@echo off

rem backtalk -- updating has moved. This script does nothing now.

rem SPDX-License-Identifier: AGPL-3.0-or-later

rem

rem WHY THIS IS EMPTY, because the reason is worth knowing before anyone

rem puts it back.

rem

rem To update safely this script used to copy ITSELF into a folder under

rem LOCALAPPDATA and hand control to the copy. That was real protection

rem against a real bug: cmd reads a .bat by byte offset, so a script that

rem pulls a new version of itself mid-run gets garbled from that point on.

rem

rem It is also, precisely, what malicious software does -- write a copy of

rem yourself somewhere out of sight and run it. Antivirus scores the

rem behaviour and cannot see the intention, and Windows users were being

rem warned about this file. The protection was never worth that price

rem either: it only mattered on an update that changed this very script,

rem and by then the pull had already succeeded. The cost was a warning on

rem every machine; the benefit was a tidier error message on a rare day.

rem

rem The file is kept rather than deleted so an existing Desktop shortcut

rem still finds something here and prints the message below, instead of

rem failing with an error nobody can read.

rem

rem Nothing on macOS or Linux changed. update.sh wraps its work in a shell

rem function and calls it at the very end, so bash reads the whole script

rem into memory before running any of it. It never needed a copy of itself.

rem

rem If this folder has no .git yet because it arrived as a zip, an agent

rem can wire it up once, keeping backtalk.json:

rem git init -b main

rem git remote add origin https://github.com/jaredrhod/backtalk

rem git fetch origin

rem git reset --hard origin/main

echo.

echo Updating has moved, and there is nothing here to run.

echo.

echo Open a chat with your agent and say:

echo.

echo update backtalk and tell me what changed

echo.

echo It does the same job, and it tells you what arrived.

echo.
