# golangci-lint configuration for dtvem
# Documentation: https://golangci-lint.run/docs/configuration/file/

# Config version (must be a string for v2.x)
version: "2"

run:
  # Timeout for analysis
  timeout: 5m
  # Include test files in linting
  tests: true

# Output configuration (v2.x format)
output:
  formats:
    text:
      path: stdout
      colors: true
  # Sort results by file, linter, severity
  sort-order:
    - file
    - linter
  # Show statistics
  show-stats: true

# Linters configuration (v2.x format)
linters:
  # Start with no linters enabled
  default: none

  # Enable specific linters
  enable:
    # Bugs & Correctness (ERRORS - will fail build)
    - errcheck        # Check for unchecked errors
    - govet           # Reports suspicious constructs
    - ineffassign     # Detect ineffectual assignments
    - unused          # Check for unused constants, variables, functions and types

    # Style & Formatting (ERRORS - will fail build)
    - misspell        # Finds commonly misspelled English words in comments
    - whitespace      # Detect leading/trailing whitespace

    # Code Quality (ERRORS - will fail build)
    - dupl            # Detect code duplication
    - goconst         # Find repeated strings that could be constants
    - gocyclo         # Compute cyclomatic complexity

    # Best Practices (ERRORS - will fail build)
    - errorlint       # Find code that will cause problems with error wrapping
    - nilerr          # Find code that returns nil even if it checks that the error is not nil
    - nilnil          # Checks that there is no simultaneous return of nil error and invalid value

  # Linter-specific settings (moved from top-level linters-settings)
  settings:
    # Settings for errcheck
    errcheck:
      # Report about not checking of errors in type assertions
      check-type-assertions: true
      # Report about assignment of errors to blank identifier
      check-blank: false
      # List of functions to exclude from checking
      exclude-functions:
        - (*os.File).Close
        - (*database/sql.Rows).Close

    # Settings for govet
    govet:
      # Enable all analyzers
      enable-all: true
      # Disable specific analyzers
      disable:
        - shadow          # Reports variables that shadow other variables (can be too noisy)
        - fieldalignment  # Reports struct field ordering for memory optimization (too noisy)

    # Settings for gocyclo (cyclomatic complexity)
    gocyclo:
      # Minimal code complexity to report (25 allows for existing complex functions)
      min-complexity: 25

    # Settings for dupl (code duplication)
    dupl:
      # Threshold for duplicate code detection
      threshold: 100

    # Settings for goconst
    goconst:
      # Minimal length of string constant
      min-len: 3
      # Minimum occurrences count to trigger issue
      min-occurrences: 3

    # Settings for misspell
    misspell:
      # Correct spellings using locale preferences
      locale: US

  # Exclusion rules (moved from issues section in v1.x)
  exclusions:
    # Generated files should be ignored
    generated: lax
    # Paths to exclude
    paths:
      - vendor
      - dist
      - .claude
      - ".*\\.pb\\.go$"
    # Rules to exclude specific linters in specific paths
