I asked this question several years ago
(https://cygwin.com/pipermail/cygwin-apps/2018-October/039451.html), but I'm
repeating it, in a more specific form, in the hope that setup has progressed
to the point where I get a different answer.
There are currently five emacs packages: emacs-common, emacs, emacs-X11,
emacs-w32, and emacs-lucid. The first includes things that are needed by each
of the other four, and those four each include an emacs binary. The binary in
the emacs package is /usr/bin/emacs-nox.exe. The other packages contain
/usr/bin/emacs-X11.exe, and so on.
This way of naming the packages doesn't really reflect the contents of the
emacs package. It also means that anyone who installs emacs gets
emacs-nox.exe, even if they plan to use one of the other three binaries.
I would rather rename the current emacs-common package to emacs and the
current emacs package to emacs-nox. But then the new emacs would have to have
a way of requiring the installation of at least one of emacs-nox, emacs-X11,
emacs-w32, or emacs-lucid. Is there any way to do this with our current setup
machinery?
My idea three years ago was to have the new emacs package require a "feature"
called, for instance, emacs-bin, and then have each of emacs-nox, emacs-X11,
emacs-w32, emacs-lucid "provide" that feature. This is what Fedora does. Achim
didn't think this was feasible without major changes in setup. Is that still
the case? If so, can anyone think of another way to accomplish what I want?
Hi Ken,
Achim recently restructured gnuplot; I used to install gnuplot, gnuplot-base now
obsoletes that, and that is all I have installed; alternatives handles the
priorities if different packages provide gnuplot:
https://cygwin.com/git-cygwin-packages/?p=git/cygwin-packages/gnuplot.git
gnuplot-base
depends2: cygwin, libcairo2, libcerf1, libgd3, libglib2.0_0, liblua5.3,
libpango1.0_0, libreadline7
gnuplot-X11
depends2: cygwin, gnuplot-base, libX11_6, <BASE-DEPENDS2>...
gnuplot-qt5
depends2: cygwin, gnuplot-X11, libQt5Core5, libQt5Gui5, libQt5Svg5, libgcc1,
<BASE-DEPENDS2>... libstdc++6
gnuplot-wx
depends2: cygwin, gnuplot-X11, libgcc1, <BASE-DEPENDS2>... libgtk3_0,
libstdc++6, libwx_baseu3.0_0, libwx_gtk3u3.0_0
This is very similar to what I currently have in emacs, although with better
names. gnuplot-base is comparable to emacs-common+emacs. It doesn't achieve
what I was asking for. But if what I was asking for isn't possible, I might
still do some renaming, to make the contents clearer.
Thanks.
Ken
