Traditional web frameworks comprise of an ORM layer over a DB, a templating engine and some | ||
HTTP dispatcher and session management. In my view, the first two are relics of the past and | ||
we can (and should) do without them, and the third should be greatly improved. Luckily, modern | ||
minimalist frameworks like ``flask`` get us closer to that, but there's still way to go. | ||

The Vision: Snakes all the Way Down! | ||

on the fly. JSON API calls everywhere, by default. | ||
* Templating is a stupid thing: it's basically very limited, cumbersome, and impossible-to-debug | ||
form of function application. A template takes parameters and generates HTML: it's a function! | ||
* An HTTP server is ultimately a degenerate form of Remote Procedure Call (RPC) - it dispatches | ||
function names (URLs) to concrete functions, extracts parameters, and generally alleviates | ||
your code from the mess that is HTTP. It's time to realize it and think about it the way it | ||

realy is. | ||
* HTML is too low-level for us to mess with; we ought to be talking at a much more semantic | ||
level, that renders itself as HTML plus the required JavaScript. | ||
* JavaScript is a horrible language and we should strive to avoid any contact with it. We do this | ||
* JavaScript is a horrible language and we should strive to avoid any contact with it. We do this | ||
by putting as much of it as possible into the framework. Semantic elements may generate their | ||
appropriate JavaScript when they render themselves to HTML, but the product should be pure. | ||
* ORM and SQL suck. A document-oriented database (e.g., *mongo*) would normally prove the better | ||
choice (unless you need really complex queries): if you choose to work in a dynamic language, | ||
why would you work with a static DB schema? | ||

Web programming involves too many unrelated technologies that were stacked one on top of the other | ||
over the years (HTTP, HTML, JavaScript/CoffeeScript, CSS/Sass, JSON, AJAX, SQL, templating, CGI, | ||
...). The purpose of minima is to reduce that mess to pure Python, as far down as we can go, | ||

||
### Install | ||
``` | ||
$ pip install minima | ||
``` | ||
|
||
### Useage | ||
#### Hypertext | ||
Write 'HTML Functions' using a simple **DSL** within Python. Add elements and classes using dot notation. Create nested elements using `with`. | ||
|
||
``` | ||
>>> import minima.hypertext as H | ||
>>> print H.h1("Welcome", class_="highlight", id="foo") | ||
<h1 class="highlight" id="foo">Welcome</h1> | ||
>>> print H.h1.highlight("Welcome", id="foo") | ||
<h1 class="highlight" id="foo">Welcome</h1> | ||
>>> print H.div.content(h1.highlight("Welcome"), "This is my page") | ||
<div class="content"> | ||
<h1 class="highlight">Welcome</h1> | ||
This is my page | ||
</div> | ||
>>> with div.content: | ||
... h1.highlight("Welcome") | ||
... TEXT("This is my page") | ||
... | ||
<div class="content"> | ||
<h1 class="highlight">Welcome</h1> | ||
This is my page | ||
</div> | ||
``` |
