Supported Generators

Overview

gogenfilter detects files generated by 18 code generation tools through a two-phase approach: filename patterns first (zero I/O), then content markers.

Detection Methods

Tool	Filename Detection	Content Detection
sqlc	models.go, querier.go, query.sql.go, batch.go, *.sql.go	"Code generated by sqlc"
templ	_templ.go suffix	Code generated by templ
go-enum	_enum.go suffix	"Code generated by go-enum"
protobuf	.pb.go, _grpc.pb.go suffix	Code generated by protoc-gen-go
oapi-codegen	None	oapi-codegen content marker
deepcopy-gen	zz_generated.* prefix + .go suffix	"Code generated by deepcopy-gen"
wire	wire_gen.go suffix	"Code generated by Wire"
moq	_moq.go, _moq_test.go suffix	"Code generated by moq"
mockgen	_mock.go suffix	"Code generated by MockGen"
stringer	None	`“Code generated by "stringer"”
mockery	mock_ prefix	"Code generated by mockery"
ent	None	"Code generated by ent" / "Code generated by entc"
gqlgen	None	"Code generated by github.com/99designs/gqlgen"
easyjson	_easyjson.go suffix	"Code generated by easyjson"
msgp	None	"Code generated by github.com/tinylib/msgp"
counterfeiter	fake_ prefix	"Code generated by counterfeiter"
go-swagger	None	"Code generated by go-swagger"
Generic fallback	None	Any // Code generated by comment

Generic Fallback

The generic detector catches any tool that follows Go’s standard code generation comment convention from go.dev/s/generatedcode. This means even tools not explicitly supported will be detected if they include the standard comment.

Adding New Generators

The detector table is the single source of truth. Each entry has:

• An option (FilterOption)
• A reason (FilterReason)
• An optional matchFilename function (Phase 1)
• An optional checkContent function (Phase 2)

Derived lists like AllFilterOptions() and AllFilterReasons() are auto-generated from this table.
