Awesome and thanks! I'm trying to determine if I have a use case. Not sure if the fairly large CSV files I typically work with are too big as input vectors for APL.
- lokedhs 10y agoHow big are they. GNU APL isn't particularly tuned for this use case but arrays of a few hundred thousand rows is not a problem. I have had performance problems at several million rows, but it all depends on what you do.
- throwaway7645 10y agoUsually not in the millions, but occasionally they are. I've seen a few videos for Dyalog-APL & J, but nothing on GNU-APL. Even a blog post would be welcome on setup with emacs/vim...etc.
- lokedhs 10y agoSome time ago I created a video showing some of the features of the Emacs mode. I really should make a new one, since there have been some more development since then, and some features could have been shown better. Hopefully it can still be helpful: https://www.youtube.com/watch?v=yP4A5CKITnM https://www.youtube.com/watch?v=yP4A5CKITnM
- throwaway7645 10y agoThank you! I'll watch it in full tonight. I'm not sure if you mention it or not, but are you using a special APL keyboard? Curious how you enter the characters.
- lokedhs 10y agoThe Emacs mode provides two different methods to input APL symbols. It allows you to set a prefix key (like Super for example) that will map to the symbols, or you can use the APL imput method which uses "." (period) as a prefix when typing them. When using it, you can type C-c C-k which will open a quick help that shows they keymap.
