66 # There are three possible paths in life.
68 # 1) A command is entered at the prompt and you press return.
69 # The following steps happen:
70 # * iterm2_preexec is invoked
71 # * PS1 is set to ITERM2_PRECMD_PS1
72 # * ITERM2_SHOULD_DECORATE_PROMPT is set to 1
73 # * The command executes (possibly reading or modifying PS1)
74 # * iterm2_precmd is invoked
75 # * ITERM2_PRECMD_PS1 is set to PS1 (as modified by command execution)
76 # * PS1 gets our escape sequences added to it
77 # * zsh displays your prompt
78 # * You start entering a command
80 # 2) You press ^C while entering a command at the prompt.
81 # The following steps happen:
82 # * (iterm2_preexec is NOT invoked)
83 # * iterm2_precmd is invoked
84 # * iterm2_before_cmd_executes is called since we detected that iterm2_preexec was not run
85 # * (ITERM2_PRECMD_PS1 and PS1 are not messed with, since PS1 already has our escape
86 # sequences and ITERM2_PRECMD_PS1 already has PS1's original value)
87 # * zsh displays your prompt
88 # * You start entering a command
90 # 3) A new shell is born.
91 # * PS1 has some initial value, either zsh's default or a value set before this script is sourced.
92 # * iterm2_precmd is invoked
93 # * ITERM2_SHOULD_DECORATE_PROMPT is initialized to 1
94 # * ITERM2_PRECMD_PS1 is set to the initial value of PS1
95 # * PS1 gets our escape sequences added to it
96 # * Your prompt is shown and you may begin entering a command.
99 # * ITERM2_SHOULD_DECORATE_PROMPT is 1 during and just after command execution, and "" while the prompt is
100 # shown and until you enter a command and press return.
101 # * PS1 does not have our escape sequences during command execution
102 # * After the command executes but before a new one begins, PS1 has escape sequences and
103 # ITERM2_PRECMD_PS1 has PS1's original value.
