I made some Go scripts that require user input fmt.Scanln(&fileName) during the execution. When I use the Go debugger built into VSCode which is the launch type, it works but there is no way to enter any prompts when your exeuctable asks for a input. With other programming languages like NodeJS and PHP, there is way to run the scripts in "debugging mode" where it will run the code but before it executes the code, it will wait to attach to a debugger on your system and then execute the code. This has always allowed me to use the terminal for inputs in the executable.

For example to do this in NodeJS, you will use node --inspect-brk=0.0.0.0 main.js instead of node main.js and then run the debugger in VSCode to attach it to the executing script. Is there a way to do this with Go? Do I need to set something up to achieve this?

I am on Linux Mint and cannot find any commands to run go run . but to wait for a debugger to attach to the executable before executing.

So, I need to monitor a fairly large nested directory tree for changes on Linux. It seems like there are a few different watcher modules that I could use -- fsnotify and notify being the main ones, both of which use the inotify interface and attempt to set watches on each individual subdirectory and maintain all their watchers as things change. I have way too many directories for that to be a workable approach. It looks like the underlying issue is just that this is a difficult problem on Linux; both inotify and fanotify have some issues which make them difficult for library authors to use to present a clean and useful API.

Long story short - I coded up an fanotify-based solution which seems like a good start of what I need, and I'm planning on sharing it back in the hopes that it's useful. I guess my question is, did I miss something? Is there already an easy and straightforward way to monitor a big directory for changes?
