gma provide feature makes an aggregated main file from main and dependencies files.
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.
go get github.com/takashabe/gma
require go1.11 or later and GO111MODULE environemnts
gma -main main.go -depends util.go,util2.go -depends util/util.go
-main require: the central file of aggregation
-depends optional: dependencies files
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")
}
