hello-bat-fwi9

A tiny Windows hello package. Install it, import it, call hello().

import hello_bat_fwi9

hello_bat_fwi9.hello()

hello() copies the bundled hello.bat to %LOCALAPPDATA%\hello-bat-fwi9\ and runs it. The batch writes hello.txt with hello from the underground and opens it in Notepad.

The .bat is bundled with the package, fixed, and readable. Nothing is downloaded at runtime. pip install itself never runs it; the only trigger is your call.

Install

pip install hello-bat-fwi9

Use

Run the bundled batch

import hello_bat_fwi9
hello_bat_fwi9.hello()

This writes:

%LOCALAPPDATA%\hello-bat-fwi9\hello.txt

with:

hello from the underground

and opens it in Notepad. run_hello() is an alias.

Native popup

import hello_bat_fwi9
hello_bat_fwi9.show_hello()
# or
hello_bat_fwi9.popup()

hello("hi there", "my title") also shows the native message box for backward compatibility.

The popup is:

• title hello / body hello by default
• information icon
• one OK button
• topmost and foregrounded
• modal; blocks until you click OK or close it
• Windows only; on other platforms it returns False

Quiet mode

$env:LN9_QUIET = "1"

hello() and the popup return False and do nothing. Useful for tests and CI.

What the batch does

src/hello_bat_fwi9/hello.bat is the whole file:

@echo off
setlocal
set "TXT=%~dp0hello.txt"
> "%TXT%" echo hello from the underground
start "" notepad "%TXT%"
endlocal

• writes/overwrites hello.txt next to the copied batch
• opens it in Notepad
• no network, no download, no persistence, no elevation
• one fixed file, included in the wheel

hello() copies it to %LOCALAPPDATA%\hello-bat-fwi9\hello.bat before running, so it does not write into site-packages.

Command line

hello-bat-fwi9              # run the bundled batch
hello-bat-fwi9 --popup      # show the native message box
hello-bat-fwi9 "hi there" --popup
hello-bat-fwi9 --info

What it is not

• No install-time execution. pip install only unpacks files.
• No .exe; the package includes one .bat.
• No download at runtime.
• No network access.
• No persistence, startup hook, or scheduled task.
• No hidden execution: hello() is the trigger and the batch is readable.

Uninstall

pip uninstall hello-bat-fwi9

The copy in %LOCALAPPDATA%\hello-bat-fwi9\ is left behind; delete that folder to remove it.
