Go generate only runs on startup

[AndreasBackx]

I've got the following file that runs packr via go generate. But it only seems to run go generate when initially running realize start.

//go:generate packr
package main

import (
    "github.com/gobuffalo/packr"
    "path/filepath"
)

func SchemaString() string {
    box := packr.NewBox("./schema")
    schema := ""

    for _, filename := range box.List() {
        extension := filepath.Ext(filename)
        if extension == ".graphql" {
            schema += box.String(filename)
        }
    }
    return schema
}

The following is my .realize.yaml:

settings:
  legacy:
    force: false
    interval: 0s
schema:
- name: project
  path: .
  commands:
    generate:
      status: true
    install:
      status: true
    run:
      status: true
  watcher:
    extensions:
    - go
    - graphql
    paths:
    - /
    ignored_paths:
    - .git
    - .realize
    - vendor

Output:

Initially it starts out without a main-packr.go file which is initially generated by go generate which triggers a second install. But after that it is not regenerated indicating that go generate is only called on startup.

Hi, i'll create a sample with packr as soon as possible in order to test this

[mikegleasonjr]

same with test, only run tests on startup

[AndreasBackx]

@Asoseil you can use this project of mine to test it. It was only a proof-of-concept project.

This seems to be unrelated to packr, it does the same thing for me with a simple script I wrote as well. It detects the change and rebuilds, but only runs go generate on startup.

same happening with test here

The same problem happens with test/vet/fmt as well. Also, this affect 2.0.2 release and master while 2.0.1 is okay.
