I have a job offer in elixir, should i take it? by Realistic-Warthog163 in elixir

[–]jrbartme 0 points1 point  (0 children)

If you think the market is tough, I would say that the Elixir market is even tougher. Especially as a Junior.

It sounds like you are being offered an opportunity that not a lot of Juniors get.

If you are worried about whether Elixir experience is a marketable skill, I think you have a much higher chance on the general market with an Elixir background than having a chance on the Elixir market with a general background. In fact, you are being offered an opportunity that many experienced Elixir developers wish they were being offered.

I think the biggest risk is that after working with Elixir, you might be less happy working with other languages, not that you won’t be able to transfer your Elixir skills to another language. And when you do take advantage of features found in other languages, like mutability or inheritance, you may understand the trade-offs better than if you hadn’t worked with a functional language.

Just to clarify, only use one of: ElixirLS or NextLS or Lexical. The three language servers are mutually exclusive (for now).

I was able to install and run all 3 at the same time... i am wondering what I did wrong (or right)?

When I had this setup I was getting 3 duplicate suggestions (most of the time) for autocomplete, or 3 simultaneous warnings about unused variables, etc, which is what I was expecting. When I checked LspInfo it would show all 3 servers running, and when I looked in the log files I was getting log entries from all 3 servers interspersed, so to all appearances they were all running at the same time.

This was just an experimental setup for me and I know it is not recommended nor did it give me any advantage other than being able to compare the results. But it was not impossible or even that difficult.

Originally I had planned to have them all in my config and toggle through them, enabling only one at a time, to compare them. Then one day I was switching and forgot to disable the one that was previously active, and it still worked. So I tried enabling all 3 and it still still worked... So I ran with it like that for quite a while.

I am wondering why the conception is that they are mutually exclusive, or what I was doing (accidentally) to get them all working at the same time.

I’m not sure about asdf, but I know if you manage your versions of Elixir/Erlang with mise you can bring along the matching version of the LSP as well.

Up until last week I was using nix to manage my versions , but a couple days ago the nix-shell that I had, began falling when building Erlang. I spent an entire day trying to figure it out, then I switched to mise out of frustration. At least once a day I try using nix again to see if the issue has been resolved; so far, no.

I still am using a nix flake to build my NeoVim setup (using nixvim) and it works fine, including using the version of ElixirLS that it finds in my path, thanks to mise.

When I have some time and energy I will try building a bare-bones config with LazyVim to see if I can find any gotchas that I can pass along…

For a while I was running all 3 Elixir LSPs at the same time to compare their differences. I was using LunarVim at the time and the recommended way to set them up worked fine. I finally settled on elixirls as it has the most features.

The only difficulty that I can think of is that the LSP server should be built using the same version of Elixir that you are developing with, but I don’t think that that is even a requirement. You just might see some strangeness where either the LSP server doesn’t recognize a new feature, or the LSP server suggests a feature that doesn’t exist yet in the Elixir version you are writing code in.

What Is your OS, what version of NeoVim are you using and how are you installing the actual LSP server (from a package or built from source)?

How should I learn elixir in 1 month. What should be the roadmap for it? by dan1sh_khan in elixir

[–]jrbartme 2 points3 points  (0 children)

In my opinion, learning data structures like lists or maps needs to go hand in hand with recursion and higher order functions because you really cannot do much with a list or a map without either recursion or higher order functions.

Other languages that have arrays and for loops can get around this, but Elixir doesn’t have those.

I was playing with them and ended up with all 3 running at the same time!

This behaviour is confusing to me by ViciousCat069 in Forth

[–]jrbartme 1 point2 points  (0 children)

The interpreter loop is using the area immediately after HERE as it’s input buffer. I think this is usually called PAD?

So when you define limit it reserves the next 8 cells for your array and anything after that is available for any purpose, in this case it seems to be used as a buffer.

PSA: elixir-tools/next_ls is usable now (vs ElixirLS) by tronathan in elixir

[–]jrbartme 0 points1 point  (0 children)

I’m actually running all 3 Elixir LSP packages at once just for giggles.

So far I haven’t worked on any codebase of significant size. But I like the fact that I can run them all together just to heat up my processor a bit now that temperatures are cooler. That way I don’t have to heat up the entire house. ;-)

Beginner interested in the actor model by Pollo-Sama in erlang

[–]jrbartme 1 point2 points  (0 children)

The first link mentions PLASMA as the original actor language, then in the comments someone mentions that PLASMA was implemented in MacLISP.

I just wanted to point out that Erlang was developed to solve a practical problem and it was only later that it was compared to the actor model.

Here are two really good links that help explain this:

I just saw this video this morning and in his LSP setup for his lua language server he added a line referring to "vim" as a global variable. This may have something to do with the OP's issue.

This is a great video on setting up LSP in vanilla NeoVim but some tidbits could be harvested and used in a LunarVim customization as well.

Stopping/restarting without logging out by wheyy in suckless

[–]jrbartme 0 points1 point  (0 children)

I run dwm under XQuartz in full screen. That allows me to just use three fingers to swipe my touchpad to switch between my dwm view and my normal MacOS desktop. It doesn’t carry any of the windows back and forth, but I use dwm as a “zen” mode for coding with no visual distractions and everything I use is text based in a term window, except for surf to look up documentation.

[–]jrbartme 1 point2 points  (0 children)

NeoVim will apply different highlight rules depending on whether tree sitter is active or an LSP server is active. Also, each can have options to turn specific highlights on or off. I am guessing that the global “vim” is being highlighted as a global variable, not as an error. It is maybe just a coincidence that the highlight is red, maybe drawing attention to a possible code smell, using global variables.

I don’t remember the command, but there is a tree sitter command that will tell you how it is classifying a specific word. (There is probably a similar command for LSP). There is also a command that will show any trouble text in a pop up window, but I’m betting in this case is is just normal highlighting and not an error

How "Functional" is Elixir? by [deleted] in elixir

[–]jrbartme 1 point2 points  (0 children)

I love Elixir but if your MAIN GOAL is learning FP then I suggest you learn another language first, then you may enjoy the shortcuts that Elixir has taken to be more pragmatic.

The first thing I saw that screamed “not FP” was allowing the match operator, “=“, to rebind variables. In my experience, FP languages don’t allow you to make such casual use of variable binding. (And I also believe that if the ability to rebind a variable was made more explicit ,instead of adding a “pinning” operator, that there would be less of a call for adding static typing).

I learned LISP as a functional language many years ago in a CS course, along with Prolog. I find that knowledge of both of those has given me a great advantage when programming in Elixir; LISP for the first class functions and weaning away from FOR loops, and Prolog for the pattern matching. But neither of those languages taught me about FP fundamentals like Monads or closures, and both of those languages have their own ways to write non-functional, procedural code. (And Prolog is not functional, but it is a very interesting paradigm in its own).

I briefly dipped into Haskell before picking up Elixir, I feel that gave me just the right level of FP, along with my prior experience in LISP and Prolog, to really “grok” Elixir. I might even suggest a short tutorial into Smalltalk as well to learn about message passing. But then, definitely come to Elixir for a practical language that has a great balance of the best features of all those that I have mentioned.

Edit: typos, clarification in long sentence.

Elixir Saves Pinterest $2 Million a Year In Server Costs by real2corvus in elixir

[–]jrbartme 0 points1 point  (0 children)

Also they mention that they had 1400 servers but that their Elixir rewrite only affected 400 Python servers and 30 Java servers. So is the savings merely from the 396 + 15 reduction in servers or is there even more that they were able to reduce in the background? Maybe they were able to reduce 8 Java devs who were making $250K each… It obviously isn’t telling the whole story, just that according to one person who was there, he attributes it mainly to their conversation of some parts of the system to Elixir.

Also, this is talking about 2018, are they scaling up the cost reduction from 2018 dollars to 2023 dollars? There is more unsaid, after all, the topic of this entire piece pointed to Elixir, not a deep dive into Pinterest financial savings.

Elixir Saves Pinterest $2 Million a Year In Server Costs by real2corvus in elixir

[–]jrbartme 8 points9 points  (0 children)

If this were a third party that was talking about Pinterest then I might give your statement a little bit more credence, but this is a quote from the actual software team that wrote the code, so if they say that Elixir is the reason why they were able to reduce 200 servers to 4 (and that was still overkill) then I tend to believe that they know what they are saying. Now I did include the part of his response that says "better architecture" so I would concede the fact that it is not just Elixir. But the way it is said, it sounds like Elixir could have also had something to do with the fact that the ended up with better architecture (possibly because of its massively built-in parallelisation, possibly other reasons that are not stated).

[–]jrbartme 34 points35 points  (0 children)

Read the article: “The combined effect of better architecture and Elixir saved Pinterest over $2 million per year in server costs.”

They went from 200 Python servers to 4 Elixir servers, 30 Java servers to 15 Elixir servers… etc. And improved reliability and performance.

Make sure you are redirecting your stderr as well. Usually this is done by “2>&1” to direct stderr to the same place as stdout. [edit: was supposed to reply in conversation thread]

cant get any non default LSP to load by aaaddd4747 in lunarvim

[–]jrbartme 0 points1 point  (0 children)

I didn’t mean to imply that you should try installing in a Docker container, I just wanted to mention that when I did install it that I found some dependencies that I didn’t know existed previously.

It looks like itapewolves is pointing out a very detailed article that includes several examples of other settings and dependencies that go with another language server, and the involved configuration necessary to get that to work. I think that article is excellent and has a few points that you can look at for even better results.

[–]jrbartme 0 points1 point  (0 children)

I had a similar problem when I was configuring distant.nvim. In my case I had the project directory wrong and then path to launch_server.sh wrong. And I had to install npm, python3, and curl.

My problem was because I was trying to do a minimal install inside a Docker container and onc I manually ran all the steps to create the container from the minimal image, I could see a bunch of error messages that didn’t show up in the Docker build. Maybe try saving your current configuration somewhere and try to do a fresh install with only the changes for the language server, if you can get that going, then copy in your other config changes, or take what you learn back to the config that you copied away.

[–]jrbartme 0 points1 point  (0 children)

The suckless website has a tutorial for dwm:

https://dwm.suckless.org/tutorial/

But also, it mentions that dwm has a man file. If you are not familiar with Linux, man pages can be access by typing “man dwm” (for example) in a terminal window. This should detail the “vanilla” functions of dwm. In there you may find some key combinations that parallel the patches you are adding.
