Unreleased

v0.2.0 (2026-07-14)

Added

  • rails g briefly:install — a Rails generator that writes config/initializers/briefly.rb: a working App facade plus a commented, concern-grouped map of every shortcut use "rails" installs. Pass a name (rails g briefly:install Facade) to rename the constant; re-run it after upgrading to refresh the map, as Rails prompts before overwriting. It loads only under rails generate, so no Rails runtime dependency is added.
  • Briefly::Rails::Config gains error (Rails.error, the framework's handled-error reporter) and config_for (per-environment YAML via Rails.application.config_for). Both are live lookups; config_for takes an argument, so it never memoizes — compose one that does by chaining .memoize onto a shortcut: shortcut(:x) { config_for(:x) }.memoize.
  • Briefly::Rails::DB gains connected_to, reading and writing for multi-database routing. connected_to forwards the full Rails surface (role:, shard:, prevent_writes:, custom roles); reading/writing are sugar that pin their role and forward the rest. base must be ActiveRecord::Base or an abstract connection class; a concrete model raises NotImplementedError.
  • Briefly::Rails::DB gains select — a raw-SQL read through select_all, returning an ActiveRecord::Result on the query-cache-preserving path, with the same positional and named bind-safety as query. query keeps running arbitrary SQL (writes and DDL included) via exec_query.
  • Briefly::Rails::Env gains dev? and prod?, aliases of development? and production?.
  • Briefly::Rails::Instrument — a new "rails/instrument" pack with one instrument shortcut over ActiveSupport::Notifications.instrument(name, payload) { }. Usable on its own; use "rails" includes it, so App.instrument comes for free.

Changed

  • BREAKING: Facade management moved behind a single App.briefly accessor — App.briefly.configure, App.briefly.shortcuts, App.briefly.shortcut? and App.briefly.clear_memos!. This frees configure, shortcuts, shortcut? and clear_memos! for use as your own shortcut names; only briefly, inspect and to_s stay reserved on the facade's public surface.
  • BREAKING: Briefly::Rails::DB#connection/#conn is now an auto-releasing block that forwards to base.with_connection, yielding the leased connection and releasing it at block exit — the shape of transaction. It requires a block; the old bare base.lease_connection accessor (held on the thread and never released, a leak outside a request) is gone, with no compatibility shim. Anyone needing a held raw lease calls lease_connection on their model directly.
  • The DB pack's tests now run against real Active Record on in-memory SQLite, so its Active Record calls are verified rather than mocked. activerecord and sqlite3 join activesupport as dev-only dependencies; the gem still declares no Rails runtime dependency.
  • BREAKING: shortcut now returns the Briefly::Shortcut it declares instead of the canonical name Symbol. Refine it in place — shortcut(:x) { ... }.memoize, .rescue_from(Error) { fallback }, in any order — so a shortcut's name is never written twice to annotate it. A bodiless shortcut(:x) fetches an already-declared shortcut (canonical or alias) to refine, raising Briefly::UnknownShortcutError on an unknown name; it never re-declares. A shortcut's memoization and its own error handlers live on the shortcut itself, so refining it after a redeclaration affects the declaration you named, exactly as its body does.
  • BREAKING: The top-level rescue_from(error_class) verb is now facade-wide only and takes no shortcut names; passing any raises ArgumentError pointing at shortcut(name).rescue_from(...). Scope a handler to a shortcut by chaining .rescue_from onto it. Global Briefly.rescue_from is unchanged.
  • BREAKING: the rescue-handler registry is now Briefly::Rescues (was Briefly::ErrorRegistry), reached through Briefly.rescues (was Briefly.errors) — it holds rescue_from handlers, not errors. Briefly.rescues.clear still resets globally registered handlers; the internal #wide enumerator is gone, replaced by #size for counting registrations.

Removed

  • BREAKING: App.reset! — use App.briefly.clear_memos!. It was a pure alias for clear_memos! with no internal callers.
  • BREAKING: The top-level memoize DSL verb — chain .memoize onto the shortcut shortcut returns (shortcut(:x) { ... }.memoize), or shortcut(:x).memoize for one declared elsewhere.
  • BREAKING: Scoping rescue_from by shortcut name on the top-level verb — both single-name rescue_from(Error, :x) and multi-name rescue_from(Error, :a, :b). Scope on the shortcut instead: shortcut(:x).rescue_from(Error) { ... }, chaining onto each of several.

v0.1.0 (2026-07-10)

Added

  • Briefly.define builds a facade of real, introspectable, stubbable methods — no method_missing.
  • shortcut(canonical, *aliases, &body) with argument, keyword and block forwarding; predicate and bang names; last-declaration-wins overrides. Each shortcut compiles to a real method carrying its body's arity and parameter kinds, with a source_location pointing at the block you declared — keyword names are exact, positionals get generated ones (__p0, __r1, …). A wrong-arity call, a missing required keyword and an unknown keyword raise ArgumentError at the call site, before any rescue_from handler is consulted.
  • namespace(name) { ... } — groups shortcuts behind a child facade, so App.db.query works without burning root-level names. Takes the whole DSL, including nested namespaces. clear_memos! cascades into it. configure stays atomic across the whole tree: a pass that raises anywhere leaves the root and every namespace untouched. A shortcut of the same name overrides a namespace and drops the child.
  • memoize — permanent per-process caching, correct for nil/false, never caching a rescued fallback.
  • rescue_from — facade-scoped, facade-wide and global (Briefly.rescue_from) handlers whose return value becomes the shortcut's value.
  • clear_memos! / reset!, configure, shortcuts, shortcut?, inspect.
  • Pack protocol: any object responding to #install(builder, **opts). use accepts keywords, forwarded to the pack's install. Briefly.register(name, pack) / Briefly.pack(name) provide a pack registry, so use "rails/db" resolves; values may be a pack or a constant path resolved on first use, and an unknown name raises Briefly::UnknownPackError.
  • Method fabrication — the arity, parameters and source_location each shortcut reports — is provided by candor, the sole runtime dependency (candor itself has none). Compiled bodies live under Candor::BODY_PREFIX; a shortcut may not take a name there.
  • Briefly::Rails — config/c, config_x/x, env and its predicates, root, cache, logger/log, credentials/cred, helpers/h, routes/r, renderer, render, plus a db namespace. Nothing in the pack is memoized. Its Config, Env and View groups are usable alone.
  • Briefly::Rails::DB — connection/conn, transaction/txn, query. query takes positional (query(sql, 1)) or named (query(sql, id: 1)) binds, and passes a bindless statement through unsanitized. Takes base: (default "ApplicationRecord"), resolved on every call so a reloaded class is never captured. Memoizes nothing and wires no lifecycle hook, so it works without a booted application.
  • Briefly::Rails::Reload — clears memos via Rails.application.reloader.to_prepare.
  • RBS signatures in sig/.
