Kattis Problem Tools

master: . develop:

These are tools to manage problem packages using the Kattis problem package format.

Programs Provided

The problem tools provide the following three programs:

• verifyproblem: run a complete check on a problem
• problem2pdf: convert a problem statement to pdf
• problem2html: convert a problem statement to html

Running any of them with command-line option -h gives documentation on what arguments they accept.

Example Problems

A few examples of problem packages can be found in examples.

Installing and using problemtools

There are three recommended ways of installing and running problemtools.

Method 1: Install the Python package

Run

pip install git+https://github.com/kattis/problemtools

Or if you don't want a system-wide installation,

pip install --user git+https://github.com/kattis/problemtools

With this second option, in order to get the command line scripts, you need to make sure that the local user bin path used (e.g., on Linux, $HOME/.local/usr/local/bin) is in your $PATH.

In order for problemtools to run properly, you also need to have LaTeX and various LaTeX packages installed. See Requirements and compatbility below for details on which packages are needed.

Method 2: Run directly from the repository.

In order for the tools to work, you first have to compile the various support programs, which can be done by running make in the root directory of problemtools.

When this is done, you can run the three programs bin/verifyproblem.sh, bin/problem2pdf.sh, and bin/problem2html.sh directly from the repository.

See Requirements and compatibility below for what other software needs to be installed on your machine in order for problemtools to work correctly.

Method 3: Build and install the Debian package

This applies if you are running on Debian or a Debian derivative such as Ubuntu.

Run make builddeb in the root of the problemtools repository to build the package. It will be found as kattis-problemtools_X.Y.deb in the directory containing problemtools (i.e., one level up from the root of the repository).

To see which packages are required in order to be able to do this, see the "Build-Depends" line of the file debian/control.

The package can then be installed using (replace <version> as appropriate):

sudo gdebi kattis-problemtools_<version>.deb

This installs the three provided programs in your path and they should now be ready to use.

Requirements and compatibility

To run the tools, you need Python 2 with the YAML and PlasTeX libraries, and a LaTeX installation. In Ubuntu, the precise dependencies are as follows:

libboost-regex1.54.0, libc6 (>= 2.14), libgcc1 (>= 1:4.1.1), libgmp10, libgmpxx4ldbl, libstdc++6 (>= 4.4.0), python (>= 2.7), python (<< 2.8), python:any (>= 2.7.1-0ubuntu2), python-yaml, python-plastex, texlive-latex-recommended, texlive-fonts-recommended, texlive-latex-extra, texlive-lang-cyrillic, tidy, ghostscript

The problem tools have not been tested on other platforms. If you do test on another platform, we'd be happy to hear what worked and what did not work, so that we can write proper instructions (and try to figure out how to make the non-working stuff work).
