It might be nice to have a dh_alternatives scripts to automatically write
any wanted update-alternatives commands for the postinst/prerm scripts
by debian/alternatives or debian/<package>.alternatives, like follows:
(I don't have good idea about debian/alternatives format...)

#!/usr/bin/perl -w

BEGIN { push @INC, "debian", "/usr/share/debhelper" }
use Dh_Lib;
init();

foreach $PACKAGE (@{$dh{DOPACKAGES}}) {
	$TMP=tmpdir($PACKAGE);
	$alternatives=pkgfile($PACKAGE,"alternatives");
	
	if ($alternatives ne '') {
		if (! $dh{NOSCRIPTS}) {
			open(IN, "<$alternatives") || die "$alternatives: $!";
			while (<IN>) {
			    # read alternatives file
			    # and check it
			    autoscript($PACKAGE,"postinst",
				       "postinst-alternatives",
				       "s:#ALTINSTALLARGS#:$altinstargs:");
			    autoscript($PACKAGE,"postrm",
				       "postrm-alternatives",
					"s:#ALTRMARGS#:$altrmargs:")
			}
		}
	}
}

This is the main reason I've never come up with such a script. I dislike
this config file format, but I can't come up with a better one.

I think this format is too obscure to be useful. Raw update-alternatives
commands in a postinst are more understandable.

Debhelper postinst additions scripts cannot echo anything to the user
without pausing, because that is a villation of policy. I really don't want
anything debhelper adds to maintainer scripts to output anything at all
except error messages. I think the messages update-alternatives outputs when
something in on manual are good enough.

> Would you be interested in including this in debhelper?

Yes, if we can come up with a better config file format.

Sorry for respawning this issue after such a long time...

A better config file format could possibly be one which mimics the way 
update-alternatives is called: it would simplify things only if you consider 
that bugs caused by update-alternatives --remove commands being out of sync 
with their --install counterparts.

The proposed format is like the following:

<link> <name> <path> <priority>
 <slave-link> <slave-name> <slave-path>
 ...

<link> <name> <path> <priority>
 ...

Where slave lines (if any) begin with any amount of white space and an empty 
line separates stanzas (if there are more than one).

Using the following format, the config file for e.g. mawk would be:

/usr/bin/awk awk /usr/bin/mawk 5
 /usr/share/man/man1/awk.1.gz awk.1.gz /usr/share/man/man1/mawk.1.gz
 /usr/bin/nawk nawk /usr/bin/mawk
 /usr/share/man/man1/nawk.1.gz nawk.1.gz /usr/share/man/man1/mawk.1.gz

And for e.g vim, it would look like:

/usr/bin/vi vi /usr/bin/vim 120
 /usr/share/man/man1/vi.1.gz vi.1.gz /usr/share/man/man1/vim.1.gz

/usr/bin/view view /usr/bin/vim 120
 /usr/share/man/man1/view.1.gz view.1.gz /usr/share/man/man1/vim.1.gz

/usr/bin/ex ex /usr/bin/vim 120
 /usr/share/man/man1/ex.1.gz ex.1.gz /usr/share/man/man1/vim.1.gz

/usr/bin/editor editor /usr/bin/vim 120
 /usr/share/man/man1/editor.1.gz editor.1.gz /usr/share/man/man1/vim.1.gz

(I admit that, in this case, a for loop in the maintainer scripts would be 
less redundant, but a package maintainer can choose whether to use this 
facility.)

Regards,
Danilo

Sorry for respawning this issue after such a long time...

A better config file format could possibly be one which mimics the way 
update-alternatives is called: it would simplify things only if you consider 
that bugs caused by update-alternatives --remove commands being out of sync 
with their --install counterparts.

The proposed format is like the following:

<link> <name> <path> <priority>
 <slave-link> <slave-name> <slave-path>
 ...

<link> <name> <path> <priority>
 ...

Where slave lines (if any) begin with any amount of white space and an empty 
line separates stanzas (if there are more than one).

Using the following format, the config file for e.g. mawk would be:

/usr/bin/awk awk /usr/bin/mawk 5
 /usr/share/man/man1/awk.1.gz awk.1.gz /usr/share/man/man1/mawk.1.gz
 /usr/bin/nawk nawk /usr/bin/mawk
 /usr/share/man/man1/nawk.1.gz nawk.1.gz /usr/share/man/man1/mawk.1.gz

And for e.g vim, it would look like:

/usr/bin/vi vi /usr/bin/vim 120
 /usr/share/man/man1/vi.1.gz vi.1.gz /usr/share/man/man1/vim.1.gz

/usr/bin/view view /usr/bin/vim 120
 /usr/share/man/man1/view.1.gz view.1.gz /usr/share/man/man1/vim.1.gz

/usr/bin/ex ex /usr/bin/vim 120
 /usr/share/man/man1/ex.1.gz ex.1.gz /usr/share/man/man1/vim.1.gz

/usr/bin/editor editor /usr/bin/vim 120
 /usr/share/man/man1/editor.1.gz editor.1.gz /usr/share/man/man1/vim.1.gz

(I admit that, in this case, a for loop in the maintainer scripts would be 
less redundant, but a package maintainer can choose whether to use this 
facility.)

Regards,
Danilo
