Re: [Bug-apl] Ctrl-D and )off

[Juergen Sauermann]

Hi,

I have added a parameter CONTROL-Ds-TO-EXIT to the preferences file.

The default 0 is the current behavior. A positive number tells how many ^Ds in a row
will exit the interpreter. SVN 516.

I agree that this is annoying, especially for new and casual users.

The only good reason I can think of for APL not exiting on Ctrl-D is
that if you accidentally hit Ctrl-D, you could accidentally lose the
whole contents of your workspace.

At least in GNU APL, if you hit Ctrl-D you get a message telling you
how to leave the interpreter.

Hello

Is there a reason why GNU APL does not exit on EOF, aka. Ctrl-D on cooked
input? Every shell and interpreter I have ever used does so by default.

Maybe there are people who are used to typing "exit" or "logout" by hand,
but for those of us who have always hit Ctrl-D to exit from any interactive
line-oriented application, GNU APL's persistent refusal to do so is quite
annoying ;-)

Even Bash, when it has background jobs still running (that would become
orphaned or receive sighup) will print a warning at the first Ctrl-D, but
comply without further ado at the second one.

If there is no valid reason, meaning that it's just some historic behaviour
of APL interpreters, I would suggest changing it so that it's more coherent
with the rest of GNU CLI tools. If instead there are valid reasons, could
there be an option in the preferences file to enable it?
