polymer-auto-import's Issues

Support for main page and demo pages

Support for pages which have <html> <head> tags. Right now we support only polymer elements.

Preserve existing attributes and save old imports.

Right now the script removes all existing imports and creates new.
Instead of this it is better to save all unused imports under special comment


Also if import already exists it is important to preserve all its attributes.

comment is duplicated after executing twice

subj

Import icons

Right now <iron-icon icon="menu"></iron-icon> is not resolved to import

<link rel="import" href="/components/iron-icons/iron-icons.html">

Should be:

all elements with atrribute name icon should be checked:
- if icon attribute value is not url and does not contain :, standard iron-icons should be imported
- if icon attribute value is a url -> ignore
- if icon attribute value has namespace separated with :, than specific icon set should be imported with the name of namespace.

Last element in behaviors array not resolved if comma stays after this element

Script can not resolve last value in array where comma stays after last element :

behaviors: [
                Polymer.NeonAnimationRunnerBehavior,
                Polymer.NeonAnimatableBehavior,
            ]

it tries to resolve to neon-animatable-behavior,

Preserve all other tags between import tags

Right now we take first and last import tag and remove everything between them including first and last tag. We should go smart and affect to only import tags.

Import behaviors

To import behaviors we can look at behaviors array and normalize last word from right.

For example Polymer.IronResizableBehavior should become IronResizableBehavior and then de-camelcased to iron-resizable-behavior.html for look up.

MyNamespace.Something.SomeBehavior to some-behavior.html.

Add 'test' folder to ignored folders

Right now iron-icon is resolved to bower_components/iron-icon/test/iron-icon.html.
We should avoid test folders.

Import animations

Currently animations are ignored.
What could be done:

look for entry-animation and exit-animation attributes.
look for animationConfig property

ReferenceError if polymer initialization snippet has `deep` calls

If a snippet has deep calls like this Something.Something or this.$.lalala -> we will get ReferenceError when polymer-auto-import will try eval it.

Make config path and/or root path as an arguments.

Optionally there should be ability to path rootPath (path to the root of the project) and config.json file path for configuration this way:
For second and third arguments should be this rule:
-If argument exists and is a directory, treat it as root path of the project.
-if argument exists and is .json file, treat it as config file.

Default config contains following properties:

{
    "rootDir": "",
    "bowerFolderName": "bower_components",
    "ignoredFolders": ["test", "demo"],
    "ignoredComponents": [],
    "attributes": [
        "effects",
        "entry-animation",
        "exit-animation"
    ],
    "resolve: {
        "iron-flex": "iron-flex-layout-classes",
        "iron-flex-reverse": "iron-flex-layout-classes",
        "iron-flex-alignment": "iron-flex-layout-classes",
        "iron-flex-factors": "iron-flex-layout-classes",
        "iron-positioning": "iron-flex-layout-classes"
    }
}

When property in custom config exists, default property should be overridden. No merge.

Throw error if polymer.json not found

If script can not find polymer.json it means it can not find root dir of the project which is critical, so a error should be thrown.

Polymer 3

hey! Are you still using this yourself? Would love it for Polymer 3, shouldn't be so different. The paths basically stayed the same, gotta use es6 imports now instead though. What do you think?
