Convert UCPC-flavored olymp.sty based TeX problem statements to HTML, complying with BOJ Stack and UCPC formatting guidelines.

For contests on BOJ with printed problemset, it is often challenging to:

• Keep TeX and HTML descriptions synced - especially when multiple problemsetters are working on multiple problems
• Convert one format to another - although BOJ supports MathJax, it is such a tedious and easily mistakable job to translate TeX markups to HTML. Few examples include:
  • \alpha → α (greek letter 'alpha')
  • `` ... '' → “ ... ” (double quotes)
  • \textit{...} → <em>...</em> (italic text)
  • \textbf{...} → <strong>...</strong> (bold text)
  • \begin{center}...\end{center} → <p style="text-align:center;"><code>...</code></span> (centered text)
  • \t{...} → <span style="color:#e74c3c;"><code>...</code></span> (colored verbatim)
  • \begin{itemize} \item ... \end{itemize} → <ul> <li>...</li> </ul> (unordered list)

This project aims to eliminate manual converting work by problemsetters, and make problemsetters to just focus on setting great problems.

1. Copy-paste olymp.sty based TeX problem statement into the left input area.
2. Preview the render output and fix the statement if needed.
3. Copy-paste generated HTML to BOJ Stack.

This tool offers the ability to try rendering the equations in pure HTML while avoiding MathJax as much as possible. Currently supports the following:

• Superscripts and subscripts
• Most of the TeX math symbol rendering commands, i. e. \le, \delta, \rightarrow
• Italic texts on variables
• Spacing around operators and functions like ln or sin
• Fractions
• \sum

Contributions are welcome!

• Cleanup code
• tabular environment
• Converting \color names to hex string
