- How do I create a usable, distributable image without distributing
the source. (My source is hopelessly distributed over hundreds of
files with allot of secrets ;-) )
I'd not. Remember the "Scripting" part of GNU Smalltalk. But if you
really want, create a class EchoMain, and add a method to get the
#returnFromSnapshot update from ObjectMemory:
Object subclass: #EchoMain
instanceVariableNames: ''
classVariableNames: ''
poolDictionaries: ''
category: 'Language-Implementation'!
!EchoMain class methodsFor: 'foo'!
update: aspect
aspect == #returnFromSnapshot ifTrue: [
Smalltalk arguments = #('--repl') ifFalse: [
self main: Smalltalk arguments.
ObjectMemory quit ] ]!
main: argv
"I love Java names!"
argv
do: [ :a| Transcript nextPutAll: a]
separatedBy: [ Transcript nextPutAll: ' '].
Transcript nl! !
ObjectMemory addDependent: EchoMain.
ObjectMemory snapshot: 'echo.im'!
Run this script and it will create an echo.im image. If you have gst in
your path, you can just do "chmod +x echo.im" and then "./echo.im abc def".
I've placed a small hook, in that "./echo.im --repl" will bring the
standard read-eval-print loop up.
- How could I make it replace my current echo binary (although not
currently possible, without the extra flags). In short: make it
'self-contained' or executable.
If you have an image, of course it's just "cp echo.im /bin/echo" (not
suggested :-). If you have a script, add "#! /usr/bin/env gst -f" at
the head of it, or this:
#! /bin/sh
"exec" "gst" "-f" "$0" "$@"
PS and Offtopic: is there a way to load another image and call an
object within that image? Effectively using other images as libraries?
No, though in principle what you are describing is an RPC server.
