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.

Rob Pike: Gobs of data (2011)
Someone made a benchmark of serialization libraries in go [1], and I was surprised to see gobs is one of the slowest ones, specially for decoding. I suspect part of the reason is that the API doesn't not allow reusing decoders [2]. From my explorations it seems like both JSON [3], message-pack [4] and CBOR [5] are better alternatives.
By the way, in Go there are a like a million JSON encoders because a lot of things in the std library are not really coded for maximum performance but more for easy of usage, it seems. Perhaps this is the right balance for certain things (ex: the http library, see [6]).
There are also a bunch of libraries that allow you to modify a JSON file "in place", without having to fully deserialize into structs (ex: GJSON/SJSON [7] [8]). This sounds very convenient and more efficient that fully de/serializing if we just need to change the data a little.

Introducing Dot: The Magical Path Manipulator for Go! (open source)
A similar project: https://github.com/tidwall/sjson
- Modification of json string without deserialisation into map/struct
- Need help on appending fields to json bytes
-
Anyone learning Go or building a side project?
Not sure what you need to do but there is https://github.com/tidwall/sjson for quick manipulation.

What are your favorite packages to use?
I love https://github.com/tidwall/gjson and https://github.com/tidwall/sjson for fast and frictionless json reading and editing. It makes life so much easier for cases where you don't want to model a tree of nightmare-ish API responses, like Elasticsearch.

Show HN: Error return traces for Go, inspired by Zig
Can you explain why we should this over https://github.com/pkg/errors?

Cant wait for less verbose error handling
The pkg/errors package offers some nice add-ons for easier error handling. Too bad it was put into maintenance mode pending whatever changes/improvements are coming in Go 2.

isse for go path in neovim
I can't figure out the issue so here for some help, I am using `neovim/nvim-lspconfig` my `gopls` doesn't recognise external paths such as `github.com/pkg/errors` , it throws error`could not import github.com/pkg/errors (cannot find package "github.com/pkg/errors" in any of /usr/local/go/src/github.com/pkg/errors (from $GOROOT) /Users/ra compiler (BrokenImport)\`
-
What am I supposed to be doing with errors?
Also - there are some error handling utils that allow you to wrap errors before passing: https://github.com/pkg/errors
-
Go error handling is not verbose but the error handling itself.
Should've been something like errors.Newf("failed to foofoo %s", foo) instead and preferably never invent %w but have some controlled way to wrap like errors.Wrapf(err, "failed to foofoo %s", foo) that was in ye olde github.com/pkg/errors.
-
How to wrap the error best?
Prefer using errors.Wrap and errors.Wrapf from https://github.com/pkg/errors . It's frozen because they don't want to add features, waiting for a re-write of error handling in Go2.

Getting at the type of error after it has been wrapped with errors.Wrap
Im using zerolog and in order to get the stack trace for my error I have to wrap my error in errors.Wrap from "github.com/pkg/errors".
-
When ia a good time to panic?
And for "real programs" you can use https://github.com/pkg/errors (if you want stack traces)
