You should use gometalinter to check your code for warnings/suggestions. That will help you write better code and you’ll know where your code is erroring out. I use vim-go to have this integration in my editor itself.
I ran your code against gometalinter and this is what I have. ➜ $?=0 /tmp/temp [10:28AM] % gometalinter --enable-all main.go:22::warning: line is 1388 characters (lll) main.go:22:194:warning: "ridiculus" is a misspelling of "ridiculous" (misspell) main.go:16:7:warning: exported const TestDataCount should have comment or be unexported (golint) main.go:26:9:warning: error return value not checked (f.Write([]byte(data))) (errcheck) main.go:20::warning: Errors unhandled.,LOW,HIGH (gas) main.go:26::warning: Errors unhandled.,LOW,HIGH (gas) main.go:10:6:warning: func random is unused (U1000) (unused) main.go:10:1:warning: random is unused (deadcode) >>> 6s elasped... ➜ $?=1 /tmp/temp [10:28AM] % On Wed, Jun 28, 2017 at 12:56 AM, <ken.kofi.acq...@gmail.com> wrote: > I am running the following program: > > package main > > import ( > "math/rand" > "os" > "gopkg.in/cheggaaa/pb.v1" > ) > func random(min, max int) int { > return rand.Intn(max - min) + min > } > var data = "" > const TestDataCount = 20000 > func main() { > bar := pb.StartNew(TestDataCount) > f,_ := os.Create("HelloWorld.txt") > for i := 0; i < TestDataCount; i++ { > data = data + "Lorem ipsum dolor sit amet, consectetuer adipiscing elit. > Aenean commodo ligula eget dolor.
