define a way to add interpreters

[sbragagnolo]

Now if I need a new interpreter but the scale basic one, i need to make a new image with the installation of the interpretation.

I should define a way to hook up interpreters from fuel files maybe, and define dynamically what's possible.

Can you give an example of what you want?

1st) Will the separate interpreter be already loaded or downloaded?
If it is loaded on demand, I would expect it would be cached somewhere.

2nd) Maybe we can change the interpreter just by changing the shebang:

#! /usr/local/bin/scale
=>
#! /usr/bin/env scale

or even better =>

#! /usr/bin/env pharo scale

=>

#! /usr/bin/env pharo scale --interpreter InterpreterClass

Dynamic magical variables that relies in code that may not be in the image. In the end is the import we were talking at the lab:

import file: 'myModule.st' into: #myMagicalVariable.

Or even also

import repository: 'github://whatever/project/bashFacade.st' into: #bash.
bash chmod: '+x' to: myFileRef.

The only thing we need to add is a nice way to define this kind-of-functions and persist this code in a more pharo way, so for developing this modules we can use pharo it self.

#! /usr/bin/env pharo scale --interpreter InterpreterClass

Beware, there are limitations on how many words after the shebang will be taken into account (depending on OS and shell versions, of course, because POSIX is a well-defined cough standard)
