# Marveen - Windows telepítő (WSL alapú)
# Futtatás: PowerShell-ben: .\install-windows.ps1

# NOTE: wsl.exe emits its output as UTF-16LE, so PowerShell captures each char
# followed by a \0 byte ("U\0b\0u\0n\0t\0u\0"). `-match "Ubuntu"` then fails ->
# the script thinks Ubuntu is missing, re-runs `wsl --install -d Ubuntu` and
# exits EVERY time, never reaching [3/5] (2026-06-04 re-entry bug, kártya
# 3BB2E738). Fix: strip the stray \0 from wsl output before matching (see the
# `-replace "`0", ""` at each wsl-capture site below). We intentionally do NOT
# touch [Console]::OutputEncoding globally -- that can garble the banner glyphs
# on Windows PowerShell 5.1; the targeted null-strip is side-effect-free.

# Step 3: hand over to install-linux.sh INSIDE WSL, with interactive stdin.
#
# This is the ONLY install path now, whether Ubuntu was just installed or was
# already there. The old steps 3-5 passed multi-line PowerShell here-strings to
# `wsl bash -c`, and that transport is broken in three independent ways
# (measured on Windows PowerShell 5.1 + WSL2): every line keeps a trailing CR
# from the CRLF script file (bash: "set: invalid option" on line 1), PowerShell
# strips the embedded double quotes when building the native command line
# (syntax errors), and PowerShell expands the `$VAR`s meant for bash with its
# own values (empty INSTALL_DIR, a Windows-side PATH). bash then exited 2, the
# exit code was never checked, and the script printed "Függőségek telepítve".
# Worse, a quote on the WEB_PORT line made Windows PowerShell 5.1 refuse to
# PARSE the file at all ("The token '&&' is not a valid statement separator"),
# so on 5.1 the installer stopped before running a single step. install-linux.sh
# does everything those steps did (and much more: auth check, systemd units,
# channel pairing), so the duplicate is removed instead of patched.
