ModCLI v0.4.0 – CLI Framework – Pre-Release

The ModCLI framework just leveled up.

Version v0.4.0 introduces a powerful set of features, cleaner architecture, and high-performance output controls for building modern CLI apps in Rust with zero bloat.

---

What's New in v0.4.0:

Advanced Output Rendering

• New output::build() system with:
  • Multi-style string builders (.bold(), .italic(), .underline(), etc.)
  • Background and foreground color control
  • Full support for ANSI-styled output
• Gradient support (2-color, 3-color, and multi-color)
• Styled .part() chaining with .get(), .print(), .copy(), .clear()

Enhanced CLI Table System

• Rewritten from scratch
• ANSI-aware alignment (styled content doesn't break layout)
• Supports Flex, Fixed(width), and Full terminal width modes
• Unicode themes: Ascii, Rounded, and Heavy
• Truncation and smart column sizing are built in

Enhanced Progress Bars

• Optional percentage, fill character, label color, and custom “done” message
• Auto + manual tick support
• Gradient fill-ready (optional)

Print Engine Revamp

• print::line(), print::write(), print::scroll(), print::loop() now control all CLI output
• Supports timed output and inline/scrolling modes

Hook System Update

• hook::deprecated() now tracks once-per-session deprecation warnings
• Hook functions mirror print types: info, warn, error, success, status, unknown

Theme + Color Management

• colors.rs: Named constants, lookup by name, and full color swatch
• themes.rs: Apply theme-wide defaults (foreground, background, log colors)

---

⚠️ Deprecated Modules

• color_picker.rs marked as deprecated
  → Replaced by colors::get(), colors::list(), and colors::print()

---

Notes

This is a pre-release intended for testing and CLI ecosystem integration.
Expect minor refactors and final stabilization before v1.0.0.
