This plugin adds a few functions that are useful when using [iTerm2](https://www.iterm2.com/).
To use it, add _iterm2_ to the plugins array of your zshrc file:
```
plugins=(... iterm2)
```
Optionally, the plugin also applies the [Shell Integration Script for iTerm2](https://iterm2.com/documentation-shell-integration.html).
You can enable the integration with zstyle. It's important to add this line
before the line sourcing oh-my-zsh:
```
zstyle :omz:plugins:iterm2 shell-integration yes
```
## Plugin commands
* `_iterm2_command <iterm2-command>`
@ -24,6 +33,9 @@ plugins=(... iterm2)
* `iterm2_tab_color_reset`
resets the color of iTerm2's current tab back to default.
For shell integration features see the [official documentation](https://iterm2.com/documentation-shell-integration.html).

# 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.
