* Jinja Templating for JavaScript v0.1.8
|
|
||||||
* https://github.com/sstur/jinja-js
|
|
||||||
*
|
|
||||||
* This is a slimmed-down Jinja2 implementation [http://jinja.pocoo.org/]
|
|
||||||
*
|
|
||||||
* In the interest of simplicity, it deviates from Jinja2 as follows:
|
|
||||||
* - Line statements, cycle, super, macro tags and block nesting are not implemented
|
|
||||||
* - auto escapes html by default (the filter is "html" not "e")
|
|
||||||
* - Only "html" and "safe" filters are built in
|
|
||||||
* - Filters are not valid in expressions; `foo|length > 1` is not valid
|
|
||||||
* - Expression Tests (`if num is odd`) not implemented (`is` translates to `==` and `isnot` to `!=`)
|
|
||||||
*
|
|
||||||
* Notes:
|
|
||||||
* - if property is not found, but method '_get' exists, it will be called with the property name (and cached)
|
|
||||||
* - `{% for n in obj %}` iterates the object's keys; get the value with `{% for n in obj %}{{ obj[n] }}{% endfor %}`
|
|
||||||
* - subscript notation `a[0]` takes literals or simple variables but not `a[item.key]`
|
|
||||||
* - `.2` is not a valid number literal; use `0.2`
|
|
||||||
