70 # There are three possible paths in life. |

71 # |

72 # 1) A command is entered at the prompt and you press return. |

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