Batch-render LaTeX equations to cropped, transparent PNG and SVG.
Bash LaTeX
Slides need equations as images, and producing them one screenshot at a time is miserable. This walks a formulas/ directory, compiles each .tex file with pdflatex using the standalone class, and emits both a 300 dpi transparent PNG and an SVG next to the source.
Several formulas can live in one file, separated by %%%, each with an optional label that becomes its filename. Change a formula, re-run, and every derived image is current again.
