Here is a list of all the core interception points in CommandBox that you can listen to. Some have interceptData that comes along with them, while others don't. Remember, the interceptData struct is passed by reference. This means modifying any values directly in that struct will affect how processing continues afterwards inside of CommandBox where those values are used.

onCLIStart

Announced when shell first starts, but before any commands are run or output has been flushed to the console.

interceptData

• shellType - The string interactive if starting the interactive shell, or command if running a one-off command and exiting

• args - An array of arguments provided from the OS when box was executed.

• banner - A string containing the CommandBox banner text that displays when in interactive mode.

This fires every time the reload command runs and a fresh shell is created.

onCLIExit

Announced right before the shell exits and control is returned back to the OS. This fires every time the reload command runs right before the shell is destroyed and re-created.

preModuleLoad

Announced before each module that is loaded.

interceptData

• moduleLocation - Path to the module

• moduleName - Name of the module

postModuleLoad

Announced after each module that is loaded.

interceptData

• moduleLocation - Path to the module

• moduleName - Name of the module

• moduleConfig - Struct representing the configuration data for the module.

preModuleUnLoad

Announced before each module that is unloaded.

interceptData

• moduleName - Name of the module

postModuleUnload

Announced after each module that is unloaded.

interceptData

• moduleName - Name of the module

onException

Announced any time an unhandled exception is thrown.

interceptData

• exception - Error struct

preCommand

Announced before the execution of a command. This fires after all command parameters have been evaluated, including expressions. If piping the output of one command into another in a command chain, this will fire twice-- once for each command in the chain.

interceptData

• commandInfo - A struct containing the following keys about the command to execute

  • commandString - A string representing the command name

  • commandReference - The instantiated Command CFC

  • parameters - An array of un-parsed parameter tokens typed in the CLI

  • closestHelpCommand - The CFC path to the most-applicable help command. Used to generate namespace help.

• parameterInfo - A struct containing the following keys about the processed parameters for the command execution

  • positionalParameters - An array of parameter values

  • namedParameters - A struct of name/value pairs. The named parameters are always what is passed to the command's run() method.

  • flags - A struct of flags that were passed in.

postCommand

Announced immediately after command execution is complete. If more than one command is piped together in a command chain, this is announced after each command in the chain.

interceptData

• commandInfo - Same as preCommand above

• parameterInfo - Same as preCommand above

• results - A string that represents any output from the command that hasn't already been flushed to the console.

prePrompt

Announced prior to drawing the prompt in the interactive shell. This interception point can be used to customize the text of the prompt by modifying the prompt variable in intercept data which is an ANSI-formatted string to be output before the cursor.

interceptData

• prompt - An ANSI-formatted string containing the prompt text. Replacing this value will override the prompt.

preProcessLine

Pre and post command fire before and after each command, but that means they fire twice for something like:

echo `package show name`

preProcessLine will fire only once for the above command after the user hits enter but before anything is processed.

interceptData

• line - A string representing the line typed into the shell. Changing the contents of this string will override what actually gets executed.

postProcessLine

Pre and post command fire before and after each command, but that means they fire twice for something like:

echo `package show name`

postProcessLine will fire only once for the above command after the entire line has been executed. Any output is already sent to the console by the time this interception point fires.

interceptData

• line - A string representing the line that was just executed in the shell.
