If you’re really trying, you will always be able to write completely unreadable code in any programming language. All the language designers attemts to force you to write readable code, and even making it so the easiest way ahead, even for quick hacks is to write it as readable and reusable code will fail if you’re really trying to write unreadable code.

This guy is obviously concerned about “job security”. (not the blog author, but the code author)

Aaannd… Heres my understanding of the code:

?View Code PYTHON
#!/usr/bin/env python
import os,sys
 
#bail out if there's no sandbox specified
assert len(sys.argv)==2,"you must provide a sandbox name"
sandbox=sys.argv[1]
 
#get the dir of this script
home=os.path.abspath(os.path.dirname(__file__))
 
#sandboxdir is this dir/sandboxname
sandboxdir=os.path.join(os.path.dirname(home),sandox)
 
#go into the root of the sandbox
os.chdir(sandboxdir)
PST=os.path.join(sandboxdir,'bin','paster')
VAR=os.path.join(sandboxdir,'var')
ETC=os.path.join(sandboxdir,'etc')
 
#make var directory if it doesnt exists
if not os.path.exists(VAR):
    os.mkdir(VAR)
 
print "restarting "+sandbox
 
# Build the system commands required to restart the sandbox
cmds=[]
cmds.append('source %s' % os.path.join(sandboxdir,'bin','activate'))
cmds.append(PST+" serve --daemon --pid-file=%s/sandbox.pid"
            "--log-file=%s/sandbox.log %s/sandbox.ini start" % (VAR,VAR,ETC))
CMD=";".join(cmds)
PRNT(CMD)
 
#run the cmds
if os.system(CMD) == 0:
    print "All done!"
    sys.exit(0)
else:
    print "Ooops. failed."
    sys.exit(1)
