zhooks is a tool for displaying the code for all Zsh hook functions (such as precmd), as well as the contents of hook arrays (such as precmd_functions). It is useful in debugging conflicts between interactive scripts.

Simply source zhooks from your .zshrc:

source /path/to/zhooks.plugin.zsh

or load it using your favorite Zsh plugin manager or framework. Then run the command zhooks from the command line to see a thorough report.

zhooks returns true when hooks are being used and false when they are not.

Zsh has the hook functions:

• chpwd
• periodic
• precmd
• preexec
• zshaddhistory
• zsh_directory_name
• zshexit

The corresponding arrays have _functions appended to their names:

• chpwd_functions
• periodic_functions
• precmd_functions
• preexec_functions
• zshaddhistory_functions
• zsh_directory_name_functions
• zshexit_functions
