I've spent a few hours playing with Alien+FFI and I did want to have a Command line interface to play and use as a quick browser.
Gofer it squeaksource: 'CLInterface'; package: 'ConfigurationOfCLInterface'; load.
ConfigurationOfCLInterface load.
To play with it write a script, for example startCLI.st, with the following:
CLInterface start
And then, from the command line
CogVM -vm-display-null <image> startCLI.st
What it does support? - executes smalltalk expressions - handles the errors and shows them into the stdout (so it does not explode :P) - stores variables as a workspace Since I used standard C functions (fgets and printf only) this should work on every platform from scratch (having a VM with FFI working, of course)...
The problems I've ran so far: - blocking FFI blocks the vm. I've not tried yet to use threads through FFI (and I don't know if it works. Does it?). But It should be great to start a headless seaside server with a command line :/.
Ok, it's a very simple thing, but it allows to execute a expression from a remote server via ssh without doing much :).

Cool, but why do you need to access those C functions ? You do know that you can access std* from Smalltalk, do you ? Have a look at the FileStream class 'stdio' category. Apart from that, nice small, readable and useful hack. Regards, Sven
