Sending a message to pharo from commandline

What happened to the pharo commandline "eval" function?

Does anyone know what happened to the pharo "eval" function on the
comnandline? It seems to have disappeared in the newer versions. The
Coral thing also seems to be abandoned as the readme is no longer there:
http://smalltalkhub.com/#!/~PharoExtras/Coral

Is there any way to send messages to pharo from commandline? Sometimes I
write an object in pharo and it can be useful to use if I am runing a
linux shell. Sometimes I have a bash script or something that needs an
answer from pharo.

Hi Steve,

What do you mean, AFAICT it is still there and works as before. Here is a terminal transcript on macOS:

prometheus:2018-12-20 sven$ ./pharo Pharo.image printVersion
[version] 'Pharo7.0.0' 'Pharo-7.0.0+rc1.build.66.sha.0ff3a6c1c0f1d9b2876c50e19b790dd7bb926dd9 (64 Bit)'

prometheus:2018-12-20 sven$ ./pharo Pharo.image --list
Currently installed Command Line Handlers:
    loadHermes            Loads the hermes files passed as parameter
    printVersion          Print image version
    save                  Rename the image and changes file
    initializePackages    Initialize packages and protocols from a given lists
    st                    Loads and executes .st source files
    config                Install and inspect Metacello Configurations from the command line
    metacello             Install and inspect Metacello Baselines/Configurations from the command line
    test                  A command line test runner
    Fuel                  Loads fuel files
    clean                 Run image cleanup
    get                   Install catalog projects from the command line (consult catalog at http://catalog.pharo.org)
    perform               Perform given message on a specified class or global
    eval                  Directly evaluates passed in one line scripts

prometheus:2018-12-20 sven$ ./pharo Pharo.image eval --help
Usage: eval [--help] [--save] [ --no-quit ] <smalltalk expression>
        --help                   list this help message
        --save                   save the image after evaluation of the expression
        --no-quit                if specified, the image continues runing after
                                 evaluating the <smalltalk expression>
        <smallltalk expression>  a valid Smalltalk expression which is evaluated and
                                 the result is printed on stdout

Documentation:
A CommandLineHandler that reads a string from the command line, outputs the evaluated result and quits the image.

This handler either evaluates the arguments passed to the image:
        pharo Pharo.image eval  1 + 2
       
or it can read directly from stdin:

        echo "1+2" | $PHARO_VM my.image eval

Important: don't manually save the image at the end of the expression by calling something like 'Smalltalk snapshot: true andSave: true'! Instead, use the safer --save option.

prometheus:2018-12-20 sven$ ./pharo Pharo.image eval '42 factorial'
