I am new to *writing* to mailing lists so if I've done something wrong
please forgive me.

I would like to "cygport" the Mudlet GPL MUD {Multi-User Dungeon} client
to Cygwin - I have a cygport file (and currently a patch) that works to
compile a workable binary of the 3.1.0 release available as a tarball
from https://github.com/Mudlet/Mudlet/archive/Mudlet-3.1.0.tar.gz {other
distribution methods are available!} but Mudlet possesses a Lua
sub-system that users/MUD system operators can use to provide additional
functionality and this is currently proving awkward!

The issue I am having is that Mudlet needs some Lua "modules" to operate
and Cygwin currently only provides a sub-set of the needed ones, the
lua-file-system "lfs" IS available but also needed is:

* "rex_pcre"

* "zip"

* "luasql.sqlite3"

What is the best way to get those "run-time" dependencies into Cygwin? I
have found "luarocks" packaged versions (as "lrexlib-pcre", "luazip" and
"luasql-sqlite3" respectly) but it is not immediately apparent how I
might use that to generate the things needed as part of the "cygport"
process.

For the record Mudlet {https://www.mudlet.org} is carried on, at least,
the Debian & Ubuntu GNU/Linux distributions and it's developers do
target and aim to provide Linux, macOs and Window platform binaries as
well as source code. However the Windows one does suffer a little in
bug-fixes and performance because it is difficult to put together a
development platform (IMHO) for that OS that will work in both a 32 and
a 64 bit environment (as until very recently) the Qt people only made a
32 bit FOSS development environment available with a built-in Mingw
compiler and, of course, the alternative free MSVC compiler can not be
used to make binaries that can be distributed under GPL terms; the need
to compile/source the other libraries that Mudlet uses in a form that is
compatible with anything compiled with such a Qt/Mingw combination makes
the Cygwin environment much more user friendly for normally *nix system
based developers...

I should perhaps point out that I *am* one of the "upstream" i.e. a
member of the team that call ourselves the "Mudlet-makers" and I have
been using Cygwin on and off for years now... 8-)

I do miss the Qt Creator IDE when I switch to the Cygwin environment
though. 8-(

I imagine luarocks may work similar to Perl's CPAN on Cygwin: some
Perl modules can be installed via Cygwin's setup.exe (e.g. perl-Tk,
perl-Data-Dump), the rest can be installed with the CPAN client.

IANALU (I am not a Lua user), but it seems to me that these Lua
modules should be outside the scope of Mudlet's cygport. Mudlet should
simply require these modules to be present for its Lua subsystem. The
user can be directed to install the required modules by whichever
means available (rex_pcre and luasql.sqlite may be too complicated to
be installed by luarocks; they may need to be made into Cygwin
packages like lua-file-system).

Mudlet should not mess with the user's Lua installation.
