could be done automagically, much like the numbering in libeay.num and
ssleay.num. The solution works as follows:
- New object identifiers are inserted in objects.txt, following the
syntax given in objects.README.
- objects.pl is used to process obj_mac.num and create a new
obj_mac.h.
- obj_dat.pl is used to create a new obj_dat.h, using the data in
obj_mac.h.
This is currently kind of a hack, and the perl code in objects.pl
isn't very elegant, but it works as I intended. The simplest way to
check that it worked correctly is to look in obj_dat.h and check the
array nid_objs and make sure the objects haven't moved around (this is
important!). Additions are OK, as well as consistent name changes.

objects.txt syntax

------------------
|
|
|
|
To cover all the naming hacks that were previously in objects.h needed some
|
|
kind of hacks in objects.txt.
|
|
|
|
The basic syntax for adding an object is as follows:
|
|
|
|
1 2 3 4 : shortName : Long Name
|
|
|
|
If the long name doesn't contain spaces, or no short name
|
|
exists, the long name is used as basis for the base name
|
|
in C. Otherwise, the short name is used.
|
|
|
|
The base name (let's call it 'base') will then be used to
|
|
create the C macros SN_base, LN_base, NID_base and OBJ_base.
|
|
|
|
Note that if the base name contains spaces, dashes or periods,
|
|
those will be converte to underscore.
|
|
|
|
Then there are some extra commands:
|
|
|
|
!Alias foo 1 2 3 4
|
|
|
|
This juts makes a name foo for an OID. The C macro
|
|
OBJ_foo will be created as a result.
|
|
|
|
!Cname foo
|
|
|
|
This makes sure that the name foo will be used as base name
|
|
in C.
|
|
|
|
!module foo
|
|
1 2 3 4 : shortName : Long Name
|
|
!global
|
|
|
|
The !module command was meant to define a kind of modularity.
|
|
What it does is to make sure the module name is prepended
|
|
to the base name. !global turns this off. This construction
|
|
is not recursive.
|
|
|
|
Lines starting with # are treated as comments, as well as any line starting
|
|
with ! and not matching the commands above.
