declare_vars(v)	Yields the Javascript lines that declare the given Variable v.
dict2js(d)
id2js(s)
js_line(s, *args)
obj2dict(o, attrs)
py2js(v[, compact])	Note that None values are rendered as null (not undefined).
register_converter(func)

Classes

Component([name])	A Component is a Variable whose value is a dict of options.
Value(value)
Variable(name, value)
VisibleComponent(name, **kwargs)	A visible component
js_code(s)	A string that py2js will represent as is, not between quotes.

lino.utils.jsgen.obj2dict(o, attrs)

Parameters:

• o – object

• attrs – space seperated string or list of strings of wanted attrs

• kws – existing dict of values

Returns:

dict with key:value pairs that match the object[arrts] if arrts exist in object

class lino.utils.jsgen.js_code(s)

Bases: object

A string that py2js will represent as is, not between quotes.

class lino.utils.jsgen.Component(name=None, **options)

Bases: Variable

A Component is a Variable whose value is a dict of options. Deserves more documentation.

walk()

Walk over this component and its children.

class lino.utils.jsgen.VisibleComponent(name, **kwargs)

Bases: Component, Permittable

A visible component

install_permission_handler()

Define the allow_read handler used by get_view_permission(). This must be done only once, but after having configured debug_permissions and required_roles.

lino.utils.jsgen.declare_vars(v)

Yields the Javascript lines that declare the given Variable v. If v is a Component, list, tuple or dict which contains other variables, recursively yields also the lines to declare these.

lino.utils.jsgen.py2js(v, compact=True)

Note that None values are rendered as null (not undefined).
