I don't think it's quite what you're talking about, but I have an Emacs function that runs the current region through Python and replaces it with the stdout from running it. For your example, I write this: vars = list('abcdefghijklm') for v,i in zip(vars, range(len(vars))): print("#define {} {}".format(v, i)) Select it and press Ctrl+Alt+p and have it replaced by: #define a 0 #define b 1 #define c 2 #define d 3 #define e 4 #define f 5 #define g 6 #define h 7 #define i 8 #define j 9 #define k 10 #define l 11 #define m 12 https://gist.github.com/1355548 https://gist.github.com/1355548
