Re: [Bug-apl] New Input Mode

[Juergen Sauermann]

Hi Elias,

could actually be that your OS is echoing your input, see stty -a.
--rawCIN only prevents extra echoing of the user input inside GNU APL.

Some (but not all) input modes turn off input echo (eg. readline and --noRL).
But if, for example, readline is not installed and --noRL is not given either then
the terminal setting at the start of GNU APL may have left input echo on.

In a previous post I mentioned that removing --rawCIN fixed my problem with not seeing the 6-space prompt. I spoke too soon however. It turns out that while it works fine on Linux, on OSX I keep getting duplicated output.

Frankly, I don't quite understand why it echoes my input in the first place. That should be the job of the operating system. Even with that in mind, --noCIN does not change this behaviour.

An example when typing 'foo':

      'foo'

'foo'

foo

Hi,

as a preparation for the removal of libreadline I have created a new input mode for GNU APL.
The first shot (which is still a bit bumpy) is contained in SVN 454.

The new mode is enabled with --noRL. It will become the default (and --noRL will disappear when
the new mode is stable and readline has been removed.

The issues reported today have not been addressed yet, but will be taken care of.

The new mode is supposed to have similar (actually better) properties as readline:

- tab completion is more APL aware (⎕xx, user-defined symbols, )commands and more are considered)
- history (i.e. cursor up/down) is improved (eg. inside ∇ you can recall other function lines for editing).

Cursor key ESC sequences are currently hardwired - I will check if curses can be used instead.
