Any way to get total nolint flag number?

[caibirdme]

I want to track how many //nolint in codespace, is there any way to do that? Or a new plugin is required

There is nothing inside golangci-lint to do that.
You can use grep instead.

Related to #3132

Thx, I've tried that, but it's not very accurate, because there're a lot of places where nolint shouldn't count, like:

-- README.md
## code conduct
if add `nolint` directive, you must ....

--- xx.go
// nolint: xx    // nolint is acceptable here, because blabla
func foo() error {
}

grep is hard finish this job

[alexandear]

grep -r '//nolint' --include='*.go' --exclude-dir=testdata . | wc -l

FYI, the right form of a nolint directive is //nolint:xx.
No space between // and nolint: and no space between nolint: and xx.
This is important to follow this syntax because this is the difference between a comment and a directive.

About the grep command:

grep -r --include='*.go' '//nolint:' . | wc -l

[ldez]

Not really.
This number is the number of issues before the nolint processor; they are not all related to nolint.

In all cases, this is not the number of nolint directives.

Quick Proof

package main

func main() {
	//nolint:errcheck
	foo()

	foo()

	//nolint:gocyclo
	foo()
}

func foo() error {
	return nil
}

func bar() error {
	return nil
}

$ golangci-lint run -v >/dev/null 2>&1 | grep "nolint_filter:"

Thanks for the explanation.
