Re: [orca-list] Orca: Support for Multilingual text

HI,

I'm also curious about the configuration issue mentioned in some of
the relate bugs.  If I was implementing this I think what I'd do is
something like this.

Irst lets declare a struct for what options a voice profile has like
this

struct voice_profile{
char *name; // why not mane it
char *lang;
char *synth;
int rate;
int pitch;
... // some more stuff we'd like to have
};

Then we can keep a circular linked list of these structs and have
keystrokes to move around the circle.  We could use some other data
structure, but who likes corner cases.

Then we have to read and write this to a config file.  It sems like
this is fairly easy if we import the config fle like we do know, or
read and parse it, but I'm not sure I see an easy way to do it with
gconf.  I admit to not knowing much of anything about gconf or
gsettings, but it seems like it can only have mappings from a given
set  of keys to values?  For importing a file I'm assuming that python
allows one to statically declare an array of structs or classes like
in c something like this.

struct profile_list[] = {
{"main", "en_us", "espeak", 4, 5,},
{"alternate", "en_gb", "flite", 4, 5,},
};
