Ann: P2Ada (v.22-Dec-2002)

Ann: P2Ada (v.22-Dec-2002)

[Gautier direct_replies_not_read]

Hello. Recently G. A. Craig Carey (mostly) and I reworked P2Ada, a
command-line Pascal to Ada translator.

P2Ada is now able to translate large sources. Depending on
the sources, the pre-work needed to have a successful translation and
the rework after translation have been significantly reduced.

URL: http://www.mysunrise.ch/users/gdm/gsoft.htm#p2ada

Two recent "success stories":
  - porting of MAS (Modula-2 Algebra System, 73 kSlocs)
      by using Mod2P and P2Ada
  - porting of the Numerical Recipes in Pascal.

Bugs fixed: a lot!

Some of the new features:

- Support for Sqr, Odd, Eof, Eoln, Read, ReadLn, Ord, Chr (standard Pascal)
     and type Double
- For Borland integers, a transitional package is provided.
- Turbo Pascal 7's CONST parameters translated.
- Set expressions better translated (in form of array of Boolean).
- A procedure Dispose is created for each access type.
- For variables of a structured type, P2Ada creates an ad-hoc type for them.
- Option to translate a "var" parameter by "var" instead
     of "in out": it is wrong but caught by the Ada compiler for the rework.
- Name of procedures and functions put after "end".
- Smarter recognition of variables (array elements, record fields,...)
- Bigger buffers for translating large sources.
- Added casing of Ada keywords (upper/lower/neutral).

Enjoy!

What about a tool that goes the other why around ? Ada to Pascal ?

Probably the place to ask would be a Pascal newsgroup.

D De Villiers:

Do you need one ? It depends on whether you wish (1) a human-readable
output form to rework or (2) a mean to compile Ada sources on a certain
environment where there is only an interesting Pascal compiler and
no Ada compiler.
A tool for (1) is quite a challenge to find, a bit like a kit to
transform your recent car into a brand old VW Beetle...
For (2) it may be better to use C than Pascal as intermediate language.
For (1) and (2) you have to precise the dialect of Pascal, of course.

How well can P2Ada handle BCD (Binary Coded Decimal) in Turbo Pascal? 
I have a very old program written in Turbo Pascal with BCD and I am 
interested to have it translated to Ada. About 17KSLOC.
