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.

sqlc: Generating go code from sql statements
For MySQL the situation is a bit different. sqlc uses the parser of TiDB (https://github.com/pingcap/parser), which is a parser that aims to be basically compatible with MySQL, but is quite young and is not a MySQL parser. The most basic queries work, but even simple joins or aggregations usually result in variables with unknown data types or wrong nullability. So you loose a lot of the benefits of sqlc. Manual type annotations for MySQL also do not work most of the time. They are simply ignored and forwarded to MySQL as invalid query if they do not occur on a place where sqlc is expecting them.

Wp-SQLite: WordPress running on an SQLite database
This is a disaster waiting to happen. Regular expressions should never be used to parse non-regular languages, of which SQL is one.
There are a variety of mature MySQL dialect parsers available[1][2], and MySQL should have its own public APIs for transforming a query into an AST. Any of those would be a safer and more correct alternative.

Show HN: Postgres Language Server
Can't you just give some love to the issue https://github.com/pganalyze/libpg_query/issues/44 instead ? As I said before this would be very helpful for the community because there are a lot of libraries that use libpg_query and cannot be used on windows (f.e see https://github.com/lelit/pglast/issues/7).
It seems that the only problem for fixing the problem is:
> Thanks for the offer, but the problem is our team being time limited / having an engineer with a Windows machine ready to take this on, not that we wouldn't want to pay someone to work on it :)
(https://github.com/pganalyze/libpg_query/issues/44#issuecomm...)
Hosting the LSP elsewhere is really needed since if people wanted to go that way they could use Remote ssh (https://code.visualstudio.com/docs/remote/ssh) to host the whole dev environment on linux and connect to it.
Thank you
