83 # 1) A command is entered at the prompt and you press return.
84 # The following steps happen:
85 # * iterm2_preexec is invoked
86 # * PS1 is set to ITERM2_PRECMD_PS1
87 # * ITERM2_SHOULD_DECORATE_PROMPT is set to 1
88 # * The command executes (possibly reading or modifying PS1)
89 # * iterm2_precmd is invoked
90 # * ITERM2_PRECMD_PS1 is set to PS1 (as modified by command execution)
91 # * PS1 gets our escape sequences added to it
92 # * zsh displays your prompt
93 # * You start entering a command
95 # 2) You press ^C while entering a command at the prompt.
96 # The following steps happen:
97 # * (iterm2_preexec is NOT invoked)
98 # * iterm2_precmd is invoked
99 # * iterm2_before_cmd_executes is called since we detected that iterm2_preexec was not run
100 # * (ITERM2_PRECMD_PS1 and PS1 are not messed with, since PS1 already has our escape
101 # sequences and ITERM2_PRECMD_PS1 already has PS1's original value)
102 # * zsh displays your prompt
103 # * You start entering a command
105 # 3) A new shell is born.
106 # * PS1 has some initial value, either zsh's default or a value set before this script is sourced.
107 # * iterm2_precmd is invoked
108 # * ITERM2_SHOULD_DECORATE_PROMPT is initialized to 1
109 # * ITERM2_PRECMD_PS1 is set to the initial value of PS1
110 # * PS1 gets our escape sequences added to it
111 # * Your prompt is shown and you may begin entering a command.
114 # * ITERM2_SHOULD_DECORATE_PROMPT is 1 during and just after command execution, and "" while the prompt is
115 # shown and until you enter a command and press return.
116 # * PS1 does not have our escape sequences during command execution
117 # * After the command executes but before a new one begins, PS1 has escape sequences and
118 # ITERM2_PRECMD_PS1 has PS1's original value.
