Re: [Bug-apl] Keymap and underlined ⍺ and ⍵

[Elias Mårtenson]

I agree with the suggestion to implement more extensions. There are a few really interesting ones such as the power operator.

However, performance is something that needs to be worked on as well. Right now there are cases where performance deteriorates very quickly, such as when constructing and working with large arrays. Right now GNU APL is pretty much impossible to work with for 2D arrays of ten thousand rows or more.

I had to work with a million row table once, and I very quickly gave up the idea of using APL for it.

Dear Juergen,

Thanks.  If you are using the Dyalog standard then you should match my (WASD custom) keyboard, so I'll be interested in the layout once you correct ]KEYBOARD.

I am hoping you can included my WASD keyboard design and setup file with GNU APL.  This would make a high quality GNU APL keyboard available to everyone.

Lastly, as a tangent, I hoped that down the road, once GNU APL is very stable with respect to the IBM standard, you may start to add operators provided by other APL vendors - so long as they don't conflict with the IBM standard.  If you did this, you would slowly start making use of more of the currently unused APL characters.

Thanks for everything.  Your system is very usable now.  I really like it.  GNU APL contained the critical mass needed to get me back into APL after a 30 year hiatus.  I have spent a bunch of time getting my old tools up and running on your system from old printouts I had.  I pretty much have that going now.  I am looking forward to making real use of GNU APL and my old framework again.  Thanks a lot!!

Hi Blake,

these days GNU APL is following Dyalog APL because they are selling their keyboards (and
I bought one). I just had forgotten to update the ]KEYBOARD command; the config files shipped
with GNU APL should already reflect the Dyalog layout.

IBM seems to offer only APL keycaps, and Unicomp did not even bother to answer an inquiry
that I sent them.

I noticed that for the ]KEYBOARD command, the comment symbol ⍝ appears in two places; on the C key, and on the \ key.  I think, perhaps, that keeping it on the \ key and removing it from the C key makes sense for the following reason.  The Z, X, C, and V keys are often mapped to the very convenient four characters each with a quad and one of the four arrow keys (up, down, right, left) which are very useful for keyed or component file IO.

I also, regretfully, noticed that I created my custom keyboard using the Dyalog standard rather than the standard used by GNU APL.  Apparently, both the Dyalog standard, and the GNU APL standard differ from the IBM standard.  Perhaps Standard is a poor word...

Thanks.

Hi,

Fred is correct. I have updated the ]KEYBOARD command to show
the new layout (as for dyalog keyboards). ⍙ is Alt-shift-. (two keys
right from M). SVN 345.

Elias,

        My keyboard is configured to have ⍶, ⍹, and ⍷ above ⍺, ⍵ and ∊,
respectively, so that their locations are easy to remember.  I would
have
liked to placed ⍙ above ∆ but that location was already occupied by ⍋,
so I placed ⍙ above ⌊ on the 'd' key.

Any suggestions where I should put the ⍶ and ⍹ symbols on the Emacs
keymap? The ]KEYB command doesn't display a mapping for them.
