# Changelog

All notable changes to this project will be documented in this file, in reverse chronological order by release.

## v0.10.0 2023-17-04

### Breaking Changes

- Changed VKCOM to laytan in imports and `go.mod`

### Added

- `ast.Type` enum and `ast.Vertex` `GetType() ast.Type` function for easily checking and storing vertex types
- Expose the internal lexer using `lexer.New(src []byte, config conf.Config) (Lexer, error)`

### Fixes

- Added some boundary checks in the formatter to prevent some panics
- A newline will now be added after a doc comment in the printer
- Some fixes for start and end column addition in previous release

## v0.9.0 2023-26-03

### Breaking Changes

- Dropped PHP 5 support to increase velocity/productivity

### Added

- Nodes and tokens now also contain their StartCol and EndCol
- 2 new interfaces for traversers (backwards compatible):
    - `traversers.CheckEntrance` interface: provides an `EnterNode(ast.Vertex) bool` that, when implemented, is called before entering a node, allowing short circuiting and more control over the traversal
    - `traversers.NotifyLeave` interface: provides an `LeaveNode(ast.Vertex)` that, when implemented, is called when a node has fully been traversed, again allowing for more control

### Fixes

- Fixed a bug where the parser would use token.DefaultBlockSize instead of position.DefaultBlockSize when instantiating the parser

### Internals

- Rely on code generations for several repeating/boilerplate tasks
- Refactors and deduplication after PHP 5 removal
- Add golangci-lint configuration and an editorconfig file
