## Golden config for golangci-lint v1.46.2
#
# This is the best config for golangci-lint based on my experience and opinion.
# It is very strict, but not extremely strict.
# Feel free to adopt and change it for your needs.

run:
  # Timeout for analysis, e.g. 30s, 5m.
  # Default: 1m
  timeout: 30m

  # Define the Go version limit.
  # Mainly related to generics support in go1.18.
  # Default: use Go version from the go.mod file, fallback on the env var `GOVERSION`, fallback on 1.17
  go: "1.17" # TODO: change to 1.18 when most linters support it, see https://github.com/golangci/golangci-lint/issues/2649
