unable to get exec path

Error message

unable to get exec path

What it means

When creating the startup shortcut, komorebic resolves its own executable directory via std::env::current_exe() to point the shortcut at komorebic-no-console.exe. It panics with 'unable to get exec path' if the OS cannot determine the running binary's path.

Solutions

  1. Run komorebic.exe from its stable install directory (e.g. scoop/cargo bin), not a temp path
  2. Reinstall komorebi so the binaries are intact and co-located
  3. Exclude the install directory from antivirus
  4. Create the Startup shortcut manually pointing to komorebic-no-console.exe if current_exe keeps failing

Example fix

// before: run from a transient path
C:\Temp\komorebic.exe startup install
// after: run from the real install location
C:\Users\me\scoop\apps\komorebi\current\komorebic.exe startup install
Defensive patterns

Strategy: try-catch

Validate before calling

// Verify the executable resolves and komorebic-no-console.exe is adjacent
fn startup_ready() -> bool {
    std::env::current_exe().ok()
        .map(|mut p| { p.pop(); p.join("komorebic-no-console.exe").is_file() })
        .unwrap_or(false)
}

Try / catch

match std::env::current_exe() {
    Ok(exe) => install_shortcut(exe),
    Err(e) => eprintln!("shortcut install skipped: cannot resolve exec path: {e}"),
}

Prevention

When it happens

Trigger: Running 'komorebic startup install' (or equivalent) when std::env::current_exe() fails: the binary was deleted/replaced mid-run, launched via an unlinked path, or the launch environment cannot report the image path.

Common situations: Installing autostart from a wiped temp dir; antivirus quarantining komorebic.exe during the operation; exotic launchers (e.g. some package shims) that obscure the executable path.
