# Changelog

## v0.5.0 - 2026-06-15

- Add template includes.
- Add composable RustQ splice groups.
- Use plain keyword splices for composition.
- Add structured include diagnostics.
- Add rustfmt option.
- Add generic Rust body/control-flow builders:
  - `Rust.block/1`
  - `Rust.let_/2`
  - `Rust.let_mut/2`
  - `Rust.assign/2`
  - `Rust.call_stmt/3`
  - `Rust.return_if/2`
  - `Rust.if_/3`
  - `Rust.if_let/4`
  - `Rust.match_/2`
- Document macro token placeholder limitation.

## v0.4.0 - 2026-06-06

- Add generic Rustler builders for atom decoders, atom dispatch functions, and
  keyword/options helper functions.

## v0.3.0 - 2026-06-06

- Remove the generic Rustler schema field group DSL. Prefer explicit fields in
  RustQ schemas or project-specific macros for domain shorthand.

## v0.2.2 - 2026-06-03

- Add `RustQ.Rustler.resource_handle/2` for generating a Rustler resource plus
  a decoder for Elixir-facing resource handle structs/maps.
- Add Rustler schema field groups for reusable field sets with `use_fields/1`.
- Let Rustler schema nodes override generated Rust type names and Elixir module
  names with `rust:` and `module:`.

## v0.2.1 - 2026-06-03

- Add `RustQ.Rustler.nif_export/2` and `nif_exports/1` for generating exported
  Rustler NIF functions that delegate to handwritten implementation functions.

## v0.2.0 - 2026-06-02

- Replace the separate `__expr_`, `__type_`, and `__splice_` placeholder
  prefixes with one visually distinct `__rq_` placeholder prefix.
- Templates now use forms like `__rq_Name`, `__rq_value!()`,
  `__rq_fields: (),`, and `__rq_items!();`.

## v0.1.2 - 2026-06-02

- Let Rustler schema field types reference schema nodes and tagged enums by
  schema name, so examples can use `Content` instead of generated Rust names
  like `ExContent`.

## v0.1.1 - 2026-06-02

- Keep the packaged NIF crate out of parent Cargo workspaces when RustQ is used
  inside workspace-based projects.

## v0.1.0 - 2026-06-02

Initial release.

- Parse, validate, render, bind, and splice Rust templates from Elixir.
- `~R` sigil for inline Rust templates.
- Rust fragment builders for functions, structs, enums, impls, fields, constants, uses, modules, and type aliases.
- Rustler helper generators for atoms, NIFs, resources, option decoders, term helpers, term decoders, NIF structs, tagged enums, cached atoms, safe term builders, and explicit raw `NIF_TERM` builders.
- `rustq.exs` manifest DSL plus `mix rustq.gen` for generated file syncing and stale checks.
- Rustler schema DSL for generating Rust NIF structs and tagged enums from Elixir schema definitions.
