# CHANGELOG
## v1.0.2 (2026-05-17)
### 新特性
- **AutoForm**: 新增 `inline` 模式，支持紧凑的单行表单布局，并增强了与 `DataTable` 的联动能力（数据变化自动刷新）。
- **Resizer**:
- 支持 `$bind` 指令，实现尺寸的双向绑定。
- 新增 `resizing` 和 `change` 事件，便于监听实时与最终缩放结果。
### 优化
- **UI**:
- `Modal`, `Dialog`, `Toast` 默认主题色由 `body` 改为 `primary`，提升视觉引导。
- `Toast` 增加 `rounded` 圆角样式。
- 统一所有表单控件（input/select/textarea）在 `AutoForm` 中的设置默认为 `{}`。
- **FastList**: 重构虚拟滚动逻辑为独立的 `VirtualScroll` 模块，提升代码复用性与可维护性。
## v1.0.1 (2026-05-14)
- **Perf**: 优化 `FastList` 渲染逻辑，消除 Layout Thrashing，提升复杂列表（GroupedList/Tree）滚动性能达 10 倍以上。
- **Refactor**: 采用 `requestAnimationFrame` 优化初始化高度计算，减少闪烁。

# fsevents [![NPM](https://nodei.co/npm/fsevents.png)](https://nodei.co/npm/fsevents/)
Native access to MacOS FSEvents in [Node.js](https://nodejs.org/)
The FSEvents API in MacOS allows applications to register for notifications of
changes to a given directory tree. It is a very fast and lightweight alternative
to kqueue.
This is a low-level library. For a cross-platform file watching module that
uses fsevents, check out [Chokidar](https://github.com/paulmillr/chokidar).
## Installation
Supports only **Node.js v8.16 and higher**.
```sh
npm install fsevents
```
## Usage
```js
const fsevents = require('fsevents');
const stop = fsevents.watch(__dirname, (path, flags, id) => {
const info = fsevents.getInfo(path, flags, id);
}); // To start observation
stop(); // To end observation
```
The callback passed as the second parameter to `.watch` get's called whenever the operating system detects a
a change in the file system. It takes three arguments:
###### `fsevents.watch(dirname: string, (path: string, flags: number, id: string) => void): () => Promise<undefined>`
* `path: string` - the item in the filesystem that have been changed
* `flags: number` - a numeric value describing what the change was
* `id: string` - an unique-id identifying this specific event
Returns closer callback which when called returns a Promise resolving when the watcher process has been shut down.
###### `fsevents.getInfo(path: string, flags: number, id: string): FsEventInfo`
The `getInfo` function takes the `path`, `flags` and `id` arguments and converts those parameters into a structure
that is easier to digest to determine what the change was.
The `FsEventsInfo` has the following shape:
```js
/**
* @typedef {'created'|'modified'|'deleted'|'moved'|'root-changed'|'cloned'|'unknown'} FsEventsEvent
* @typedef {'file'|'directory'|'symlink'} FsEventsType
*/
{
"event": "created", // {FsEventsEvent}
"path": "file.txt",
"type": "file", // {FsEventsType}
"changes": {
"inode": true, // Had iNode Meta-Information changed
"finder": false, // Had Finder Meta-Data changed
"access": false, // Had access permissions changed
"xattrs": false // Had xAttributes changed
},
"flags": 0x100000000
}
```
## Changelog
- v2.3 supports Apple Silicon ARM CPUs
- v2 supports node 8.16+ and reduces package size massively
- v1.2.8 supports node 6+
- v1.2.7 supports node 4+
## Troubleshooting
- I'm getting `EBADPLATFORM` `Unsupported platform for fsevents` error.
- It's fine, nothing is broken. fsevents is macos-only. Other platforms are skipped. If you want to hide this warning, report a bug to NPM bugtracker asking them to hide ebadplatform warnings by default.
