Golang -- Getting started

Build

Follow this guild to build golang from source.

cd src && ./all.bash

# If you do not want to run tests, then
./make.bash

Also, remember to clear cache go clean --cache after rebuilding go, or use -a argument when running go build.

Go tools

• go fmt ./... formats go code.
• golangci-lint is the most used linter for Golang.
• deadcode detector

Debug

go mod edit -replace is the way to go to use a customized branch or commit of a dependence.

delve

dlv attach pid is a useful command to see the internals of a running process. Under the hood, delve calls Unix system call ptrace. Inside Alpine

apk add --update --no-cache go
go install github.com/go-delve/delve/cmd/dlv@latest
export PATH=$PATH:/root/go/bin

Not sure why using alpine, delve cannot find the debug symbols.
