Re: LuaRocks can't find libz.so or libz.dll when installing lzlib

[Patrick Rapin <toupie300@...>]

Side remark. This thread showed me the existence of a "lzlib" library
for binding zlib with Lua [1].
When I looked at LuaForWindows distribution, it just happens that no
direct usage of zlib was included (there are however gzio and LuaZip).
I am not particularly surprised that  such a binding actually exists ;
 zlib is so common that someone would for sure have done the job.

Anyway.  A weak ago I have written a zlib binding as an example for
our modular book [2]. So I made a little comparison.
The APIs are quite different despite that the exported zlib features
are the same !
My version is much shorter (206 lines compared to 912) but lacks
":read"-like feature. Only ":add" and ":flush" are provided.
BTW, the author should consider replacing syntax like "data =
lua_tostring(L, 2); len = lua_strlen(L, 2); " by "data =
lua_tolstring(L, 2, &len); "
