v0.5.0

Breaking changes

• Require vize 0.17 and Volt 0.20. Vize's Vize.split_template/2 replaces vapor_split. It works from Vize's L2 semantic IR instead of scanning Vapor's template HTML, so PhoenixVapor no longer depends on locating elements in generated HTML. PhoenixVapor.render/2 takes a template string or a PhoenixVapor.Template.
• Compiled templates are %PhoenixVapor.Template{} structs, which inspect as their file and slot count, instead of maps.
• An expression that fails when rendering, such as a call to something that isn't a function, raises PhoenixVapor.ExpressionError with its file, line, and column, where it rendered nothing.
• A component, function call, or macro call the server can't render is a compile error outside hybrid mode, and a warning in it; it used to render nothing.
• Reactive templates carry data-vapor-keys beside data-vapor-statics; the browser code in this release reads it.

Added

• Components imported from .vue files render on the server, in every mode: props, slots and scoped slots, <slot> fallbacks, and fallthrough attributes merged into the root element.
• Helpers imported with with { type: "macro" } run at compile time when their arguments are known then, so variant helpers such as tailwind-variants cost nothing when rendering.
• Compile errors and warnings point to the line in the .vue file, and editors show them there.
• Function components from the __components__ assign receive default slot content as inner_block.

Fixed

• Attributes render as Vue's server renderer does: null and a false boolean attribute are left out, where disabled="false" made an element disabled, and class and style take objects and arrays. An object literal such as :class="{ on: active }" used to evaluate to nothing.
• v-show merges with the element's style, and v-model renders a checkbox's or radio's checked state and a textarea's content.
• v-for binds the index, or a map's key and index, to its other aliases.
• Interpolated objects and lists display as JSON, as in Vue.
• A root v-if rendered its first branch twice.
• A v-if, v-for or component re-renders when an assign its content reads changes, not only its condition or source.
• Reactive templates patch text that mixes static text and several values, such as Doubled: {{ n }} · {{ label }}, directly, and decode HTML entities in patched text. A diff that also changed a value the patcher couldn't write was half applied.
• A component prop bound to a list or map keeps its value instead of raising.
• Relative imports in a hybrid component's client module resolve from where the module is written.
• Full-runtime components resolve imports through the project's Volt aliases, and a resolution failure raises a readable error.
• Reactive LiveViews recompile when their .vue file changes.
