Dear Fink developers,
I'm currently trying to write a few packages for extensions for scsh
(the Scheme Shell). To summarize quickly, scsh is a scripting language
similar to Perl/Python/Ruby/etc. for which some libraries, which I'll
call modules below, exist. I'd like to write Fink packages for these
modules, and I have some questions related to that. To make the
discussion which follows clearer, let me quickly explain how scsh
modules are managed.
First of all, in order to install scsh modules, one has to have at
least scsh 0.6.6 installed, because some things are missing from
earlier versions. There is a Fink package for scsh 0.6.6, so things
are fine in that respect. Once scsh itself is installed, the module in
charge of managing scsh modules, called "scsh-install-lib", has to be
installed first. Finally, one can use the "scsh-install-lib" module to
install further modules, written by the scsh community.
I'm trying to write Fink packages for the "scsh-install-lib" module,
and then for various existing modules, like "sunterlib", "sunet", and
so on.
The first problem I have is one of dependency. It happens that scsh
modules are installed in directories which explicitly refer to the
major and minor versions of scsh to which they belong, e.g.:
<prefix>/share/scsh-0.6/modules/<module-name>/scheme
^^^^^^^^
where <prefix> is the prefix given at installation time (would be /sw
for Fink) and <module-name> is the full name of the module, including
its version.
Since this directory (and the code it contains, in fact) is specific
to scsh 0.6 and is not expected to work with scsh 0.7, I'd like to
specify that in the "Depends" field. But I'd also like to specify that
the version of scsh has to be greater or equal to 0.6.6, for the
reasons given above. The following seems to work, but I wonder if
there's a cleaner way:
Depends: scsh (<< 0.7.0), scsh (>= 0.6.6)
The other problem is one of naming. Since I expect that in the long
run there will be quite a lot of Fink packages for scsh modules, maybe
I should name them in some consistent fashion, or even put them in
their own section. Any suggestion in that respect?
Thanks,
Michel.
