# Structure

The Cheddar source code is located in the `src/` directory.

## Tokenizer

The tokenizer has no specific folder structure. Terminal parsers, are generally kept in the `literals/` directory, expression non-terminals in the `parsers/`, and statements in the `states/` directory.

## Standard Library

The file structure of STDLIB (the standard library) is simple. It's located in the `src/stdlib/` directory. In this root directory, you'll see two files: `api.es6` and `stdlib.es6`. Each of these have their own uses:

* `stdlib.es6`: This constructs the global scope (i.e. the standard library). 
* `api.es6`: This is the API itself, it defines useful functions and provides the Cheddar primitives (`CheddarString`, `CheddarNumber`, etc.) to you. This also helps avoid cyclic dependency errors.

Here's a diagram of the further folder structure

```
stdlib/
 |
 |-- stdlib.es6      Standard Library List
 |-- api.es6         The STDLIB API
 |
 |-- ns/             Namespaces
 |    |- <name>/       The implementations
 |    |- <name>.es6    Compiles the namespace's properties/methods
 |
 |-- primitive/      Primitive Libraries
      |- <name>/       A specific primitive
          |- lib/        The implementations
          |- lib.es6      Compiles the methods/properties
          |- static.es6   The static properties
```

`<name>` would be replaced with the name of that specific item.

If you which to create a new namespace, or a global class. Create a `<name>.es6` file in `ns/` and a folder in the same directory. `<name>.es6` will be where your class/namespace is defined. Individual method implementations can go in the folder you created. For example, if I was creating a package named "Geometry" my files/folders would look like:

```
stdlib/ns/
 |-- geometry.es6
 |-- geometry/
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.cheddar.vihan.org/docs/developing/structure.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
