FW: gnu m4

[Daniel Deptford]

Hello,

 

I’m not sure if this is a bug or not (probably not though – it might be a bug in the documentation though J).

 

I’m using m4 –version = GNU m4 1.4.2

 

It would appear that $1 for bar is being invoked without a parameter call, is this normal?

 

Thanks,

 

Daniel.

Hello there,

 

I’m using the gnu m4 macro processing utility, but I’ve got a little problem.  To put it simply, I want to supply macros as a parameters to other macros for them to execute with an argument list.

 

define(foo, $1)

define(bar, $1($2) )

bar(foo, fwap)

 

Now this should display just fwap by itself, as bar should invoke foo with bar’s second parameter, but it appears to be just invoking foo with zero parameters, and then printing out ($2) which expands to fwap.  So I get (fwap) instead of fwap.

 

Anyone out there who can help?

 

Cheers

 

Dan
