# How does it work?
`elm-lint` turns the code of the analyzed file into an [Abstract Syntax Tree (AST)](https://en.wikipedia.org/wiki/Abstract_syntax_tree)
using the [`elm-syntax` package](https://package.elm-lang.org/packages/stil4m/elm-syntax/latest/).
An AST is a tree-like structure which represents your source code.
Then, `elm-lint` will traverse the nodes in the AST in the following order, and
call the visitor function associated to the type of node:
(a tree-like structure which represents your source code) using the
[`elm-syntax` package](https://package.elm-lang.org/packages/stil4m/elm-syntax/latest/).
Then, for each file and rule, it will give the details of your project (like the `elm.json` file) and the
contents of the file to analyze to the rule. The order in which things get passed to the rule is the following:
- The `elm.json` file, visited by [`withElmJsonVisitor`](#withElmJsonVisitor) (can only collect data)
- Read project-related info (only collect data in these steps)
- The `elm.json` file, visited by [`withElmJsonVisitor`](#withElmJsonVisitor)
- Visit the file (in the following order)
- The module definition, visited by [`withSimpleModuleDefinitionVisitor`](#withSimpleModuleDefinitionVisitor) and [`withModuleDefinitionVisitor`](#withModuleDefinitionVisitor)
- Each import statement, visited by [`withSimpleImportVisitor`](#withSimpleImportVisitor) and [`withImportVisitor`](#withImportVisitor)
- Each declaration statement, visited by [`withSimpleDeclarationVisitor`](#withSimpleDeclarationVisitor) and [`withDeclarationVisitor`](#withDeclarationVisitor).
