Raku rename

[bduggan]

I'm opening this PR for the Perl 6 to Raku name change.

This draws on #53 but has a few modifications.

Just a troubleshooter for people having problem to update to raku on debian

To get the lastest version on Debian see rakudo-pkg : I had troubles to bootstrap with Z because I messed all my binaries, the last link restored peace on Intel or AMD

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 379CE192D401AB61
echo "deb https://dl.bintray.com/nxadm/rakudo-pkg-debs `lsb_release -cs` main" | sudo tee -a /etc/apt/sources.list.d/rakudo-pkg.list
sudo apt-get update && sudo apt-get install rakudo-pkg

PS : My initial error before unwinding that was on Net::ZMQ4

Cannot find method 'is_dispatcher' on 'BOOTCode': no method cache and no .^find_method
home#sources/FC1DE5470FF5B7D8A301F6A4F740D2AB33836E50 (Net::ZMQ4::Context):5
home#sources/542A37D8381253B57190B2E0A2580627D9EB8B49 (Net::ZMQ4):6

Aposteriori it was a permission problem (root Vs user install) : I reinstalled all modules in ~/.raku (user) so I will be happy for 100 years (or maybe days). Take care of the RAKUDODIR hardcoded in Z

In my bashrc

export PATH=$HOME/.raku/share/perl6/site/bin/:$PATH    # zef and jupyter-kernel.raku
export PATH=$HOME/.raku/bin:$PATH

We should have done a Renaming day but someone has to start. So I support 200% your initiative @bduggan.

Update: Just update pygment : the alias has been done [month ago by Georg Brandl

Old post: (10 min ago is obsolete)

Time for me to go to pygment and ask for perl6 -> raku to get color.

Welcome to Raku (rakudo 2020.02.1.205.g.78371.bb.0.c).

[bduggan]

Thanks for looking into this @tinmarino. I was wondering about the error message. Currently with pip install pygments --upgrade I get pygments version 2.5.2, and with pip3 install pygments --upgrade I get 2.6.1 (or even pip3 install git+git://github.com/pygments/pygments --upgrade doesn't seem to help) -- have you had success installing a version that works?

[tinmarino]

It works here. Strangely my version is also 2.6.1 and pip3 install git+git://github.com/pygments/pygments --upgrade --force-install should have worked. Maybe add the --force-install because the first 2.6.1 release may be old.

Reinstalling jupyter with pip3 (instead of pip) fixed it :-)
