gma (go-main-aggregator)

gma provide feature makes an aggregated main file from main and dependencies files.

Usecase

A most powerful use case is competitive programming. Generally, competitive programming should submit to a single file. You can isolate the main(solver) and common utility files via using gma.

Installation

go get github.com/takashabe/gma

require go1.11 or later and GO111MODULE environemnts

Usage

gma -main main.go -depends util.go,util2.go -depends util/util.go

Options

-main    require: the central file of aggregation
-depends optional: dependencies files

Example

files to use:

• main.go

package main

import (
  "fmt"

  "github.com/takashabe/gma/example/util"
)

func main() {
  fmt.Println(util.Name)
  fmt.Println(util.Foo())
  Foo()
}

• util.go

package main

func Foo() {}

• util/util.go

package util

import "fmt"

const Name = "util.go"

func Foo() string {
  return fmt.Sprintf("util")
}

---

execute gma:

$ gma -main example/main.go -depends example/util.go -depends example/util/util.go
package main

import (
  "fmt"
)

func main() {
  fmt.Println(_util_Foo())
  Foo()
}
func Foo() {
}
func _util_Foo() string {
  return fmt.Sprintf("util")
}
