Counts how many times an old-string occurs in a supplied file text (as a replace-in-file tool would see it) and returns each match's offset, line, column and surrounding lines, for an agent about to issue an edit. pass:...

Given any three of aperture (f-number), shutter time in seconds, ISO and scene EV at ISO 100, solves the fourth from EV = log2(N^2/t) and EV_S = EV_100 + log2(S/100), names the nearest one-third-stop f-number, and lists...
Parses a chemical formula (parentheses, brackets, hydrate dots such as CuSO4·5H2O, an ignored charge) for a chemist or an agent that must check a molar mass, and returns the Hill-notation formula, the formula weight in g...
