v0.3.2

Added support for leptos-rs/leptos#2534 and some minor span improvements.

Full Changelog: v0.3.1...v0.3.2

v0.3.1

Minor fix to improve r-a support, see #13.

Full Changelog: v0.3.0...v0.3.1

v0.3.0

A whole ton of fixes and improvements!

BREAKING:

• use: directives now call .into() on their values, which is what leptos::view! also does. See leptos-rs/leptos#2248
• Events like on:click are now always delegated - they were previously always undelegated. This may break some event listeners' behaviour.

Enhancements:

• Support for qualified paths in component names like leptos::Show.
• Generics can be used with or without the turbofish.
• Support for the :undelegated modifier on event listeners.
• Significantly improved error recovery, spans, messages and syntax highlighting.

Full Changelog: v0.2.3...v0.3.0

v0.2.3

Compatible with leptos 0.6! (by just fixing some tests :))

One new feature: children blocks can be wrapped in either braces or parentheses. No functional differences, just a stylistic choice.

mview! {
    p("these are " em("my") " " strong("children"))
}

Full Changelog: v0.2.2...v0.2.3

v0.2.2

Minor update to what is being spanned due to updates to proc macro stuff in rust-analyzer. All tokens in quote_spanned! will show their documentation at that span, leading to component names having documentation for things like std and vec!.

The macro now adds a #[allow(unreachable_code)] for better error messages, but means that this lint may be disabled in attributes.

Hopefully nothing else has broken :)

v0.2.1

Totally didn't forget to make a github release

Copied from CHANGELOG.md:

Hopefully no breaking changes, just a whole bunch of new DX features!

Features:

• Support for slots! Prefix the slot element with slot: to use it as a slot. The parameter name in the parent component must be the same name as the slot, in snake_case.
  • See Slots for more details.
• A new value shorthand: f["{:.3}", some_number()]: adding the f prefix adds format! into the closure; equivalent to [format!(...)] or {move || format!(...)}.
• On components, if you have the parameters #[prop(into, optional)] class: TextProp or #[prop(optional)] id: &'static str, you can use the selector shorthand Component.some-class #some-id to add it to these attributes, and/or the class: directive for reactive classes.
  • impl Default for TextProp is currently in the Leptos git main / future v0.5.3 release; for 0.5.2 or earlier, you need to use #[prop(default="".into())] instead of optional.
  • Reactive classes in this way are not very performant as a String is constructed every time any of the signals change. If you only use the selector shorthand, they will be compiled into one string literal (no performance downsides).
  • This is also supported on slots, using the same fields.
  • See Special Attributes for more details.

Enhancements:

• Fixed up a whole lot of spans to improve a whole bunch of error messages: hopefully, there are no more errors that cause the entire macro to be spanned, errors should always be localized to a relevant spot.
• Better rust-analyzer support in some invalid macro situations.
• Better syntax highlighting for the selector shorthand on HTML elements.

---

Other minor things:

• Removed extra syn features, now this just depends on syn with its default features (no "full" or "extra-traits"). This doesn't do much because Leptos requires these features anyways.

Full Changelog: v0.2.0...v0.2.1

v0.2.0

Supporting directives from Leptos 0.5.2, as well as some breaking changes cause I'm indecisive :)

Breaking Changes:

• #4: Rename macro from view! to mview!.

  A full-word search-and-replace for view! -> mview! and leptos_mview::view -> leptos_mview::mview should fix everything.

• #3: clone: directive now takes a single identifier, clone:thing instead of clone:{thing}.

Enhancements:

• #3: added use: directive to elements. Syntax is the same as leptos, use:dir or use:dir={param}.

v0.1.0

First release! See README.md for details.
