Lisp in 100 Seconds

[@SirKurt25]

4 years ago, I was responsible for maintaining a giant project from 1978, written in Lisp. There was a widely used syntax in that project and I didn't know what it did or how it worked. I searched the internet but nobody knew what it did. I just stopped meddling with it and ignored it for a while. Only later I discovered that syntax was possible thanks to a custom macro written in the project itself. The boomers created a domain specific language and didn't document it.

[@madsteeez]

I've had a similar experience

[@supremeleader5516]

What was the project

[@proosee]

well... Lisp is directly for this purpose: to create domain specific languages, so there should be no surprise there. Documentation is different matter, but sometimes code is your best documentation because it is by definition always up to date, of course it is only useful if it's written expressively enough.

[@gagagero]

​@@prooseeThe "purpose" of Lisp isn't to create DSLs lol. Macros should only be used where absolutely necessary. Wherever you can, you should use functions.

[@John-zq8nf]

So you entered new project and didn't even begin with learning language it uses? Well.

[@zaynelumpkin]

Learning to program a little Lisp (specifically, Racket) was one of the most rewarding things I ever did as a programmer. The syntax and the approach was so different from anything else I'd ever used, but Lisp was so internally consistent, and everything worked together perfectly once you figured it out; Everything is a list, every element of a list can be a list, and everything can be done recursively. It feels like a language from another planet, and getting familiar with it really expanded my mind and my approach to problems in programming. Learning some Lisp is an incredible way to challenge your assumptions and expand your ability to think about problems.

[@neilbedwell7763]

I'm with you. Personally, since LISP is so translatable, I posit that it really should be considered the definitive way to arrange computation, and that humanity has made a massive mistake making the lineage of LISP the exception. (it truly is in the direction of us having a language that can express any other language-implememtation solution and become a mid-point between comparing any other two languages, which essentially become DSL's with bizarrely chaotic implementations)

[@cristianocolangelo9920]

My university teaches Racket as first programming language (bachelor in computer science). Pretty hardcore

[@santhosh3374]

Its pretty similar to prolog.

[@taylankammer]

Some corrections and clarifications: 1. Scheme (1975) is older than Common Lisp (1984). Both are derived from but significantly different from John McCarthy's original LISP (1958) which is not used anymore. 2. The various "Lisp" languages are actually as different as C, C++ and C# so I would discourage from speaking as if "Lisp" is one programming language, unless you mean the original LISP. 3. Usually people say "LISP 1.5" when they mean the original one from McCarthy, because that's the last version of the original language that he published. 4. Some of the important innovations were first invented in Scheme, not LISP. That includes lexical scoping, true first-class functions/closures, and "hygienic" macros. 5. Scheme and Common Lisp are standardized, like C, and there are many implementations of them. CLisp is just one Common Lisp implementation, like GCC for C. 6. Scheme was originally a research project, and while newer and more feature-rich standards were published over the years, the standards continue to be very minimal. So you'll usually commit to a specific implementation, like Racket or Guile, if you want to do something serious with it. 7. Both Common Lisp, and serious/modern implementations of Scheme, can be and are used for "real" serious software projects. For example GNU Guix is a complete GNU/Linux distribution with many core components implemented with the Guile implementation of Scheme. 8. Both Common Lisp and Scheme can be compiled rather than interpreted, it's up to the implementation. The Chicken Scheme compiler actually converts Scheme to C before compiling it with a C compiler for instance. 9. Any talk about the Lisp family of languages is incomplete without mentioning Emacs Lisp. ;-) Emacs is essentially an implementation of a custom LISP-derived programming language called Emacs Lisp (most similar to Common Lisp from the bunch) that is special-tailored to the task of implementing a text editor in it.

@@gareth2021 My first impression was "weirdly simple", just put every command in parentheses and the operator/command/function in front, and evaluate from left to right inside parentheses. Otherwise its all the same stuff as other languages, but some of the names might be old. Translating a simple python program into a lisp-dialect, and then with a parser i use myself: def do_something (a, b): c = [a, b] for item in c: print(a, b, item) == (defun do_something (a b) (setq c (list a b)) (foreach item c (print a b item) ) ) == defun do_something (a b): setq c [a b] foreach item c: print a b item The real kicker though is that when it is tedious to write something that really shouldn't be a function or you need to write multiple necessary things for some simple input, you can make another command (a macro) out of that, and the compiler will add all the necessary things for you. Most beginners don't need to use this feature though, its a complete language as it is.

Definitely need this for literally every language that has at least some popularity. Another one, and this one isn't popular anymore, but still offers insight what today's systems *ought* to offer, is: Smalltalk !

In addition common lisp also has the common lisp condition system which allows you to do some really powerful stuff with exceptions allowing you to recover from errors in the repl.

[@EvanEdwards]

I was a little wary when I hit this video, but it is a solid introduction to a language with an extremely complex history and lauded for elegance that isn't always obvious, plus the weight of being such an early language the syntax is quirky by today's standards. Lisp is one of those "you should know these concepts down to the core if you want to make a career out of coding" languages. It's like learning to cook eggs perfectly when you want to be a chef: you learn a fundamental ingredient (protein) inside and out, plus you learn the rigor and mindset of _how_ to learn something inside and out. You'll see that ingredient used a thousand ways in a dozen forms, as a major and minor part, but you also can approach anything new with a wider approach of thought and learning. Seldom will you use Lisp directly, but you'll use variants and languages with features pulled from it over and over.

[@maccsguitar]

imo lisp makes the basics really easy: when you do maths, the thing you want to calculate first is out in parentheses. in lisp, every command is inside parentheses and everything in parentheses is evaluated from left to right before the command is run. when a command (a function) is run, it means that that command's parentheses and their contents can be replaced by the return value which is the value you get by evaluating the command's definition with the values after the command's name. that is done by evaluating those parentheses in order the same way as before. No language gets cleaner than that teaching the basics. I tried to start from c, quit, was forced to start with lisp, and after that everything in c-style language-syntax was so much easier to understand

Any love for Powershell? It's a JIT scripting language that runs on top of the .NET CLR. It uses a unique Verb-Noun naming scheme for functions, and if you make a function with an unapproved verb, it might throw a warning. Variables begin with dollar signs, like in PHP, and being a scripting language you don't need to declare them. Nor do you need to import modules, unless you're digging very deep into .NET. Speaking of which, all of .NET's libraries are available for use. And then there's the optional type system, used by prepending a variable with the [type] in brackets. As a bonus, all objects are .NET Objects, and most code also works as C# code, so if you really like your script it should be pretty easy to compile.

[@vindarel]

Nitpicks: "a dynamic language": true, but keep in mind that Common Lisp is compiled! *We can create standalone binaries* Moreover, the write-compile-test cycle is extremely short, because we can compile our code function by function and have compilation warnings and errors nearly instantly. We also have an interactive debugger which allows us to resume the computation from anywhere in the stack O_o "dynamic typing": true, but as always with CL it's more complicated. By default, good compilers like SBCL inform us of type mismatches. Unlike barebones Python. We can add type annotations, and we can use the new Coalton library to have Haskell-like types on top of CL O_o To get started, you can use good to very good plugins for VSCode, Atom, Sublime, Jupyter notebooks, and more! In addition of Emacs and Vim, of course. I recommend to look at the CL Cookbook. "format t …" here t means standard output. Using nil would create a string. At the end, you say to run the code with "clisp app.lsp" but we installed the SBCL implementation :) So, just use SBCL. CLISP didn't see updates in a long time, it's good only for getting started. (also, file names are .lisp today) --- Something worth mentioning IMO is that CL is still used by many companies, huge or small, for some it's their secret weapon: Quantum Computing companies, Google (for ITA Software)… see awesome-lisp-companies. And it was sent in space for the NASA in the 80s!! (Remote Agent Experiment)

I think js is a scripting language by design so it can be embedded in browsers easily.

[@NathanHedglin]

Python has no reason to be JIT or compiled. There is Cython if you really need it to be. JavaScript is very dynamic. All that must be done at runtime. Compiling only to change it later doesn't make sense. Compiled languages make certain guarantees like a type won't change. JavaScript JIT engines can optimize the code as it runs.

This made me once again mourn the fact that I can't use Clojure in my day job.

[@otakusong66]

“defun circum-size rad” 💀

Lisp can either refer to a speech defect or to an outdated programming language nobody uses anymore in the job market.

[@GeinponemYT]

I can imagine being "circum-size" not being fun, or being "defun" 🤣

Joma started programming with Racket which is a lisp dialect to interplay with modern operating systems.

Why I have a homework this week about lisp and I never understood where lisp name came from... This unblocked me... now it make sense

I was waiting for this one

What is missing is REPL driven development. This really boost productivity. Imagine you can edit live running program without restarting the program. I can't find the tutorial on youtube for Lisp + vscode + REPL driven development.

just install emacs

@@bhavyakukkar with vscode should reduce entry barrier. No need to learn another editor.

[@bhavyakukkar]

@@yusufmalikul one half of learning that new editor will be learning lisp

Makes me feel like I know nothing about functional programming when I pass a method to a LINQ Select method
