# Output: test string test string (...)

For more advanced usage options, view the help prompt with:

dgen --help

Presets

dgen comes with several presets in order to make your life easier. Each preset represents the character limit on the associated messaging service:

dgen "👀 " fb
# Output: 👀 👀 👀 👀 👀 👀 👀 👀 👀 (... x5000)

List of current dgen presets:

Name / ID	Value	service
fb	5000	Facebook Messenger
twitter	280	Twitter
rpost	40,000	Reddit (post)
rcomment	10,000	Reddit (comment)
rmsg	10,000	Reddit (message)

Performance

dgen is one of the top-of-the-line string generators out there. dgen v1.0.1 sports the following benchmark:

• Input: "benchmark test text "
• Repetitions: 1,000,000
• Duration: 25.050 seconds
• Milliseconds / operation: 0.025039
• Bytes allocated / operation: 21
• Allocations / operation: 0

Integration

dgen is a thin wrapper around an internal library, throughput, which contains the actual repeating and buffering logic. To create a program with dgen's string dumping capabilities, simply import throughput:

import (
  "github.com/steven-xie/dgen/throughput"
  "os"
)


func main() {
  const (
    repstr  = "test string "
    reps    = 5000
    bufsize = throughput.RecommendedBufSize
  )

  // Dump "test string " 5000 times into os.Stdout.
  throughput.Dump(repstr, reps, bufsize, os.Stdout)
}
