\title{Format a log message with \code{glue} and ANSI escape codes to add colors}
\usage{
layout_glue_colors(
level,
msg,
namespace = NA_character_,
.logcall = sys.call(),
.topcall = sys.call(-1),
.topenv = parent.frame()
)
}
\arguments{
\item{level}{log level, see \code{\link[=log_levels]{log_levels()}} for more details}
\item{msg}{string message}
\item{namespace}{string referring to the \code{logger} environment /
config to be used to override the target of the message record to
be used instead of the default namespace, which is defined by the
R package name from which the logger was called, and falls back
to a common, global namespace.}
\item{.logcall}{the logging call being evaluated (useful in
formatters and layouts when you want to have access to the raw,
unevaluated R expression)}
\item{.topcall}{R expression from which the logging function was
called (useful in formatters and layouts to extract the calling
function's name or arguments)}
\item{.topenv}{original frame of the \code{.topcall} calling function
where the formatter function will be evaluated and that is used
to look up the \code{namespace} as well via \code{logger:::top_env_name}}
}
\value{
character vector
}
\description{
Colour log levels based on their severity. Log levels are coloured
with \code{\link[=colorize_by_log_level]{colorize_by_log_level()}} and the messages are coloured with
\code{\link[=grayscale_by_log_level]{grayscale_by_log_level()}}.
}
\note{
This functionality depends on the \pkg{crayon} package.
