v5.0.1

Compare Source

Two v5 API bugs traced to the same root cause: NewAnalyzer captured patterns into the processor before the analysis driver parsed flags, so flag-driven values never reached analysis, and the Config fields had to be typed against internal/pattern to be writable at all.

Fixes

• -enforce-rx, -ignore-rx, -optional-rx, and -allow-empty-rx had no effect under the standalone CLI (#​155). Processor construction now happens lazily on first analyzer run, after flags are populated. golangci-lint integrations were unaffected, since they populate Config programmatically before calling NewAnalyzer.

• analyzer.Config no longer leaks the internal pattern.List type (#​158). The four pattern fields (EnforcePatterns, IgnorePatterns, OptionalPatterns, AllowEmptyPatterns) are now plain []string; pattern compilation has moved inside the analyzer. Library callers populating these fields directly drop the pattern.NewList call:

  // before
  list, _ := pattern.NewList(`.*\.Foo`)
  analyzer.Config{ EnforcePatterns: list }
  
  // after
  analyzer.Config{ EnforcePatterns: []string{`.*\.Foo`} }

Upgrading

go install dev.gaijin.team/go/exhaustruct/v5/cmd/exhaustruct@latest

CLI users reinstall. Library callers update Config field assignments as shown above.

v5.0.0

exhaustruct v5 reshapes how the linter is configured. Struct tags give way to comment directives, opt-in checking lands as a first-class mode, and patterns now reach down to individual fields. The full reference is in the README; this is the highlight reel.

What's new

Comment directives replace struct tags. Three directives — enforce, ignore, optional — now work at three levels of granularity: type definitions, struct literals, and individual fields. A documented priority order keeps the interaction between them predictable.

//exhaustruct:enforce
type Config struct {
    Host    string
    //exhaustruct:optional
    Timeout int
}

Explicit mode (-explicit) flips the default. Instead of checking every struct literal in the project, the linter only checks types you've explicitly marked — either with //exhaustruct:enforce or via -enforce-rx. The right pick for large codebases where exhaustruct should be a precision tool, not a blanket policy.

Field-level regex patterns. The pattern flags now accept Type#Field syntax, so a single configuration line can express optionality across a codebase without touching the type definitions:

.*\.Server#Timeout    # Timeout field in any Server type

Optional patterns (-optional-rx). Regex-based optionality for whole types or specific fields. Closes a long-standing gap for third-party types you can't annotate directly.

Derived types and aliases now follow a clearer rule. Field-level directives carry through type T = U and type T U — so a field marked optional stays optional on every alias and derived type. Type-level directives stay attached to the original type, which means you can promote a derived type to "enforced" independently.

Better diagnostics. -report-full-type-path reports net/http.Cookie instead of http.Cookie, removing ambiguity when import aliases are in play (#​146). -debug-cache-metrics prints per-package cache statistics, useful for tuning patterns on large projects.

Auto-migration. exhaustruct -fix ./... rewrites the legacy exhaustruct:"optional" tags to comment directives in one pass — no manual sweep required.

Breaking changes

• Struct tags retired. exhaustruct:"optional" is no longer recognized. The -fix flag migrates existing tags automatically; the manual equivalent is a one-line move from the field's struct tag to a //exhaustruct:optional comment above (or beside) the field.
• Flag rename. The old include/exclude vocabulary suggested filtering, but the linter has always been about enforcement. The new names say what they do:
  • -include-rx / -i → -enforce-rx
  • -exclude-rx / -e → -ignore-rx
• Module path moves to /v5. Update imports and reinstall:

  go install dev.gaijin.team/go/exhaustruct/v5/cmd/exhaustruct@latest

Fixes

• Implicit pointer composite literals (&T{} returned where the function signature expects *T) are now flagged — previously they slipped past the checker (#​147).
• Aliased struct types resolve through types.Unalias so their fields are inspected even behind an alias chain (#​149).

Migrating from v4

1. Update import paths from /v4 to /v5.
2. Run exhaustruct -fix ./... to rewrite struct tags to comment directives.
3. Replace -include-rx / -i with -enforce-rx, and -exclude-rx / -e with -ignore-rx in CI configs and .golangci.yaml.
4. Optional: consider -explicit if you'd rather opt specific types into checking than opt the rest out.
