Re: Broken commandline

[Hans-Peter Sorge]

    Hello Elias,
    
    that's OK.
    
    I just tried different font setting in Emacs (hoping for some
    blinking light bulb:).
    
    M-x gnu-apl-mode does not switch the keyboard. I still need
    to change it via the tray keyboard layout selection.
    btw. after the last system update the ⍝-entry (and others) in emacs
    works fine.
    
    The round trip: emacs copy / cmd line paste / cmd line copy / emacs
    paste is consistent.
    The cmd line characters have "half space, char, half space".    
    
    in apl session try:
    
          ⎕AV[168 171 182 229 230 231 232 233 234
      238 251]
    ⍚⍜⍟⍝⍲⍴⍱⌽⊖⍉⍫
            11 ⍴ '|'
      |||||||||||
    
    The composed characters take more space. line editing is garbled if
    the characters are included.
    
    
    Best Regards

When using Emacs with GNU APL, you should use gnu-apl-mode. You can download it from MELPA and you start it using M-x gnu-apl.

This should hopefully fix your problems.

Hi,

I am on Fedora 34 now (apl SVN: 1198:1472M)

The apl font partially fails to work with keyboard layout apl.

The "over strike characters" ⌽⍉⍟⍝⍱⍲ ,when entered in a terminal, appear in half....
The left half of the character is being displayed when entered.
The right half appears when space bar is being pressed.
Anny further character entered is being offset by one.

That is  ⌽[space]ABC  -> ends up as ⌽BC where space bar "overlays" character A!
The Apl-Session, terminal, emacs, vi are affected too. slikedid, Firefox are OK. 

If changing the layout via setxkbmap -layout "apl" I get ���� instead of ⌽⍉⍟⍝.
The � are being displayed the same way as described above: Left half character, [SPACEBAR] right half of the character.

I installed apl from the repository to verify the behavior - that segfaults.

The font-manager shows
⍝  APL FUNCTIONAL SYMBOL UP SHOE JOT   U+235D
So there is nothing special about this and 'normal' UTF-8 characters.

The terminal font is set to latarcyrheb-sun16 in /etc/voconsole.conf.

Changing the terminal font to either Unifont-APL8x16-12.1.02 or NotoSansMono did not help.

Emacs:
After some 'fiddling around' font changes with emacs M-x menu-set-font will display ⍝ in one go,
Char ⍝ will be displayed for different fonts - even if the font-manager does not show it.
Char ⍝ with font NotoSansMono selected will be displayed in one shot but with additional spacing to the left and right.
Char ⍝ with Unifont selected will be displayed w/o spacing.
( The console fonts and the content of menu-set-font are different...)

Hopefully some one has an idea where / how to dig deeper into the problem.

Best Regards
Hans-Peter

 

Is there / some where an experiment going on to 'improve' character composition?
