sub-command 'ds|displayServer': Starts a display server. 
#	Use in a separate console. On Windows use wt (https://github.com/microsoft/terminal) or a linux shell like git-bash to avoid ANSI color issues. 
#	Running "trice ds" inside a console opens a display server to be used for displaying the TRICE logs remotely.
#	Several instances of 'trice l -ds -port ...' (for different ports) will send output there in parallel.
#	Example: 'trice ds': Start display server.
  -color string
    	The format strings can start with a lower or upper case channel information.
    	See https://github.com/rokath/trice/blob/master/pkg/src/triceCheck.c for examples. Color options:

    			  CHAR prints the received bytes as characters.
    			  DUMP prints the received bytes as hex code (see switch -dc too).
    	 (default "TREX")
  -exec string
    	Use to pass an additional command line for port TCP4 (like gdbserver start).
  -hs string
    	PC timestamp for logs and logfile name, options: 'off|none|UTCmicro|zero'
    	This timestamp switch generates the timestamps on the PC only (reception time), what is good enough for many cases.
    	"LOCmicro" means local time with microseconds. "UTCmicro" shows timestamps in universal time. When set to "off" no PC timestamps displayed. (default "LOCmicro")
  -i string
    	Short for '-idlist'.
    	 (default "til.json")
  -idlist string
    	The trice ID list file.
    	The specified JSON file is needed to display the ID coded trices during runtime and should be under version control.

  -liPath string
    	How to store location information paths inside li.json: base, relative, path/relative or full. When relative is given, the location information is stored relative to the current location. If a path is given additionally, like ../../relative the path is added to the location information.
    	 (default "base")
  -locationInformation string
    	The trice location information file.
    	The specified JSON file is needed to display the location information for each ID during runtime.
    	It is regenerated on each add, clean, or insert trice run. When trice log finds a location information file, it is used for
    	log output with location information. Otherwise no location information is displayed, what usually is wanted in the field.
    	This way the newest til.json can be used also with legacy firmware, but the li.json must match the current firmware version.
    	With "off" or "none" suppress the display or generation of the location information. See -tLocFmt for formatting.
    	 (default "li.json")
  -logLevel string
    	Level based log filtering. "off" suppresses everything. If equal to a channel specifier, all with a bigger index inside emitter.Tags logs are not not shown.
    	A typical use case is "-logLevel wrn". Attention this switch influences also location information (-liFmt), target stamps (-ts0, -ts16, -ts32), prefix and suffix information. Set these channel information appropriate.
    	Logs without channel specifier are not suppressed. Using an invalid value like "x" suppresses all logs with a channel specifier. See also CLI switches -ulabel, -pick and -ban. (default "all")
  -logfile string
    	Append all output to logfile. Options are: 'off|none|filename|auto':
    	"off": no logfile (same as "none")

    	"filename": Any other string than "auto", "none" or "off" is treated as a filename. If the file exists, logs are appended.
    	All trice output of the appropriate subcommands is appended per default into the logfile additionally to the normal output.
    	Change the filename with "-logfile myName.txt" or switch logging off with "-logfile none".
    	 (default "off")
  -newlineIndent int
    	Force newline offset for trice format strings with line breaks before end. -1=auto sense (default -1)
  -noCycleCheck
    	Disables reporting of cycle errors.
  -p string
    	short for -port (default "J-LINK")
  -packageFraming string
    	Use "none" (may need CLI switch -d16) or "COBS" as alternative. "COBS" needs "#define TRICE_FRAMING TRICE_FRAMING_COBS" inside "triceConfig.h". (default "TCOBSv1")
  -parity string
    	Serial port bit parity value, options: odd, even (default "none")
  -password string
    	The decrypt passphrase. If you change this value you need to compile the target with the appropriate key (see -showKeys).
    	Encryption is recommended if you deliver firmware to customers and want protect the trice log output. This does work right now only with flex and flexL format.
  -pf string
    	Short for '-packageFraming'. (default "TCOBSv1")
  -pick value
    	Channel(s) to display. This is a multi-flag switch. It can be used several times with a colon separated list of channel descriptors only to display.
    	Example: "-pick err:wrn -pick default" results in suppressing all messages despite of as error, warning and default tagged messages. Not usable in conjunction with "-ban". See also "-logLevel".
  -port string
    	Case insensitive receiver device name: 'serial name|JLINK|STLINK|FILE|FILEBUFFER|TCP4|TCP4BUFFER|DEC|BUFFER|HEX|DUMP.
    	The serial name is like 'COM12' for Windows or a Linux name like '/dev/tty/usb12'.
    	Using a virtual serial COM port on the PC over a FTDI USB adapter is a most likely variant.
    	 (default "J-LINK")
  -prefix string
    	Line prefix, options: any string or 'off|none' or 'source:' followed by 0-12 spaces, 'source:' will be replaced by source value e.g., 'COM17:'. (default "source: ")
  -pw string
    	Short for -password.
  -s	Short for '-showInputBytes'.
  -showID string
    	Format string for displaying first trice ID at start of each line. Example: "debug:%7d ". Default is "". If several trices form a log line only the first trice ID ist displayed.
  -showInputBytes
    	Show incoming bytes, what can be helpful during setup.
    	This is a bool switch. It has no parameters. Its default value is false. If the switch is applied its value is true. You can also set it explicit: =false or =true.
  -showKey
    	Show encryption key. Use this switch for creating your own password keys. If applied together with "-password MySecret" it shows the encryption key.
    	Simply copy this key than into the line "#define ENCRYPT XTEA_KEY( ea, bb, ec, 6f, 31, 80, 4e, b9, 68, e2, fa, ea, ae, f1, 50, 54 ); //!< -password MySecret" inside triceConfig.h.
    	This is a bool switch. It has no parameters. Its default value is false. If the switch is applied its value is true. You can also set it explicit: =false or =true.
  -singleFraming
    	singleFraming demands, that each received package contains not more than a singe Trice message. This is the case for all direct modes or if you "#define TRICE_DEFERRED_TRANSFER_MODE TRICE_SINGLE_PACK_MODE" in your triceConfig.h file. Applying this switch makes sense with COBS and TCOBS framing to improve Trice tool error recognition in received binary data. Not usable together with encryption because of the padding bytes.

    	Print complete statistics on exit.
  -stopbits string
    	Serial port stopbit, options: 1.5, 2 (default "1")
  -suffix string

Choose between "µs" (or "us") and "ms", use "" or 'off' or 'none' to suppress existing target timestamps. Sets ts0, ts16, ts32 if these not passed. If several trices form a log line only the timestamp of first trice ist displayed. (default "µs")
  -ts0 string
    	Target stamp format string at start of each line, if no target stamps existent (configured). Use "" to suppress existing target timestamps. If several trices form a log line only the timestamp of first trice ist displayed. (default "time:            ")
  -ts16 string
    	16-bit Target stamp format string at start of each line, if 16-bit target stamps existent (configured). Choose between "µs" (or "us") and "ms", use "" to suppress or use s.th. like "...%d...". If several trices form a log line only the timestamp of first trice ist displayed. (default "ms")
  -ts32 string
    	32-bit Target stamp format string at start of each line, if 32-bit target stamps existent (configured). Choose between "µs" (or "us"), "ms", "epoch060102150405" like, use "" to suppress or use s.th. like "...%d...". If several trices form a log line only the timestamp of first trice ist displayed. (default "ms")
  -u	Short for '-unsigned'. (default true)
  -ulabel value
    	Additional user channel/tag(s) to display. This is a multi-flag switch. It can be used several times with a colon separated list of channel descriptors.
    	Example: "-ulabel this:that -ulabel also" results in adding "also", "this" and "that" as message tags. These user labels are added at the end of emitter.Tags. See also "-logLevel".
  -unsigned
    	Hex, Octal and Bin values are printed as unsigned values. For signed output use -unsigned=false (default true)
  -v	short for verbose
  -verbose
    	Gives more informal output if used. Can be helpful during setup.
    	For example "trice log -p JLINK -v" is the same as "trice log -p JLINK" but with more descriptive output what could be helpful during setup.
    	This is a bool switch. It has no parameters. Its default value is false. If the switch is applied its value is true. You can also set it explicit: =false or =true.
sub-command 'a|add': Use for adding library source files containing already trice IDs to your project.
#	It extends the ID list from these source files but does not change the source files, even if they contain Trices without IDs.
#	Already used IDs are reported, so you have the chance to remove them from til.json and your project and then do "trice add" again.
#	This way you can make sure to get the new sources unchanged in your list, even they contain trice IDs already.
#	Afterwards the newly added library source files are treated as regular project files. If you do not edit them, they stay unchanged.
#	If in one of your project files a trice from the library occurs again, like "trice( iD(123), "Hi!");" in a lib file and "trice( "Hi!");"
#	in a project file, it will get a different ID in your project file because of the used location information.
#	The "add" sub-command has no mandatory switches. Omitted optional switches are used with their default parameters.
#	Example: 'trice add': Update ID list from source tree.

    	Source dir or file, It has one parameter. Not usable in the form "-src *.c".
    	This is a multi-flag switch. It can be used several times for directories and also for files.

    	Short for '-idlist'.
    	 (default "til.json")
  -v	short for verbose

    	"filename": Any other string than "auto", "none" or "off" is treated as a filename. If the file exists, logs are appended.
    	All trice output of the appropriate subcommands is appended per default into the logfile additionally to the normal output.
    	Change the filename with "-logfile myName.txt" or switch logging off with "-logfile none".
    	 (default "off")

sub-command 'i|insert': For updating til.json and inserting IDs into source files.
#	"trice insert" will parse source tree(s) for new or changed TRICE macros, modify them appropriate and extend the JSON list.
#	This command relies on existing til.json and li.json files. The li.json file is used as reference and generated new during insert.
#	Without li.json the insert command assigns new IDs to all found trice macros, because it cannot assign files to them, and extends 
#	the til.json file accordingly. That is for safety, because the insert command acts in multiple files in Go routines parallel. 
#	If you lost the li.json file, you can run "trice add" first, to re-generate a new li.json and then execute "trice insert".
#	With an empty til.json file, the insert command re-creates a new til.json (and a fresh li.json) from the source code.
#	If the insert command finds an ID for a trice inside the sources, used already for an other trice inside til.json, it reports that
#	and assigns a new ID into the source file, adding it to til.json as well.
#	The "insert" sub-command has no mandatory switches. Omitted optional switches are used with their default parameters.
#	The switch "-src" is optional (default is "./") and a multi-flag here. So you can use the "-src" flag several times.
#	Example: 'trice i -src ../A -src ../../B': Parse ../A and ../../B with all subdirectories for TRICE IDs to update and adjusts til.json
  -IDMax value
    	Upper end of ID range for normal trices. (default 7999)
  -IDMethod string
    	Search method for new ID's in range- Options are 'upward', 'downward' & 'random'. (default "random")
  -IDMin value
    	Lower end of ID range for normal trices. (default 1000)
  -IDRange value
    	This allows tag specific routing in the target code.
    	This switch has one parameter string and is a multi-flag switch. It can be used for each Trice tag. Example:
    	Assign error tag Trice IDs in the range 10-99 and msg tag IDs in the range 100-199:
    	"trice insert -IDRange err:10,99 -IDRange msg:100,999" (overlapping ID ranges are forbidden)
    	All other trice tags get IDs from the -IDMin, -IDMax range. The used -IDMethod is the same for all tags.
    	For example you can have all trice messages in direct mode over RTT but err & msg tagged trices additionally
    	in deferred mode over a serial port and, if you need, store all error tagged Trice logs additionally in the Flash memory.
    	You need to configure the target code in your triceConfig.h accordingly (search trice code for MIN_ID):
    	Use "#define TRICE_UARTA_MIN_ID 10" and "#define TRICE_UARTA_MAX_ID 999" for example. (default "")
  -a value
    	Short for trice() aliases.
  -addParamCount
    	Extend TRICE macro names with the parameter count _n to enable compile time checks.
  -alias value

    	recognized as equivalent to a trice() call. (default none)
    	 (default none)
  -cache
    	Use "~/.trice/cache/" for fast ID insert (EXPERIMENTAL!). The folder must exist.
  -defaultStampSize int
    	Default stamp size for written TRICE macros without id(0), Id(0 or ID(0). Valid values are 0, 16 or 32.

  -e value
    	Short for exclude.
  -exclude value
    	Exclude dir or file, It has one parameter. Not usable in the form "-exclude *.c".
    	This is a multi-flag switch. It can be used several times for directories and also for files.

    	 (default "li.json")
  -liPath string

    	 (default "base")
  -locationInformation string
    	The trice location information file.
    	The specified JSON file is needed to display the location information for each ID during runtime.
    	It is regenerated on each add, clean, or insert trice run. When trice log finds a location information file, it is used for
    	log output with location information. Otherwise no location information is displayed, what usually is wanted in the field.
    	This way the newest til.json can be used also with legacy firmware, but the li.json must match the current firmware version.
    	With "off" or "none" suppress the display or generation of the location information. See -tLocFmt for formatting.
    	 (default "li.json")
  -s value
    	Short for src.
  -sa value
    	Short for triceS() aliases.

    	 (default none)
  -skip
    	short for skipAdditionalChecks
  -skipAdditionalChecks
    	No parameter count checks, when this flag is true.
    	This reduces the processing time by a few percent but does not detect wrong parameter counts, anyway the compiler would complain.
    	Add this flag for script speed-up, when not editing the sources. Alternatively consider the -cache switch.
    	This is a bool switch. It has no parameters. Its default value is false. If the switch is applied its value is true. You can also set it explicit: =false or =true.
  -spaceInsideParenthesis trice(<space>iD(<space>123<space>), "...);
    	Add space inside Trice braces: trice(<space>iD(<space>123<space>), "...);. Use this if your default code auto-formatting is with space inside braces.
  -src value
    	Source dir or file, It has one parameter. Not usable in the form "-src *.c".
    	This is a multi-flag switch. It can be used several times for directories and also for files.
    	Example: "trice insert -dry-run -v -src ./_test/ -src pkg/src/trice.h" will scan all C|C++ header and
    	source code files inside directory ./_test and scan also file trice.h inside pkg/src directory.
    	Without the "-dry-run" switch it would create|extend a list file til.json in the current directory.
    	 (default "./")
  -til string
    	Short for '-idlist'.
    	 (default "til.json")
  -ulabel value
    	Additional user channel/tag(s) to display. This is a multi-flag switch. It can be used several times with a colon separated list of channel descriptors.

  -v	short for verbose
  -verbose
    	Gives more informal output if used. Can be helpful during setup.
    	For example "trice log -p JLINK -v" is the same as "trice log -p JLINK" but with more descriptive output what could be helpful during setup.
    	This is a bool switch. It has no parameters. Its default value is false. If the switch is applied its value is true. You can also set it explicit: =false or =true.
  -w	Short for (white)spaceInsideParenthesis or "wide".
sub-command 'c|clean': Set all [id|Id|ID](n) inside source tree dir to [id|Id|ID](0). Remove all iD(n).
#	All in source code found IDs are added to til.json if not already there. Inside til.json differently used IDs are 
#	reported and just cleaned inside the source files. The existing li.json is updated/extended. 
#	The switch "-src" is optional (default is "./") and a multi-flag here. So you can use the "-src" flag several times.
#	Example: 'trice clean -src ../A -src B/x.c': Sets all TRICE IDs to 0, or removes them, in folder ../A. and file B/x.c
#	EXPERIMENTAL! The command itself works reliable, but a sophisticated editor will detect inconsistencies with removed IDs.
#	EXPERIMENTAL! With "#define TRICE_CLEAN 1" inside "triceConfig.h" these displayed "errors" are suppressed.
#	EXPERIMENTAL! All files including trice.h are re-compiled then on the next compiler run, what could be time-consuming.
#	In difference to "trice zero", Trice function calls get iD(n) removed. Example: "TRice( iD(88), "hi);" -> "TRice("hi);"
