Tools Generating Ada

Tools Generating Ada

[vincent.diemunsch]

Hello everybody,

I have a question regarding Ada Code Generation tools, like Aflex / Ayacc for instance. How can I insert them into the automatic build process ? I use GNAT GPL, so is it possible to create a GPRBuild project that generates Ada files from an AYacc source and then compile the Ada sources ? Do I need to use a make file ? Where can I find examples ?

Regards,

Vincent

You should be able to do it with GPRBuild.  I haven't tried yet.  I use
make files for that kind of problems.  Some examples:

Not really what's the OP want to achieve. The goal is to generate a set
of sources from a project file (using aflex/ayacc or any other
generator) and make the newly generated files part of the current
compilation.

I'm not sure this is possible...

Thanks all for your responses.
I certainly will use a makefile, but I hoped someone has used GPRBuild to do that, defining a new language, and using a "subsystem" or "subproject" for code generation. But as Pascal mentioned the big question is will GPRBuild handle correcty the fact that some Ada source files have been modified by the subproject. It needs a try !

Vincent

The Ayacc/Aflex tools generate Ada source files (1) which are for instance an Ada code generator (2). So Ada sources are generated at two levels!
So not sure what you want to do exactly...

The parser (1) needs to be compiled only when you change the .y / .l files (parser grammar / lexer).

Code generated at (2) needs to be compiled when the input side of the code generator has changed.

You can for instance configure the code generator to call gprbuild each time the generator has finished generating the Ada sources.
As an example where the latter is automatized, there is GWenerator ( see @ http://sf.net/projects/gnavi/ ) which does all that automatically.
You can continue using the GNAT Programming Studio while letting GWenerator running in the background.
For other examples, with no automatic activation, I have also two other Ada code generators and a few other ayacc tools if you are interested (all open source).

Yes; you have to write an XML file to tell gprbuild about the tool.

I did this for Auto_Text_IO, which produces *.Text_IO packages from Ada
packages.

The process is not well documented, and the XML file often needs
tweaking with new releases of the GNAT compiler; I submit a bug report
to find out how to tweak. I don't recommend doing this without an
AdaCore support contract. Unless you have read and understand all of the
gprbuild source :).

That takes two projects, to keep the source information distinct.

>Do I need to use a make file ? 

No, the project that compiles the Ada code can 'with' the project that
produces the Ada code.

However, gprbuild doesn't always get the dependencies right; sometimes
you have to run it twice.

Here. This works with GNAT 7.1.2, and probably with GPL 2013:

Thank you very much for your complete response !
I'll try this, maybe with the help of AdaCore's support.

By the way, does GPRBuild creates "ali" files for an external tool ?
If not, then how can it knows what the dependencies ares ?
Does your tool creates an ali file ?

Kind regards,

Vincent

gprbuild never creates an ALI file. The compiler does.


>  If not, then how can it knows what the dependencies ares ?

In your case, you would generate a Makefile fragment showing the dependencies.
I have written a gem on the subject, but I do not think it has been published yet
on AdaCore's website. Perhaps next month.

No, the ALI is only modified by the compiler. gprbuild use it to call
the binder and the linker. For sure the linker does not even knows about
the existence of the ALI file.

The builder (gnatmake or gprbuild) reads the ALI files
(or takes note of the fact that some ALI files don't
exist) in order to decide what needs to be compiled.

The compiler writes the ALI files.

The binder reads the ALI files to check that everything
is up-to-date and consistent (but this step is normally
skipped when you use the builder, because the builder
already makes sure of that).  The binder does not write
on the ALI files.

ALI files are specific to GNAT/Ada.  The linker is language
independent, so it doesn't know anything about ALI files,
and neither reads nor writes them.

As others have pointed out, only the compiler generates ali files. But
gprbuild can call the compiler, so the answer is "yes, it can be used
for that".

However, you need to specify different compilation switches; the ali
files contain slightly different information when intended for ASIS than
when intended for the binder and linker. (auto_text_io is an ASIS
application).

auto_text_io can call the compiler to create the ali files it needs, or
you can use gprbuild to generate the ali files for auto_text_io; it
depends on your overall flow.
