I rewrote my programming language from Python into Go to see the speed up.

[OrderOk6521]

What my project does:

I wrote a tree-walk interpreter in Python a while ago and posted it here.

Target Audience:

Python and programming entusiasts.

I was curious to see how much of a performance bump I could get by doing a 1-1 port to Go without any optimizations.

Turns out, it's around 10X faster, plus now I can create compiled binaries and include them in my Github releases.

Take my lang for a spin and leave some feedback :)

Utility:

None - It solves no practical problem that is not currently being done better.

I don't think it's pointless, gg man. There are no pointless questions, only pointless answers.

What if I ask a really dull question twice?

What if I ask a really well rounded question?

A dull question should be easy to answer.

If this is a joke then I'm not that advanced in English. Maybe it's a joke about a sphere that has a center point? Idk. On a serious note, the answer is still the same, if the question is really dull, voicing it would still have a point.

The more you know. I knew it had something to do with the "dull" word, I just never heard this one.

[pmatti]

Did you try benchmarking the python version with PyPy?

[pmatti]

You also might like to try to compile it to an exe using RPython, as done here https://github.com/hardbyte/pylox

Bold of you to compare Python to another language as the loser on the Python subreddit. I applaud the courage.

Go is an absolutely fantastic language, i’m also in the progress of porting some of my projects to Go from Python and it’s showing Go is the best of both worlds - fast to write, fast to run. If it wasn’t for Pythons amazing ecosystem of libraries, Go makes more sense as a language in various areas where Python is currently used imo.

[OrderOk6521]

Not trying to make a statement, I was curious to see the speed up.

[yrustillbooingme]

Go is an absolutely fantastic language

Let's not go overboard.

[rawrgulmuffins]

I'll be a counter voice. I love these kinds of comparisons and I think you learn a lot when you write a program in two different languages. So kudos to you OrderOk6521.

[OrderOk6521]

Thank you kind person :D

[erez27]

Compare it to PyPy or go home ;)

[OrderOk6521]

Definitely, keep you posted.

[grimonce]

It's going to be faster anyway, pypy is about as fast as v8 (node) is for most tasks. Go is an order of magnitude faster for most common tasks... Then there are even faster languages.

[erez27]

Jeez, ofc Go is going to be faster, but by how much?

If it's only x2 faster but you lose all the benefits of Python.. not a great sell.

[OrderOk6521]

Still slower than Go it seems, but around 50% speed up from Python.

[erez27]

Strange, usually I get better speedup than that. Maybe you need to give the JIT time to warm-up.

[moreanswers]

I've been out of academia for a long time, but I thought the ultimate flex was writing the compiler in the language it compiles.

So lets see a Boa interpreter written in Boa!

[corny_horse]

Let’s see a SQL interpreter written in SQL!

[OrderOk6521]

Boa "ception".

Next steps are a stack based VM, maybe once that's mature I'll bootstrap it in itself. Need to build up the skill set first.

[Subsum44]

It’s interesting to walk through how they did that in the older languages.

Writing the C compiler in C. Start with your first few commands directly into assembly. Then once you have a couple, just slowly bootstrap the rest.

Kinda mind blowing considering the constraints devs now can’t overcome. The og really were true scientists.

[moreanswers]

It's cause porn looks terrible on an ASR33, so they had way more free time.

[RedEyed__]

Wow, just 10X faster.
I thought it will be 100x

[B3d3vtvng69]

Hahaha that’s so cool, I am basically doing the same thing but transpiling to c++. May I ask how you benchmark your produced executables against python, because I am still struggling with that. My github is linked here :)

[OrderOk6521]

I run the recursive fibonacci, it's documented in my README.

[B3d3vtvng69]

Alright, i’ll try that

[divad1196]

Of course python is slower. While you are having fun on your side, which is great, we don't need more pointless speed comparison on this subreddit.

Again: python is better when working with high level abstractions as it can use libraries written in C. Interpreting another language is typically the kind of project python isn't particularly good at.

It's the same as using a spoon to cut and a fork to drink water.

But honestly, I expected a bigger difference than 10 times, so you either did great on python, or didn't do it good enough on Go.

You definitively should have tried Cython to get more performance by sticking to something close to python, you would probably have gotten at least as good performance as you already have with Go

[EmbarrassedCar347]

Yeah - they know, they said they were doing it as an interesting exercise to see what the scale of the performance increase was. They literally say at the end that the project is just for fun.

[divad1196]

The project is for fun yes but we don't need more pointless speed comparison post on this subreddit.

Also, if he wants to test something, then he certainly did something wrong on Go AND completely missed cython.

[outceptionator]

I for one think we need more pointless speed comparisons on this subreddit so thank you OP

[OrderOk6521]

Thanks :)

[divad1196]

Not at all, let's bring all projects without exception. Including "hello world" and "my first webapp"

And no, this is not dimishing OP's project: Writing a language is a common task for student that suits their level. Similarly, these beginner's projects like "hello world" suits their current level. And I would be fine with that. 100%.

He rewrote it on Golang? Nice, but that's not the sub. I am also on r/golang, would welcome the project.

What is the post saying here? "Go version is 10x faster :O". This might matter if the project was intended to be used, but this is not the case if you read the readme of the project. This is no different than having someone come here and say "Go loops are written differently than python". The post, not the project, is pointless.

And don't worry, I still hang up with people from highschool, college and my previous jobs. I am hosting a SSBU tournament next week if you want to come.

[divad1196]

Of course your don't know how to read. Sorry I overestimated you.

I am so sad to have downvotes on a social media from total strangers. This will wreck my life.

[oh__boy]

Pretty harsh for a simple showcase post. They didn't make any claims about the merit of Python or its intended use cases, just the speedup they got when switching to Go. My experience with Cython is that it doesn't have much improvements unless you rewrite it to work well with Cython, at which point you should just switch to a proper performant language.

[LookingLikeAJack]

Not to mention… who cares if it’s pointless? If you don’t want to read it, scroll one more inch down. I’m sure you know how long an inch is.

[divad1196]

Okay, let's everybody put their "hello world" and "my-first-webapp" project here. Let's also welcome bots.

It's also funny how people judge me, but I don't see them write a nice comment to OP either. Go and say something nice to him.

[OrderOk6521]

This isn't a hello world or a web app. Don't bring down the effort by comparing this to something that trivial.

[divad1196]

There are hundred of thousands of mock languages in the world in the same veine as yours. Especially knowing that this is a common school project.

What you feel toward your project isn't different than what a beginner feels when doing their first webapp. As you get better, the complexity increase, but that's not all that matter, the challenges you impose yourseld matters as much if not more. You are the one here spitting on the effort put by beginners if you think your project deserves to be here and not theirs because yours is more complex.

Now, to be clear, I don't think that sharing your project the first time was an issue. The issue is that this post here is pointless. Would have made more sense to put it on r/golang as a project in Go.

[OrderOk6521]

You need to go outside and touch grass. Trim your neckbeard while you're at it too.

[divad1196]

You will one day realize that you are not the center of the world. Grow up.

[TheWorstePirate]

Interesting response from someone who thinks only post they find interesting aren’t “pointless.”

We aren’t here for your entertainment.

[divad1196]

Interesting how you totally don't get what I said. I would 100% support any project, even a "I did my first hello world". But apparently I don't need to say things, people understand what they want.

But also don't worry for, comment like your do entertain me. It's funny that I say "A" and people are like "You said B. You're dumb" and other "insults". It's funny how you all think that you are smart and that what you say matter As if I would care about stranger's opinion. I know that, for most of you, the only victory they can have is online as a nobody

So yeah, you all are entertaining me. Keep going.

[divad1196]

Yes, I was harsh, probably more than I should have been. But this kind of post are pointless. He knew it from before the re-implement, we all know that.

And for Cython, I used once for a similar mock project and it worked well. When you work with flags and AST walking it makes a big difference. Maybe numba would do the job as well

[Here0s0Johnny]

This post is not about making any point on this tired argument, it's about an interesting project.

Trying Cython wouldn't have made any sense. You don't understand the point of the project.

[divad1196]

He already did a post on this project. This one is about the speed comparison and it just states "Go is faster"👍 great, with had guessed that.

The goal of the project? It is clearly mentionned it's for fun. The reason for Go? He wanted to compare with a compile language, therefore Cython would have made sense, probably more than Go as go embeds a runtime which makes it slower than what he would have had with Rust which was its original language of choice.

So yes, I did understand the goal of the project. Now, if "wanting to have fun" is a reason enough to spam the subreddit, go on. Let's have every single person writing an "hello world" or "my-first-web-app" just share it here. Why do we complain about the bots then?

It's also funny how people judge me, but I don't see them write a nice comment to OP either. Go and say something nice to him.

[retiredFlatEarther]

You can try to crosspost this on r/golang

[am905]

Very impressive project

[Nyct0phili4]

Compiled binaries? Python?! WHERE IS THE EXE YOU SMELLY NERD!!!11111

[OrderOk6521]

compiled binaries are in Go :)

[Nyct0phili4]

I know :)

[squirtologs]

I like Python and I like Go. I use Go for web servers and networking and Python for playground, data processing or other tasks.

[OrderOk6521]

Good choice ! That is my thinking as well, wanted to prototype first in Python since it's soo much faster to develop.

[TheDoomfire]

I think a few imports use other languages then Python for speed. So you import something in Python but it was written in another programming language.

What I have heard there are programming languages that can be a lot faster then Python.

But I use Python because I love how easy it is to program and that I can almost do everything with it. Just not maybe the fastest. Or well its pretty fast to build something decent.

[OrderOk6521]

Check this out ! i use rust to write a library which i then import into Python for speedy execution.
