path

Path utilities.

Types

_None._

Functions

`join(foreign parts: Vec[String], r: Region) -> String`

Join path segments using the platform separator.

Parameters

foreign parts: Vec[String] - Path segments to join.
r: Region - Allocation region for the result.

Returns

Combined path string.

Notes

Empty segments are ignored.

---

`normalize(foreign path: String, r: Region) -> String`

Normalize a path lexically.

Parameters

path: String - Input path.
r: Region - Allocation region for the result.

Returns

Lexically normalized path.

Notes

Repeated separators and . components are removed.
.. components remove the preceding normal component when possible. Unresolved .. components are preserved in relative paths and discarded at an absolute root.
This function does not access the filesystem, resolve symlinks, expand home or environment references, or support Windows UNC and device paths.

---

`basename(foreign path: String, r: Region) -> String`

Return the last path component.

Parameters

foreign path: String - Input path.
r: Region - Allocation region for the result.

Returns

Last path component, or an empty string for root-like inputs.

---

`dirname(foreign path: String, r: Region) -> String`

Return the parent directory.

Parameters

foreign path: String - Input path.
r: Region - Allocation region for the result.

Returns

Parent directory path.

Notes

Root-like inputs are kept stable.
A path with no directory component returns ".".

---

`extname(foreign path: String, r: Region) -> String`

Return the extension of the last path component.

Parameters

foreign path: String - Input path.
r: Region - Allocation region for the result.

Returns

Extension text including the leading dot, or "" when no extension exists.

---

`is_absolute(path: String) -> bool`

Return whether path is absolute.

Parameters

path: String - Input path.

Returns

true if the path is absolute, otherwise false.

Notes

Windows paths accept both \ and / separators.
Drive-root forms such as C:\foo are treated as absolute.
