dotenvpp-parser

Core .env file parser for DotenvPP.

This crate is no_std-compatible (with alloc) so it can be used in WASM and embedded environments. Enable the std feature (on by default) for std::error::Error implementations.

Features

• KEY=VALUE basic parsing with comment and blank-line handling
• Single-quoted values (literal, multiline supported), double-quoted values (with escapes), and unquoted values
• Multiline values in single-quoted and double-quoted strings
• export KEY=VALUE prefix support
• Escape sequences: \\, \", \n, \t, \r, \$
• Common unquoted escapes for spaces, quotes, dollar signs, and newlines

Example

use dotenvpp_parser::parse;

let input = "# Database config\nDB_HOST=localhost\nDB_PORT=5432\nSECRET='keep-it-safe'\n";

let pairs = parse(input).unwrap();
assert_eq!(pairs.len(), 3);
assert_eq!(pairs[0].key, "DB_HOST");
assert_eq!(pairs[0].value, "localhost");
