EpicStuff

A few somewhat useful (Epic) python objects/functions (Stuff)

Installation

pip install epicstuff

Dict

Lets you access a dictionary's keys as attributes

JDict version

Points to a target instead of converting it into a (new) Dict object. Useful for when your "target" is say, a CommentedMap and you don't want to loose the comments.

• Example:

from epicstuff import Dict

d = Dict({})

d.x = 1

BoxDict version

Simpler (less features) than Box (and faster i think) but with more features (recursive conversion and creation on access) than jdict (and without some of the "extra" stuff)

• Example:

from epicstuff import Dict

d = Dict({"a": 1, "b": {"c": 2, "d": 3}}, _convert=None)

print(d.b.c)  # 2

Rich Trace

Easily install terminal-wide rich.traceback and use helpers to ensure pretty tracebacks with async functions.

• Example:

from epicstuff import run_install_trace

• or:

from epicstuff import rich_trace

@rich_trace
async def some_func():
	raise Exception
some_func()

• or:

@rich_trace(_return=0)
async def some_func():
	raise Exception
some_func()

• or:

with rich_trace():
	raise Exception

Bar

Makes using nested progress bars from rich.progress easier

• Example:

basically replaces

from rich.progress import Progress

with Progress() as progress:
	task = progress.add_task("task", total=100)
	for i in range(100):
		sub_task = progress.add_task("subtask", total=100)
		for j in range(100):
			time.sleep(0.01)  # some task

			progress.update(sub_task, advance=1)

		progress.remove_task(sub_task)
		progress.update(task, advance=1)

with

from epicstuff import Bar

with Bar() as bar:
	for i in bar(range(100)):
		for j in bar(range(100), transient=True):
			time.sleep(0.01)  # some task

with minor extra features (fancier default bar)

Timer

a simple timer to time execution of code a code segment

• Example:

from epicstuff import timer

with timer():
	pass  # some code

# outputs: Time elapsed: 0.0 seconds
# message can be changed by passing a string with {} to timer

s

An autoformatting string. Removes extra indent and leading/trailing newlines.

• Example:

from epicstuff import s

string = s('''
	line 1
		line 2
			line 3
''') + 'line 4'

print(s)
# line 1
# 	line 2
# 		line 3
# line 4

Permissify

make function ignore extra arguments instead of raising an error.

• Example:

from epicstuff import perm

def tmp(a, b=2): ...

perm(tmp)(1, 2, b=3, c=5)  # this will run without raising TypeError

Stuff

extra functions:

• open: overwriting open with Path.open and encoding='utf8' (also accepts str)
• wrap: just a renamed functools.partial
• rmap: map but recursive for lists and dicts
  • takes list or dict and 2 functions, will apply function 1 to all keys and function 2 to all values
• Tee: Text stream that writes to multiple underlying streams. (Example: redirect stdout to terminal and a file)
• Pointer: an object you can kinda use like a pointer. (Example number = Pointer(5), number._t = 6)

TODO:

• when doing bar in bar with the second bar being transient, make so that the dots continue from where the previous bar left off
• implement auto transient for bar in bar
• add and implement simple=False for .Bar.track()

Stuff:

• Note to self:
  • "self install" using pip install -U -e .
  • upload by running python -m build then twine upload --skip-existing dist/*
