Corex Generators + New Components

[karim-semmoud]

Summary

This PR introduces the first version of Corex generators and several improvements across the library.

---

Corex Generators

Adds project and code generators built on top of the Phoenix installer and mix phx.gen.* tasks.

mix corex.new

Extends mix phx.new with additional options to quickly scaffold a Phoenix + Corex application:

• --mode – adds light/dark mode switching using Corex.ToggleGroup
• --theme – adds theme switching using Corex.Select
• --lang – adds language switching
• --rtl – enables RTL support for selected languages
• --design – includes Corex design tokens and component CSS (optional)
• --designex – generates tokens using Designex, Style Dictionary, and Tokens Studio
• --a11y – adds accessibility testing (Wallaby + a11y_audit)
• --tidewave – includes Tidewave development tooling

The installer keeps Phoenix’s integration test approach to ensure generated apps compile, format, and pass tests in real usage.

mix corex.gen.html / mix corex.gen.live

Extensions of the Phoenix generators with built-in Corex component support.

Generated forms use Corex components such as:

• Select
• Checkbox
• PasswordInput
• DatePicker
• Native inputs for other types

They also respect project configuration (mode, theme, and languages).

---

New Components

The following components were added:

• Data Table (sorting + row selection)
• Data List
• Native Input (15+ types)
• Layout Heading
• Action
• Navigate
• Marquee
• Code

---

Unified Translations

Components that require accessible text now use a single translations attribute with English defaults and full Gettext support.

This removes the need to manually provide common accessibility labels while still allowing full customization.

---

Phoenix Stream Support

Corex components that accept item lists can now work directly with Phoenix Streams.

Lists update dynamically while preserving component state and accessibility behavior (for example keyboard focus).

Form components were also updated to resolve a controlled-mode issue related to ZagJS machine bindings.

---

Corex Design

Updated default themes demonstrate that any design token (not only colors) can vary per theme or mode, including spacing, border radius, and more.

Corex Design remains fully optional. All components are unstyled and can be used independently within existing design systems.

Upgrade Notes

Corex is still alpha. Some undocumented breaking changes may exist (for example attribute renames such as collection → items).

If you encounter issues during upgrade, feedback is welcome.
