cenv-rs

cenv-rs is a Rust-based Terminal User Interface (TUI) tool designed to help developers interactively generate .env files from .env.example templates. With a focus on speed and usability, it features Vim-like keybindings and out-of-the-box support for theming, defaulting to the Catppuccin Mocha palette.

Features

• Parse .env.example files to extract keys, default values, and comments.
• Vim-like keybindings for quick navigation and editing.
• Built-in theming support with Catppuccin Mocha as the default.
• Configurable through a standard TOML file.

Ensure you have Rust and Cargo installed, then run:

cargo install --path .

Alternatively, you can build from source:

git clone <repository_url>
