Page Break Control Implementation Summary

Changes Implemented

1. Core Configuration Files Modified

/HSRTReport/Config/Typography.tex

  • Added enhanced page break control penalties
  • Implemented listing and itemize environment protection
  • Added needspace package for conditional page breaks
  • Configured float placement control
  • Set up protected itemize/enumerate environments
  • Defined listenabsatz environment for compact lists

/HSRTReport/Config/PageBreakControl.tex (New File)

  • Created comprehensive page break control module
  • Implemented section-level space requirements (12/10/8 baseline skips)
  • Added protected environments for lists and listings
  • Created smart section commands
  • Implemented conditional page break commands
  • Added figure/table protection

/HSRTReport/HSRTReport.cls

  • Added inclusion of PageBreakControl.tex module

/HSRTReport/Modules/Content/Listings.tex

  • Updated listings configuration to prevent page breaks
  • Added float=H option to keep listings in place
  • Modified blstlisting environment for better page break control

2. Key Features Implemented

Section and Paragraph Control

  • Minimum content after sections: Sections require ~2 paragraphs (12 baseline skips) or move to next page
  • Smart section breaking: Sections check available space before placement
  • Paragraph cohesion: Enhanced penalties to keep paragraphs together

Listing Protection

  • Listings automatically stay on the same page when they fit
  • float=H option prevents floating
  • Protected listing environment available for guaranteed no-break

List Environment Protection

  • Itemize and enumerate lists stay with preceding paragraphs
  • Automatic penalties added to standard environments
  • Protected versions available: nobreakitemize and nobreakenumerate

3. Technical Implementation Details

Penalties Applied

  • \widowpenalty=10000 - Prevents orphaned lines
  • \clubpenalty=10000 - Prevents widowed lines
  • \interlinepenalty=150-5000 - Variable penalty for list items
  • \floatingpenalty=20000 - Strongly discourages float breaks
  • \predisplaypenalty=10000 - Prevents breaks before equations
  • \postdisplaypenalty=10000 - Prevents breaks after equations

Package Dependencies

  • needspace - For conditional page breaks based on available space
  • afterpage - For deferred page break commands
  • placeins - For float barriers at section boundaries
  • enumitem - For customized list environments (already included)
  • etoolbox - For environment hooks (already included)

4. Usage Examples

Automatic Protection (Works Without Changes)

\section{Title}
This content automatically requires sufficient space or moves to next page.

\begin{itemize}
    \item Lists are automatically protected
    \item From breaking with their introduction
\end{itemize}

\begin{lstlisting}
Code listings stay together automatically
\end{lstlisting}

Manual Control When Needed

% Force content to stay together
\begin{critical}
    Important content that must not split
\end{critical}

% Protected list
\begin{nobreakitemize}
    \item Guaranteed to stay together
    \item No page breaks within
\end{nobreakitemize}

% Smart section with space check
\smartsection{Intelligent Section}

% Conditional page break
\conditionalpagebreak[15\baselineskip]

5. Configuration Values

Element Minimum Space Required Description
Section 12 baseline skips ~2 paragraphs
Subsection 10 baseline skips ~1.5 paragraphs
Subsubsection 8 baseline skips ~1 paragraph
Listing 5 baseline skips ~5 lines minimum
Float pages 80% full Minimum fill for float-only pages
Text on float pages 10% minimum Ensures some text with floats

6. Benefits

  1. Improved Readability: Sections don't start with minimal content at page bottom
  2. Better Structure: Related content stays together (lists with introductions, code samples)
  3. Professional Appearance: Eliminates awkward page breaks
  4. Flexibility: Automatic behavior with manual override options
  5. Compatibility: Works with existing HSRT Report template structure

7. Testing Results

  • Document compiles successfully with make compile
  • PDF output generated without errors
  • Page break penalties active and functioning
  • No conflicts with existing template features

8. Files Created/Modified

New Files:

  • /HSRTReport/Config/PageBreakControl.tex
  • /PageBreakControl_Usage.md
  • /PageBreak_Implementation_Summary.md

Modified Files:

  • /HSRTReport/Config/Typography.tex
  • /HSRTReport/HSRTReport.cls
  • /HSRTReport/Modules/Content/Listings.tex

9. Maintenance Notes

  • All changes are modular and contained within configuration files
  • Can be disabled by removing PageBreakControl.tex inclusion
  • Individual features can be adjusted through penalty values
  • Compatible with future template updates

10. Known Limitations

  • Very long sections may still need manual intervention
  • Float placement may occasionally override page break preferences
  • Performance impact minimal but present for very large documents
