Customizable naming templates (e.g., namespace prefixing)

[dignifiedquire]

I was wondering if there is a way to automatically add a prefix to types/functions etc when generating the C definitions, sth like this:

#[ffi_export]
fn foo() {
  // ..things
}

#[derive_reprC]
pub struct MyStruct { /* ...  */ }

typedef struct { /* .. */ } PFX_MyStruct;
void pfx_foo() {
}

as currently I have to add the PFX prefix manually to my types and functions in rust, which makes it very unidiomatic, and easy to forget.

Agreed. This more general query thus supersedes #70, and ought to be featured rather soon 🙂

[dignifiedquire]

it seems there should be support for this now, but using .with_naming_convention seems to not change any thing currently. Is that expected?

[danielhenrymantilla]

Yes and no: I haven't had the time to cater to the finishing touches for the header generation, which I would like to make it as extensible as possible, with a guide about this, c.f. the languages/{c,csharp}.rs files; so some certain parts are currently empty/shallow scaffolding for when they finally do something in the future.
It is, however, a genuine oversight for this scaffolding to have ended up in public API, such as with_naming_convention() 😅
