[Bug-apl] Fwd: Re: Parsing error?

[Juergen Sauermann]

Hi David,

as far as I remember, I have removed the use of readline in GNU APL some time ago.

There is also a very good document written by Peter Teeson in the doc directory
that explains building GNU APL on MACs.

Thanks Christian to show new version ( and also show me how to build ).

I was able to get source code from SVN trunk and manually build ( or use brew install --build-from-source ) successfully, but missing readline library.

Yes, I am using Mac and brew ( that's why my GNU APL is old; version 1.4 from brew install; and no brew formula yet for 1.5 ).
I already installed readline ( brew install readline ) before.

Tried set up LDFFLAGS and CPPFLAGS to point to directory of readline, but still no luck.

And there seems no configuration option about setting readline directory ( only option to without readline )

I saw there is a ax_lib_readline.m4 seems to detect existence of readline library, but cannot figure out how to force the flag to true.

Anyone is using Mac ( + brew ) and successful to build SVN trunk GNU APL with readline library? Can you enlighten?

Thanks,

David

Hi,

I am newbie on APL, so I am not sure below is a bug or not :-)

      v ← (1 2 3) (4 5 6)
      f ← {1+⍵}
      f (⊂ 1 0 1)/¨v
SYNTAX ERROR
      f(⊂1 0 1)/¨v
      ^          ^

However, adding parentheses works:
      f((⊂1 0 1)/¨v)
 2 4  5 7 

But f is function, with APL's right-associative rule, it should no need parentheses for f.

( Tested with TryAPL.org without parentheses and work without error )

BTW. here is my version info:
~ $ apl -v
