delve VS gorequest

At a recent job, we had slightly different containers for local dev; our backend containers (for a Go app) had Air [1] installed for live reloading, plus Delve [2] running inside the container for VS Code's debugger to connect to. We also had a frontend container for local dev, which didn't get deployed as a container, just as static files.

https://github.com/go-delve/delve/releases/tag/v1.21.2 Thanks Derek and the rest of the team for helping us to debug in a normal way!

My employer has a commercial solution for this but Delve does supports `rr` traces natively for this purpose, which gives a complete open-source solution (https://github.com/go-delve/delve/blob/master/Documentation/usage/dlv_replay.md).

delve and related IDE integrations

For time travel debugging in Go:

The Delve debugger for Go supports debugging rr traces: https://github.com/go-delve/delve/blob/master/Documentation/...

Undo (who I work for) maintain a fork that debugs our LiveRecorder recordings: https://docs.undo.io/GoDelve.html

Either rr (https://rr-project.org/) or our UDB debugger (https://undo.io/solutions/products/udb/) can do some time travel debugging of Go programs via GDB's built-in support for Go. I believe its weakness is in support for goroutines, since they don't map well onto its idea of how programs run.

So in my case I use https://github.com/leoluz/nvim-dap-go (which itself calls out to the CLI tool https://github.com/go-delve/delve).

requests is not declarative for me, this is what I mean declarative https://github.com/wenerme/go-wecom/blob/main/wecom/client_agent.go , requests is more like https://github.com/parnurzeal/gorequest , just chain everything. context.Context is not required, but just can be passed by.
