treestamps 2.2.1

Create timestamp records for recursive operations on directory trees.

Treestamps

A library to set and retrieve timestamps to speed up operations run recursively on directory trees.

Documentation is pretty poor. Read the code for now.

Usage

Used in picopt and nudebomb. You can see how it's used in those projects.

    from pathlib import Path
    from treestamps import Grovestamps, GrovestampsConfig

    config = GrovestampsConfig(
        "MyProgramName",
        paths=("/foo", "/bar"),
        program_config={ "option_a": True, "option_b": False}
    )
    gs = Grovestamps(config)

    timestamp = gs[Path("/foo")].get()
    assert None == timestamp.get("file_relative_to_foo.txt")
    mtime = timestamp.set("file_relative_to_foo.txt")
    # mtime ~= now()
    # Also writes to `/foo/.MyProgramName_treestamps.wal.yaml`

    gs.dump()

Dumping removes /foo/.MyProgramName_treestamps.wal.yaml and writes to /foo/.MyProgramName_treestamps.yaml and /bar/.MyProgramName_treestamps.yaml

    # With similar config to above
    gs = Grovestamps(config)
    # Auto loads timestamps relevant to paths in config.

    timestamp_foo = gs[Path("/foo")].get()
    mtime_b = timestamp_foo.get("file_relative_to_foo.txt")
    mtime_a = timestamp_foo.get("another_file_relative_to_foo.txt")
    # mtime will be the time gs.dump() you called above.
    assert mtime_a == mtime_b

    timestamp_bar = gs[Path("/bar")].get()
    mtime_c = timestamp_foo.get("file_relative_to_bar.txt")
    assert mtime_c == mtime_a
