volatile 0.2.dev1

A small extension for the tempfile module.

A replacement for tempfile.NamedTemporaryFile that does not delete the file on close(), but still unlinks it after the context manager ends.

• Mostly reuses the stdlib implementation, supporting the same signatures.

• Due to that, uses the OS’s built-in temporary file facilities, no custom schemes.

• Tested on Python 2.6+ and 3.3+

Usage

A typical use-case that is not possible with the regular NamedTemporaryFile:

import temp

with temp.file() as tmp:
    # tmp behaves like a regular NamedTemporaryFile here, except for that
    # it gets unlinked at the end of the context manager, instead of when
    # close() is called.

    tmp.close()

    # run the users $EDITOR
    run_editor(tmp.name)

    buf = open(tmp.name).read()

    # ...
