Re: [Bug-apl] 950 )HELP Issue, and mem.cc

[Juergen Sauermann]

Hi Fred,

tahnks, I fixed the )HELP issues, SVN 951.

Not sure what you mean by releases. If it is major releases like 1.6, 1.7... then
the corresponding release announcement normally tells what the major improvements
are. The next finer granularity is SVN commits, and for them I consider the SVN commit
text to be more useful than a separate CHANGES.txt file. You can use the svn log
command, either for individual files or for directories to retrieve these messages.

I will be AFK for almost two weeks from now and will have a closer look at mem.cc
when I am back. Please remind me if I should forget that.

Best Regards,
Jürgen

In 950 (and going back a few releases) Command.cc has broken )HELP.

At (around) line 150, add

if (!strcmp(command, ")HELP")) return false;

without this, things like ")HELP +" (or whatever) won't work.

Second: )HELP doesn't actually behave well with NATIVE functions. At (around) line 962,

try

if (ufun) ufun->help(CERR);

instead of

Assert(ufun);

Now, it would be useful to implement a "help" option to NATIVE -- but I haven't done that.

As a side-note, it would be useful to have a CHANGES.txt file detailing the changes from a release

to the next.

Find attached a first cut at shared memory support (mem.cc). It allows mmap() of a region

(get the file handle from fopen), and supports floating, integer, character, complex vectors

of different sizes transferring from GNU APL to and from the shared memory region. I am

working with this currently, and when I get some experience will try to graft into some

of the primitives. But this gives an idea of what I was talking about at the beginning of the

month.
