| Title: | Easier Use of 'RcppSpdlog' Functions via Wrapper | 
| Description: | Logging functions in 'RcppSpdlog' provide access to the logging functionality from the 'spdlog' 'C++' library. This package offers shorter convenience wrappers for the 'R' functions which match the 'C++' functions, namely via, say, 'spdl::debug()' at the debug level. The actual formatting is done by the 'fmt::format()' function from the 'fmtlib' library (that is also 'std::format()' in 'C++20' or later). |

Convenience Wrappers for 'RcppSpdlog' Logging From 'spdlog'
Description
Several short wrappers for functions from 'RcppSpdlog' package are provided
as a convenience.  Given the potential for clashing names of common and popular
functions names we do not recommend the import the whole package but rather
do importFrom(RcppSpdlog, set_pattern) (or maybe importFrom(RcppSpdlog,
set_pattern)). After that, functionality can be accessed via a convenient shorter
form such as for example spdl::info() to log at the ‘info’ level.
Format strings suitable for the C++ library ‘fmtlib::fmt’ and its
fmt::format() (which as of C++20 becomes ‘std::fmt’) are supported
so the {} is the placeholder for simple (scalar) arguments (for which the
default R formatter is called before passing on a character representation).
Usage
setup(name = "default", level = "warn")
init(level = "warn")
log(level = "warn")
filesetup(s, name = "default", level = "warn")
drop(s)
set_pattern(s)
set_level(s)
trace(s, ...)
debug(s, ...)
info(s, ...)
warn(s, ...)
error(s, ...)
critical(s, ...)
fmt(s, ...)
cat(...)
stopwatch()
elapsed(w)
Arguments
| name | Character value for the name of the logger instance | 
| level | Character value for the logging level | 
| s | Character value for filename, pattern, level, or logging message | 
| ... | Supplementary arguments for the logging string | 
| w | Stopwatch object | 
Value
Nothing is returned from these functions as they are invoked for their side-effects.
Examples
spdl::setup("exampleDemo", "warn")
# and  spdl::init("warn")  and  spdl::log("warn")  are shortcuts
spdl::info("Not seen as level 'info' below 'warn'")
spdl::warn("This warning message is seen")
spdl::set_level("info")
spdl::info("Now this informational message is seen too")
spdl::info("Calls use fmtlib::fmt {} as we can see {}", "under the hood", 42L)
