cooklang-rs

Cooklang parser in rust with opt-in extensions.

All regular cooklang files parse as the same recipe, the extensions are a superset of the original cooklang format. Also, the extensions can be turned off, so the parser can be used for regular cooklang if you don't like them.

You can see a detailed list of all extensions explained here.

The parser also includes:

• Rich error report with annotated code spans. (like this one)
• Unit conversion.
• Recipe scaling.
• A parser for cooklang aisle configuration file.

lib.rs:

A cooklang parser with opt-in extensions.

The extensions create a superset of the original cooklang language and can be turned off. To see a detailed list go to extensions.

Also includes:

• Rich error report with annotated code spans.
• Unit conversion.
• Recipe scaling.
• A parser for cooklang aisle configuration file.

Basic usage

If you just want to parse a single cooklang file, see parse.

As soon as you are going to parse more than one, or want to change the configuration of the parser, construct a parser instance yourself.

To construct a parser use CooklangParser::new or CooklangParser::default if you want to configure the parser. You can configure which Extensions are enabled and the Converter used to convert and check units.

// Create a parser
// (this is the default configuration)
let parser = CooklangParser::new(Extensions::all(), Converter::default());

Then use the parser:

let src = "This is an @example.";
let name = "Example Recipe";
let (recipe, _warnings) = parser.parse(src, name).into_result()?;
assert_eq!(recipe.name, name);
assert_eq!(recipe.ingredients.len(), 1);
assert_eq!(recipe.ingredients[0].name, "example");

Recipes can be scaled and converted. But the following applies:

• Parsing returns a ScalableRecipe.

• Only ScalableRecipe can be scaled or default_scaled only once to obtain a ScaledRecipe.

• Only ScaledRecipe can be converted. This lib has 2 features, both enabled by default:

• bundled_units. Includes a units file with the most common units for recipes in English. These units are available to load when you want without the need to read a file. The default Converter use them if this feature is enabled. This is the bundled file

• aisle. Enables the aisle module.
