Arguments

...

Arguments passed on to rlang::inform

message

The message to display, formatted as a bulleted list. The first element is displayed as an alert bullet prefixed with ! by default. Elements named "*", "i", "v", "x", and "!" are formatted as regular, info, success, failure, and error bullets respectively. See Formatting messages with cli for more about bulleted messaging.

If a message is not supplied, it is expected that the message is generated lazily through cnd_header() and cnd_body() methods. In that case, class must be supplied. Only inform() allows empty messages as it is occasionally useful to build user output incrementally.

If a function, it is stored in the header field of the error condition. This acts as a cnd_header() method that is invoked lazily when the error message is displayed.

class

Subclass of the condition.

body,footer

Additional bullets.

use_cli_format

Whether to format message lazily using cli if available. This results in prettier and more accurate formatting of messages. See local_use_cli() to set this condition field by default in your package namespace.

If set to TRUE, message should be a character vector of individual and unformatted lines. Any newline character "\\n" already present in message is reformatted by cli's paragraph formatter. See Formatting messages with cli.

.file

A connection or a string specifying where to print the message. The default depends on the context, see the stdout vs stderr section.

.subclass

This argument was renamed to class in rlang 0.4.2 for consistency with our conventions for class constructors documented in https://adv-r.hadley.nz/s3.html#s3-subclassing.

.frequency

How frequently should the warning or message be displayed? By default ("always") it is displayed at each time. If "regularly", it is displayed once every 8 hours. If "once", it is displayed once per session.

.frequency_id

A unique identifier for the warning or message. This is used when .frequency is supplied to recognise recurring conditions. This argument must be supplied if .frequency is not set to "always".

Value

feedback in console
