如何添加自定义pylint警告

Question

我想在所有打印语句的Pyint中添加一条警告消息，提醒自己我有这些语句，以防打印敏感信息。这可能吗？我只能找到关于禁用pylint错误的答案，而不能启用新错误。

Answer 1

您可以将打印添加到pylintrc:中的坏内置中

[DEPRECATED_BUILTINS]
# List of builtins function names that should not be used, separated by a comma
bad-functions=print
load-plugins=
pylint.extensions.bad_builtin,

创建一个像Code Apprentice建议的自定义检查器也应该相对容易，比如

from typing import TYPE_CHECKING
from astroid import nodes
from pylint.checkers import BaseChecker
from pylint.checkers.utils import check_messages
from pylint.interfaces import IAstroidChecker
if TYPE_CHECKING:
from pylint.lint import PyLinter
class PrintUsedChecker(BaseChecker):
name = "no_print_allowed"
msgs = {
"W5001": (
"Used builtin function %s",
"print-used",
"a warning message reminding myself I have them in case I "
"print sensitive information",
)
}
@check_messages("print-used")
def visit_call(self, node: nodes.Call) -> None:
if isinstance(node.func, nodes.Name):
if node.func.name == "print":
self.add_message("print-used", node=node)

def register(linter: "PyLinter") -> None:
linter.register_checker(PrintUsedChecker(linter))

然后将其添加到pylintrc:中的加载插件中

load-plugins=
your.code.namespace.print_used,

我建议编写一个自定义检查器。我以前从未这样做过，但如何做到这一点的文档在这里：https://pylint.pycqa.org/en/latest/how_tos/custom_checkers.html
