Is an indeterminate progress indicator active (currently running)?

Wraps the given forms in an indeterminate progress indicator. If the first form is the keyword :opts, the second form must be a map, containing any/all of these keys:

• :frames - the frames (a sequence of Strings) to use for the indeterminate progress indicator (default is (:ascii-spinner styles))
• :delay-in-ms - the delay (in ms) between frames (default is 100ms)
• :fg-colour - the foregound colour of the indeterminate progress indicator (default is :default) - see the jansi-clj docs for allowed values, and prefix with bright- to get the bright equivalent
• :bg-colour - the background colour of the indeterminate progress indicator (default is :default) - see the jansi-clj docs for allowed values, and prefix with bright- to get the bright equivalent
• :attributes - the attributes of the indeterminate progress indicator (default is [:default]) - see the jansi-clj docs for allowed values

Starts the indeterminate progress indicator, calls fn f (a function of zero parameters), then stops the progress indicator. Returns the result of f.

Note: the animate! macro is preferred over this function.

The optional opts map may have an/all of these keys:

• :frames - the frames (a sequence of Strings) to use for the indeterminate progress indicator (default is (:ascii-spinner styles))
• :delay-in-ms - the delay (in ms) between frames (default is 100ms)
• :fg-colour - the foregound colour of the indeterminate progress indicator (default is :default) - see the jansi-clj docs for allowed values, and prefix with bright- to get the bright equivalent
• :bg-colour - the background colour of the indeterminate progress indicator (default is :default) - see the jansi-clj docs for allowed values, and prefix with bright- to get the bright equivalent
• :attributes - the attributes of the indeterminate progress indicator (default is [:default]) - see the jansi-clj docs for allowed values

The default delay between frames (in milliseconds), if one isn’t specified.

The default indeterminate progress indicator style used, if one isn’t specified, as a keyword that has an associated entry in styles. This style is known to function on all platforms.

Schedules the given values for printing (via clojure.core/print), since clojure.core/print and related output fns interfere with an active indeterminate progress indicator.

Notes:

• output is emitted in between ‘frames’ of the progress indicator, so may not appear immediately
• values are space delimited (as in clojure.core/print) - use clojure.core/str, clojure.core/format, etc. for finer control
• no newlines are inserted - if message(s) are to appear on new lines the caller needs to include \n in the value(s)

What state is the indeterminate progress indicator currently in? One of:

• :inactive
• :active
• :shutting-down

A selection of predefined styles of determinate progress indicators, represented as a map. Only ASCII progress indicators are known to work reliably - other styles depend on the operating system, terminal font & encoding, phase of the moon, and how long since your dog last pooped.
