Purpose

loop D il R ~cross

phl Ul < @Eu "$I$" phl Ur > @Eu "$A$" cl R;~ phl Ul < @Eu "$J$" phl Ur > @Eu "$B$"

phl Ul > @E "$e^-$" phl Dl < @E "$e^-$" (move |r;uput {7pt}[d] | $\gamma$) pl R;~ phl Ur < @E "$e^+$" phl Dr > @E "$e^+$"

Downloads

• documentation with further examples
• source code

Installation

• prerequisites:
  • recent C++ compiler (e.g. g++ >=8.x.x, Apple CLANG >=10)
  • flex and bison
  • make and cmake
  • a LaTeX installation providing packages amssymb, pstricks, pst-node, pst-coil, color, graphicx, pstricks-add, bm, vmargin (on debian based installations this is included by texlive-latex-extra)
  • ps2pdf and pdfcrop (for generation of PDF files)
  • pdftocairo (for the generation of SVG files)
  
  
• Compilation from source: tar -xf Diag2PS-1.0.tar.xz && cd Diag2PS-1.0/BUILD && cmake ../cmake && make Creates executable Diag2PS in BUILD directory.
  If you get error messages like
  "fatal error: optional: No such file or directory"
  your C++ compiler is not recent. Please see prerequisites.
  
  
• test:
  • creating LaTeX (PSTricks) input ./Diag2PS <test.diag (reads from stdin, writes to stdout)
    
    
  • creating PDF and SVG output ./Diag2PS -pdf -svg test.diag You will notice that this command takes slightly longer. This is mostly due to the bounding box calculations.
