doxygen alias to struct, class, etc - doxygen

Question

I want to create some alias that that internally creates \struct command that refers to some specific struct and adds some additional commands:
ALIASES += "thing{2}=\struct \2 \n \n \xrefitem thingList\"\" \"List of Things\" \2 this thing belongs to that \ref \1"
the alias is invoked in some normal doxy-comment:
/**
*
* \thing{SomeThing, SomeThingStruct}
*
* \brief ..sdfsdf
*/
typedef struct sSomeTag SomeThingStruct;
It mainly does that it should and also the xrefitem list is generated correctly, but i get the error:
warning: the name `\_linebr' supplied as the argument of the \class, \struct, \union, or \include command is not an input file
because it interprets the \n in the alias as second argument to the \struct keyword
How can i define my alias that it does not produce this warning?

Answer 1

See documentation about ALIASES in the doxygen documentation.
A few points directly from the documentation:
ALIASES This tag can be used to specify a number of aliases that act
as commands in the documentation. An alias has the form: name=value
For example adding "sideeffect=#par Side Effects:\n" will allow you to
put the command \sideeffect (or #sideeffect) in the documentation,
which will result in a user-defined paragraph with heading "Side
Effects:". You can put \n's in the value part of an alias to insert
newlines (in the resulting output). You can put ^^ in the value part
of an alias to insert a newline as if a physical newline was in the
original file.
We see here the usage of the equal sign (=) (corrected in the mean time, had been forgotten during copying)
the use of upper case <-> lowercase (you should now have a message: warning: Found unknown command\thing'` (corrected in the mean time)
usage of \n might be ^^
SO the alias should read:
ALIASES += thing{2}="\struct \2 ^^ ^^ \xrefitem thingList\"\" \"List of Things\" \2 this thing belongs to that \ref \1"
