; electron-builder NSIS customisation (auto-included: build/installer.nsh).
;
; Per-user install, no elevation (package.json build.nsis). This does two things
; beyond the default: put the bundled daemon on the user's PATH so `meshbay-node`
; works in a terminal, and clean up the one piece of state that lives outside
; the install directory (the W3 "run at sign-in" launcher).
;
; Deliberately NOT touched:
; - %LOCALAPPDATA%\meshbay\ (node.toml, keystore.enc, unlock.key, data/) --
; the keystore must survive an uninstall/reinstall; installers place files,
; never remove secrets.
!include "WinMessages.nsh"
!include "WordFunc.nsh"
!insertmacro WordAdd
!insertmacro un.WordAdd
; The dir electron-builder drops resources into. `meshbay-node.exe` and its
; frozen Python live directly in here. A fixed suffix of $INSTDIR, so both the
; add (install) and the remove (uninstall, where $INSTDIR is still known) match
; the exact same string.

!macro customInstall
; resources\node-runtime\meshbay-node.exe is about to be overwritten; a
; daemon still running from a previous version holds the file open.

; Add the daemon dir to the per-user PATH (HKCU\Environment). WordAdd is a
; stock NSIS macro over a ';'-delimited list -- it is a no-op if the entry is
; already there, so a reinstall does not double it. New shells only; the
; broadcast tells already-open Explorer/shells to reload the environment.
