packr2 not parsing flags correctly

[andypwarren]

Hi. I have my application entry point (main.go) in a subdirectory e.g. cmd/main.go and the repo is using go modules. When I run packr2 build -v cmd/main.go it complies the binary fine but it cant find the boxes I setup in the main.go DEBU[2019-01-15T09:49:14Z] found 0 boxes

I have tried cd'ing into the cmd directory and running packr2 but it complains it can't find the go.mod file as I have set GO111MODULE=on

Can you provide a working example and the output of of the commands with -v?

Packr2 follows import paths to find boxes, if you’re not importing a package it won’t find you boxes. If you want the old style, folder walking, then use the skip imports flag.

Thanks for the hint about imports. I have got this working now but for others stumbling across this.
I have the following directory structure (a common structure for Cobra CLI projects, although simplified for the purpose of this example)

- cmd/
-- main.go
- templates/
-- hello.txt
- go.mod
- go.sum

Here's the basic main.go file to demonstrate the issue

package main

import (
	"fmt"
	"log"

	"github.com/gobuffalo/packr/v2"
)

func main() {
	box := packr.New("templates", "../templates")
	s, err := box.FindString("hello.txt")
	if err != nil {
		log.Fatalf("error finding string: %v", err)
	}
	fmt.Println(s)
}

I set go module support:
export GO111MODULE=on
in the module root directory I run packr2 with ignore imports
packr2 --ignore-imports -v
Then build it normally with go
go build cmd/main.go
then clean up the generated files
packr2 clean

Although I couldn't get ignore imports to work with the packr2 build command
packr2 --ignore-imports build -v cmd/main.go
I get the following error
flag provided but not defined: -ignore-imports

I have the same. Flag --ignore-imports is not recognize.

I found
packr2 --ignore-imports build cmd/main.go would always fail with the error
flag provided but not defined: -ignore-imports

Breaking up the command worked though.

packr2 --ignore-imports build
go build  cmd/main.go

If someone would like to open a PR to fix this, it would be very welcome, otherwise It’ll be a bit before I can get to this. I’m backed up at work.
