Re: A curious bug...

[Elias Mårtenson]

The del editor in the Emacs mode is completely different from the one on the commandline.

What happens is that the emacs mode detects the del character and opens its own window. Once you type C-c C-c, it sends the code to GNU APL. Something is being processed incorrectly on the APL side.

Hi Emmanuel,

thanks, fixed in SVN 1699.

Thanks a lot ! This works.

But now, I have another problem :  the gnu-emacs interface no longer supports using the del editor : one can open it fine, but sending the devinition with C-c C-c fails : the APL interpreter complains receiving "Unknown APL character: \342 (U+FFFFFFE2)". Illustrated in this sceen dump :

Note that this does not happen with the apl interpreter on the command line (I pasted the APL lines copied from the emacs buffer) :

Quite annoying (emacs and gnu-apl-mode being by far the easiest to use interface on my laptop, thanks to APL-Z input mode...).

Back to the distributed .deb... Attached : configuration/compilation logs.

HTH,

It's a vanilla numeric matrix :

It seems that trying to format it fails! This :

      test←4 0 7 ¯3 7 ¯4⍕sample

never returns, and the apl process eats 100% of the time of one of my 8-core CPU. The only way to exit is to kill the emacs buffer where it runs : emacs asks for permission to kill the process (see below).

Setup : Laptop : core i7, 16 GB RAM, Debian testing, apl_1.8-1_amd64.deb downloaded from the Gnu mirror. APL runs from emacs via the inferior-mode created by gnu-apl (from the gnu-apl-mode package).
