Centralized logging function for Shiny module events. Provides consistent
logging format across all modules with configurable log levels.
Usage
logModuleEvent(module, message, level = "INFO", ...)
Arguments
- module
character. Name of the module generating the log message.
- message
character. The log message to record.
- level
character. Log level: "DEBUG", "INFO", "WARN", or "ERROR".
Defaults to "INFO".
- ...
Additional arguments passed to the log message (for sprintf-style
formatting).
Value
Invisible NULL. Called for side effect of logging.
Details
"WARN" and "ERROR" entries are always emitted with
message(). "INFO" entries are written to standard output
with cat() only when options(nprcgenekeepr.verbose = TRUE)
is set. "DEBUG" entries are written the same way only when
options(nprcgenekeepr.debug = TRUE) is set. Otherwise those two
levels produce no output. An unrecognized level is treated as
"INFO".
Examples
logModuleEvent("modInput", "File uploaded successfully")
logModuleEvent("modPedigree", "Processing %d animals", level = "DEBUG", 100)
logModuleEvent("modGeneticValue", "Calculation failed", level = "ERROR")
#> [2026-10-20 04:48:40] [ERROR] [modGeneticValue] Calculation failed
