*
* ```ts no-eval
* import { walkSync } from "@std/fs/walk";
*
* Array.from(walkSync(".", { includeDirs: false }));
* // [
* // {
* // path: "/Users/user/folder/script.ts",
* // name: "script.ts",
* // isFile: true,
* // isDirectory: false,
* // isSymlink: false
* // },
* // ]
* ```
*
* @example Exclude symbolic links
*
* Setting the `includeSymlinks` option to `false` will exclude symbolic links.
*
* File structure:
* ```
* folder
* ├── script.ts
* ├── foo
* └── link -> script.ts (symbolic link)
* ```
*
* ```ts no-eval
* import { walkSync } from "@std/fs/walk";
*
* Array.from(walkSync(".", { includeSymlinks: false }));
* // [
* // {
* // path: "/Users/user/folder",
* // name: "folder",
* // isFile: false,
* // isDirectory: true,
* // isSymlink: false
* // },
* // {
* // path: "/Users/user/folder/script.ts",
* // name: "script.ts",
* // isFile: true,
* // isDirectory: false,
* // isSymlink: false
* // },
* // ]
* ```
*
* @example Follow symbolic links
*
* Setting the `followSymlinks` option to `true` will follow symbolic links,
* affecting the `path` property of the walk entry.
*
* File structure:
* ```
* folder
* ├── script.ts
* └── link -> script.ts (symbolic link)
* ```
*
* ```ts no-eval
* import { walkSync } from "@std/fs/walk";
*
* Array.from(walkSync(".", { followSymlinks: true }));
* // [
* // {
* // path: "/Users/user/folder",
* // name: "folder",
* // isFile: false,
* // isDirectory: true,
* // isSymlink: false
* // },
* // {
* // path: "/Users/user/folder/script.ts",
* // name: "script.ts",
* // isFile: true,
* // isDirectory: false,
* // isSymlink: false
* // },
* // {
* // path: "/Users/user/folder/script.ts",
* // name: "link",
* // isFile: true,
* // isDirectory: false,
* // isSymlink: true
* // },
* // ]
* ```
*
* @example Canonicalize symbolic links
*
* Setting the `canonicalize` option to `false` will canonicalize the path of
* the followed symbolic link. Meaning, the `path` property of the walk entry
* will be the path of the symbolic link itself.
*
* File structure:
* ```
* folder
* ├── script.ts
* └── link -> script.ts (symbolic link)
* ```
*
* ```ts no-eval
* import { walkSync } from "@std/fs/walk";
*
* Array.from(walkSync(".", { followSymlinks: true, canonicalize: true }));
* // [
* // {
* // path: "/Users/user/folder",
* // name: "folder",
* // isFile: false,
* // isDirectory: true,
* // isSymlink: false
* // },
* // {
* // path: "/Users/user/folder/script.ts",
* // name: "script.ts",
* // isFile: true,
* // isDirectory: false,
* // isSymlink: false
* // },
* // {
* // path: "/Users/user/folder/link",
* // name: "link",
* // isFile: true,
* // isDirectory: false,
* // isSymlink: true
* // },
* // ]
* ```
*
* @example Filter by file extensions
*
* Setting the `exts` option to `[".ts"]` will only include entries with the
* `.ts` file extension.
*
* File structure:
* ```
* folder
* ├── script.ts
* └── foo.js
* ```
*
* ```ts no-eval
* import { walkSync } from "@std/fs/walk";
*
* Array.from(walkSync(".", { exts: [".ts"] }));
* // [
* // {
* // path: "/Users/user/folder/script.ts",
* // name: "script.ts",
* // isFile: true,
* // isDirectory: false,
* // isSymlink: false
* // },
* // ]
* ```
*
* @example Filter by regular expressions
*
* Setting the `match` option to `[/.s/]` will only include entries with the
* letter `s` in their name.
*
* File structure:
* ```
* folder
* ├── script.ts
* └── README.md
* ```
*
* ```ts no-eval
* import { walkSync } from "@std/fs/walk";
*
* Array.from(walkSync(".", { match: [/s/] }));
* // [
* // {
* // path: "/Users/user/folder/script.ts",
* // name: "script.ts",
* // isFile: true,
* // isDirectory: false,
* // isSymlink: false
* // },
* // ]
* ```
*
* @example Exclude by regular expressions
*
* Setting the `skip` option to `[/.s/]` will exclude entries with the letter
* `s` in their name.
*
* File structure:
* ```
* folder
* ├── script.ts
* └── README.md
* ```
*
* ```ts no-eval
* import { walkSync } from "@std/fs/walk";
*
* Array.from(walkSync(".", { skip: [/s/] }));
* // [
* // {
* // path: "/Users/user/folder/README.md",
* // name: "README.md",
* // isFile: true,
* // isDirectory: false,
* // isSymlink: false
* // },
