[gentoo-portage-dev] Hello! && portage UI

Hello!

I am thinking about making user interface for portage.

I see the possibility to browse portage tree, turning different filters on
and off, as it's most important feature. I dont think that it should contain
any functions for updating, emerging or unmerging or syncing at it's
beginning, as i think that i havent used portage long enough to make a clear
design of such a tool.

Anyway, package browser would be usable for me as a new user of portage.

I describe shortly, what i see as it's functionality:
* General UI, which looks like a classical e-mail client with folder-list on
left panel, mail-list on top and one e-mail on bottom. Additionally, top and
bottom panel should be together in right panel.
* Left panel contains 2 main folders -- one is to access folders in
/usr/portage/, another contains keywords like kdebase-meta (or kde-base) --
which has packages like kdegraphics-meta inside it (click +). This other
tree should be hand-made tree + "others" folder, last containing all package
groups, which are not included in this tree. At least, i think that
automation may not be possible -- it depends on structure, which i dont
know.
* Right panel, which contains tabs -- first tab is for top/bottom panels,
other are web browsers (konqueror).
* Top panel contains package list like detailed view of folders
* Botton panel contains details -- also button for opening www-address of
package in new tab.
+ there should be search feature.
+ some special folders should be added: --update world, which contains all
outdated packages jpc. As it would be slow, portage or this UI should be
cache such things and clean this cache when --sync happens.

It is possible that integration into Konqueror could be simple and usable
(like portage:/ protocol).

In future, additional features like tray-icon for autosync and
notifications, also adding packages to world and removing, could be
considered; code should be build in such way that is would be possible to
add them later in different ways.

For KDE there are 2 projects that come to mind Kuroo, and another one
that was designed to run in Konguerer, but I don't remember the name.
Kuroo is being actively developed right now, I don't recall seeing
anything recently on the other one.

If your thinking of something being coded in python so that it can
interact with and use portage code for information retrieval then check
out Porthole.  It is a gtk app not KDE, but will run on a KDE desktop.
It sounds like it already does things similar to what you had in mind.

If you wanted to port the gui code from pygtk to pyQt, I am sure that
there would be a number of KDE users that would be pleased.  I would
definitely consider adding an optional KDE interface to it. :)

Ok, i was, yes, speaking about kde.

I will check out this Porthole :) I was actually thinking more about c++,
but nothing against python -- i was quite a fan of python when i first found
it.

I'm new to gentoo, so could you tell me, where i find some clear manual for
doing the following:
* Download gentoo source of Porthole
* Change that source
* Build my version of it in such way that my portage tree is OK after that

Are --fetchonly and --usepkgonly somehow related to that?

First I would unmask it and emerge it so that you have all dependencies
installed.  enable the debug use flag or emerge pycrash-0.43 separately.

# echo =app-portage/porthole-0.5.0 /etc/portage/package.unmask
# echo app-portage/porthole /etc/portage/package.keywords
# emerge porthole

If you like it and want to make a kde interface for it,

Go to our sourceforge page and do a cvs checkout.
http://sourceforge.net/projects/porthole/

> * Change that source

cd into the directory, edit as desired

then run it from a terminal:

# ./porthole -l -d


Also sign up to the 2 mail lists for porthole so we can discuss any
problems, etc..  This list is for portage development.

Then any changes can be diffed for commit.

cvs diff -u > somefile

Of course I will have to make changes to the interface loading so that
your changes won't kill the gtk interface code.

--fetchonly will just get the tarball downloaded into the distfiles
directory.

--usepkgonly is for telling emerge to use binary packages only.

Ok, i will finish this chat about making portage cache, then learn
portage code, then write basic sql modules and when this thing is
running, i am more able to be involved in portage GUI as i can
understand background of portage, then ...i hope you have time to wait
for me :)

For the record: Kuroo is known to be conceptually broken (uses the cache 
directly), but the author is looking to fix that in a future version.
Generally writing portage utils in languages other than python is 
difficult as you can't use the primary API directly.

There seems not to be c++ bintings to python, anyway there is
dev-python/sip. I havent done such thing, but i suppose that it would
not be impossible to start portage inside Kuroo as a thread, then
interact with this thread, having sip between them. If it's used for
creation of PyQt, such two-way interaction should be possible.

Re: [gentoo-portage-dev] Hello! && portage UI

[tvali]

I looked over that:

SIP also makes it easy to take a Python application (maybe a
prototype) and selectively implement parts of the application (maybe
for performance reasons) in C or C++.

This could mean that portage could be made fully compatible with c++
app? Again, havent tried/tested, just assuming :)

Actually, C++ being strongly related to C, can just use the C python 
api's. As such it could directly interface with python, and use the 
python portage api.

If you could demonstrate an 'import portage' and a simple
printf("PORTDIR=%s\n", PORTDIR); in C I'd be highly interested.

Could :P

Python has this interactive interpreter, what every scripting language has.

If you are able to run command-line app, send keyboard input and catch
it's output, you're done with it.

You can also write some small python function, which will parse python
variables into some form, which you can simply parse into something,
what is easily readable in C.

An example please. 5 lines of code have more meaning than ~30 emails on

Re: [gentoo-portage-dev] Hello! && portage UI

[tvali]

Not so simply :)

This is a clear way, i think. I havent c++ installed right now as it
gives some errors and i havent too much urge yet.

Anyway, with piping..
python > /root/test.out < /root/test.in

You can write things like "import module" to test.in, then use result
from test.out.

I did write words "print 'hello!'" to test.in, which left 1 word
"hello" into test.out -- of course it's slower than getting it work as
realtime interaction :)

http://www.math.mcgill.ca/services/linux_basics.php -- there is also
command1 | command2 for piping between apps.

Tcl script: http://www.cs.mun.ca/~donald/msc/node72.html

When i get kdevelop to work here, i will look this thing more and
produce some code -- i like it more than Kate :) Anyway, i think that
it shouldnt be hard at all :) And using io files, it's achievable now,
too.

Try attached :)  Had a go 'coz I was curious.  Compile with:

gcc -o getportdir getportdir.c -lpython2.4

Does the equivalent of:

#!/usr/bin/portage
import portage;
print portage.settings["PORTDIR"];

(more or less).  Docs on the API itself (which comes with Python) are at
http://docs.python.org/api/api.html

So I was the last one :)

My example is using python interpreter -- it's maybe simpler to use in
many cases, but theoretically slower.

It is, anyway, not so advanced to import portage, but you can add that line ;)

sorry
lines
    char tt;
    for (tt=0; tt<40; tt++)
      fputc(tt, inputf);

/.../

    fputc(EOF, inputf);

are not needed at all and do nothing -- i was just testing a thought
before i catched how those pipes and forks work in linux :) i have
mostly done things in windows and c++ and WinApi so i dont catch
everything immedietly yet :)
