Hi Elias,
just loop around user_commands:
*loop(u, user_commands.size())
{
user_commands[u].prefix ... // the command
user_commands[u].apl_function ... // the APL function called
...
}*
in SVN 250 you have to add *public: *before the declaration of
user_commands in Command.hh;
I will fix that in the next SVN. Note that the user can remove commands
and that*user_commands* is vector<>
so it is rather volatile (not to be stored elsewhere)

Right now I'm using the .def files to retrieve the list of ]-commands
(for tab-expansion). Clearly this will not be enough if there is a
facility to add new ones at runtime.
What method should I use to get a full list of these commands from
within a native function?
Regards,
Elias

Hi David, Peter,
I have added a *simple* facility for adding user defined commands
(the command being
implemented in APL (possibly as native function)). I will no go as
far as described in Dyalog's document below, however.
This could also be used for experimental commands or commands
"missing" in GNU APL.
See ]HELP or 'info apl'. SVN 250.

Hi David,
from what I hear Dyalog APL seems to be a good interpreter and I have no
problem with it.
I am only a little more conservative when it comes to new and
non-standard APL features.
But Peter Teeson had ideas going into a similar direction.
I hope I didn't give the impression that I was casting aspersions on
Dyalog. They've taken APL in some new and interesting directions. All I
meant is that many of Dyalog's contributions to the language tend to be
outside of the canon of ISO/IBM APL 2.
One question that I have is how the implementation of a new command
would look like.
Is it an APL function (which basically means that the command only
relieves the user
from quoting the argument of the command) or would it be implemented in
or C++
like native functions?
As I envisioned it: the former. Just some syntactic sugaring around an
APL function.
And do we know how often this feature in Dyalog was used in real life?
Its used to provide access to many of their development tools.
