Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How we explored the best practices of GoReleaser X CGO
When implementing SQL Review for PostgreSQL, we introduced pg_query_go as the PostgreSQL parser. The pg_query_go uses the native PostgreSQL parser via C bind, which naturally requires CGO support.

sqlc: Generating go code from sql statements
If you are using Postgres then you are lucky! sqlc uses the official postgres parser (https://github.com/pganalyze/pg_query_go) and while I have never tried it, I guess it works really well.

Semantic Diff for SQL
I wonder if this is a topical thread to check if anyone is aware of a Java based solution to parse a CREATE VIEW statement to get a mapping between the view columns and the corresponding source table columns. I checked out jsqlparser[0] and it does produce an AST which can be parsed using the visitor-pattern[1] but was wondering if there is a more "out-of-the-box" solution. Due to various reasons, querying the database information schema is not an option I can pursue.

Open Source SQL Parsers
JSQLParser can parse multiple SQL dialects like MySQL, Postgres and Oracle. The grammar can be modified to support other SQL dialects.

Racket v8.0
Interesting coincidence - I'm working on a parser that parses the AST produced by JSqlParser[0] for a create view statement to generate mapping between the columns of a view and the columns of its underlying table. It is an interesting example of having to use the visitor pattern[1].
