Bash

All languages

These real terminal captures use a historical development build. They are not current release certification; independent output review and current installed-wheel scenario checks remain pending.

Overview

This worked example compares code.sh. Advertised filename extensions: .sh.

What changes

Enable errexit, nounset and pipefail; default missing or empty first argument to World; introduce greet with local name and invoke it; append ! to greeting.

Before

#!/bin/bash
NAME=$1
echo "Hello, $NAME"

After

#!/bin/bash
set -euo pipefail

NAME=${1:-World}

greet() {
    local name=$1
    echo "Hello, ${name}!"
}

greet "$NAME"

Things to know

• Strict-mode behavior and defaulting change semantics; function extraction is only part of the edit.

Recorded output

Recorded from a real native CLI through rs-rich-record. A refactoring label does not prove equivalent behavior. Build identities.

Try it

Save the two source blocks as separate files with the shown extension, then compare them:

intentumdiff file before/code.sh after/code.sh

The installed Python wheel includes its parser components. The native CLI requires a component directory. Compare the result with the source change described above; agreement between APIs alone is not proof of correctness.
