Ecosystem toasting is Serious Business™. You're LITERALLY running arbitrary code from hundreds of strangers!

It's HIGHLY UNrecommended to run this software on anything but a throw-away install that contains no sensitive data. Are you OK if ALL the files on the system published somewhere publicly but without you being able to ever get them again? If not, don't run this software!

Rakudo Prereq

You need Rakudo v2017.05.380.* or newer to run this software.

Blank Debian GCE VM Setup

On an out-of-the-box Debian, run these commands to prepare the system for toasting:

    sudo apt-get update
    sudo apt-get -y upgrade
    sudo apt-get -y install build-essential git curl aptitude libssl-dev \
        wget htop zip sqlite3 time \

        # libs needed by modules
        uuid-dev \ #LibUUID

    \curl -L | bash
    git clone ~/.rakudobrew
    echo 'source ~/perl5/perlbrew/etc/bashrc' >> ~/.bashrc
    echo 'export PATH=~/bin:~/.rakudobrew/bin:~/.rakudobrew/moar-nom/install/share/perl6/site/bin:$PATH' >> ~/.bashrc
    echo 'source ~/.bash_aliases' >> ~/.bashrc
    source ~/.bashrc
    perlbrew install perl-5.26.0 --notest -Duseshrplib -Dusemultiplicity
    perlbrew switch perl-5.26.0
    perlbrew install-cpanm
    rakudobrew build moar
    rakudobrew build zef

    # This one is to ensure git doesn't freeze up, waiting for a pass on some
    # dists that have wrong URL for source. The script gives it bogus pass
    # to use, so it just fails authen and moves on
    echo -e '#!/usr/bin/env perl6\nsay 42' > ~/bin/fake-ask-pass
    chmod +x ~/bin/fake-ask-pass
    echo 'export GIT_ASKPASS=~/bin/fake-ask-pass' >> ~/.bashrc

    mkdir .cpanreporter
    echo '' > ~/.cpanreporter/config.ini

    git clone toaster
    cd toaster
    zef --serial --/test --depsonly install .

    screen -L -S toast /usr/bin/time perl6 bin/toaster-perl6 2017.07 nom


To toast the ecosystem, run the bin/toaster-perl6 command, giving it as positionals args the tags, branches or commits (basically anything git checkout will accept). The toaster will build rakudos for the requested commits so ensure you've got space for that + anything the modules need, for each of the commits you're toasting.

Note: toasting takes ages (~50 minutes on a 24-core box), so don't go wild with toasting all the commits, if you're not prepared to wait for it.

The toaster will create an SQLite database in toast.sqlite.db file, with toasting results for each of the toasted module, and each of the given commits.

Perl Mojolicious

The Molicious-based viewer is currently the most up-to-date and recommended. To use it, install Perl, unless you already have it:

\curl -L | bash
echo 'source ~/perl5/perlbrew/etc/bashrc' >> ~/.bashrc
source ~/.bashrc
perlbrew install perl-5.26.0 --notest -Duseshrplib -Dusemultiplicity
perlbrew switch perl-5.26.0
perlbrew install-cpanm

Then install necessary Perl modules:

    cpanm -vn Mojolicious::Lite Mojo::SQLite List::Util

Then run the development version of the viewer if you want extra debugging output:


Or just run the production version of the viewer:


Then go to http://localhost:3333 to view the site.


To use rakudo for running the viewer, run bin/toaster-viewer and then go to http://localhost:3333 to view the site.

You'll need Tardigrade Web framework to run it:

zef --/test install

Note that currently this method appears to leak memory in one of the supporting modules.


Alternatively, just use SQL queries to view the results. They're all in the generated toast.sqlite.db file.

sqlite3 toast.sqlite.db
