Hi Wojciech,

I am looking in my copy of V4, does not seem to contain `Def.Mod'. Where it 
comes from in your version?

$ tar -tzf ProjectOberon.V4.tar.gz | grep Def.Mod

Many thanks

How about Def.Mod which is available under Oberon System V4? 

Right click on "Def.Show Def.Mod" opens a new viewer with the following: 


PROCEDURE Show; (* ( "*" | "^" | name ) [ "\P" ] --P option enforces plain 
text style *) 
END Def. 
Def.Show Documents.Mod opens the following viewer: 

DEFINITION Documents; 
profile = "Documents.Profile"; (* on startup all openers contained in this 
file are registered automatically *) 
pattern-, cmd-: ARRAY 32 OF CHAR; 
next-: Opener 
openers-: Opener; 
PROCEDURE Open; (* ^ | name Opens the specified file with the registered 
opener, if no specific opener is found for the extension of the file, Edit.
Open is used. *) 
PROCEDURE RegisterOpener (pattern, command: ARRAY OF CHAR); (* Registers the
opener command for the pattern. Openers that are registered earlier can be 
overwritten by (more specific) openers registered later. *) 
PROCEDURE RegisterOpeners; (* ^ | filename Registers all the openers 
contained in the specified file. Their precedence is as they appear in the 
file. *) 
END Documents.

I am thinking of a simple tool that could extract definition info from *.Mod
and produce respective *.Def file. Definition files can be quickly looked 
at, to remind a programmer of the interface *.Mod modules export. 

While on Linux one could use grep 
$ grep PROCEDURE\ * *.Mod.txt 

to obtain info at least about procedures, but how about exported types and 

I am looking for a recommended way how to simply code such a tool, is it a 
good idea to use `ORP' parser somehow for the task? I prefer to code it 
simple, does not have to be perfect, but should carry the idea.
