temps 0.1

Context managers for creating and cleaning up temporary directories and files.

Latest Version: 0.3.0

## Introduction

`temps` is a python module containing context managers for creating and
cleaning up temporary files and directories.

This package is _alpha_ and its API is not stable.

Why do I never use the `tempfile` module?

- I am responsible for removing files and dirs tempfile creates, which creates
lots of boilerplate whenever I use it.
- There is no context manager for temp dirs.
- When using `mkstemp()`, I get an open file descriptor, not a file object,
that I have to close.
- The context manager for temp files contains statements like this
from the tempfile docs: "Whether the name can be used to open the file a
second time, while the named temporary file is still open, varies across
- I do not get to choose the file perms of files and dirs I create.

What do I like about this module?

- It has a context manager for creating a temp dir and another for temp files.
- The context manager cleans up the dir or file upon context exit, not upon file
- No ambiguity about whether you can or cannot open a file twice.
- You can set the permissions of the temp file or dir to what you want.
- It is very clear what the implementation is:
- directories are created and the path is returned.
- files are not created, since you'll want to do that in a `with
open(filename) ...` statement, and the path is returned.
- directories and files are cleaned up by the context managers.
- file and dir names are generated using the uuid module, which presumably
will avoid race conditions.

## Installation

### Install from

Download and install using pip:

pip install temps

### Install from

Using github, one can clone and install a specific version of the package:

cd ~
git clone

python install

## Usage

Creating a working dir for subprocesses:

with temps.tmpdir() as workdir:
with open(os.path.join(workdir, 'datafile'), 'wb') as fh:
fh.write(data)' {}'.format(workdir), shell=True)
with open(os.path.join(workdir, 'outfile')) as fh:

Creating a temp file for a transform and upload:

with temps.tmpfile() as transformed_path:
transform(input_path, transformed_path)
upload(transformed_path, destination)

The default values when parameters are not specified, are stored in variables
that are set using environment variables if available or a default value
otherwise. Here is a table listing the variable, the environment variable
checked, and the default value:
