This is a tiny library to generate file names.

It will give you unique file names based on current git commit, as well as the time and date. You can also set your own prefix and/or postfix.

When fn is called from the terminal, the file names look like this:

20160428-001056-597392-2d95c86-b775190
20160428-001056-153234-2d95c86-b775190

Which currently follows this format:

yyyymmdd-hhmmss-10^(-6)seconds-gitsha-proctimesha

Where gitsha is the prefix of the git commit sha. And proctimesha is a hash of the time when Fn() is called and the process id of the calling python script.

If you are not in a git repo, it looks like this:

20160428-001056-153234--b775190

If you use the package within python you can also:

• Pass your own prefix and postfix.
• Override the postfix.
• Append incremental numbers.
• Change the delimiter.
• Override the length of the git sha.

Se ./example.py for some usage

I have a lot of projects where I make large amounts of files (images, 3D models, 2D vector files), and I've always wanted a more efficient way of maintaining unique file names.

I got inspired to write this when I saw this tweet about how Vera Molar names her works in a Periscope video:

Install using (as sudo) either

./setup.py install

Or

./setup.py develop

The latter is most convenient if you will be editing the code.

No. It only uses the current time to make a relatively distinct string—don't use this for anything remotely important.
