NAME

CohortExplorer::Command::History - CohortExplorer class to print command history

SYNOPSIS

history [OPTIONS]

hist [OPTIONS]

DESCRIPTION

This class is inherited from CLI::Framework::Command and overrides the following methods:

usage_text()

This method returns the usage information for the command.

option_spec()

(  
   [ 'show|s'  => 'show command history'  ],
   [ 'clear|c' => 'clear command history' ] 
)

validate( $opts, @args )

This method throws throw_cmd_validation_exception exception imported from CLI::Framework::Exceptions if

• arguments are supplied to this command because this command does not accept any arguments, or

• mutually exclusive options (i.e. show and clear) are specified together

run( $opts, @args )

This method performs option specific processing.

This class imports the variable $COMMAND_HISTORY from CohortExplorer::Command::Query to load user's saved commands. The history command enables the user to keep track of previously saved commands and use the information such as options and arguments to build new commands.
