pycharm - 删除(Python)注释中的参差不齐的行

Question

PyCharm可以包装长于某些数字n(在此示例中为67)的代码行，例如

# this is a really really really really really really really really really really really really really really long comment

变成

# this is a really really really really really really really really
# really really really really really really long comment

**是否有“逆向”功能？*通常，由于在注释中添加和删除了想法，它们最终看起来真的很糟糕，像这样衣衫r:

# this is a the first idea.
# more bla bla, but still relating to first idea. bla bla.
# other bla bla.
# second brilliant idea. oh no, actually it breaks something, so watch out!

我希望Pycharm(可能通过合并插件)能够重新格式化这些注释(填充最大行长)，使其看起来像这样:

# this is a the first idea. more bla bla, but still relating to first 
# idea. bla bla. other bla bla. second brilliant idea. oh no, actually
# it breaks something, so watch out!

如果Pycharm没有此功能，您是否知道可以执行此操作的文本处理器？

Answer 1

默认情况下，这不能在pycharm中完成。没有可用的此类插件。您可以在类似主题中查看答案

Wrapping comments with line breaks in PyCharm

现在您要考虑的以下选项

用sed或awk写点东西，但是这样就不能直接在Windows上工作

为PyCharm编写一个插件。这有很大的学习曲线，需要太多的努力

编写脚本以执行所需的操作

我会选择最后一个选项，因为就工作而言，这是最快的解决方案。您可以选择所需的语言，我选择Python，因为我们知道在格式化供Pycharm使用的Python文件时会出现Python。

因此，脚本的想法是合并连续注释，然后根据列宽包装它们

# this is a test
# this is a best.
# This could be even worst when this is not even good.
# Why should one do it using whatever they have done
import io, re
from textwrap import TextWrapper

import os

current_file = __file__

f = io.open(current_file, 'r')
comment_pattern = re.compile(r"^(\s*)#(.*)")

in_comment = False


def spit_formatted_comments(initial_space, current_comment):
    if current_comment:
        wrapper = TextWrapper(initial_indent=initial_space + "#",
                              subsequent_indent=initial_space + "# ")

        wrapper.width = 80
        data = wrapper.wrap(" ".join(current_comment))
        print(os.linesep.join(data))


for line in f:
    match = comment_pattern.findall(line)

    if match:
        if not in_comment:
            in_comment = True
            current_comment = []
            initial_space = match[0][0]

        current_comment.append(match[0][1])
    elif in_comment:
        in_comment = False
        spit_formatted_comments(initial_space, current_comment)
        current_comment = []
        print(line, end='')
    else:
        print(line, end='')

spit_formatted_comments(initial_space, current_comment)

f.close()
# this is a last line comment to check border

相同的输出是

# this is a test  this is a best.  This could be even worst when this is not
# even good.  Why should one do it using whatever they have done
