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'
