# ZSH has a quirk where `preexec` is only run if a command is actually run (i.e
|
|
# pressing ENTER at an empty command line will not cause preexec to fire). This
|
|
# can cause timing issues, as a user who presses "ENTER" without running a command
|
|
# will see the time to the start of the last command, which may be very large.
|
|
|
|
# To fix this, we create STARSHIP_START_TIME upon preexec() firing, and destroy it
|
|
# after drawing the prompt. This ensures that the timing for one command is only
|
|
# ever drawn once (for the prompt immediately after it is run).
