Errors when running on Go 1.23 projects

[runar-rkmedia]

I tried running this standalone today, after seeing no errors reported in golangci on a repository where they should be reported.

 sloglint -attr-only true -no-global all ./...
-: This application uses version go1.22 of the source-processing packages but runs version go1.23 of 'go list'. It may fail to process source files that rely on newer language features. If so, rebuild the application using a newer version of Go.
./document_client.go:1:1: package requires newer Go version go1.23
...
sloglint: 8 errors during loading

 sloglint -V
sloglint version 0.7.2 linux/amd64
go version go1.23.3 linux/amd64

Not really sure what that message really indicates. Is it just my setup?

hello, can you provide your go.mod file

I confirm, just reproduced it with the latest sloglint running on a Go 1.23 project. This is completely unexpected for me. I'll bump the Go version to 1.23, which will most likely fix the problem. Thanks for the report!

sloglint version 0.7.2 linux/amd64

As the version displayed inside this message is 0.7.2, I guess the linter has been installed using the prebuild binaries.

$ ./sloglint -V

The prebuilt binary of v0.7.2 was built using go1.22.4, so the error is expected with go1.23.

The problem is not the minimum Go version but the Go version used to build the binary.

Technically, no changes are required, you only need to recompile the binary.
