[go-nuts] Re: Any embedded scripting language for Go

It's also possible to embed a Go interpreter in a Go App - in this way, the scripting language is Go itself. There are several fairly complete Go interpreters around, including at least: https://github.com/cosmos72/gomacro (disclaimer: I am the author) https://github.com/traefik/yaegi

[go-nuts] Re: CSS-like selectors for Go AST?

Yes, it could be extracted to a separate module, but package github.com/cosmos72/gomacro/ast2 already has very few dependencies. In particular, it does *not* depend on the Go interpreter github.com/cosmos72/gomacro/fast The integer arguments are simple: `y.Get(0)` means "get the first (index =

Re: [go-nuts] Re: Generating code into module cache?

I would personally steer clear of writing anything to the module cache. If you are only code generating into the module cache and not publishing this generated code, by definition that generated content will not be available remotely. Hence any code you publish that depends on this generated

Re: [go-nuts] Golang slow performance inside for loop MySQL Queries

Hello, I created the sql to fetch all info in one call instead of multiple calls per each row. One thing I noticed about golang is that when I ping my Remote DB from localhost (running in vscode) I get ping -> 1.573826274s. So I think this is the reason that all my calls to db are delayed.

Re: [go-nuts] Golang slow performance inside for loop MySQL Queries

To reuse connections, and pay the slowness only on the first connection, set Config.DB.SetMaxIdleConns(2) Or something like that. As *sql.DB is a pool, this can keep two connections alive - one for your main query, and one for the per-row extra queries. Bill a következőt írta (2020.
