ATTRIBUTES

All the attributes of Perinci::CmdLine::Base, plus:

log => BOOL (default: 1)

Whether to load Log::Any::App (enable logging output) by default. See "LOGGING" for more details.

use_utf8 => BOOL

From Term::App::Role::Attrs (please see its docs for more details). There are several other attributes added by the role.

undo => BOOL (optional, default 0)

Whether to enable undo/redo functionality. Some things to note if you intend to use undo:

  • These common command-line options will be recognized

    --undo, --redo, --history, --clear-history.

  • Transactions will be used

    use_tx=>1 will be passed to Perinci::Access, which will cause it to initialize the transaction manager. Riap requests begin_tx and commit_tx will enclose the call request to function.

  • Called function will need to support transaction and undo

    Function which does not meet qualifications will refuse to be called.

    Exception is when subcommand is specified with undo=>0, where transaction will not be used for that subcommand. For an example of disabling transaction for some subcommands, see bin/u-trash in the distribution.

undo_dir => STR (optional, default ~/.<program_name>/.undo)

Where to put undo data. This is actually the transaction manager's data dir.
