From time to time when discussing features in other languages and what Rust learn from them people (including me) post snippets using those languages… However, if we say something like:
```haskell
data Foo = Bar
struct Foo {
}
```
this will be highligted as if it was Rust code.
Example:
class Functor f where // Here is a Rust comment which is recognized as a comment.
fmap :: (a -> b) -> (f a -> f b)
-- Here is a Haskell comment which is not recognized as a comment.
So it would be nice to have the usual markdown capabilities here to highlight any language.
// a small Java program
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
new Object();
protected
}
}
#!/usr/bin/env python
import socket
import subprocess
import sys
from datetime import datetime
# Clear the screen
subprocess.call('clear', shell=True)
# Ask for input
remoteServer = raw_input("Enter a remote host to scan: ")
remoteServerIP = socket.gethostbyname(remoteServer)
# Print a nice banner with information on which host we are about to scan
print "-" * 60
print "Please wait, scanning remote host", remoteServerIP
print "-" * 60
# Check what time the scan started
t1 = datetime.now()
# Using the range function to specify ports (here it will scans all ports between 1 and 1024)
# We also put in some error handling for catching errors
try:
for port in range(1,1025):
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
result = sock.connect_ex((remoteServerIP, port))
if result == 0:
print "Port {}: Open".format(port)
sock.close()
except KeyboardInterrupt:
print "You pressed Ctrl+C"
sys.exit()
except socket.gaierror:
print 'Hostname could not be resolved. Exiting'
sys.exit()
except socket.error:
print "Couldn't connect to server"
sys.exit()
# Checking the time again
t2 = datetime.now()
# Calculates the difference of time, to see how long it took to run the script
total = t2 - t1
# Printing the information to screen
print 'Scanning Completed in: ', total
