catgl: Print colored messages

In raveio: File-System Toolbox for RAVE Project

Print colored messages

Description

Print colored messages

Usage

catgl(..., .envir = parent.frame(), level = "DEBUG", .pal, .capture = FALSE)

Arguments

..., .envir	passed to glue
level	passed to cat2
.pal	see pal in cat2
.capture	logical, whether to capture message and return it without printing

Details

The level has order that sorted from low to high: "DEBUG", "DEFAULT", "INFO", "WARNING", "ERROR", "FATAL". Each different level will display different colors and icons before the message. You can suppress messages with certain levels by setting 'raveio' options via raveio_setopt('verbose_level', <level>). Messages with levels lower than the threshold will be muffled. See examples.

Value

The message as characters

Examples

# ------------------ Basic Styles ---------------------

# Temporarily change verbose level for example
raveio_setopt('verbose_level', 'DEBUG', FALSE)

# debug
catgl('Debug message', level = 'DEBUG')

# default
catgl('Default message', level = 'DEFAULT')

# info
catgl('Info message', level = 'INFO')

# warning
catgl('Warning message', level = 'WARNING')

# error
catgl('Error message', level = 'ERROR')

try({
  # fatal, will call stop and raise error
  catgl('Error message', level = 'FATAL')
}, silent = TRUE)

# ------------------ Muffle messages ---------------------

# Temporarily change verbose level to 'WARNING'
raveio_setopt('verbose_level', 'WARNING', FALSE)

# default, muffled
catgl('Default message')

# message printed for level >= Warning
catgl('Default message', level = 'WARNING')
catgl('Default message', level = 'ERROR')
