Installation
The library lxml is needed. Please reference
here for more information.
If you are an Debian/Ubuntu user, simply type:
$ sudo apt-get install python-lxml
Usage
Using Codeforces Problem 198A problem as an example.
Donwload Sample Tests
The url of this problem is http://codeforces.com/problemset/problem/198/A. Please notice the contest_id is 198 and the problem_id is A.
$ cf.py -c 198 -p A # download this problem
$ cf.py -c 198 # download all problems in this contest
There is another url http://codeforces.com/contest/198/problem/A which indicated the same problem. You can see the contest_id and problem_id is same, so it wouldn't be a problem.
Running the Tests
Suppose your source code is named A.{lang}, which {lang} could be
cpp, c, java or py for the current version.
Then, simple run cf.py A.{lang}, you will get the result like this:
$ cf.py A.java
output:
2
=== Case #1: AC (85 ms) ===
output:
2
answer:
3
=== Case #2: WA (83 ms) ===
press enter to continue or <C-c> to leave.
output:
Exception in thread "main" java.lang.Exception
at A.<init>(A.java:12)
at A.main(A.java:18)
answer:
0
=== Case #3: RE (95 ms) ===
press enter to continue or <C-c> to leave.
Configurations
The file `conf.py' contains the compile & execute commands of support languages, so you could add more commands to support more languages easily by yourself.
The section [global] in conf.py contains some setting about the test
file's name. Since the source code's name and the test file's name
must be exactly same, you could change these settings to follow your
naming convension. For example:
In the default setting:
PATTERN = "upper({id})"
REPLACE_SPACE = "_"
EXTENSION = ".xml"
the filename would be 'A.xml'
Or you could added the contest id and problem's name: (also notice the
replace_space)
PATTERN = "{contest}-upper({id})-lower({name})"
REPLACE_SPACE = "-"
EXTENSION = ".xml"
the filename would be 'A-about-bacteria.xml'
About
This tool is only verifiid on Linux now, but I think it could be run on other platforms, although it maybe need a little modify.
