black

[Skaperen]

it turns out that i do not like various details of how black formats my code. so, i hope this is just defaults that can be changed, somehow. i suppose that my use can just be limited to looking at the diff output, that might be enough. but there are quite many little details, making diff output be rather large and cumbersome to consider.

There are config that can be used.

Pro-tip: If you're asking yourself "Do I need to configure anything?" the answer is No. Black is all about sensible defaults.

If Black or Blue change a lot in your code then you don't follow PEP-8 coding style.
In my code the the formatter make minor changes(as i mostly follow PEP-8),if i don't like any i go quick in change manually the small changes needed.

Black is a PEP 8 compliant opinionated formatter.
Black reformats entire files in place.
Style configuration options are deliberately limited and rarely added.
It doesn't take previous formatting into account (see Pragmatism for exceptions).

(as i mostly follow PEP-8)

i'm curious what you do different than PEP-8.

one of the things i do is lining up things vertically where they are already on multiple lines.

# like this:
    alpha = 'one'
    beta  = 'two'
    gamma = 3

but black ...

# does this:
    alpha = 'one'
    beta = 'two'
    gamma = 3

it changes most of the quotes from single to double on string literals. this is perhaps my greatest dislike.

it adds spaces after commas in argument lists but not at the ends where the enclosing parenthesis are. my style is to usually have no spaces, but where the spaces help, put them in all position, or verticalize it.

i was told it makes argument lists vertical, but i didn't see that happen.

how did you install this? it is not in the Ubuntu 20.04 repository and i still have not gotten pip to quit using the wrong directory.

the black site works. the blue site sorta seems to, but has operational issues (i can't scroll all the way down, for one).

You most fix this it's just the normal way.

pip install blue

Blue will only use single quotes or convert to it code use double quotes.
Test a messed up code.

# coin.py
import random
import time

class Coin:
    def __init__(self ):
      self.sideup="Heads"

    def toss(self):
            if random.randrange( 2)== 0:
              self.sideup =    "Heads"
            else:
              self.sideup= "Tails"

def toss_result(    ):
  my_coin=Coin( )
  print(f"This side is up: {my_coin.sideup}")
  print("I am tossing the coin...")
  time.sleep(4)
  my_coin.toss()
  print(f"This side is up: {my_coin.sideup}")

if __name__ == "__main__" :
  toss_result( )

After run Blue.

So work fine,think i change to Blue because like single quotes better.

The problem with single quotes is that you can't use contractions and possessive 's between single quotes, for example

sentence = "you can't use contractions and possessive 's"

It is even worse in french where articles and pronouns are contracted before a vowel, for example

phrase = "C'est l'arrivée de la course"

Aesthetically I'd like to switch to single quotes everywhere but I don't think it is a good idea.

It's not a problem Blue will understand when it can not convert to single quotes.

# text_test.py
sentence = "you can't use contractions and possessive 's"
phrase = "C'est l'arrivée de la course"
can_change = "My car is blue"
print(sentence)
print(phrase)
print(can_change)

Run Blue.

After the line that could changed to single quotes is changed.

# text_test.py
sentence = "you can't use contractions and possessive 's"
phrase = "C'est l'arrivée de la course"
can_change = 'My car is blue'
print(sentence)
print(phrase)
print(can_change)

Output:
you can't use contractions and possessive 's
C'est l'arrivée de la course
My car is blue

vous faites de bons points, surtout pour le français.

pip worked this time. maybe it saw that i was logging it. but, now, black doesn't work. installing blue installed a newer version of black. looks like it is patched:
