YAML Configuration


  • input:

    Patterns to include in execution and reports.

    Note: Inspecode runs errcheck for each Go package and the input patterns are used for selecting Go packages containing input files. Therefore, the files excluded by the patterns are processed if they are contained in Go packages that also contain input files, and you may even see logs related to the excluded files in the job console. However, Inspecode eventually ignores any issues detected on the excluded files when generating job reports.

  • ignore:

    Patterns to exclude from execution and reports.

    Note: Just like input:, the ignore patterns may not be applied completely when running errcheck.

  • auto-fix:


  • config-file:


  • machine:

    • cpu:

      Amount of CPU. The default machine has 0.75 CPU with 2880 MiB RAM.

  • options:

    Below is the list of options that are supported:

            if true, check for ignored type assertion results
            if true, check for errors assigned to blank identifier
    -exclude string
            Path to a file containing a list of functions to exclude from checking
    -ignore value
            [deprecated] comma-separated list of pairs of the form pkg:regex
              the regex is used to ignore names within pkg. (default "fmt:.*")
    -ignorepkg string
            comma-separated list of package paths to ignore
            if true, checking of _test.go files is disabled
    -tags value
            space-separated list of build tags to include

YAML Examples

  • With default options:

      errcheck: default
  • With custom machine:

          cpu: 1.5 # 1.5 CPU, 5760 MiB RAM
  • With custom options:

        options: [-asserts, -blank]

Resolving Dependencies

errcheck requires all the dependencies to build, so Inspecode resolves the dependencies in the same manner as go test. See the go test page for the details.
