>why people prefer less powerful languages to the more powerful

Clearly, power is the only measure one should consider when picking a programming language. And Lisp surely has more power than Go. I'm going to guess 36.1% more power, to be exact.

>and what can be done about it

We could always start performing eugenics to get rid of them.

... Okay, I apologize for being an ass. But I hope my points aren't lost; the way you're phrasing things makes it feel like you're bitter that anyone would consider using something that's not Lisp.

>I'm going to guess 36.1% more power, to be exact. Where's this figure from?

>We could always start performing eugenics to get rid of them.

I meant more like what we could do to improve the more powerful languages to make them more appealing.

I'm less bitter than I am perplexed about the choice to use Go over Lisp.

[jchw]

It was sarcasm. Obviously one can't objectively measure the power of two languages. I assume you mean it has more powerful metaprogramming than Go, which is what everyone else is saying.

But I find the rhetoric quite closed-minded, because I doubt any of the people replying here who've just found out about this and are calling it a bad idea have actually tried it yet. Clearly, there are advantages to Lisp that you would lose if you tried to do something in Go. But nobody is acknowledging the reverse, that there may also be advantages in Go to Lisp that are unforeseen, even for this specific task.

All in all this is a disappointing development. I don't think it would go over the same in other text editor communities, because people seem very defensive about the use of languages in place of Lisp where they might not be so defensive about the use of languages in place of say, VimScript.

I think GP's idea was that having a more flexible language is specifically useful for configuring Emacs, not that Lisp is better than Go in every imaginable case.

[jchw]

I haven't tried the linked package, but it seems like the idea is that it can be used alongside Lisp. If so I'm not fully understanding how this isn't a reasonable idea. Surely _being able_ to use Go is not a bad thing and not useless?

[armitron]

In practice, it's close to useless. A lot of the power of Emacs comes from the homogeneity and that Emacs itself is mostly written in Emacs Lisp.

There have been attempts in the past to do similar bridges to Python and Javascript IIRC, but they ended up nowhere since they didn't mesh well with the existing ecosystem.

No matter how bad people think Emacs Lisp is (an incorrect impression, Emacs Lisp has improved tremendously) it's still a powerful Lisp and only a Lisp would provide the powerful extensibility that Emacs has.

[jchw]

I don't think the author is challenging most of the notions here. In fact, it seems pretty well inline with this.

I think language bridges suck, but this isn't one. It transpiles Go to Lisp bytecode, making it much closer to a first class citizen.

But more importantly, the tagline of the project isn't "Let's write Emacs in Go," nor is it "Emacs Lisp is bad," it's "Not a fan of Emacs Lisp? Hack Emacs in Go!" -- that seems pretty straightforward to me. The aim of this seems to be potential Emacs users who do not code Lisp and don't like it. There are plenty of reasons to not like Lisp, not just Emacs Lisp, including the power that it possesses, just like there are plenty of reasons to not like Go. To suggest otherwise would be elitist.

The way I see it, the potential here is to open Emacs scripting up to a wider audience of people who are not necessarily all the same kind of programmers, who may prefer more typing to more magic.

> There are plenty of reasons to not like Lisp

Would you please list those reasons?

[jchw]

I hope you're asking in good faith and don't really think Lisp is actually the best at everything.

Since you asked though, I'll go into my personal list. You'll note that much of these can just as easily be advantages depending on the situation and I'm by no means saying that this list applies to all things and all people (in fact it objectively doesn't.)

- The syntax: duh. Its elegant in how it mixes code and data, and unifies so much functionality into one syntax. But it has a number of disadvantages. One, the number of parens is cumbersome. You can get used to it, but it's still cumbersome. Two, it isn't always intuitive; sometimes infix syntax just plain feels ergonomically better, all flaws aside. This can absolutely be said about math. Lisp takes order of operations out of the picture, but the same would be true if you threw a shit to of parens into any language, so I feel that doesn't count.

- It's absolutely magical. It's so powerful that I wouldn't trust most programmers to wield it. It's so powerful I wouldn't trust me to wield it. I like programs that are obvious. One of Go's strengths is that it is very stupid, for example, leading to stupid code that is stupid readable by anyone (even if they're.. you get the idea.)

- Lisp feels like the world of wheel reinvention. I don't​ know if that's due to the language or the community that surrounds it, but I'd guess it's at least a little bit of both.

- Lisp is a dynamic language. By nature this is going to mean you can do less things with code statically. I'm a big fan of static typing for the obvious advantages it brings to larger projects.

- Finally, comfort. Lisp is obviously a language that has stood the test of time, but even despite that Lisp programmers are far and few in the industry. Most people are going to be familiar with imperative programming languages based off of C like syntax, or maybe something closer to Python. Either way, if you pick a random programmer off the street, you wouldn't assume they knew Lisp. (Unless their beard was really long.)

It's a lisp. That is enough for a lot of us to want to use another language, irrespective of how much Emacs lisp improves.

[lispm]

If you don't like Lisp for editor programmoing, then an editor which is literally built upon a million lines of Lisp code seems to be a very bad choice. Even providing another extension language won't make the Lisp go away.

[vidarh]

The implementation language does not matter to me - I'm not working on the code base, and have no interest in doing so. I don't care that there is lisp there, as long as I don't have to write it.

[flavio81]

You should try digging deeper into Lisp before disqualifying in such a frivolous way.

[vidarh]

You're jumping to conclusions you have no basis for.

[nbouscal]

'Not useless' is not a high enough bar in software. Flexibility always adds complexity, and complexity is a cost. Sometimes that cost is worth it, but the benefit needs to be much larger and clearer than 'not useless'.

[jchw]

Not a high enough bar for what exactly? So far this entire thread is a lot of vague talk spawning off the idea that it doesn't solve a problem. That's the statement I don't agree with. If enough people decided to use it, that's the only bar that actually matters. But it clearly solves a problem, just not necessarily a problem every Emacs user has.
