When releasing a variant made command has anyone run into:


./main.go:4:5: undefined: cmd.YAML

Has anyone tried to marry variant and goreleaser? I love the idea of automatically building the binary and updating homebrew.

davidvasandaniover 6 years ago

are there any examples for how to integrate https://github.com/davidovich/summon with variant?

davidvasandaniover 6 years ago

I’m looking to include additional shell scripts in the variant binary vs trying to write out the each full script within the variant config.

cc @Erik Osterman (Cloud Posse) wondering if you’ve run into this before ☝️🏻

Erik Osterman (Cloud Posse)over 6 years ago

Aha yes @mumoshu has somethings he is working on for this

Erik Osterman (Cloud Posse)over 6 years ago

I think one is called mod

Erik Osterman (Cloud Posse)over 6 years ago

I am away right now but will look it up

https://github.com/variantdev/mod/

davidvasandaniover 6 years ago

I was looking at this and reading the Slack archives but didn’t realize it could be used with shell scripts.

@davidvasandani Hey! I understand your use-case but unfortunately we don't yet have an example

davidvasandaniover 6 years ago

If I could figure out how to get started I’d be happy to contribute one.

mumoshuover 6 years ago

You can add some go code to the go source output by variant build but

davidvasandaniover 6 years ago

I’m using variant in a couple different projects but all my shellscripts are in a single variant yaml file 😳

mumoshuover 6 years ago

Perhaps you'd prefer easier ways, like you add a few lines to your variant command yaml and variant build to get the bundled binary..?

davidvasandaniover 6 years ago

Exactly.

mumoshuover 6 years ago

Great. So I was considering to enhance variant or mod to cover that

bundle:
  files:
  - ./utils.sh
 - ./helpers.sh

tasks:
  foo:
    script: |
      {{.moduleDir}}/utils.sh myutilfunc arg1 arg2

davidvasandaniover 6 years ago

☝️🏻 exactly this.

mumoshuover 6 years ago

Good. I'll try implementing it soon 😃

mumoshuover 6 years ago

In the meantime, you'll be able to integrate summon like this:


package main

import (
	"fmt"
	"os"
)

func main() {
	assetsDir := "assets"

	box := packr.New("Bundled Assets", assetsDir)

	summoner, err := summon.New(r.box)
	if err != nil {
		fmt.Fprintf(os.Stderr, "%v\n", err)
		os.Exit(1)
	}

	msg, err := r.s.Summon(
		summon.All(true),
		summon.Raw(true),
		summon.Dest(assetsDir),
	)
	if err != nil {
		fmt.Fprintf(os.Stderr, "%v\n", err)
		os.Exit(1)
	}

	fmt.Printf("summon: %s\n", msg)

	// Inject go code generated by `variant build` here...
}

mumoshuover 6 years ago

And in your script call it like assets/utils.sh myutilfunc arg1 arg2.
packr2 bundles all the files under assets and summon extracts em into assets

davidvasandaniover 6 years ago

I’ll give this a shot. Thanks @mumoshu 🎉

davidvasandaniover 6 years ago(edited)

I’ve added summon and packr2 but these are the errors I get when I build:


./main.go:16:30: undefined: r
./main.go:22:14: undefined: r

davidvasandaniover 6 years ago

Whats r and s on this line msg, err := r.s.Summon(

mumoshuover 6 years ago

Ah sry that's a copypaste issue. Replace r.s with summoner

davidvasandaniover 6 years ago


./main.go:16:31: undefined: r
./main.go:22:23: cannot call non-function summoner (type *summon.Driver)

davidvasandaniover 6 years ago(edited)

@mumoshu This is my main.go file:

davidvasandaniover 6 years ago


package main

import (
	"fmt"
	"os"
  "<http://github.com/mumoshu/variant/cmd|github.com/mumoshu/variant/cmd>"
  "<http://github.com/gobuffalo/packr/v2|github.com/gobuffalo/packr/v2>"
  "<http://github.com/davidovich/summon/pkg/summon|github.com/davidovich/summon/pkg/summon>"
)

func main() {
  assetsDir := "assets"

  box := packr.New("Bundled Assets", assetsDir)

  summoner, err := summon.New(r.box)
  if err != nil {
      fmt.Fprintf(os.Stderr, "%v\n", err)
      os.Exit(1)
  }

  msg, err := summoner(
      summon.All(true),
      summon.Raw(true),
      summon.Dest(assetsDir),
  )
  if err != nil {
      fmt.Fprintf(os.Stderr, "%v\n", err)
      os.Exit(1)
  }

  fmt.Printf("summon: %s\n", msg)

  cmd.YAML(`
		#!/usr/bin/env variant

tasks:
  hello:
    script: |
      echo Hello $(whoami)!
  whoami:
    script: |
      assets/whoami.sh
	`)
}

mumoshuover 6 years ago

summon.New(r.box) should be summon.New(box)

mumoshuover 6 years ago

and msg, err := summoner( should be msg, err := summoner.Summon(

davidvasandaniover 6 years ago

thanks! testing now.

davidvasandaniover 6 years ago

Do you recommend I inject the output of variant build ... or use cmd.YAML and inject the output of the variant file?

davidvasandaniover 6 years ago

When you responded I was using variant build

davidvasandaniover 6 years ago

this is the latest main.go

davidvasandaniover 6 years ago


./main.go:36:17: *variant.TaskDef literal evaluated but not used
./main.go:36: unknown field 'fun' in struct literal of type variant.TaskDef

davidvasandaniover 6 years ago

I’ll push up my example.

@mumoshu any suggestions to help get me unstuck?
