README
A simple Go file watcher that will stop & restart your `main()` function on file changes.
## Motivation
I just want to stop my server, and run it again every time I save a file.
## installation
`go install marwan.io/gowatch@latest`
## Usage
from your main app directory, run `gowatch`
## What it does
it reads your current working directory and runs the two typical commands:
- `go build`
- `./`
So this only works in `main` packages.
Also, this ignores your `vendor` folder & your `_test.go` files.
#### FAQ
Q: Why doesn't it just run `go run main.go`?
A: `go run` does the same thing as `go build`, but calls the resulting binary as a subprocess. This makes it harder to reach `stdout` and killing the `main.go` process, won't necessarily kill the subprocess, so you end up trying to run the server twice (which ends up with "port is already taken" kind of error).
Q: How does it compare with other tools?
A: I haven't tried most of them, but I wanted to make this as simple as just running one command to get what I'm looking for without having to turn and twist a lot of knobs.
