  Modern IDEs don’t improve the feedback loop much unfortunately, more often it’s quite the opposite. They are slow, bloated and distracting. Some of them might be good at renaming one’s variables as part of their refactoring offer, but otherwise the situation is quite often bleak.

  SBSL+SLIME+Emacs usually put one in the flow state in no time. That’s what keeps amazing me and keeps me productive.

  And then, Claude seems to be quite alright discussing tricky Common-Lisp-related stuff.

    This is an experience that is 15 years out of date.

    • brabel – yesterday

      Hm I agree completely. Even as someone who appreciates SLIME and emacs. IntelliJ and even VS Code are excellent, even if heavy. Just use it on a beefy laptop and it won’t feel slow and bloated at all. If you find it distracting, it’s because you don’t know which settings to use to make them just right for your taste. Both can behave as Notepad if you want.

        even neovim with an lsp can be a very good experience, if one doesn't mind configuring it

        • maleldil – 21 hours ago

          Or Helix, if you want a TUI with modal editing, but you do mind configuring it.

      • packetlost – yesterday

        It's fine to not like them, but calling them slow is just not really true for "modern" IDEs, that's a big part of what makes them modern.

  For vim users, there's vim-slime:

  https://github.com/jpalardy/vim-slime

  I don't know if it's as powerful as the real thing, but it allows you to "send" your current vim line or paragraph to a tmux instance running a lisp interpreter, essentially. Very useful.

  • iroddis – yesterday

    +1 for vim slime. It’s not only amazing for programming in REPL languages. Since you can send anything from the buffer to another pane, it can be used to execute commands (send some rows from a cookbook to a remote shell), copy and paste segments of a local file to a remote source, and lots of other things. It’s a great example of doing something simple (send selections to another tmux/screen pane) that can be used in all kinds of useful ways. Very much the unix philosophy.

    I also found this blog post useful for using Vim with Common Lisp https://susam.net/lisp-in-vim.html

  • phplovesong – yesterday

    Vim slime is awesome. I use it for tinkering in languages with a repl like ocaml or javascript.

    The feedback loop is probably the best in class from anything i have ever used. No IDE comes even close.

• peterohler – 2 days ago

  I've been writing Lisp code off and one since the 80s. The standard for Common Lisp has to be sbcl but the REPL is pretty minimal. The available packages tend to be more limited than Go which I've been using a lot lately. I did find a way to have a more functional REPL and also have access to all the Go packages by writing SLIP (https://github.com/ohler55/slip). Yes I know this is a plug for SLIP and if that offends anyone I apologize. The reasons mentioned for developing it are valid though and I've managed to use Lisp for almost all the data mining and processing tasks.

• iroddis – yesterday

  For people that use Lisp extensively, do you find the chording requirements of parentheses (shift-9 or shift-0) annoying? It feels like very bad ergonomics, considering how frequently the characters are used.

  Do you use a keyboard with mappings to make it easier? Rely on the editor to insert them for you?

  • Jtsummers – yesterday

    It's pretty much the same number of bracket-type characters as other languages, and both () and {} require the use of the shift key. Only counting the parentheses and curly braces:

      (defun hello (name)
        (format t "Hello, ~A!" name)) ;; 6 parens, 6 shift keys
    
      def hello(name):
        print(f"Hello, {name}") # 4 parens, 2 curlies, 6 shift keys
    
      void hello(char* name) {
        printf("Hello, %s\n", name);
      } // 4 parens, 2 curlies, 6 shift keys
    

    No real difference for typing.

  • obezyian – 5 hours ago

    It is bad ergonomics only on modern keyboards. Back in the day, there were keyboards with "lower case parentheses"[1].

    Same case for vi - the : key was in a different place, and no Shift necessary[2].

    Nowadays, I use a bespoke layout (in software) that solves the above two problems, among others. My number row is inverted, so parentheses become lower case, and I put the colon key next to 0 and Enter next to P.

  • dingleberry – yesterday

    probably not worse ergonomic because i type '(' with left pinky and right ring finger and ')' with left pinky and right pinky whereas {} [] etc, i have to use the very same overworked right pinky to distinguish two keys next to each other.

    i always have problems with keys that have no obvious dedicated finger position like the middle vertical columns especially 6 and b and of course keys reachable on the right pinky, especially \ and =

  • joshmoody24 – yesterday

    My ring finger is always slightly sore due to typing ( so often. Not just in LISP but any programming language. I've been experimenting with mapping l; to () when the caps lock key is pressed. So far so good, but I haven't used it long enough to develop muscle memory.

  • tmtvl – yesterday

    I mean, double quotes and curly brackets also require using the Shift key, as do the at sign, number sign, dollar sign, and ampersand. The brackets are a small enough part of the code that it doesn't matter.

    And besides:

      print("Hello World");
    

    requires just as much chording as:

      (print "Hello World")

    • amenhotep – yesterday

      Mostly these days it just requires that you start to type "print" and then press tab when appropriate, though. I feel like I relatively rarely type brackets manually for function calls. Lisp syntax doesn't seem amenable to this particular affordance?

      • tmtvl – 18 hours ago

        Why not? Could just type 'print', TAB, and have it put brackets and spaces in the right positions and leave the cursor in place for the first argument.

    • iroddis – yesterday

      That’s true, but the travel distance of the braces or the double quotes from the home row is much less than the travel distance from the parentheses. Just using shift isn’t the problem, it’s how far parens are from the normal hand position.

      • tmtvl – 20 hours ago

        > That’s true, but the travel distance of the braces or the double quotes from the home row is much less than the travel distance from the parentheses.

        That... depends on your keyboard maybe? On Dvorak the curly brackets are harder to reach than the round brackets. The open round bracket is also hit with the ring finger instead of the little finger, which is weaker.

• dingleberry – yesterday

  i use slimv instead

  i think the powerful feature is not (only) merely sending code to repl

  but the suggestion for function's parameter as the function is updated to repl

  for example: (defun xyz (a &option b &rest c &key d) ) ;then send this with ,d (vim+slimv) to swank server

  the next time i type (xyz ... vim status bar conveniently states: (xyz a &optional b &rest c &key d)

  both happen whether i start typing (xyz in repl or in vim; that's it, the function parameters show up as suggestions in repl and in editor

• jonathanstrange – 2 days ago

  I've been waiting for ages for a Lisp that allows me to develop in one running system, creating minimized images with a tree shaker to distribute parts of the system for production when needed, and that never came (at least not with an affordable license, I don't know about the commercial Lisps). People recommend Smalltalk for this but that's not a Lisp. Eventually, I've switched to Go because if I have to write individual files in Emacs anyway, I can just as well use a more static language.

• alfiedotwtf – yesterday

  I’ve read a few scheme books over the years, and recently bought p.g’s book…

  Though because I’ve had nothing to actually apply it to, it just gets forgotten about - that was until I decided to go all in on Emacs again about a year ago. And fancy that - I’ve written so much lisp (Elisp) in the past few months that even diving into Emacs extensions is t daunting anymore for me.

  Want to get started? Force yourself to use it every day. Throw yourself in the deep end - start from a vanilla Emacs setup, and each time something bugs you, stop and figure it out (what’s the function, variable, face, etc that needs changing, or do you have to write a few function to get what you want done) - it’s a friggen superpower!!!

• zombot – yesterday

  Way too heavy. Just install sbcl & vim.

• bitwize – 2 days ago

  Mark: So how do I get started in Common Lisp?

  Nolan: That's the neat thing—you don't.

  One of the interesting and, depending on your perspective, perhaps unfortunate side effects of LLM-assisted development becoming the standard is that LLMs almost completely disincentivize choosing an unpopular language for serious work. Due to the much higher volume of training data, you're better off using TypeScript, Go, or Rust (or Swift if you're in Apple-land or Kotlin if you're in Android dev hell). Those languages with an LLM will make you far more productive than even an "expressive" language like Lisp.

  Plus there are complete, modern IDEs for those that let you get started right from the jump, rather than having to build your own IDE out of Emacs and assorted parts before you can actually develop your application.

    I'm currently working on a game (SBCL & OpenGL) and Claude had no problems helping me with rendering pipeline issues in SBCL.

  • MycroftJones – 2 days ago

    Claude has been doing a pretty good job at writing newlisp code, reasonably idiomatic too. newlisp is a niche language.

  • cianuro_ – yesterday

    I use Elixir every day with Claude Code and I haven’t had any issue regarding syntax, ecosystem and BEAM specific knowledge yet.

    If anything I perceive a bit more mistakes when I have to do things in TS (and in a way simpler domain, in a way smaller project).

  • kazinator – yesterday

    GPT-4 in 2023 was able to write code in a rare Lisp dialect. Also SNOBOL4 and other things.

  • pjmlp – 2 days ago

    The right way to start is with LispWorks or Allegro Common Lisp, exactly the surviving Common Lisp IDEs, instead of building your own IDE out of Emacs and SLIME.

    However I do agree with the AI part.

  • tosh – 2 days ago

    And yet: current state of the art models are also great at navigating and trying language ecosystems that aren't as mainstream. So if you're curious it's now great to explore topics, languages, concepts that — even if not mainstream — were so far a bit out of reach.
