Serialization

env.zig can serialize configurations back to .env format.

Basic Serialization

const output = try env.serialize();
defer allocator.free(output);
// output: "KEY=value\nOTHER=foo\n"

Save to File

try env.save("output.env");

Serialization Options

Config Option	Default	Description
sort_keys	false	Sort keys alphabetically
quote_spaces	true	Quote values containing spaces
trailing_newline	true	Add a trailing newline
preserve_comments	false	Preserve original comments
indent	0	Indentation spaces

Sorted Keys

var env = env_mod.Env.init(allocator, .{ .sort_keys = true });
// Keys will be sorted alphabetically in output

Custom Quoting

Values with spaces, quotes, or special characters are automatically escaped:

try env.set("MESSAGE", "hello world");
const output = try env.serialize();
// MESSAGE="hello world"

Example Output

DATABASE_HOST=localhost
DATABASE_NAME=myapp
DATABASE_PORT=5432
LOG_LEVEL=info
