What I think you want is a package called OSProcess. This is available
from within Squeak: open the Package Universe browser and you'll find
it under the "System" category. Then see OSProcess class>>helloWorld
and other examples.

Also check out the CommandShell package.

This is a telnet server in Squeak called "REPLServer" (under the
"Network" category) which implements a Smalltalk-like command line
with history, editing and a few other features. You could re-use much
of the code there if you want. I think that every operating system has
a telnet client, so you get a free command line for any platform.

I haven't seen any ncurses-like functionality in Squeak before. In my
opinion, that type of environment has been long obsolete and you
should just use a modern GUI.

FYI, you can load the latest versions of OSProcess/CommandShell from
SqueakSource. It's generally best to use the latest version, as I
don't keep the universes postings up to date as much as I should do.

To run Squeak as a /bin/sh replacement, see class ExternalCommandShell
in the CommandShell package, which is described here:

Thanks for all!

First of all apologies for my low level of English.
I Found a way to execute smalltak code from a squeak image
from unix bash that was what he needed, Of the next form:

1. evaluate "ExternCommandShell start" from squeak image.
2. Close squeak image
3. run from unix shell(bash): squeak -headless myImage
4. This open a sqsh interpreter.
4. Now run by example: Array with: 'Helo'

it possible execute a squeak smalltalk expression of the next way?

bash$  squeak -headless myImage  Array with: 'Helo'

my idea is execute a smalltalk espression directly desde bash.

Thanks.

I think CommandShell is neat, and have it loaded in my dev image.  It
provides nice interface to the Linux environment from within the
image.

Dave, would you mind if, in some future release of CommandShell, the
category for the test cases could be renamed so as to not cause a
dirty package in the trunk image?

Cheers,

This has been discussed before. If you search this mailing list,
you'll find a discussion.

"OSProcess arguments" will return the arguments passed on the command line.

Then you'll also want to know about:

SystemDictionary>>addToStartUpList:   " lets you run code when the
image starts. "
(Smalltalk is the only instance of SystemDictionary)

SmalltalkImage>>snapshot:andQuit:embedded: " To shut the image down
and return to bash. "

"Compiler evaluate:" will compile and run code.

Or... I think that GNU Smalltalk supports this kind of thing much better.

Chris,

Absolutely yes, and I need to fix OSProcess packaging similarly. And
I should also repackage them so the MVC and Morphic portions are
separated, so the Pharo folks don't get errors trying to load
all the MVC stuff.

On my to-do list :-/

Thanks for the reminder,

Dave

Instead of putting the Smalltalk expression on the command line,
you can send it to stdin like this:

  bash$ echo "Array with: 'Helo' ! ; exit" | squeak -headless myImage

The $! after the Smalltalk expression means interpret the expression
as a Smalltalk doIt instead of as Unix command.

ExternalCommandShell will evaluate "Array with: 'Helo' !" as a
Smalltalk expression and print the result on console. Then it
evaluates "exit" as a command, and the Squeak image will exit.

Dave

p.s. Your English is good enough!
