System Commands.

[Montel Edwards-3]

Hello, I am new to Boo. Mostly new to programming in whole. I have looked all over for support but going here is all that I can find. So, I wanted to know how I would go about running system commands.

Kind of like the subprocess.call on python.

Thanks, 

Montel Edwards

Hi,
AFAIK, boo has very few specific libraries. For most things, it relies on the underlying .NET/Mono libraries. So you should study those, for which there is documentation at mono site (if you are on Linux/ OS X) or at Microsoft .NET sites if you are on Windows. They are both easily googable, so I will spare the links ...

(and no, I can't give you a direct answer because I am also new to .NET)

Ciao

Hi and welcome to Boo :)

You want to look at System.Diagnostics.Process : http://msdn.microsoft.com/en-us/library/system.diagnostics.process_members.aspx

Cheers,

For that particular case there's actually a buitin function:
shell(command as string, args as string). Ex:

   print shell("ls", "")

Oh, thanks. I did find something else earlier it was like
import System
Systen.Diagnostics.Process.Start("ls")

What is the difference?

shell is implemented on top of System.Diagnostics.Process. All it does
is to capture the process output and return it as a string.

Oops, indeed.
It almost screams for a gendarme rule to detect patterns which would better be boo-ified :-p

While this is all true, it is probably worth asking what it is you're trying to do through the shell? I can't guarantee it but the underlying framework is very robust and probably has a better way to do what you're wanting to do than through shell commands. For example if you're trying to do an "ls" you could use the System.IO.Directory class instead. This will save you a lot of string parsing. If you need to call some 3rd party application then you're probably stuck with the shell but anything having to do with the file system is probably a heck of a lot easier through the built-in classes.
