[Oberon] FPGA Oberon - Definition Module Tool

Wed Mar 29 13:48:55 CEST 2017

Hi Christopher,

Thank you for useful guidelines, I will follow closely. 

I am also reading Oberon-07 report outlining differences to 02, also Oberon
07 at a glance giving distilled info.

I have somehow managed to convert `Splines.Mod' that is referred to in 
Applications chapters of the project book.

Many thanks

Tomas

"Hi Tomas,

Note that Def.Mod is written using Oberon-2. If you want to use it on 
Project Oberon you will have to modify it so that it conforms to the Oberon-
07 language report. It would make a good mini-project for you to do to 
become more familiar with Project Oberon.

Here are a couple of tips to get you started:

1. You will need to implement a function named CAP that converts characters 
in the range "a" to "z" to the corresponding capital letter in the range "A"
to "Z".

2. You will need to refactor any code that contains RETURN statements 
anywhere other than the end of a function PROCEDURE. 

e.g. replace the following:

BEGIN
IF sym = eot then RETURN END;
sym := none; ln := line
...
...

with:

BEGIN
IF sym # eot THEN
sym := none; ln := line
...
...

3. COPY is no longer required to copy character arrays. You can just use an 
assignment statement:

e.g. COPY(x, v) can be written as v := x

Chris

Hi Thomas,

what about this one: https://sourceforge.net/p/oberon/oberonv4/ci/master/
tree/UV4/Def.Mod

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
Tomas

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: 

DEFINITION Def; (* CAS *) 

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

DEFINITION Documents; 
CONST 
profile = "Documents.Profile"; (* on startup all openers contained in this 
file are registered automatically *) 
TYPE 
Opener = POINTER TO RECORD 
pattern-, cmd-: ARRAY 32 OF CHAR; 
next-: Opener 
END; 
VAR 
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.

Hi, 

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 
variables? 

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.
