I have been under the impression that processes on the operating system have three standard streams: stdin, stdout, and stderr. I have also thought that text editors like vim work by taking input over stdin and sending ANSI escape characters over stdout. However, my view of how command-line interpreters isn't holding up in this one case:...
What is the best practice (interface and implementation) for a command line tool that processes selected files in a directory tree? I give an example that comes to my mind, but I am looking for a 'best practice': flipcase foo.txt foo2.txt could process foo.txt and save the result as foo2.txt. flipcase -rv *.txt could process all ...

I'm writing an interpreter. The interpreter accepts arguments that it itself uses, including a file to interpret.

You have wrapper python script that is calling another python script, currently using os.system('python another.py some-params'). You want to be able to debug both scripts and if you use os.system() you'll loose the debugger, so it does make sense to load the second script using the same interpretor instead of starting another one. imp...

We're using TeamCity's command line build runner to call a bat-file. The bat-file builds our solution by calling the Visual Studio 2008's "devenv.exe" and then it executes the unit tests and creates the correct folder structure. What we would like to do is to stop executing the bat-file if the call to devenv fails and make the TeamCity...

At the highest level I only wish to parse some options and leave the rest to "lower levels". however, all libraries I've tried so far (Common Cli, args4j, JOpt, gnu.jargs) al throw an "unknown option" exception when I'm trying to feed t...
