Description
So, #8 says "format macros" (hard in general); #3445 suggests formatting macros using { .. } braces as a Block; #2905 proposes formatting expression-like macros...
... general solutions are hard and probably require matching the macro by path (including crate of origin) ...
... can we get half-way there with per-project configuration?
Configuration
So: could we opt-in to macro formatting by adding this to lib.rs?
// example: widget! macro (used below)
#
Example: widget
KAS (master) has a widget! macro which can be formatted like a module:
widget! {
/// A frame around content
///
/// This widget provides a simple abstraction: drawing a frame around its
/// contents.
#[autoimpl(Deref, DerefMut on self.inner)]
#[autoimpl(class_traits where W: trait on self.inner)]
#[derive(Clone, Debug, Default)]
#[handler(msg = <W as Handler>::Msg)]
#[widget{
layout = frame(self.inner, kas::theme::FrameStyle::Frame);
}]
pub struct Frame<W: Widget> {
#[widget_core]
core: CoreData,
#[widget]
pub inner: W,
}
// NOTE: `impl Self` is not valid Rust syntax, but rustfmt handles it fine
impl Self {
/// Construct a frame
#[inline]
pub fn new(inner: W) -> Self {
Frame {
core: Default::default(),
inner,
}
}
}
}
