Re: vibe.d 0.7.12 released
Another one template engine that has pretty syntax is Razor in ASP.NET MVC. It's opensource and can be used in non-web areas. Although it would be good to read a simple tutorial "how to use/integrate 3rd party template engine with vibe.d".

Erb is like a Ruby preprocessor that can be used for any
format. It's used for many things in Ruby on Rails:
index.html.erb - Erb preprocessor, result is HTML
<% if foo %>
asd
<% end %>
bar.js.coffee.erb - Erb then CoffeeScript preprocessor, result
is JavaScript
<% if foo %>
bar = -> console.log("asd")
<% end %>
foo.text.erb - Erb preprocessor, result is plain text
<% if foo %>
asd
<% end %>
database.yml.erb - Erb preprocessor, result is YAML
development:
username: <%= username %>
password: <%= password %>
This really makes sense for D. It can be easily combined with D's
mixin capabilities to make it so you don't even need to implement
stuff like various loops:
<% [d code] %> -> [d code]
<%= [d expr] %> -> buffer.write([d expr]);
[text]-> buffer.write("[text]");

I personally also wanted to start a purely text based template system for a
while*, but never got
around to it, yet. My idea was to make something that is similar to the
existing template syntax, so
it feels more consistent (i.e. use #{expr} or !{expr} for inserting strings). I
also wanted to more
directly use D statements instead of special casing all of them, like the
Twig-likes do - which is a
lot of work and probably has higher memory requirements during compilation
(which is already often
at it's limit right now).
Of course, for people coming from Twig/Django it would be a big familiarity
advantage to provide the
same syntax, and existing templates could be reused. So that would be great to
have.
However, as soon as I really need it and nothing else exists yet, I will
probably implement a very
basic version of the former that can be extended later. Twig, from the first
looks, just seems like
much more involved than I can afford for this ATM.
* For HTML I very much prefer to have all the syntax overhead of HTML taken
off. It's faster to type
and more readable (more readable also because it's possible to leave blank
lines to structure the
code without having them appear in the output). But of course this is a topic
of personal
taste/preference.

I'm thinking about something similar to this, syntax-wise: > http://jinja.pocoo.org/ I admit I'm not a fan of Jade either. Indent-syntaxes just aren't my thing. And fixing the larger semantic issues I have with HTML/CSS isn't part of Jade's charter, AFAICT. (That said, I don't have any problem with it being in Vibe.d.) Personally, I just use Adam's HTML DOM for D: https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff I've built up a couple utility libs that use the DOM to help automate some stuff (defining a page, caching rendered pages, repeating elements on a page, building/validating forms). It's mostly independent of Vibe.d, but I do use it with Vibe.d. I've been planning to release those utility libs when they're a little bit more ready (they're still a little too closely integrated into a private project of mine, and they still need some more work).

You can have a nice HTTP server in Python in 0 lines of code, by running: python -m SimpleHTTPServer :) Issues about Python GIL are irrelevant (even if true) as people just use process pools via multiprocessing or concurrent.futures. Exactly, for example spawn a few processes with uWSGI and the Python script doesn't have to deal with multithreading or even use greenlets. So in most of the cases there is no GIL issue... unless you really need multithreading for a fast web service keeping internal states and locks, entering a no-python land.

Once you have those things covered, you can win people over by playing to the performance tune. They love that. Of course having a big traffic site using it would help a lot.

The "aware of typos in your code even before running your program" is
definitely a direct Python vs D thing. And it's a huge deal, IMO (And
yea, I'm saying that after having [tried to] use Python/Bottle).

While I agree that Vibe.d vs Flask/DJango/etc is the bigger comparison
here, I think GIL is still relevant: With the Python-based
stuff (as far as I'm aware), it's something that has to be actively
worked around. When I tried to use Python/Bottle, I didn't even *know*
how to do that ('Course, I'm not super-experienced with Python - and
hope to never be - but still.) With D/Vibe.d, OTOH, GIL is simply
a non-issue period.
