cannot vendor pg_query_go

[TotallyGamerJet]

This library cannot be vendored because parser/include doesn't contain any go files.

Error:

# github.com/pganalyze/pg_query_go/v6/parser
vendor/github.com/pganalyze/pg_query_go/v6/parser/parser.go:7:10: fatal error: 'pg_query.h' file not found
    7 | #include "pg_query.h"
      |          ^~~~~~~~~~~~

Reproduce:

package main

import _ "github.com/pganalyze/pg_query_go/v6"

func main() {}

go get github.com/pganalyze/pg_query_go/v6@latest
go mod vendor
go build

@TotallyGamerJet Thanks for opening this issue! This is indeed a problem - I know that you can work around it using additional tools like modvendor.

I'm curious, are you sure its just the missing .go files that are the problem, vs the fact that the files in question are not Go files at all? (if its the former, we may be able to do something, but my assumption has always been that Go's vendor tooling doesn't handle C language files)

[TotallyGamerJet]

Yes I am sure that it's the missing go files because the other C files in the parser package are present. It's just the ones in the sub directories which are only C and header files. We also came across this in Purego which was fixed by adding empty files.
