Duologue is high-level interaction library for Common Lisp. Command line interaction is implemented at the moment. It features coloured printing via cl-ansi-text and readline completion.
(&optional (msg "Yes or no: ") &key (default nil default-p) if-wrong-answer
(color *prompt-color*) (error-color *prompt-error-color*))
Ask for yes or no.
(msg options &key if-wrong-option default (print-options t) (separator "~%")
complete completer (color *prompt-color*) (error-color *prompt-error-color*))
Asks the user to choose one of the given options.
Example:
(choose "Choose: " (list "foo" "bar" "baz") :default "baz")
Tags: menu, choose
(msg options &key if-wrong-option default (print-options t) (separator "~%")
complete completer (test #'eql) (color *prompt-color*)
(error-color *prompt-error-color*))
Asks the user to choose many of the given options.
Example:
(choose-many "Choose: " (list "foo" "bar" "baz") :default "baz")
Tags: menu, choose
(options)
Makes a default completer from a list of options
(&optional msg &key (default nil default-p) (required-p t) validator if-invalid
parser completer (color *prompt-color*) (error-color *prompt-error-color*))
Prompt for a string.
(&optional msg &key default (required-p t) if-invalid (color *prompt-color*)
(error-color *prompt-error-color*))
Prompts for a timestamp.
Returns: the parsed local-time
The input is parsed with chronicity library and transformed to a local-time. The input is validated and the process does not stop until the user enters a valid timestamp address.
(&optional msg &key default (required-p t) if-invalid (color *prompt-color*)
(error-color *prompt-error-color*))
Prompts for an email.
Returns: the entered email
The email is validated and the process does not stop until the user enters a valid email address.
(&optional msg &key default (required-p t) if-invalid (color *prompt-color*)
(error-color *prompt-error-color*))
Prompts for an integer.
Returns: the entered number
(&optional msg &key default (required-p t) if-invalid (color *prompt-color*)
(error-color *prompt-error-color*) probe if-exists (if-does-not-exist :error)
absolute-p file-type directory-p (complete t))
Prompts for a pathname.
(&optional msg &key default (required-p t) if-invalid (color *prompt-color*)
(error-color *prompt-error-color*) probe if-exists (if-does-not-exist :error))
Prompts for an url.
Returns: the entered url
(datum &rest args)
Prints a message on the screen.
A newline is printed iff either newline parameter is T or datum doesn't end with a space. That is, if datum ends in a space, then no newline is printed.
Example:
(say "Hello ~A" "John" :color :blue)
Categories: printing Tags: printing
(msg (&rest options) &body body)
Asks to repeat a task several times and collects its result.
Returns: A list of collected task results
Example: ```lisp (while "Add item?: " (:default t) (prompt "Item: "))
