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

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 without any command-line options gives documentation on what parameters they accept.

There are two recommended ways of installing and running problemtools.

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 X.Y as appropriate):

sudo gdebi kattis-problemtools_X.Y.deb

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

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.

The checktestdata program requires a relatively recent gcc version (4.8 suffices), but is only needed for running checktestdata input validation scripts. The rest of problemtools will run fine without it, but in this case you need to build the other programs separately, e.g. by running

(cd support/default_validator && make)
(cd support/interactive && make)

When this is done, you can run the three programs verifyproblem.py, problem2pdf.py, and problem2html.py directly from the src directory of problemtools.

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).
