Jinja
|
|
=====
|
|
|
|
Jinja is a fast, expressive, extensible templating engine. Special
|
|
placeholders in the template allow writing code similar to Python
|
|
syntax. Then the template is passed data to render the final document.
|
|
|
|
It includes:
|
|
|
|
- Template inheritance and inclusion.
|
|
- Define and import macros within templates.
|
|
- HTML templates can use autoescaping to prevent XSS from untrusted
|
|
user input.
|
|
- A sandboxed environment can safely render untrusted templates.
|
|
- AsyncIO support for generating templates and calling async
|
|
functions.
|
|
- I18N support with Babel.
|
|
- Templates are compiled to optimized Python code just-in-time and
|
|
cached, or can be compiled ahead-of-time.
|
|
- Exceptions point to the correct line in templates to make debugging
|
|
easier.
|
|
- Extensible filters, tests, functions, and even syntax.
|
|
|
|
Jinja's philosophy is that while application logic belongs in Python if
|
|
possible, it shouldn't make the template designer's job difficult by
|
|
restricting functionality too much.
