ErlyDTL now has date and time formating

ErlyDTL, the Erlang version of the Django Template Language is progressing nicely. Most of the common tags and filters are implemented. Recently Colm Dougan joined the development team and added date and time formating.

Let's take a look at some examples with fictive dates:

Template: {% var1|date "r" %}
Rendered Output: Thu, 21 Dec 2000 16:01:07 +0200

Template: {% var2|date "jS F Y H:i" %}
Rendered Output: 27th February 2008 01:24

Template: It is the {% var3|date "jS o\f F Y" %}
Rendered Output: It is the 4th of September 2007

Django Template Language - the dojo implementation

Beside of Erlang based ErlyDTL (by Evan Miller and myself) there exists (at least) one other non-Python project which implements the Django Template Language: the dojo Javascript version: dojox DTL (documentation) for creating dynamically and template-based HTML layouts inside the Web browser (opposed to traditional approaches of creating HTML layouts at server-side). Today dojox DTL reached feature completeness, implementing all original Django tags and filters, at least that is what I guess from reading the SVN changes for the README:

--- This aims to be a 1:1 match with the Django Template Language as outlined in
+++ This is a 1:1 match with the Django Template Language as outlined in

While dojox DTL is a very interesting concept and brings new possibilities to separate client-side logic and presentation, I haven't seen yet a killer example. Maybe I just haven't looked far enough. But one thing is sure: if you use a template language at server side and at Javascript client side, and it can be the same template language, that's a huge benefit.

ErlyDTL - the Django template language in Erlang

I have been working on a new template language called ErlyDTL. Let's compare it first with the other, established players in the Erlang open source template languages field:

• ErlTL by Yariv Sadan. ErlTL is used in ErlyWeb and therefore probably the most popular Erlang template language. It exposes the full Erlang language to the template author, that is good, if the template author is an experienced Erlang developer, but bad, if the template author does not know Erlang. ErlTL compiles templates to beam files.
• sgte by Filippo Pacini. An Erlang implementation of StringTemplate. Enforces separation between model and view. Templates get evaluated at runtime. Used at erlware (if you install the erlware launcher, sgte is one of the core packages used internally for the various erlware templates)
• ErlyDTL by Evan Miller and myself: based on the Django template language. It does not expose Erlang to the template author, it compiles templates to beam files, pre-renders as much as possible at compilation time and supports a lot of features such as template inheritance, presetting variables at compilation time, automatic HTML escaping and lots of Django tags and filters. But it is not feature complete yet, just the more important tags and about half of the django filters are currently implemented.

If you wanna learn more about ErlyDTL, check out the code or take a look at the examples, there are a bunch of ErlyDTL demo and test templates at he googlecode project and also the resulting, rendered output files.

Update: There are more Erlang template engines out there: seethrough which is specifically for XML/XHTML and internally uses xmerl to do its magic. It is rather simple compared to the others, but depending on the use case that can be an advantage.
