What is Wrong with GNU Coreutils?

I recently came across Open Sourcing: Base 64 Converter on steemit. Talk about a low quality post. Some people are just really reaching for content on steemit anymore.

Why Do I not Like This?

Well, it's a nothingburger. There is no point. Base64 is part of so many languages and tools. I do not see the need for this. Normally, I would not care, but this is one of those, "If you find this tool useful, look inward" situations. I want to use this opportunity to really help people rather than let this one go.

What is wrong with gnu?

cat file | base64 > file.b64

or

cat file.b64 | base64 -d > file

What is wrong with Python

cat file.b64 | python -c "import base64, sys; print(base64.b64decode(sys.stdin.read().strip()).decode('utf-8'))"

cat file | python -c "import base64, sys; print(base64.b64encode(sys.stdin.read().strip().encode('utf-8')).decode('utf-8'))"

What is wrong with NodeJS

cat file | node -e "process.stdin.on('data', d => console.log(Buffer.from(d).toString('base64')))"

cat file.b64 | node -e "process.stdin.on('data', d => console.log(Buffer.from(d.toString().trim(), 'base64').toString()))"

What is wrong with Golang

cat file | go run <(cat <<EOF
package main
import (
    "encoding/base64"
    "fmt"
    "io/ioutil"
    "os"
)
func main() {
    data, _ := ioutil.ReadAll(os.Stdin)
    fmt.Println(base64.StdEncoding.EncodeToString(data))
}
EOF
)

cat file.b64 | go run <(cat <<EOF
package main

import (
    "encoding/base64"
    "fmt"
    "io/ioutil"
    "os"
)

func main() {
    data, _ := ioutil.ReadAll(os.Stdin)
    decoded, _ := base64.StdEncoding.DecodeString(string(data))
    fmt.Println(string(decoded))
}
EOF
