfig/blob/master/doc/server_configurations.md#sumneko_lua
