tmuxp.workspace.builder.prepended_sys_path

Temporarily prepend directories to sys.path, restoring it on exit.

Paths are prepended in order (first entry ends up at sys.path[0]). An empty or falsy paths is a no-op. Uses only literal directory entries; it avoids site.addsitedir (which runs .pth startup code).

Examples

>>> import sys
>>> ext = tmp_path / "ext"
>>> ext.mkdir()
>>> before = list(sys.path)
>>> with prepended_sys_path([ext]):
...     sys.path[0] == str(ext)
True
>>> sys.path == before
True

Parameters

• paths ( list[pathlib.Path] | None ) – directories to prepend
