ctablestack
Catcode table stable support
$ luarocks install --server=https://luarocks.org/dev ctablestackThis package provides a method for defining category code table stacks in LuaTeX. It builds on code provided by the 2015/10/01 release of LaTeX2ε (also available as ltluatex.sty for plain users). It is required by the luatexbase package (v1.0 onward) which uses ctablestack to provide a back-compatibility form of this concept.
