Detection

Combined Detection

DetectReason(filePath, content string, opts ...FilterOption) FilterReason

Checks if a file is auto-generated based on filename and content. No I/O — you provide the content. Returns the reason or ReasonNotFiltered.

reason := gogenfilter.DetectReason("db/models.go", content,
    gogenfilter.FilterSQLC,
    gogenfilter.FilterGeneric,
)

DetectReasonReader(filePath string, r io.Reader, opts ...FilterOption) (FilterReason, error)

Same as DetectReason but reads from an io.Reader.

r := bytes.NewBufferString(content)
reason, err := gogenfilter.DetectReasonReader("file.go", r, opts...)

Per-Generator Detection

Each generator has dedicated Is*Generated(filePath, content string) bool functions:

Function	Checks
IsSQLCGenerated	Filename + content markers
IsTemplGenerated	_templ.go suffix + templ.Component
IsGoEnumGenerated	_enum.go suffix + content
IsProtobufGenerated	.pb.go / _grpc.pb.go + content
IsOapiGenerated	oapi-codegen content marker
IsDeepcopyGenerated	zz_generated.* + content
IsWireGenerated	wire_gen.go + content
IsMoqGenerated	_moq.go + content
IsMockgenGenerated	_mock.go / mock_ + content
IsStringerGenerated	Content marker
IsGenericGenerated	Any Code generated by comment

Filename Matchers

Zero-I/O filename checks:

gogenfilter.MatchesSQLCFilename("db/query.sql.go") // true

Content Checkers

gogenfilter.HasSQLCContent(content)
gogenfilter.HasSQLCCodePatterns(content)
