euler
is a command line tool for running and
submitting Project Euler problems. Go here to see what
it looks like when you submit a successful problem:

Get Started
I've submitted it to Macports, but in the meantime you need to do a little bit of work to get started. You need the jp2a, ImageMagick and BeautifulSoup libraries installed.
$ sudo port install jp2a ImageMagick py27beautifulsoup
Then grab the euler script (just one file) and place it somewhere in your
PATH
.
Usage
euler
requires two pieces of information from you: the number of the
problem you are trying to solve, and your proposed solution. You can do this in
one of a few ways:

Submit a problem number and a problem file.
euler
will run the problem file and treat the first line of output as the solution.$ euler p 22 problem22.py $ euler p 17 myjavasolution.java

Submit a problem number and a solution.
Use the
s
orsolution
flag.$ euler p 14 s 24289 $ euler problem 11 solution 242113

Pipe the solution to Project Euler.
Here you go, fancy pants:
$ perl problem240solution.pl  euler p 240
This assumes that your file will output the solution as the first argument to stdout.
Username Configuration
You can also save your username and password in a file named
.eulerrc
in your home directory (~/.eulerrc
or
/Users/yourusername/.eulerrc
). The format is:
[login] username = myusername password = mypassword
Note that there are no quotes around your username or password.
Supported Languages
Here are the languages currently supported by euler
:
C C++ Haskell Java Python Ruby
If your language isn't supported, you can pipe a solution in via stdin:
$ sml problem4.sml  euler p 4
Or specify your solution as another argument on the command line:
$ euler p 4 s 99032
Pull requests to add new languages are also welcome.
