Passing parameters to a Bash function
...am ${age} years old."
}
You can also annotate arguments as @required or @readonly, create ...rest arguments, create arrays from sequential arguments (using e.g. string[4]) and optionally list the arguments in multiple lines:
function example {

Extract substring using regexp in plain bash
...
Using pure bash :
$ cat file.txt
US/Central - 10:26 PM (CST)
$ while read a b time x; do [[ $b == - ]] && echo $time; done < file.txt
another solution with bash regex :
$ [[ "US/Central - 10:26 PM (CST)" =~ -[[:space:]]*([0-9]{2}:[0-9]{2}) ]] &&
echo ${BASH_REMATCH[1]...
How can I cast int to enum?
...var e2 = (MyEnum)6;
Console.WriteLine("{0} {1}", e1, e2);
Console.ReadLine();
}
Note that casting to e2 also works! From the compiler perspective above this makes sense: the value__ field is simply filled with either 5 or 6 and when Console.WriteLine calls ToString(), the name of e1 is re...
Iterate over the lines of a string
...ef f4(foo=foo):
stri = StringIO(foo)
while True:
nl = stri.readline()
if nl != '':
yield nl.strip('\n')
else:
raise StopIteration
Measuring gives:
$ python -mtimeit -s'import asp' 'list(asp.f4())'

How do you merge two Git repositories?
...history, blame some changes.
git log <rev>
git blame <rev> -- README.md
Note that you can't see the directory prefix from here since this is an actual old branch left intact.
You should treat this like a usual file move commit: you will need an extra jump when reaching it.

Proper way to wait for one function to finish before continuing?
...ne, in my experience they tend to result in code that is more difficult to read and maintain. There are situations where I still use them though, such as to pass in progress events and the like as parameters. This update is just to emphasise alternatives.
Also the original question doesn't specific...
Fastest way to determine if an integer's square root is an integer
...found looking at the last six didn't help.) I also answer yes for 0. (In reading the code below, note that my input is int64 x.)
if( x < 0 || (x&2) || ((x & 7) == 5) || ((x & 11) == 8) )
return false;
if( x == 0 )
return true;
Next, check if it's a square modulo 255 = 3 * ...

What kinds of patterns could I enforce on the code to make it easier to translate to another program
... modify in the context of another 80,000 lines of translated program you already don't understand. That takes a huge amount of effort. At the million line level, this is simply impossible in practice. (Amazingly there are people that distrust automated tools and insist on translating million line...
Is there a way to word-wrap long words in a div?
...
Reading the original comment, rutherford is looking for a cross-browser way to wrap unbroken text (inferred by his use of word-wrap for IE, designed to break unbroken strings).
