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. - Steve |

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' 1405006117752879898543142606244511569936384000000000 HTH, Sven |

Hi Steve, Have a look at Clap: Coral was a nice idea but tried to be too many things at once (scripting syntax ≠ commandline API); in contrast, Clap is only about defining commandline APIs for Pharo code. Feel free to send questions & feedback my way, too :-) On Tue, 25 Dec 2018 at 19:46, Steve Quezadas <[hidden email]> wrote: What happened to the pharo commandline "eval" function? |
