Pylint - 使 pylintrc 配置文件极简

Question

我正在使用 Pylint 检查一堆 .py 文件并进行以下测试:

• 缩进错误

• 混合缩进

• 未使用的变量

我还希望我的 pylintrc 文件尽可能简约。这就是我在乞讨中得到的:

[MASTER]

# Use multiple processes to speed up Pylint.
jobs=1

# Pickle collected data for later comparisons.
persistent=yes

# Allow loading of arbitrary C extensions. Extensions are imported into the
# active Python interpreter and may run arbitrary code.
unsafe-load-any-extension=no


[MESSAGES CONTROL]

# Disable all to choose the Tests one by one
disable=all

# Tests
enable=bad-indentation,       # Used when an unexpected number of indentation’s tabulations or spaces has been found.
       mixed-indentation,     # Used when there are some mixed tabs and spaces in a module.
       unused-variable        # Used when a variable is defined but not used. (Use _var to ignore var).

[REPORTS]

# Set the output format. Available formats are text, parseable, colorized, json
# and msvs (visual studio).You can also give a reporter class, eg
# mypackage.mymodule.MyReporterClass.

我可以把它简化成这样吗:

       unnecessary-semicolon, # Used when a statement is ended by a semi-colon (”;”), which isn’t necessary.
       unused-variable        # Used when a variable is defined but not used. (Use _var to ignore var).


[REPORTS]

# Tells whether to display a full report or only the messages
reports=no

# Activate the evaluation score.
score=no


[FORMAT]

# Regexp for a line that is allowed to be longer than the limit.
ignore-long-lines=^\s*(# )?<?https?://\S+>?$

[EXCEPTIONS]

我相信，如果我只进行那些测试，那么其他许多行都是完全无用的。如果我删除其中一行会怎样？它是否获得默认值？

例如，如果我设置reports=no，我就不需要output-format=text这一行，对吧？如果我删除 jobs=1 行，它仍然是默认行吗？

Answer 1

是的，如果您没有在 pylint 配置中定义任何值，它将使用其默认的已知值。
