# Changelog

This file documents any relevant changes done to ViUR html5 since version 2.

## 3.0.0 [develop]

This is the current development version.

- Feature: Ported framework to Python 3 using [Pyodide](https://github.com/iodide-project/pyodide), with a full source code and library cleanup
- Feature: `html5.Widget.__init__()` now allows parameters equal to `Widget.appendChild()` to directly stack widgets together.
Additionally, the following parameters are available:
- `appendTo`: Directly append the newly created widget to another widget.
- `style`: Provide class attributes for styling added to the new Widget, using `Widget.addClass()`.
- Feature: `html5.Widget.appendChild()` and `html5.Widget.prependChild()` can handle arbitrary input now, including HTML, lists of widgets or just text, in any order. `html5.Widget.insertChild()` runs slightly different, but shares same features. This change mostly supersedes `html5.Widget.fromHTML()`.
- Feature: New `replace`-parameter for `html5.Widget.appendChild()` and `html5.Widget.prependChild()` which clears the content.
- Feature: `html5.ext.InputDialog` refactored & disables OK-Button when no value is present.
- Feature: `html5.utils.doesEventHitWidgetOrChildren()` and `html5.utils.doesEventHitWidgetOrParent()` now return the Widget or None instead of a boolean, to avoid creating loops and directly work with the recognized Widget.
- Feature: New function `html5.Widget.onBind()` enables widgets to react when bound to other widgets using the HTML parser.
- Feature: Replace HTML-parsing-related `vars`-parameter generally by `**kwargs`, with backward-compatibility.
- Speed-improvement: Hold static `_WidgetClassWrapper` per `html5.Widget` instead of creating one each time on the fly.

## [2.5.0] Vesuv

Release date: Jul 26, 2019

- Bugfix: `Widget.Th()` now supporting full col-/rowspan getting and setting.
- Bugfix: HTML-parser accepts tags in upper-/camel-case order now.
- Bugfix: HTML-parser handles table tags with tbody/thead tags inside more gracefully.
- Feature: Split HTML-parser into separate stages to compile and run; This allows to pre-compile HTML into a list/dict-structure and render it later on without parsing it again. `parseHTML()` is the new function, `fromHTML()` works like before and handles pre-compiled or raw HTML as parameter.
- Feature: `fromHTML()` extended to `vars` parameter to replace key-value pairs in text-nodes and attribute values expressed as `{{key}}`.
- Feature: HTML-parser dynamically reconizes void elements
- Feature: `html5.registerTag()` can be used to define new or override existing HTML elements in the HTML parser by custom implementations based on `html5.Widget()`
- Feature: New function `Widget.isVisible()` as counterpart for `Widget.isHidden()`.

## [2.4.0] Agung

Release date: May 17, 2019

- Bugfix: Fixed bug with disabling of input widgets.
- Feature: Fully refactored the librarys source base into just two single files, to reduce number of required files to download and make the library easier to access.
- Feature: New function `Widget.isHidden()` to check if a widget is currently shown.
- Feature: Improved handling of key-events.
- Feature: Allow to close popups by pressing `ESC`.
- Feature: Improvements for SVG and TextNode.

## [2.3.0] Kilauea

Release date: Oct 2, 2018

- Refactored `html5.ext.SelectDialog`
- Extended html parser to apply data-attributes
- Switching event handling to newer JavaScript event listener API
- Added `onFocusIn` and `onFocusOut` events

## [2.2.0] Etna

Release date: Apr 23, 2018

- Implemented `html5.Head()` to access the document's head object within the library.
- Directly append text in construction of Li().

## [2.1.0]

Release date: Nov 2, 2017

- Introduced a build-in HTML parser (`Widget.fromHTML()`) that is capable to compile HTML-code into DOM-objects of the html5 library, and an extra-feature to bind them to their root node for further access. This attempt makes it possible to create PyJS apps using the HTML5 library without creating every single element by hand.
- A more distinct way for `Widget.hide()` and `Widget.show()` that cannot be overridden by styling. (setting "hidden" does not work when another display value is set).
- Utility functions `Widget.enable() and `Widget.disable()`.
- Directly append text in construction of Div() and Span().
- Allow for tuple and list processing in table cell assignments.
- Adding `utils.parseFloat()` and `utils.parseInt()` utility functions.
- Implemented `colspan` attribute for Th()
- New README.md and CHANGELOG.md.

## 2.0

Release date: Dec 22, 2016

- v[2.0.1]: Directly append text in construction of Option().
- v[2.0.1]: Anything added to Widget.appendChild() or Widget.prependChild() which is not a widget is handled as text (TextNode() is automatically created).
- New functions `Widget.prependChild()`, `Widget.insertBefore()`, `Widget.children()`, `Widget.removeAllChildren()`,
`Widget.addClass()`, `Widget.removeClass()`, `Widget.toggleClass()`
- Utility functions `utils.doesEventHitWidgetOrParents()`, `utils.doesEventHitWidgetOrChildren()` taken from vi77
- Insert text blocks easier with `utils.textToHtml()`
- Several bugfixes

GNU LESSER GENERAL PUBLIC LICENSE
Version 3, 29 June 2007

Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.


This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.

0. Additional Definitions.

As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.

"The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.

An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.

A "Combined Work" is a work produced by combining or linking an
Application with the Library. The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".

The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.

The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.

1. Exception to Section 3 of the GNU GPL.

You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.

2. Conveying Modified Versions.

If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:

a) under this License, provided that you make a good faith effort to
ensure that, in the event an Application does not supply the
function or data, the facility still operates, and performs
whatever part of its purpose remains meaningful, or

b) under the GNU GPL, with none of the additional permissions of
this License applicable to that copy.

3. Object Code Incorporating Material from Library Header Files.

The object code form of an Application may incorporate material from
a header file that is part of the Library. You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:

a) Give prominent notice with each copy of the object code that the
Library is used in it and that the Library and its use are
covered by this License.

b) Accompany the object code with a copy of the GNU GPL and this license
document.

4. Combined Works.

You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:

a) Give prominent notice with each copy of the Combined Work that
the Library is used in it and that the Library and its use are
covered by this License.

b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.

c) For a Combined Work that displays copyright notices during
execution, include the copyright notice for the Library among
these notices, as well as a reference directing the user to the
copies of the GNU GPL and this license document.

d) Do one of the following:

0) Convey the Minimal Corresponding Source under the terms of this
License, and the Corresponding Application Code in a form
suitable for, and under terms that permit, the user to
recombine or relink the Application with a modified version of
the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying
Corresponding Source.

1) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (a) uses at run time
a copy of the Library already present on the user's computer
system, and (b) will operate properly with a modified version
of the Library that is interface-compatible with the Linked
Version.

e) Provide Installation Information, but only if you would otherwise
be required to provide such information under section 6 of the
GNU GPL, and only to the extent that such information is
necessary to install and execute a modified version of the
Combined Work produced by recombining or relinking the
Application with a modified version of the Linked Version. (If
you use option 4d0, the Installation Information must accompany
the Minimal Corresponding Source and Corresponding Application
Code. If you use option 4d1, you must provide the Installation
Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)

5. Combined Libraries.

You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:

a) Accompany the combined library with a copy of the same work based
on the Library, uncombined with any other library facilities,
conveyed under the terms of this License.

b) Give prominent notice with the combined library that part of it
is a work based on the Library, and explaining where to find the
accompanying uncombined form of the same work.

6. Revised Versions of the GNU Lesser General Public License.

The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.

If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.

# ViUR html5

**html5** is a DOM-abstraction layer and API that is used to create client-side Web-Apps running in the browser and written in Python.

Look [here](https://www.viur.dev/blog/html5-library) for a short introduction.

## About

This API and framework is used to implement HTML5 web-apps using the Python programming language. The framework is an abstraction layer for a DOM running in [Pyodide](https://github.com/iodide-project/pyodide), a Python 3 interpreter compiled to web-assembly.

It provides

- class abstraction for all HTML5-DOM-elements, e.g. `html5.Div()`
- a built-in HTML parser and executor to generate DOM objects from HTML-code
- helpers for adding/removing classes, arrange children, handling events etc.

The most prominent software completely established on this library is [ViUR-vi](https://github.com/viur-framework/viur-vi/), the visual administration interface for ViUR-based applications.

[ViUR](https://www.viur.dev) is a free software development framework for the [Google App Engine](https://appengine.google.com).

## Quick Start

**Warning: This section is incomplete, a working example will follow soon!**

```python
import html5

class Game(html5.Div):
def __init__(self):
super().__init__(
"""
<label>
Your Name:
<input [name]="myInput" type="text" placeholder="Name">
</label>
<h1>Hello <span [name]="mySpan" class="name">Enter Name</span>!</h1>
""")
self.sinkEvent("onChange")

def onChange(self, event):
if html5.utils.doesEventHitWidgetOrChildren(event, self.myInput):
self.mySpan.appendChild(self.myInput["value"], replace=True)

Game()
```
