Re: [Pdl-general] History list and command editing in perldl

[Chris Marshall]

Will-

I'm glad you got things going with command
line editing support for perldl.  There is
also an updated PDL shell called pdl2 which
provides some improved support for completions
of various types if you have the needed module
dependencies installed.

If you try to run pdl2 and the dependencies
are not there, it should quietly start up
the perldl shell instead so you can have one
stop shopping for the PDL shell.

Enjoy!
Chris

Hello piddlers,

/*perldl*/is one great prototyping tool, and I am making great 
progress understanding and mastering PDL running it in macOS, but thus

been a total bust. The docos say the command line editor is 
emacs-like. I would prefer vi but /*any*/command line editing is 
welcome, given how I am using perldl to learn PDL. However, I cannot 
enable the history list nor edit a previous line other than doing very 
precise cut and paste. Here is the initial announcement when I start 
perldl:


$ perldl

Notice, *ReadLines*is enabled.

And here is what I get with the l command, 'l', not '1';

"Term::ReadLine::Stub" at 
/Users/carly/perl5/perlbrew/perls/perl-5.20.3/bin/perldl line 313, 
 line 2.


What am I missing? What Perl/PDL modules must be present? Getting 
history and command editing working would truly make perldl an 
effective learning tool.


Thanks and regards,
Will Schmidt

Re: [Pdl-general] History list and command editing in perldl

[Karl Glazebrook]

Hi Will

You could try the SciPDL download which lives within it’s own kitchen sink and 
likely won’t break on new MacOS. (Also includes GNU::Readline)


/usr/bin/python includes an editable command line, why can’t this be built in 
to perl? I find the whole Term::Readline::XX thing confusing. What is the 
Term::ReadLine (and Term::Readline::Perl ?) that come with perl?

Re: [Pdl-general] History list and command editing in perldl

[William Schmidt]

That did it. Man, having an editable history list is primo. I think this is
another example of how badly macOS High Sierra sucks. Apple now wants us to
install 10.13.4 which will again break everything that was compiled with
the 10.13.3 Xcode libs, as the download includes new libraries and command
line tools. That's it for me. I will live with 10.13.3 as long as I own
this Pro. Now, should I try to clean out all the cruft I put into my
perlbrew by hacking, as in removing Term::ReadLine::Gnu which I --forced,
to no avail. I hate leaving installed the dregs of failed hacking. Thank
you Chris and Craig for your help.

I suggest installing Term::ReadLine::Perl which
is a pure perl implementation of the readline
capability.  I use it on the windows PDL since
there is no GNU readline for microsoft com windows.

Re: [Pdl-general] History list and command editing in perldl

Progress, but no cigar, yet...

brew link --force readline

I downloaded the latest library and then attempted to reinstall
Term::ReadLine::Gnu, with the following error in the build log:

This part seems correct:

Found `/usr/lib/libtermcap.dylib'.
cc -I/usr/local/opt/readline/include -fno-common -DPERL_DARWIN

<<>>

This part seems incorrect:

Your terminal 'TERM=xterm-256color' does not support enough function.
Check if your environment variable 'TERM' is set correctly.

I never set TERM explicitly so I don't know what that module is expecting
or whether my Mac has the right stuff. I do have the latest XQuartz,
2.7.11, installed.

Re: [Pdl-general] History list and command editing in perldl

You may have to manually install the Gnu Readline library.  It’s becoming 
enough of a pain in the butt to get installed, that an Alien::ReadLine might be 
called for...

Hmm,

Tried that.

$ cpanm Term::ReadLine::Gnu
Term::ReadLine::Gnu is up to date. (1.35)

Does it require config or enabling?
