no matching window title found

Error message

no matching window title found

What it means

queryWindowTitles enumerates all top-level windows via EnumWindows and matches window titles against a pattern. When no window title matches, the collected title is empty and this error is raised; the wrapped message includes any enumeration error (e.g. from getWindowFileName) for diagnostics.

Solutions

1. Confirm the expected application window actually exists and its title contains the searched text (inspect with Get-Process | Select MainWindowTitle).
2. Avoid tools/scripts that rewrite the terminal window title ($Host.UI.RawUI.WindowTitle or echo -ne '\e]0;...') if window-title detection matters.
3. This is usually harmless: the caller treats unmatched titles as 'not that app' and falls back to default behavior - no action needed unless you rely on window detection.

// enumerate and fall back to default behavior when nothing matches
title, err := term.QueryWindowTitles(pattern)
if err != nil {
    // no matching window: proceed with non-window-specific behavior
}

When it happens

Trigger: Calling QueryWindowTitles(pattern) when no currently visible top-level window's title contains the requested text, or when every candidate window failed processing (e.g. process open failures) leaving title empty.

Common situations: oh-my-posh checking whether it runs inside a known terminal window and the terminal's window title was customized by the user or a shell integration; running in a session without a visible window (ssh, service); the terminal's title changed due to a newer shell version.
