When cross-compiling for Android, the configure script seems to detect that
the shm_functions are available, when they are actually not.
If I manually undefine HAVE_shm_open, then the build works.

In Svar_signals.hh, there is a reference to the error code EBADRQC. This
symbol does not exist on OSX. There should be a configure test to see if
this is defined, and if not, perhaps use EINVAL instead?

Hello Jürgen,
What is the recommended way to configure the paths now? I need to be able
to specify the prefix path as well as the path to the workspace when
running GNU APL as a library (in Android).
Note that I don't know the path until the program actually starts, but I
have access to it before

Nice! I'll try it out on Android shortly.

It could be argued that it makes some sense on mobile, since native
libraries on Android is messy at best.
That said, I intend to provide a built-in API to support various
Android-specific features. Some of those will probably be more useful than
shared variables, maybe.

I agree with the general point, but is it really executed that often?
(good) APL code tends to do a lot with few operations. It would perhaps
make sense to benchmark how many comma functions are called in a typical
program?

The standard says the following:

I have to agree with Blake here. Ideally there should be a call to
getenv("HOME") and if that returns non-NULL, then use the .apl_history in
$HOME/.apl/apl_history or something like that.
If it returns NULL, well, then fall back to current directory I suppose.
I could make the Emacs mode use the

I was playing around with solving the Dyalog challenge, and I found them

The goal was to write a lambda function that given a single integer,
returns a list of the Fibonacci series up to that number.
The only way I can think of solving it is by using a full

When I build and install GNU APL, I specify
--prefix=/home/elias/src/apl/dist. I then expect the PSYS to be
/home/elias/src/apl/dist/lib/apl/wslib*[0-9]*.
Now, typing )LIBS at the prompt gives me: /usr/local/lib/apl/wslib*[0-9]*.
This is not correct, is it?

There is already the SIGINT signal which is processed by GNU APL to

It would be nice to be able to access the values of ⍵ and ⍺ (and I suppose

I.e, I'd like to following to return the value 1100:

In other words, the ⍵⍵ in the inner lambda would refer to the value 100

Most modern (and some not-so-modern) languages have a standard way of
attaching documentation to functions and other symbols. For example, in
Java documentation looks like this:
*/***

* * is a normal comment that comes
f the last example:
add1 ← { "Add one to the right-hand argument." ⊢ ⍵+1 }

Interesting. Given the following definition of pp:
∇Z←X pp Y
⎕←'comparing'
⎕←' X=' (8⎕CR X)
⎕←' Y=' (8⎕CR Y)
Z←X≡Y
∇
I get the following output:
*(⊂'foo') pp¨ (,⊂'foo')*
comparing
X= ┌─┐
│┌→──┐│
││foo││
│└───┘│
└∊┘
Y= ┌→
Jürgen,
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 reason for this is that in my SQL∆WithTransaction call, I need to call
the rollback function if there is an error, but then I want to
This information is already stored. The Emacs mode uses this when
navigating to definition of a function.

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...

Jürgen,
I have updated the SQL module in the git repository. First and foremost I
have renamed ResultValue to SqliteResultValue to better illustrate that
it's only required by the SQLite provider. Secondly, I've added
documentation to the sql.apl library.
This integrates neatly with the new docum

The Emacs mode reads this information using C++ code.

And it's completed. C-c C-h on a function should now display its
documentation (if there is one).
