[ANN] euuid 1.0.0 - an erlang UUID implementation

[Martijn Rijkeboer]

Hello,

As an exercise for learning Erlang I wrote an Universally Unique
IDentifier (UUID) implementation as defined in RFC 4122. This module
implements the UUID versions 1, 3, 4 and 5. It also implements a custom
time based UUID that is based on version 1 but has a different layout to
allow easy sorting on the creation date. This module is available as
open-source under the MIT licence for anyone to use.

You can take a look at the code on my github repository:
- https://github.com/mrijkeboer/euuid

Since this is my first Erlang program please let me know what you think.
I'm open to suggestions and enhancements.

Best regards,


Martijn Rijkeboer

There is simpler/faster code that serves the same purpose (rfc uuids, versions 1,3,4,5) under a similar license (BSD) here:
https://github.com/okeuday/uuid

Getting the real MAC address is possible in Erlang, though undocumented.  I include the Erlang pid integers within the node id for version 1 UUIDs and keep the version 1 state cacheable for quicker usage.

Hello Martijn,

Well, UUIDs seem to be:

1. A good exercise
2. Implemented over and over again (I'll just quote mine, but a good way to
check your code would be to have a look on older implementations)
3. A good candidate for inclusion somewhere in a library upstream :)

My (own and old) 2 cents

Best regards,

I wonder, at least two to three times a week, why foobar module isn't
a part of the OTP distribution.

Admittedly, I'm not sure how that happens.

Off the top of my head, a few things that I hate looking elsewhere for:

gproc, json, bin_to_hex, uuid, urllib (URL utils ala mochiweb_util), getopt

Is there a formal procedure to submit new modules to OTP? I am the author of one implementation of getopt that some people are using and I'd like to submit it to be included in OTP. Are there any conditions that have to be met besides those of licensing and how useful it is?

Do you still have your uuid code accessible somewhere?

The website was moved to biniou.net: http://erlang.biniou.net/erluuid/

Things to note: this code is *very* old, it was written as a port-driver before
NIFs were added, to learn how to write drivers. It might not be perfect.

Also, there has been at least 3 or 4 other implementations of UUIDs since,
in other projects, which may be of better quality/completeness

https://github.com/okeuday/uuid -as Zabrane mentioned- seems quite good

So I just put my version back online for reference :)

Historical reference, I meant. Mine is definitely outdated/not the
best available :)
