Path manipulation library

Project description

betterpath, or “bp”, is an adaptation of the classic Twisted FilePath type and interface. bp provides a simple, robust, well-tested object abstraction over file paths, generalizing the concept of file paths beyond filesystems.

File Paths

bp exposes an interface, bp.abstract.IFilePath, for file paths, and provides the following concrete implementations:

  • bp.filepath.FilePath, for the root filesystem
  • bp.zippath.ZipPath, for ZIP archives
  • bp.memory.MemoryPath, for in-memory temporary filesystems

Examples

Saving Data to Disk

The Old Way

def save(base, fragments, data):
    # Unsafe either way; what if `fragments` contains ".."?
    path = os.path.join(os.path.abspath(base), os.sep.join(fragments))
    # path = os.path.join(os.path.abspath(base), *fragments)
    # I hope that this doesn't fail mid-write! Also, did the directories
    # exist? I think so, yes.
    with open(path, "wb") as handle:
        handle.write(data)

The New Way

def save(base, fragments, data):
    path = base.descendant(fragments)
    path.parent().makeDirs()
    path.setContent(data)
