How do you learn vim-slime? I have used vim before, so I have basic skills there, but I get lost and run out of time when I try to figure out how the slime model works and how to create a lisp project. Is there a tutorial you followed or a video you found useful? What was your starting fund of knowledge?

Great question - it's shocking easy to learn. Just three steps 1. Install (via vim-plug, lazy.nvim, or whatever vim plugin manager you're using), 2. configure it. Depending on your terminal the instructions are a little different, but it should only take a few moments due to the brilliant instructions found here: https://github.com/jpalardy/vim-slime/tree/main?tab=readme-ov-file#targets https://github.com/jpalardy/vim-slime/tree/main?tab=readme-o... I use kitty so I add two lines to kitty.conf and it's all ready to go. But it will depend on your terminal/terminal emulator. The instructions in the readme should have you covered. Then 3. use it. This is shockingly easy, open two panes in your terminal with neovim on one side and REPL/interpreter on the other. For example I have neovim with my ruby file on the left pane and a rails console on the right (but on the right could be SBCL, python interpreter, or any other interpreter). In neovim, move the cursor to the line you want to run and press ctrl + c twice in quick succession. It will 'send' that line to the interpreter on the right pane and run that line! Note: The first time you do this you may be asked which pane vim-slime should 'send' the code to, with the numbers displayed over the panes. For example in kitty I'm usually sending to pane 2, so I press: 2 enter enter. If it was pane 5, I'd press 5 enter enter etc. If the line of code is immediately proceeded by another line(s) it will run that/those as well (for example, a multi-line Active Record query). It will do the same if there's one or more lines immediately above the current line. This takes a tiny bit of getting used to as you may unintentionally run lines immediately above/below the line for a short while. That's all there is to it! A few tips - As explained above, ctrl + c ctrl + c will run the line under the cursor. But you can also select and run any code you want by selecting it with vim's visual mode and ctrl + c ctrl + c to run that selected code. For example, if you want to run part of a line, select it in visual mode and ctrl + c ctrl + c and it will run! Same for say a few hundred lines of code: select it all in visual mode (e.g. v ctrl + f ctrl + f then j or k to get to the exact line), then ctrl + c ctrl + c will run everything you selected. - Rails specific: The rails console has a pager set to 'on' by default (this would necessitate back and forth between panes in order to press 'q' to quit out of the pager). So I turn it off by adding one line (IRB.conf[:USE_PAGER] = false) to ~/.vimrc or just .vimrc in the project directory. Let me know if you have any questions/troubles.
