Package for text filtering?

Package for text filtering?

[Preben Randhol]

Hi

I need to filter a resultfile produced by a program (only executable
availabel) so I can get the different results I'm interested in. I need
to do it in Ada (so no hints about python, perl etc ;-) ) but I thought
that there must be some packages (besides the GNAT pacakges) available
to ease the filtering.

So links/hints most welcomed.

GNAT includes nice string pattern matching packages. The best for me is 
GNAT.Spitbol.

There is also Open_Token out there.

AdaCL (http://adacl.sourceforge.net) has a powerfull - yet easy to use -
text filter library.  And it's a class library - if what you need is
missing  you can extened it.

Look at the sarDO source to see how it works:

OK, besides GNAT's spitbol:

http://www.dmitry-kazakov.de/ada/components.htm
- this project contains parsers for elaborated infix expressions of any
kind (in case your output has something like 2+5*(3-6))

http://www.dmitry-kazakov.de/ada/strings_edit.htm
- this is a set of simple tools for parsing and formatting strings

http://www.dmitry-kazakov.de/match/match.htm
- this is pattern matching, though written in K&R/ANSI C, it has Ada
interface.

While I have not used this...I strongly recommend taking a look at it 
since I think it was designed with what you have in mind.

I forgot to mention: the I/O modules are also classes and can be replaced
with specialised versions.

Currently available:

Textfile_1 => Textfile_2    where both files can be the same.
Textfile => Standart_Output   as part of the CGI package.

Great I'll check it out!

Thanks all for the feedback!

The PragmAda Reusable Components include regular expression matching. 
There's an example program, strmsub, that's a stream editor and was 
pretty easy to create.

I have used Aflex and Ayacc.  I had an old Ada 83 version I had to doctor up 
to work with GNAT (several years ago).  It looks like there are versions 
available on AdaPower:

http://www.adapower.com/index.php?Command=Class&ClassID=Utilities&Title=Ada+Utilities

There is a little bit of a learning curve, but they are powerful tools.
