# # For a description of the syntax of this configuration file, # see the file kconfig-language.txt in the NuttX tools repository. # menuconfig SYSTEM_EMBEDLOG bool "embedlog library" default n ---help--- Highly configurable logger for embedded devices. Documentation and more info available on: https://embedlog.kurwinet.pl (don't worry, it's in english). Note: none of the options define how embedlog will behave, it will simply configure whether given feature can be enabled in runtime or no. So enabling CONFIG_EMBEDLOG_ENABLE_TIMESTAMP won't make logger to add timestamp to every message - you will have to also enable timestamp in runtime object. But when CONFIG_EMBEDLOG_ENABLE_TIMESTAMP is disabled, setting timestamp print in runtime will make no difference and timestamp still will not be printed. Library is licensed under BSD 2-clause license. See LICENSE file in the downloaded code for license details if SYSTEM_EMBEDLOG config EMBEDLOG_ENABLE_OUT_FILE bool "Enable logging to file" default n ---help--- If enabled, you will be able to store logs in a file (like on sdcard). Log rotation is available as well. LIbrary automatically handles cases when files are deleted or mountpoint disappears and appear again (like sd card switch). Disabling this will result in smaller code. if EMBEDLOG_ENABLE_OUT_FILE config EMBEDLOG_ENABLE_BINARY_LOGS bool "Enable binary logs" default n ---help--- When enabled, you will be able to print binary data into file to save space (on block device). Note: you will not be able to read such logs with tools like 'less' or 'grep'. You will need to create own reader or use 'hexdump'. endif config EMBEDLOG_ENABLE_OUT_STDERR bool "Enable logging to standard error" default y ---help--- If enabled, you will be able to log messages to standard error (stderr) and/or standard output (stdout). config EMBEDLOG_ENABLE_OUT_TTY bool "Enable printing to tty device" default y ---help--- If enabled, you will be able to configure logger to print directly to tty serial device (like /dev/ttyS1). This might be useful if you want to have nsh in one tty and logs on the other. This is suitable if only one task will be printing logs to one tty, if you want multiple tasks to print into one tty, it's better to enable syslog printing and the syslog handle it. config EMBEDLOG_ENABLE_OUT_CUSTOM bool "Enable custom logging function" default n ---help--- When enabled, you will be able to define own function that accepts fully constructed log message as 'const char *' config EMBEDLOG_ENABLE_TIMESTAMP bool "Enable timestamp in messages" default y ---help--- If enabled, you will be able to configure logger to add timestamp to every loged message. if EMBEDLOG_ENABLE_TIMESTAMP config EMBEDLOG_ENABLE_FRACTIONS bool "Enable fractions of seconds" default y ---help--- If enabled, you will be able to configure logger to add fractions of seconds to timestamp endif config EMBEDLOG_ENABLE_PREFIX bool "Enable prefix" default n ---help--- If enabled, you will be able to set prefix that will be added to each message logged by embedlog. Usefull when multiple tasks print to one tty (via syslog) and you need an easy way to know which program printed given log message. if EMBEDLOG_ENABLE_PREFIX config EMBEDLOG_PREFIX_MAX int "Max prefix length" default 16 ---help--- Maximum length of prefix that can be printed. If prefix exceeds this value it will be truncated. endif #EMBEDLOG_ENABLE_PREFIX config EMBEDLOG_ENABLE_FINFO bool "Enable file info" default y ---help--- If enabled, you will be able to turn on information about location of the log. This uses __FILE__ and __LINE__ macros. if EMBEDLOG_ENABLE_FINFO config EMBEDLOG_FLEN_MAX int "max file name in finfo" default 16 ---help--- finfo look like this [filename.c:123] this parameter defines how long "filename.c" can be, if file name exceeds this value it will be truncated. endif # EMBEDLOG_ENABLE_FINFO config EMBEDLOG_ENABLE_COLORS bool "Enable output colors" default n ---help--- If enabled, you will be able to turn on ANSI colors for messages with different log severities. Disabling this will result in smaller code. config EMBEDLOG_LOG_MAX int "Max length of log message" default 128 ---help--- Maximum length of single log message. This defines length of finall message, so message "foo() returned %s" may consume for example 200 bytes since '%s' may be a long string. Metadata like timestamp or file info uses this space too. Output log will be truncated if it exceeds this value. Lowering/increasing will result in apropriate higher/lower stack usage. config EMBEDLOG_MEM_LINE_SIZE int "Number of bytes in line" default 16 ---help--- How many bytes of memory to print in a single line of el_pmemory call. Check https://embedlog.kurwinet.pl/manuals/el_pmemory.3.html for more information about this. endif # SYSTEM_EMBEDLOG
