I will explain this point in more detail if you don't mind. Here goes 
copy-pasted
1) the first the "lst" for hard disks and then
2)the second one the "sh" that makes the "lst" for partitions.
3) An "lst" for making easier to call the selection of partitions from 
inside a function or whatever.
4) An example of how this menues/selectors are called. (lst)

I'm not asking you to develop a command for giving me this lst on the 
fly adapted to the user pc. You know what I was telling before: If the 
users hard disk has only three partitions make an array with only three 
values which are the partitions.

I'm asking you to think about new features that scripting should have so 
that the developing of this command is far easy.

OFFTOPIC NOTE: I am working on grub legacy call and back commands so 
that what you see below actually works. I think this night it will work 
ok but who knows.

I was thinking about an iterator function.  Perhaps that might be the
easiest to use...  Please watch CVS closely.  I am actively working on
scripting, as much as time permits.

Yes... The thing that when meaning translation I was thinking about SGD, 
which is kind of a GUI for Grub so... I did not think about Grub 
messages but to menu entries as Marco suggested.

However you're right Grub messages could also be translated.

Currently I have SGD (only menu entries) translated to various languages 
with a three-level structure... one for algorithm... one for "kind of 
universal language" and one for the actual languages. It's implemented 
with bash variables and uses sed and other unix tools and it is not 
perfect...

I know there was this gettext thing and in the first place I didn't get 
to work it with bash (I think I needed to recompile it) so I discarded 
the idea.

Maybe I will take a look at gettext again for SG2D.

An iterator function among the various partitions of a hard disk... that 
could be interesting. Unfortunately I can't watch CVS closely so I will 
wait till you announce it in this list. :)

The iterator function should increment a variable for knowing the total 
amount of partitions on a given hard disk.

SOC - SGD based on grub2 - Menu and scripting status

[adrian15]

I've reading the G'SOC document:

http://www.gnu.org/software/grub/grub-soc.html

and I've been tented to add a new proposal for grub2.

As you all should have guessed it would a Super Grub Disk ( 
http://adrian15.raulete.net/grub/ ) but not based on grub legacy but grub2.

	If I want the project to be feasible I need that the grub2 api relative 
to menues and scriptings is fixed. That means that the name of the 
commands and its behavior don't change since I begin the project to the 
end of it.

	So here are some questions that have arised...

1) Marco Gerards: Do you think that commands/functions/variables related 
to menues files are going to change a lot?
But I don't mean RIGHT NOW. I mean in the beginnings of SOC... which I 
don't know... let's see... 23th May. (in one month time).

	If these commands are available where should I get a list of them and 
their behaviour?

2) Do you like the Super Grub2 CD name... or should it be Grub2 CD or 
Grub CD and that's all? Grub Rescue CD perhaps?

3) What features would you like to see apart from the ones that are 
already implemented in Super Grub Disk ( 
http://adrian15.raulete.net/grub/tiki-index.php?page=En )?

4) What is the best way for dealing with languages and translations when 
developing?

5) I need to define "something" (In my grub legacy fork is a menu.lst) 
that lets me choose the harddisk-partition which I want to work on. Can 
I make it easily?

Can Grub2 api write me in an array or a similar the partitions that can 
read in a given hard disk? So that if there are 3 partitions they are 
saved into an array of size 3?

I can not make such promise.  But I am open to feature suggestions as
far as I did not make any promises or so yet.

The will keep changing, I think.

Not yet.  We still hope someone will write good user documentation.

I personally do not have a strong opinion about this. :-)

We are thinking about i18n support.  This is something about this on
the wiki, I think.

You mean as a variable?  That's possible.

No, at least not yet.  Scripting is in continuous development ATM.

I don't think this part is described well in the wiki. So I describe my idea 
here:

- GRUB needs to have a locale variable to determine a language.

- GRUB needs to have gettext or something similar to translate messages.

- GRUB needs to be able to generate .po files compatible with gettext.

- GRUB needs to support message translations by scripting as well as by C 
code.

These are not implemented at all yet, but not difficult. I expect that this 
would take 2 weeks, if one works in full time.

Will this mean Adrian can use it for menu entries as well?  I think
that is what he wants to do.

In my idea, yes. I can say anything before implementing. ;)

I think this is one of the possibilities. Giving support to script in
form like this:

menuentry $gettext("My menu entry text") {

}

Though gettext is not perfect in all places, but could be enough for us.

I am still wondering what are the features of the scripting language.
Marco could you write some summary of your ideas somewhere and some
syntaxical examples?

Thanks,

That sounds sane to me.

Sure.  I wrote a lot of emails about it.  But it might be nice to have
something more coherent on the wiki.  I'll work on
that... someday. :)
