Dear all,

I'm thinking in terms of a library with prototypes something like:

a) long macOpen ( MAC_HANDLE *handle );
b) long macIoctl( MAC_HANDLE  handle, char *name, void *value );
c) long macRead ( MAC_HANDLE  handle, char *name, char *value, long maxlen );
d) long macWrite( MAC_HANDLE  handle, char *name, char *value );
e) long macClose( MAC_HANDLE  handle );

f) long macParse( MAC_HANDLE handle, char *defns );
g) long macSubst( MAC_HANDLE handle, char *src, char *dest, long maxlen );

h) long macReport( MAC_HANDLE handle );

This library could be used directly by applications which need to support
macro substitution.

A "macsub" (or "mactool"?) application would be written which would use the
above library and use a command like:

macsub a=b,c=d e=f -Iaaa -Ibbb

to parse a file like:

# comment
%include filename
%xxx = ppp
%yyy = $(xxx)
<arbitrary text containing macro references>

There would also be options to read and write specified files, control the
comment character, control the command prefix, change the macro substitution
characters etc.

Syntax would be a loose subset of corresponding GNU make syntax.

Any comments?

William
