Crate env_sync 

Environment file synchronization library.

This library provides functionality to parse .env files while preserving comments and synchronize them with template files. It’s designed for scenarios where you want to maintain a template structure while preserving local customizations.

Features

• Zero-copy parsing: Uses Cow<str> for efficient string handling
• Comment preservation: Maintains both preceding and inline comments
• Flexible synchronization: Merges template structure with local values
• Optional tracing: Detailed logging when the tracing feature is enabled

Example

use env_sync::sync::{EnvSync, EnvSyncOptions};
use std::path::PathBuf;

let options = EnvSyncOptions {
    local_file: None, // defaults to .env
    template_file: PathBuf::from(".env.template"),
};

EnvSync::sync_with_options(options).unwrap();
