[gentoo-dev] something like debconf for gentoo?

[thomas weidner]

Hi,

debian has a nice system for packages displaying messages or asking
questions, or even to store package spezific informations. There are
CLI, textmode GUI, and even X11 frontends. I think this would also be a
good idea for gentoo. what do the others think?

Something like this would be handy.  Even in FreeBSD, they have sort of
an interactive questionaire thing when you build something from Ports. 
For example, when you try to build Samba in Ports, it brings up a text
dialog with a bunch of checkboxes for all the Samba options like ACLs
and LDAP support, and you check off the ones you want; obviously then it
adds those to the ./configure line it uses in the Makefile.

I know Gentoo relies on USE flags and they are all magical and stuff,
but you can't have a USE flag for *everything*.

Sure you can - that's what local USE flags are for.

/usr/portage/profiles/use.local.desc

Yes, but it would simpler to have an interface than to looking in use.local.desc file every
time you emerge a package.

BTW, this interface would be easy to create ! The emerge process should look if the current emerged
package is in the file, and would provide some tunable options before compiling.

The problem is, emerge should be non-interactive, meaning I could walk
away for 12 hours and have it be done when I come back, not have some
silly gentooconf screen waiting on the second of 250 packages. That's
why USE flags are nice. Of course, if one could go through gentooconf
all at once before starting, that might work too.

i'm not argueing against the idea of gentooconf, but you could do:
`emerge pkg -pv`, look at the list of useflags utilized, and then go from 
there ...

Like debconf is only called when all packages are fetched, gentooconf
should be called between fetching files and compiling.
It's similar to the grouped log in emerge (display all messages in 1
shot at the end of emerging).

What about ufed? It is already done and has the required capability (checkboxes
and stuff).  The only thing ufed needs before becoming what you want is the
capability to let you choose what flags you want to configure.

For example if ufed has the capability to be run as:

# ufed ssl pam ipv6

and then only let you configure the three flags "ssl", "pam" and "ipv6", then,
you could configure your packages before emerging them with this.

Example. You want to configure the following command:

# emerge -pvU samba proftpd

You configure it with this:

# emerge -pvU samba proftpd | 
	grep '^\[ebuild'    |
	cut -f2- -d]        |
	cut -f3- -d\        |
	sed -e 's/[-+]//g'  |
	xargs ufed

I actually even coded the changes I had in mind. You may want to use the shell
script I attach for configuring though since the code above is a little too
long to type every time by hand.

Please test and if the devs like it -- apply.

that's a good idea,scan all packages first for gentooconf things,then do
the gentooconf stuff and then compile 250 packages non-interactively for
12h. (there aren't only useflags things to do with gentooconf)

There is allready a command line tool for manipulating use flags 
called euse.  Its part of the gentoolkit package.

I think it would be better to use euse for this type of application.
