#
# This file is not a configuration example,
# it contains the exhaustive configuration with explanations of the options.

# Options for analysis running.
run:
  # Number of operating system threads (`GOMAXPROCS`) that can execute golangci-lint simultaneously.
  # If it is explicitly set to 0 (i.e. not the default) then golangci-lint will automatically set the value to match Linux container CPU quota.
  # Default: the number of logical CPUs in the machine
  # concurrency: 4

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

  # Exit code when at least one issue was found.
  # Default: 1
  # issues-exit-code: 1

  # Include test files or not.
  # Default: true
  # tests: true

  # List of build tags, all linters use it.
  # Default: []
  # build-tags:
  #  - mytag

  # If set, we pass it to "go list -mod={option}". From "go help modules":
  # If invoked with -mod=readonly, the go command is disallowed from the implicit
  # automatic updating of go.mod described above. Instead, it fails when any changes
  # to go.mod are needed. This setting is most useful to check that go.mod does
  # not need updates, such as in a continuous integration and testing system.
  # If invoked with -mod=vendor, the go command assumes that the vendor
  # directory holds the correct copies of dependencies and ignores
  # the dependency descriptions in go.mod.
  #
  # Allowed values: readonly|vendor|mod
  # Default: ""
  modules-download-mode: readonly

  # Allow multiple parallel golangci-lint instances running.
  # If false, golangci-lint acquires file lock on start.
  # Default: false
  # allow-parallel-runners: true

  # Allow multiple golangci-lint instances running, but serialize them around a lock.
  # If false, golangci-lint exits with an error if it fails to acquire file lock on start.
  # Default: false
  # allow-serial-runners: true

  # Define the Go version limit.
  # Mainly related to generics support since go1.18.
  # Default: use Go version from the go.mod file, fallback on the env var `GOVERSION`, fallback on 1.17
  # go: '1.19'

# output configuration options
output:
  # The formats used to render issues.
  # Format: `colored-line-number`, `line-number`, `json`, `colored-tab`, `tab`, `checkstyle`, `code-climate`, `junit-xml`, `github-actions`, `teamcity`
  # Output path can be either `stdout`, `stderr` or path to the file to write to.
  #
  # For the CLI flag (`--out-format`), multiple formats can be specified by separating them by comma.
  # The output can be specified for each of them by separating format name and path by colon symbol.
  # Example: "--out-format=checkstyle:report.xml,json:stdout,colored-line-number"
  # The CLI flag (`--out-format`) override the configuration file.
