The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

betteralign - structs field alignment static analyzer for Go
Retaining comments has been done with using DST (Decorated Syntax Tree) with decorating regular AST. Sadly when using DST we cannot use "fix" mode with SuggestedFixes, but we have to print whole DST to retain decorations. Leading/ending comment positioning isn't well retained in some cases and it's still a work in progress.

Rewriting Go source code with AST tooling
Go AST was never really designed for re-writing of the source. Comments are stored by their byte offset instead of attached to nodes, so re-arranging nodes breaks the output...
Check out my dst (decorated syntax tree) library: it allows you to manipulate Go source without breaking the comments and line-feeds:

betteralign - structs field alignment static analyzer for Go
I've written betteralign, a tool to detect structs that would use less memory if their fields were sorted and optionally sort such fields. Truth be told, there are a few projects already doing this task perfectly such as fieldalignment, maligned and structslop so you might wonder why should you bother with checking this tool at all. This is a fork of an official Go fieldalignment tool and vast majority of the alignment code has remained the same. There are however some notable changes:
-
Saving a Third of Our Memory by Re-Ordering Go Struct Fields
The standard way to check for these was https://github.com/mdempsky/maligned. It is now deprecated in favour of https://pkg.go.dev/golang.org/x/tools/go/analysis/passes/fie....
You can now check for these using go vet:
go install golang.org/x/tools/go/analysis/passes/fieldalignment/cmd/fieldalignment@latest
- Saving a Third of Our Memory by Re-ordering Go Struct Fields
What are some alternatives?
When comparing dst and maligned you can also consider the following projects:
goimports - [mirror] Go Tools
golangci-lint - Fast linters Runner for Go
go - The Go programming language
structslop - structslop is a static analyzer for Go that recommends struct field rearrangements to provide for maximum space/allocation efficiency.
betteralign - Make your Go programs use less memory (maybe)
