again on snippets

Still trying to make yasnippet even faster for c++ coding.

So suppose that I want to create a friend << operator

Something like:
--8<---------------cut here---------------start------------->8---
    friend ostream& operator<<(ostream& s, const PadCoordinate& c);
--8<---------------cut here---------------end--------------->8---
and this would be the beginning of the definition
--8<---------------cut here---------------start------------->8---
ostream& operator<<(ostream& s, const PadCoordinate& c)
{
--8<---------------cut here---------------end--------------->8---

so basically it's the same thing but in the implementation and header
file there are some differences, and it would be good to avoid
duplication.

Is there a variable (is-header-file) in cc-mode (can't find it)?

And what about the different styles, someone like

fun() {
}
someone
fun () {
}
or
fun()
{
}

and so on, maybe the snippet should output with the correct style given
in the configuration.

Hi,

it's not just yasnippet:
as far as speed is at stake

have a look into python.el, how loop-templates
are built in.

I had a look and it uses skeleton, which is fine but yasnippet is much
more powerful.
The best thing maybe is just one function to check if it's a header or
not and then just expand accordingly.

But I would need a meta-snippet because all the functions can be
declared in more or less the same way, right?

so a meta-snippet would be

<return type> (optional namapsace identifier::)<name> (<parameters>)

I'm wondering what makes you say that,
