Unable to import github.com/dolthub/doltgresql/postgres/*

[fanyang01]

Hi Dolt creators,

Inspired by your blog post, I'm interested in using the postgres package to do some MySQL<->Postgresql transpiling tasks. However, I found that go build failed with:

../../go/pkg/mod/github.com/dolthub/[email protected]/postgres/parser/lex/predicates.go:59:17: undefined: reservedKeywords

After checking the contribution guide, I learned that the parser package relies on some source files generated by doltgresql/postgres/parser/build.sh. However, when importing the package in my project via import "github.com/dolthub/doltgresql/postgres/parser/types", it seems impossible to run the script manually since the go mod cache is a read-only directory:

mkdir: parser/gen: Permission denied
./build.sh: line 12: parser/gen/types_regex.tmp: No such file or directory

Could you consider keeping the generated files in the source tree to make the project more compatible with the standard Go toolchain? This would simplify the build process for users who want to integrate the postgres package into their projects.

I appreciate your time and look forward to your feedback.

Hi @fanyang01,

This is an important point I don't think we had considered. We'll discuss internally and get back to you.
