marvmiloTools

Version: 1.11.3

Dependencies:

• pandas
• dash
• dash-bootstrap-components
• paho-mqtt

Description:

A tool a wrote for myself to have multiple functions and classes avalibale on diffrent servers and devices.

HowTo:

1. Main

1.1 ScriptPrint:

Logging and Output Tool for different Scipts.

Example 1(Printing):

import marvmiloTools as mmt

output = mmt.Output("SCRIPT")
print = output.print

print("hello world")

Output:

2022-04-18 23:53:48.015564 - INFO - [SCRIPT]: hello world

Example 2(Logging):

import marvmiloTools as mmt

output = mmt.Output("SCRIPT", logfile = "output.log")
#cleanup from last time
output.cleanup_logfile()
output.log("logging output")

print = output.print
print("logging prints")

def main():
    1 / 0

output.log_python_error(main)

output.log:

2022-04-18 23:49:41.898101 - INFO - [SCRIPT]: logging output
2022-04-18 23:49:41.898891 - INFO - [SCRIPT]: logging prints
2022-04-18 23:49:41.901410 - ERROR - [SCRIPT]: 
Traceback (most recent call last):
  File "C:\Users\marvi\OneDrive\Projects\PyPImarvmiloTools\marvmiloTools\__init__.py", line 168, in log_python_error
    function()
  File "C:\Users\marvi\OneDrive\Projects\PyPImarvmiloTools\log.py", line 12, in main
    1 / 0
ZeroDivisionError: division by zero

 

1.2 Timer:

A build in timer for measuring runtimes.

Example:

import marvmiloTools as mmt
from time import sleep

#start the timer
mmt.timer.start()

sleep(3)

#pause timer
runtime = mmt.timer.pause()
print("Type of runtime: " + str(type(runtime)))
print("Runtime at pause: " + str(runtime))

#reset timer and get runtime function
mmt.timer.reset()
runtime = mmt.timer.get_runtime()
print("Runtime at reset: " + str(runtime))

#set some laps
mmt.timer.start()
for i in range(3):
    sleep(1)
    runtime = mmt.timer.set_lap()
    print("Runtime at lap " + str(i) + ": " + str(runtime))

#get all laps
laps = mmt.timer.get_laps()
print("Laps: " + str(laps))

sleep(2)

#get time of current lap without setting a lap
lap_runtime = mmt.timer.get_lap_runtime()
print("Current Lap Runtime: " + str(lap_runtime))

Output:

Type of runtime: <class 'datetime.timedelta'>
Runtime at pause: 0:00:03.003270
Runtime at reset: 0:00:00
Runtime at lap 0: 0:00:01.001151
Runtime at lap 1: 0:00:01.001191
Runtime at lap 2: 0:00:01.001231
Laps: [datetime.timedelta(seconds=1, microseconds=1151), datetime.timedelta(seconds=1, microseconds=1191), datetime.timedelta(seconds=1, microseconds=1231)]
Current Lap Runtime: 0:00:02.002030

Create a new instance of timer:

timer = mmt.Timer()
timer.start()
...

 

1.3 get_variable_name

Converting variable in namespace into an string.

Example:

import marvmiloTools as mmt

#declare a variable
variable = "hello world"

#get name as string from variable
variable_name = mmt.get_variable_name(variable, locals())
print(variable_name, type(variable_name))

Output:

variable <class 'str'>

 

1.4 random_ID

Creating a random ID of specific length.

Example:

import marvmiloTools as mmt
print(mmt.random_ID(20))

Output:

R1DBXY64KH73BPPF7WFT

 

1.5 CloudMQTT

CloudMQTT client with multiple functions.

Example:

import marvmiloTools as mmt

#init cloudMQTT client
cloudmqtt = mmt.CloudMQTT(
    client_name = "clientname", 
    channel = "channel", 
    qos = 0
)

#connect to server
cloudmqtt.connect(
    user = "user", 
    pw = "password", 
    addr = "cloudmqtt.com", 
    port = 1234
)

#reconnecting to server if no connection
if not cloudmqtt.check_connection():
    cloudmqtt.reconnect()

#on message function
def on_message(msg, topic):
    print(f"received message: '{msg}', topic: '{topic}'")
    
#binding on_message function to a topic
cloudmqtt.bind(topic = "hello", function = on_message)

#publishing a message
cloudmqtt.publish(topic = "hello", message = "world")

#response function
def on_request(msg, topic):
    resp = "hello world"
    print(f"publishing response: {resp}")
    return(resp)

#binding on_request to request topic
cloudmqtt.bind_response("demo", on_request)

#request data from server
resp = (
    cloudmqtt.request(
        topic = "demo",
        message = ".",
        retry = 5
    )
)
print("got response: " + resp)

#disconnecting form server
cloudmqtt.disconnect()

Output:

received message: 'world', topic: 'hello'
publishing response: hello world
got response: hello world

print(mmt.threads[thread_id].is_alive())

try:
    while True:
        time.sleep(1)
except KeyboardInterrupt:
    for id in mmt.threads:
        mmt.threads[id].stop()

Output:

2. Dash

2.1 flex_style

Dictionary for centering content in dash plotlys html.Div

Example:

import marvmiloTools as mmt
from dash import html

html.Div(
    children = [
        "hello world"
    ],
    style = mmt.dash.flex_style({
        "background-color": "black"
    })
)

 

2.2 mobile_optimization

import dash

app = dash.Dash(__name__, meta_tags = [mmt.dash.mobile_optimization])

 

2.3 content_div

For creating a dynamic scalealbe content Div.

Example:

import marvmiloTools as mmt
from dash import html
import dash_bootstrap_components as dbc

app.layout = html.Div(
    children = [
        dbc.Navbar(...),
        mmt.dash.content_div(
            width = "1000px",
            padding = "5%",
            content = [
                "children"
            ]
        )
    ]
)

 

2.4 modal_header_close

Creating an modal header with close button and specific color.

Example:

import marvmiloTools as mmt
import dash_bootstrap_components as dbc

dbc.Modal(
    children = [
        mmt.dash.modal_header_close(
            title = "This is the header",
            close_id = "modal-close", #id of the close button,
            color = "#4287f5" #background color of header
        ),
        dbc.Modal_Body("This is modal body")
    ]
)

 

2.5 random_ID

Creating random IDs compatible with dash.

Example:

import marvmiloTools as mmt
from dash import html

html.Div(
    children = "Hello World",
    id = mmt.dash.random_ID(20)
)

Output ID: 'MNPhNBfXcpVeHVVxuJeF'  

 

2.6 browsertime

Creating a Object in dash html form, wich provides the current clock time of the browser. That means the callbacks can calulate timezone of input.

Add this to your callbacks:

app.clientside_callback(*mmt.dash.browsertime.clientside_callback_args)

Add this in your html layout of the page:

mmt.dash.browsertime.htmlObj()

Example Callback with browser time:

from dash.dependencies import Input, Output, State

@app.callback(
    [Output(...)],
    [Input(...)],
    [State("browser-time", "data")]
)
def callback(... , browsertime):
    datetime_object = mmt.dash.browsertime.datetime(browsertime)
    time_shift = mmt.dash.browsertime.time_shift(browsertime)

Also datetime objects from browsertime string can be created. Time shift can also be calculated.  

2.7 nav

Simply creating a dash navbar with custom items.

import marvmiloTools as mmt

mmt.dash.nav.bar(
    logo = "url(/assets/logo.png)",
    logo_style = {
        "width": "3rem", 
        "height": "3rem",
        "background-size": "cover",
    },
    title = "Navbar Title",
    title_style = {
        "width": "15rem",
        "font-size": "1.5rem"
    }, 
    expand = "lg",
    items = [
        mmt.dash.nav.item.href(
            "Link",
            href = "https://github.com/marvmilo",
            target = "_blank",
            size = "lg"
        ),
        mmt.dash.nav.item.normal(
            "Button",
            id = "button-id",
            size = "lg"
        )
    ]
)

@app.callback(*mmt.dash.nav.callback_args)
def cn(n, is_open):
    return mmt.dash.nav.callback_function(n, is_open)

 

3. Json

3.1 load

For opening and loading a json file to dictionary or marvmiloTools.DictObj

Example:

.
├── example.json
└── script.py
 
example.json:

{
    "hello": "world"
}

script.py:

import marvmiloTools as mmt

dictionary = mmt.json.load("example.json", object=False)
DictObj = mmt.json.load("example.json")

print("Dictionary:")
print(dictionary)
print(type(dictionary))
print()
print("DictObject:")
print(DictObj)
print(type(DictObj))

Execute like this:

~$ python script.py

Output:

Dictionary:
{'hello': 'world'}
<class 'dict'>

DictObject:
{'hello': 'world'}
<class 'marvmiloTools.dictionary_tools.DictObject'>

 

3.2 save

For saving a dictionary or marvmiloTools.DictObject to a json file.

Example:

import marvmiloTools as mmt

dictionary = {"hello": "world"}
DictObj = mmt.dictionary.toObj(dictionary)

#save to json
mmt.json.save(dictionary, filename = "dictionary.json")
mmt.json.save(DictObj, filename = "DictObj.json")

Output as dictionary.json and DictObj.json:

{
    "hello": "world"
}

 

3.3 write

For writing a value directly to a json file without opening and saving.

Example:

.
├── example.json
└── script.py
 
example.json:

{
    "dictionary": {
        "hello": "world"
    },
    "list": [
        "a",
        "b",
        "c"
    ]
}

script.py:

import marvmiloTools as mmt

mmt.json.write("value", "example.json", ["dictionary", "new"])
mmt.json.write("new", "example.json", ["list", 1])

Output example.json:

{
    "dictionary": {
        "hello": "world",
        "new": "value"
    },
    "list": [
        "a",
        "new",
        "b",
        "c"
    ]
}

 

4. Dictionary

4.1 toObj

Transforming to a dictionary to a marvmiloTools.DictObject. This Object can be used like a Class in Python

Example:

# pylint: disable = no-member
import marvmiloTools as mmt

dictionary = {"hello": "world", "list": ["string", 10, {"a": "b"}]}
#convert dictionary to Object
DictObj = mmt.dictionary.toObj(dictionary)

print(type(DictObj))
print(DictObj)
print(DictObj.hello)
print(DictObj.list[2].a)

(usining "# pylint: disable = no-member" with Visual Studio Code for disabeling "DictObj has no hello member" Error)
 
Output:

<class 'marvmiloTools.dictionary_tools.DictObject'>
{'hello': 'world', 'list': ['string', 10, {'a': 'b'}]}
world
b

A DictObject has the same attributes and functions as a dictionary aswell One extra function is pretty:

import marvmiloTools as mmt

DictObj = mmt.dictionary.toObj({"hello": "world"})
print(DictObj.pretty())

Output:

{
    "hello": "world"
}

 

4.2 toDict

Transforming a marvmiloTools.DictObject back to a standart dictionary.

Example:

import marvmiloTools as mmt

DictObj = mmt.dictionary.toObj({"hello": "world"})

#convert to dictionary
dictionary = mmt.dictionary.toDict(DictObj)
print(dictionary)
print(type(dictionary))

Output:

{'hello': 'world'}
<class 'dict'>
