#### A DOM for making HTML with python 3! (and more)
### Install
```bash
python3 -m pip install domonic
# python3 -m pip install domonic --upgrade
```
## Creating HTML with Python 3
```python
from domonic.html import *
print(html(body(h1('Hello, World!'))))
#
Hello, World!
```
or to pretty format and insert the doctype, use an f-string:
```python
mydom = html(body(h1('Hello, World!'), a("somelink", _href="somepage.html")))
print(f"{mydom}")
```
```html
Hello, World!
somelink
```
### parsing html
Basic useage...
```bash
from domonic import domonic
mydom = domonic.parseString('
```
### rendering DOM objects
domonic is a pure python dom whos tree is composed of objects. i.e
```python
div()
#
```
cast str() on any element to render it without formatting.
```python
el = str(div())
print(el)
#
```
There's also a render method that takes 2 parameters, some domonic and an optional output file.
```python
page = div(span('Hello World'))
render(f"{page}", 'index.html') # notice use of f-string to pretty print the html
```
There's a few new rendering options. See DOMConfig.
```python
from domonic.dom import DOMConfig
print(DOMConfig.GLOBAL_AUTOESCAPE) # Default False
print(DOMConfig.RENDER_OPTIONAL_CLOSING_TAGS) # Default True
print(DOMConfig.RENDER_OPTIONAL_CLOSING_SLASH) # Defaults True
print(DOMConfig.SPACE_BEFORE_OPTIONAL_CLOSING_SLASH) # Default False
```
## DOM
DOM manipulation with python.
### createElement
to create your own elements use the DOM API
```python
from domonic.dom import *
site = html()
el = document.createElement('myelement')
site.appendChild(el)
print(site)
#
```
There's an evolving DOM API. To learn more about the webAPI [click here](https://developer.mozilla.org/en-US/docs/Web/API).
And check the [code/docs](https://domonic.readthedocs.io/) to see what's currently been implemented.
```python
mysite.querySelectorAll('button')
mysite.querySelectorAll("a[rel=nofollow]")
mysite.querySelectorAll("a[href='#services']")
mysite.querySelectorAll("a[href$='technology']")
mysite.querySelectorAll('.fa-twitter')
somelinks = mysite.querySelectorAll("a[href*='twitter']")
for l in somelinks:
print(l.href)
```
To use the DOM either reference your root 'html' node or import the dom modules global 'document'
```python
# access the document via the html tag
mydom = html()
# mydom.getElementbyID...
# or by importing the document global
from domonic.dom import document
# document.createElement...
print(document)
```
### javascript
There is a javascript package that mimics the js API:
```python
from domonic.javascript import Math
print(Math.random())
from domonic.javascript import Array
myArr=Array(1,2,3)
print(myArr.splice(1))
# [2, 3]
from domonic.javascript import URL
url = URL('https://somesite.com/blog/article-one#some-hash')
print(url.protocol) # https
print(url.host) # somesite.com
print(url.pathname) # /blog/article-one
print(url.hash) # #some-hash
# Use Global class to import all the js methods from the global namespace i.e
# from domonic.javascript import Global
# Global.decodeURIComponent(...
# Global.encodeComponent(...
# Global.setInterval(...
# from domonic.javascript import Date, String, Number
# etc..
```
Use setInterval and clearInterval with params
```python
from domonic.javascript import setInterval, clearInterval
x=0
def hi(inc):
global x
x = x+inc
print(x)
test = setInterval(hi, 1000, 2)
import time
time.sleep(5)
clearInterval(test)
print(f"Final value of x:{x}")
```
Or for a single delayed function call use setTimeout, clearTimeout
```python
from domonic.javascript import setTimeout, clearTimeout
timeoutID = setTimeout(hi, 1000)
```
You can call ```()``` on a stringvar to transform it into a Node
```python
from domonic.javascript import String
test = String("Hi there!")
test('div', _style="font-color:red;")
str(test('div', _style="font-color:red;"))
#
Hi there!
```
a-tags inherit URL:
```python
from domonic.html import *
atag = a(_href="https://somesite.com:8000/blog/article-one#some-hash")
print('href:', atag.href)
# href: https://somesite.com:8000/blog/article-one#some-hash
print('protocol:', atag.protocol)
# protocol: https:
print('port:', atag.port)
# port: 8000
atag.protocol = "http"
atag.port = 8983
print(atag)
#
```
For writing and using regular javascript, load from a src...
```python
script(_src="/docs/5.0/dist/js/bootstrap.bundle.min.js", _integrity="sha384-1234", _crossorigin="anonymous"),
#
```
or do inline js by opening triple quotes...
```python
script("""
let itbe = ""
"""),
```
### Styling
Styling is supported. Styles get passed to the style tag on render...
```python
mytag = div("hi", _id="test")
mytag.style.backgroundColor = "black"
mytag.style.fontSize = "12px"
print(mytag)
#
hi
```
To use css use a link tag as you usually would...
```python
link(_href="styles.css", _rel="stylesheet"),
```
or use triple quotes to open style tag...
```python
style("""
.placeholder-img {
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
}
"""),
```
### decorators
use decorators to wrap elements around function results
```python
from domonic.decorators import el
@el(html, True)
@el(body)
@el(div)
def test():
return 'hi!'
print(test())
#
hi!
# returns pyml objects so call str to render
assert str(test()) == '
hi!'
```
It returns the tag object by default. You can pass True as a second param to the decorator to return a rendered string instead. Also accepts strings as first param i.e. custom tags.
### data-tags
python doesn't allow hyphens in parameter names. so use variable keyword argument syntax for custom data-tags
```python
div("test", **{"_data-test":"test"} )
#
test
```
or for example a colon...
```python
t = div( **{"_:test":"something"} )
str(t)
#
```
### JSON (utils)
decorate any function that returns python objects to return json instead
```python
from domonic.decorators import as_json
import domonic.JSON as JSON
@as_json
def somefunc():
myObj = {"hi":[1,2,3]}
return myObj
print( somefunc() )
# {"hi":[1,2,3]}
print( JSON.is_json(somefunc()) )
# True
```
convert json arrays into html tables...
```python
import domonic.JSON as JSON
# i.e. containting flat json array of dicts... [{"id":"01","name": "some item"},{"id":"02","name": "some other item"}]
json_data = JSON.parse_file('somefile.json')
mytable = JSON.tablify(json_data)
print(mytable)
```
convert json arrays into csv files...
```python
import domonic.JSON as JSON
json_data = JSON.parse_file('somefile.json')
JSON.csvify(json_data, 'data.csv')
```
convert csv files to json...
```python
import domonic.JSON as JSON
json_data =JSON.csv2json("data.csv")
print(json_data)
```
more to come...
### SVG
All tags extend 'Element'. So will have DOM and magic methods available to them. See the [docs](https://domonic.readthedocs.io/).
```python
circ = svg(
circle(_cx="50", _cy="50", _r="40", _stroke="green", **{"_stroke-width": "4"}, _fill="yellow"),
_width="100", _height="100",
)
mysvg = svg()
mysvg.appendChild(circ / 10)
print(mysvg)
```
### Tweening
Tween values with the tween library:
```python
from domonic.lerpy.easing import *
from domonic.lerpy.tween import *
someObj = {'x':0,'y':0,'z':0}
twn = Tween( someObj, { 'x':10, 'y':5, 'z':3 }, 6, Linear.easeIn )
twn.start()
```
### aframe / x3d
3d tags can be used if you import the js
```python
from domonic.html import *
from domonic.xml.aframe import *
from domonic.CDN import *
_scene = scene(
box(_position="-1 0.5 -3", _rotation="0 45 0", _color="#4CC3D9"),
sphere(_position="0 1.25 -5", _radius="1.25", _color="#EF2D5E"),
cylinder(_position="1 0.75 -3", _radius="0.5", _height="1.5", _color="#FFC65D"),
plane(_position="0 0 -4", _rotation="-90 0 0", _width="4", _height="4", _color="#7BC8A4"),
sky(_color="#ECECEC")
)
_webpage = html(head(),body(
script(_src=CDN_JS.AFRAME_1_2), # < NOTICE you need to import aframe to use it
str(_scene)
)
)
render( _webpage, 'hello.html' )
```
### dQuery (NEW)
dQuery uses the º symbol (alt+0).
```python
from domonic.html import *
from domonic.dQuery import º
d = html(head(body(li(_class='things'), div(_id="test"))))
print( º('#test') )
#
print( º('.things') )
#
mydiv = º('')
#
b = º('#test').append(mydiv)
print(b)
#
```
Only recently started so check to see what's implemented.
### terminal
There is a command line package that can call bash/unix/posix and other apps on the command line:
This package only works on nix systems as it effectively just passes stuff off to subprocess.
```python
from domonic.terminal import *
print(ls())
print(ls("-al"))
print(ls("../"))
print(pwd())
print(mkdir('somedir'))
print(touch('somefile'))
print(git('status'))
for file in ls( "-al" ):
print("Line : ", file)
for f in ls():
try:
print(f)
print(cat(f))
except Exception as e:
pass
for i, l in enumerate(cat('LICENSE.txt')):
print(i,l)
print(man("ls"))
print(echo('test'))
print(df())
print(du())
for thing in du():
print(thing)
print(find('.'))
# print(ping('eventual.technology'))# < TODO - need to strean output
print(cowsay('moo'))
# print(wget('eventual.technology'))
print(date())
print(cal())
```
or just run arbitrary commands...
```python
from domonic.terminal import command
command.run("echo hi")
```
Take a look at the code in 'terminal.py' to see all the commands as there's loads. (Disclaimer: not all tested.)
Windows users can use now use cmd.
```python
from domonic.cmd import *
print(dir())
print(dir("..\\"))
```

### Join-In
Feel free to contribute if you find it useful. (I'd be grateful for help on all fronts)
Email me, message me directly if you like or create a discussion on here. Or join the [discord](https://discord.gg/a9pSZv4V5f).
If there are any methods you want that are missing or not complete yet or you think you can help make it better just update the code and send a pull request. I'll merge and releaese asap.
In the repo there's a requirements-dev.txt which is mostly the libs used in the examples.
requirements.txt are the libs used for packaging just the lib.
See also the CONTRIBUTING.md
### running examples
```bash
. venv/bin/activate
pip install -r requirements-dev.txt
cd examples
python lifecalendar.py
```
### run tests
There are tests used during dev. They are useful as code examples and to see what still needs doing.
See Makefile to run all tests:
```bash
make test # default tests ubuntu. so will fail on window when terminal test runs. comment out locally if that's the case
```
or to test a single function:
```bash
python -m unittest tests.test_javascript.TestCase.test_javascript_array
python -m unittest tests.test_dQuery.TestCase.test_addClass
python -m unittest tests.test_geom.TestCase.test_vec2
python3 -m unittest tests.test_cmd.TestCase.test_cmd_dir # only windows
```
or to test a whole module
```bash
python -m unittest tests.test_html
python -m unittest tests.test_CDN
```
to see coverage
```bash
coverage run -m unittest discover tests/
coverage report
```
or...
```bash
pip install pytest
pytest tests
```
### Disclaimer
There's several more widely supported libraries doing HTML generation, DOM reading/manipulation, terminal wrappers etc. Maybe use one of those for production due to strictness and support.
This is more of a fast prototyping library.
