And of course, defining a function using *C-c C-c*
(gnu-apl-interactive-send-current-function) defines the function using the
dyadic ⎕FX as described above. The )LOAD function in GNU APL also sets it.
And there's how function navigation is implemented in the Emacs mode. :-)

Just some extra information: There is not currently (at least as far as I
know) any way you can read this information from within APL. You can,
however, set it using the dyadic form of ⎕FX:
*0 'foo.c:10' ⎕FX 'Z←aa X' 'Z←X+1'*
This specifies that the function aa was defined on line 10 of the f

I have updated the SQL module in the git repository. First and foremost I

It's most definitely supposed to (and it was written to) not require either

The thing that started this is that GNU APL was not able to compile without
the SQLite .h files. In other words, GNU APL requires SQLite. I think he
wants it to only use SQLite when ./configure finds it.

Did you mean ? Then that is actually correct. ResultValue is
specific to the SQLite provider. If SQLite support is not enabled, that
file shouldn't be compiled.
Perhaps it would be best if that file is renamed SqliteResultValue...

I apologize for the confusion, but this proposal is about capturing the
file location of a function's definition; not about the function's
comments. My lead sentence was just an indicator that the earlier
discussion of comments triggered this new line of thought...

A component file system for GNU APL has been released for GNU APL. It is
located at:
https://github.com/blakemcbride?tab=repositories
This Component File System fully conforms to:
Programming Language APL, Extended
ISO/IEC 13751:2000(E), Annex A
It is built on top of the SQL Interface by Elias
You must set errno = 0 before calling access(). Otherwise the lib_file_io
return value may be incorrect upon success.

Hi,
my favourite for code documentation is *Doxygen*. It does not currently
support APL comments but we might be able to change that. Or use one
of the existing tags like --- for *VHDL* or %%% for *Erlang*.
It would need some changes in GNU APL - multi-line comments and
proper storage of documen
Hi,
Kacper is right - it is in the standard.
But the standard merely says "Set the rest of event-message as appropriate".
The rest is rather APL2 specific. I could also argue that the current
value of the parameter
is more relevant to the exception than the original value. I have put

Elias' thread about docstrings got me to thinking about other function
metadata.
One thing that might be nice to have is for APL to record the source
location of a function's definition.
If the function is defined in a file, record the path and the line number
of the first line of the definition.
Got it. Thanks.

Hi,

The sqlite should be optional - Elias, there is a
*#include "apl-sqlite.hh"*
in *ResultValue**.hh* - that looks wrong.
*execinfo* is a separate lib on some platforms and part of *glibc* on
others.
It is OK if the test for it fails.

Whoops, this thread was about the message rather than return value.
About that, standard states that event-message is local to a context and
that ⎕ES should create an exception in caller's context, but I don't
think it's properly specified what does it exactly mean.
But the point is, that ⎕ES _is_
You can use popen() to run pwd in a shell. It'll give you the same answer
as calling getcwd() from within the APL process.
A file's presence can be probed using fstat(). A negative return value
denotes the absence of the file.
popen() and fstat() are already exposed via lib_file_io.
Take a look

Dear Juergen,
Every place that I use ⎕ES I am being forced to treat the arguments as
read-only. I also had to re-order code to account for optional arguments.
It makes for some ugly code. I hope when you add lazy copying of arrays,
the internal code to do this correctly won't be a problem.

That "return nil" is clearly a typo and a further reflection of the poor
quality of that spec. I offer the following as proof that that comment is
a typo:
1. Look at the signature of ⎕ES at the beginning of 11.5.7. It says:
⎕ES B
it does not say:

Fixed. This was a problem because when ]boxing was turned on, I kept

But it is. See sections 11.5.7 and 11.6.5.

Do you think it would be possible to implement some way of retrieving not
only the error code, but also the )MORE text from an exception inside
an ⎕EA?

the rollback function if there is an error, but then I want to
