    Reminds me very vaguely of Thomas Dickey’s add program, which is a running-total calculator like you’d see with the old desktop calculators with a paper roll, only with recalculation if you change earlier rows, etc.

    As an interesting side note, add and some associated programs are why ncurses supports default background colors.

      Thomas Dickey seems to be a really interesting person, who’s been a part of a lot of common software, and yet outside of his website I very rarely hear about him. This seems quite ironic given he’s got a page dedicated to the fact that he’s chosen not to be anonymous in order to gain a reputation, but he’s certainly made me curious about him.

        I don’t read the page as a bid for recognition, more a discussion that the idea of anonymity has a number of drawbacks.

        I have not heard of Dickey either, but I have heard of lynx,vile, and ncurses.

      Looks great. Much like M-x calc itself, it looks like one of those really powerful Emacs things that I’d love to take for a spin, but I really can’t think of any use cases. Curious to hear from the author what itch this scratches.

        The original inspiration came from Tydlig, which does similar things, but can’t save. I wanted something simple that could do live-updating calulations with intermediate values, and that also saves to a file. The result is this. If you don’t need tables/graphs, this is an okay spreadsheet alternative that is also plaintext.

        I’m planning to add better export (/import?) in the future to make it easier to just dump out results once you’re done calculating, at which point you literally just have a text file with all the data you need.

          What I love about calc is that you both have an RPN calculator and a “paper trail” like in old physical calculators with paper rolls.

          I also believe it’s arbitrary precision… I just randomly calculated 24^24 and got 1333735776850284124449081472843776 really fast on a cheap VPS…

            Can you not think of any use-cases for calc or this package?
