Seems like a pretty simple thing I am trying to do but it wont work.
I have some bitwise data which I want to convert into a string equivalent. So in this example I want to see if bit 0 or bit 1 is set.
Bit0 = This Text
Bit1 = That Text
This search works perfectly
sourcetype=blah | eval desc=if(floor(bitData)%2>0,"This Text, ","") | eval desc=desc+ if(floor(bitData/2)%2>0,"That Text, ","") | table _time, bitData, desc
Now I actually have 16 bitfields and want to reuse this eval chain quite a bit so thought I would make a macro out of it.
However this does not work
Macro definition
eval desc=desc+ if(floor($bitField$/2)%2>0,"That Text, ","") | eval desc=desc+ if(floor($bitField$/2)%2>0,"That Text, ","")
This search does not work though
sourcetype=blah | `myMacro(bitData)` | table _time, bitData, desc
I get the errors
Error in 'SearchParser': Missing a search command before ' '.
Unknown search command 'gen'.
What gives here?
Finally worked it out. Turns out you cannot have newlines in macros but you can in a search.
So my example above was not entirely correct it should have been.
Working search
sourcetype=blah |
eval desc=if(floor(bitData)%2>0,"This Text, ","") |
eval desc=desc+ if(floor(bitData/2)%2>0,"That Text, ","") |
table _time, bitData, desc
Macro that doesn't work
eval desc=desc+ if(floor($bitField$/2)%2>0,"That Text, ","") |
eval desc=desc+ if(floor($bitField$/2)%2>0,"That Text, ","")
Macro that does work
eval desc=desc+ if(floor($bitField$/2)%2>0,"That Text, ","") | eval desc=desc+ if(floor($bitField$/2)%2>0,"That Text, ","")
I have them all on newlines as there are 16 rows for the entire macro and I wanted it to be readable and easy to edit.
So its a bit inconsistent that newlines are allowed in a search but not in a macro. Should I submit this as a bug?
Thanks to those that tried to assist.

The fields in a macro are named. You need to pass the field into the macro like this :
sourcetype=blah | `myMacro(bitData=bitData)` | table _time, bitData, desc
That middle section would be
| myMacro(bitField=bitData)
There doesn't appear to be anything wrong with your syntax. Click the blue [i] next to the printer icon on the right of the search bar, after executing your search. Scroll down to eventSearch to see how your macro is being expanded in the search. It's likely a typo.
