[gentoo-dev] emerge with interacitve use

[Panard]

[-- Attachment #1: Type: text/plain, Size: 1107 bytes --]

Hello,

	After some experiencies with emerge, it could be great that to do an emerge 
with USE interactive :

$ emerge -I php
>>> ...
Use Java [Y/n]?
Use X[y/N] ?
....

I found, that there are too many errors due to USE vars that we forget  to 
disable or enable...

So I have taken my hands and my vim, and tried to do this, it gave a good 
result.

I join the script, its name is emerge-interactive, this is in fact the emerge 
script with my modifications (line  1840 to 1877)... place it in the 
directory
/usr/lib/portage/bin
then
ln -s /usr/lib/portage/bin/emerge-interactive /usr/bin


To use the interactive mide, use
$ emerge-interactive -I or --interactive ....

This is my first gentoo and linux contribution so I'm waiting for some 
feedback, impression, and sure critiques and amelioration (this is the first 
time I script in python, so be indulgent !!)

Thanks!

Panard

why not link the interactive build options to -I ... so to have an interactive merge you do 

emerge -u vpopmail -I 

so I can tell the damn thing not to use mysql ;P 

and emerge -u qmail 

for non-interactive ?

Having had my wrists slapped by seemat for having an interrative build process 
I don't like your chances and to be quite honest unless there was someway to 
control globally enable/disable interactive ebuilds I think I would find it 
very painful very quickly.

Re: [gentoo-dev] emerge with interacitve use

[Eric Noack]

cool idea, but how about printing the list of supported usevars,
and the list of USE's taken if -I would not have been specified 1st?


>emerge -I bla
>...
>bla supports: X, gnome, kde, java, mmx
>default USE: X, kde
>...
> X [Y,n]?
> gnome [y,N]?
>...

without the questioning if -p (--pretend) is used

what about if
emerge -u -I world
is specified, or more than one package is emerged at a time ?
ask for every ebuild seperately? or ask for all of them on start?
wouldbe better i think because you can go asleep for a 6 hours emerge kde, or
-u world if world includes openoffice or such...

what do you think?

no It didn't work now with world or system keywords....


It should work with multiple packages, ebuild, tbz, and ask separatly for 
each... 

However, the list of packages is just the list that you give in arguments, it 
wouldn't ask for packages that an ebuild depend or rdepend (too many ask for 
one or two ebuild)... but if you think that is a good idea, perhaps it will 
be fine to work about this....

To test the interactivity, use -p option, interactivity will have the same 
behaviour...



I just hope that my poor english is quite understandable....



Thanks for your interest!

Re: [gentoo-dev] emerge with interacitve use

[Sergey Kuleshov]

Hey, I really like this feature! It really helps (anyway it's better that 
looking in the .ebuild file and sort out what are the optional dependencies.)

The thing I did not get is why is it sometimes dispalying the Disabled ..... 
text ans sometimes not?

P.S. What about enchancing it with some ncurses interface to make it really 
intteractive?

Very nice.

I think with a user interface like ufed it could be merged to the
true emerge.

Thanks for the contribution

Re: [gentoo-dev] [update] emerge with interacitve use

[Panard]

Hello,

	the interactive system work now with --update and world or system (this is a 
big evolution)

For the storage of the USECUSTOM, I didn't have any idea to do this after the 
package has been merge, so I've pu this file in /var/tmp/portage/...... 
waiting for a better solution.

When we upgrade un package, the script will search for a USECUSTOM file from 
the previous versions.

Now there is two important point :
- find a solution for storage of USECUSTOM file
- make a diff between a USECUSTOM from old package to new USE vars (I will 
work on it tomorow)

these is the link to downlode the new version:
http://data.inzenet.org/gentoo/emerge-interactive.bz2


This script must be hard tested !

Thanks

Panard

This is an interesting idea, but can cause a lot of problems... It
has potential after 2.1 is released, but I don't recommend doing
things this way right now.

If you merge applications without a specific flag for a dependent
package, and then merge a package with that specific flag, it may
very well assume that the support you requested is there.  Little
errors may creep up on you. While this should be fairly harmless,
it might be a little annoying.

Portage will gain a lot more support for SLOTS, USE, and keywords
in the 2.1 series. It'll actually allow dependence based on a USE
setting and the child's build settings. It will remember them for
future emerges on a per-package basis as well.

If you make modifications to portage, I'd really appreciate it if
you would post patches on bugs.gentoo.org. It'll give me a chance
to look the changes over and give feedback as well as consider it
for integration into portage. (diff -u, greatly prefered)

This one in particular I'd rather see as a front-end instead of a
direct integration like this. Sticky flags (which will show up in
2.1) will feed from the command line and will have a lot of rules
regarding how use flags are set for a session.  This method steps
around portage's ability to determine Sticky (persistant, limited
flags set for specific packages) flags. It might end up causing a
lot of rebuilding due to global use flag changes.

If you continue with integrating it, just make sure you follow the
code changes that are coming up this summer, and perhaps it might
be adopted in one form or another.

Hrm...this is interesting.  I have a possible suggestion.  

Why not have an optional flag to start a curses interface.
In the curses interface, it lists all the ebuilds that'll be
built for the typed command, and you select the ones you want
to modify, and make the appropriate changes.

Once you've made some changes you can hit an update button to have
it recheck dependencies to make sure everything is consistant given
the new use flags.

Repeat until you're happy, then okay the build process and the rest
continues unattended.

I (personally) think this should be optional, as for single ebuilds
and such it'd be really annoying to have to work with a curses interface
versus the Y/n.  But for larger ebuilds like say world or system, it
would be much cleaner, and likely less problematic.

Hi,

Ok, I've correct some bugs, and do the USE flags diff between a new and an old

look at this link for patch and script:
