# There are three possible paths in life.
|
|
#
|
|
# 1) A command is entered at the prompt and you press return.
|
|
# The following steps happen:
|
|
# * iterm2_preexec is invoked
|
|
# * PS1 is set to ITERM2_PRECMD_PS1
|
|
# * ITERM2_SHOULD_DECORATE_PROMPT is set to 1
|
|
# * The command executes (possibly reading or modifying PS1)
|
|
# * iterm2_precmd is invoked
|
|
# * ITERM2_PRECMD_PS1 is set to PS1 (as modified by command execution)
|
|
# * PS1 gets our escape sequences added to it
|
|
# * zsh displays your prompt
|
|
# * You start entering a command
|
|
#
|
|
# 2) You press ^C while entering a command at the prompt.
|
|
# The following steps happen:
|
|
# * (iterm2_preexec is NOT invoked)
|
|
# * iterm2_precmd is invoked
|
|
# * iterm2_before_cmd_executes is called since we detected that iterm2_preexec was not run
|
|
# * (ITERM2_PRECMD_PS1 and PS1 are not messed with, since PS1 already has our escape
|
|
# sequences and ITERM2_PRECMD_PS1 already has PS1's original value)
|
|
# * zsh displays your prompt
|
|
# * You start entering a command
|
|
#
|
|
# 3) A new shell is born.
|
|
# * PS1 has some initial value, either zsh's default or a value set before this script is sourced.
|
|
# * iterm2_precmd is invoked
|
|
# * ITERM2_SHOULD_DECORATE_PROMPT is initialized to 1
|
|
# * ITERM2_PRECMD_PS1 is set to the initial value of PS1
|
|
# * PS1 gets our escape sequences added to it
|
|
# * Your prompt is shown and you may begin entering a command.
|
|
#
|
|
# Invariants:
|
|
# * ITERM2_SHOULD_DECORATE_PROMPT is 1 during and just after command execution, and "" while the prompt is
|
|
# shown and until you enter a command and press return.
|
|
# * PS1 does not have our escape sequences during command execution
|
|
# * After the command executes but before a new one begins, PS1 has escape sequences and
|
|
# ITERM2_PRECMD_PS1 has PS1's original value.
