xorriso: Dialog
8 Dialog, Readline, Result pager
********************************
Dialog mode prompts for a quoted input line, parses it into words, and
performs them as commands with their parameters. It provides assisting
services to make dialog more comfortable.
Readline is an enhancement for the input line. You may already know
it from the bash shell. Whether it is available in 'xorriso' depends on
the availability of package readline-dev at the time when 'xorriso' was
built from its sourcecode.
Readline lets the user move the cursor over the text in the line by help
of the Left and the Right arrow keys. Text may be inserted at the
cursor position. The Delete key removes the character under the cursor.
Up and Down arrow keys navigate through the history of previous input
lines.
See info readline for more info about libreadline.
Command -page activates a built-in result text pager which may be
convenient in dialog mode. After an action has output the given number
of terminal lines, the pager prompts the user for a line of input.
An empty line lets 'xorriso' resume work until the next page is output.
The single character "@" disables paging for the current action.
"@@@", "x", "q", "X", or "Q" request that the current action aborts and
suppress further result output.
Any other line input will be interpreted as new dialog line. The
current action is requested to abort. Afterwards, the input line is
executed.
Some actions apply paging to their info output, too.
The request to abort may or may not be obeyed by the current action.
All actions try to abort as soon as possible.
