Generate html with python 3! (and much more)
• html : Generate html with python 3 😎
• dom : DOM API in python 3 😲
• javascript : js API in python 3 😳
• terminal : call terminal commands with python3 😱 (see at the end)
• JSON : utils for loading / decorating / transforming
• SVG : Generate svg using python (untested)
• aframe || x3d tags : auto generate 3d worlds with aframe. (see examples folder)
• dQuery - NEW. Recently started. utils for querying domonic. (alt + 0 for the º symbol)
See the docs/code for more features… https://domonic.readthedocs.io/
print(html(body(h1('Hello, World!'))))
<html><body><h1>Hello, World!</h1></body></html>
python3 -m pip install domonic
or if you had it before upgrade:
python3 -m pip install domonic --upgrade
prepend attributes with an underscore ( avoids clashing with python keywords )
test = label(_class='classname', _for="someinput")
print(test)
<label class="classname" for="someinput"></label>
render takes 2 parameters, some domonic and an optional output file.
page = div(span('Hello World'))
render(page, 'index.html')
So you can build your own static site generator using python
python doesn’t allow hyphens in parameter names. so use variable keyword argument syntax for custom data-tags
div("test", **{"_data-test":"test"} )
to create your own elements use the DOM API
from domonic.dom import *
site = html()
el = document.createElement('myelement')
site.appendChild(el)
print(site)
There’s an evolving DOM. Check code/docs to see what’s currently implemented. i.e
mysite.querySelectorAll('button')
There is a javascript package being started that mirrors the js API:
from domonic.javascript import Math
print(Math.random())
from domonic.javascript import Array
myArr=Array(1,2,3)
print(myArr.splice(1))
from domonic.javascript import URL
url = URL('https://somesite.com/blog/article-one#some-hash')
print(url.protocol)
print(url.host)
print(url.pathname)
print(url.hash)
# from domonic.javascript import Global
# Global.decodeURIComponent(...
# Global.encodeComponent(...
# from domonic.javascript import Date
# etc..
You can use setInterval and clearInterval with params
x=0
def hi(inc):
global x
x = x+inc
print(x)
test = window.setInterval(hi, 1000, 2)
import time
time.sleep(5)
window.clearInterval(test)
print(f"Final value of x:{x}")
You can update a-tags the same way as it inherits from URL:
from domonic.html import *
atag = a(_href="https://somesite.com:8000/blog/article-one#some-hash")
print('href:',atag.href)
print('protocol:',atag.protocol)
print('port:',atag.port)
atag.protocol = "http"
atag.port = 8983
print(atag)
Styling is now supported…
mytag = div("hi", _id="test")
mytag.style.backgroundColor = "black"
mytag.style.fontSize = "12px"
print(mytag)
# <div id="test" style="background-color:black;font-size:12px;">hi</div>
several other undocumented features. Take a look at the code.
decorate any function that returns python objects to return json instead
from domonic.JSON import *
@return_json
def somefunc():
myObj = {"hi":[1,2,3]}
return myObj
print( somefunc() )
print( is_json(somefunc()) )
convert json arrays into html tables…
from domonic.JSON import *
# 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…
from domonic.JSON import *
json_data = JSON.parse_file('somefile.json')
JSON.csvify(json_data, 'data.csv')
convert csv files to json…
from domonic.JSON import *
json_data =JSON.csv2json("data.csv")
print(json_data)
more to come…
Well I tested circle and that works… But should be fine :)
All tags extend ‘Node’ and ‘tag’. So will have DOM and magic methods available to them. see the docs.
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)
You can tween values with the tween library:
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()
to use 3d tags can be used if you import the js
from domonic.html import *
from domonic.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 uses the º symbol (alt+0).
d = html(head(body(li(_class='things'), div(_id="test"))))
º(d) # you need to init a dom first. i.e. a html element
# now you can use it
print( º('#test') )
print( º('.things') )
a = º('<div class="test2"></div>')
print( a )
b = º('#test').append(a)
print(b)
Only recently started so check to see what’s implemented.
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.
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…
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.)

while you can create a div with content like :
div("some content")
python doesn’t allow named params before unamed ones. So you can’t do this:
div(_class="container", p("Some content") )
or it will complain the params are in the wrong order. You have to instead put content before attributes:
div( p("Some content"), _class="container")
which is annoying when a div gets long.
You can get around this by using ‘html’ which is available on every Element:
div( _class=“container” ).html(“Some content”)
This is NOT like jQuery html func that returns just the inner content. use innerHTML for that.
It is used specifically for rendering.
If templates are typed incorrectly they will not work. Here are some solutions to common errors when creating large templates… ( i.e. see bootstrap5 examples in test_domonic.py )
IndexError: list index out of range - You most likely didn’t put a underscore on an attribute.
SyntaxError: invalid syntax - You are Missing a comma between attributes
SyntaxError: positional argument follows keyword argument - You have to pass attributes LAST. and strings and objects first. see docs
TypeError: unsupported operand type(s) for ** or pow(): ‘str’ and ‘dict’ - You are Missing a comma between attributes. before the **{}
There’s a few args you can pass to domonic on the command line to help you out.
To launch the docs for a quick reference to the APIs use:
python3 -m domonic -h
This command will attempt to generate a template from a webpage. (only simple pages for now)
python3 -m domonic -d http://eventual.technology
Then you can edit/tweak it to get what you need and build new components quicker.
A browser based file browser. Working example of how components can work: https://github.com/byteface/Blueberry/
A cron viewer: https://github.com/byteface/ezcron/
A basic game: https://github.com/byteface/bombdisposer/

There’s also several useage examples in the repo so pull and have a look.
Feel free to contribute if you find it useful.
Email me, message me directly if you like or create a discussion on here.
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.
. venv/bin/activate
pip install -r requirements-dev.txt
cd examples
python lifecalendar.py
See Makefile:
make test
or to test a single function:
python -m unittest tests.test_javascript.domonicTestCase.test_javascript_array
python -m unittest tests.test_dQuery.domonicTestCase.test_dQuery_addClass
see coverage
coverage run -m unittest discover tests/
coverage report
See Makefile:
cd docs
make html
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.
