Elm Alternative Package (Mirror) Live

via Elm - Latest posts by @turboMaCk Marek Fajkus on Thu, 03 Feb 2022 16:24:59 GMT

@rupert elm hardcoding domain would not be a problem. That domain would just got resolved to your IP. But then the certificate for https would be a problem because you can’t have valid one for that url. There would be way around that by installing certs but at that point main complications would be still with installing certs probably making simplifications insignificant.

Anyway I’m happy to say I made it work with mitmproxy as described relatively easily.

Elm Alternative Package (Mirror) Live

Not sure either of those would work. /etc/hosts because the elm compiler already has package.elm-lang.org hard coded. And DNS because its https and the compiler is checking the certificate is correct.

It has always been the plan to do a modified compiler for this project.

Does it make sense to rely on JS libraries for simple effects s.a., Collapse?

Elm Alternative Package (Mirror) Live

As part of my work on an alternative package manager for Elm, I have updated its package index.

You should be able to run a build through it by doing the following:

> mv ~/.elm ~/.elm-old
> mitmdump --ssl-insecure -M '|https://package.elm-lang.org/|https://package.eco-elm.org/v1/'
> https_proxy=http://127.0.0.1:8080 elm make src/Main.elm

There is also a step needed to whitelist the mitmdump certificate authority on your local box to allow it to proxy an https endpoint - you can find instructions on how to do that here https://docs.mitmproxy.org/stable/concepts-certificates/. This is not something you should do without considering the security implications - I am ok doing it on my dev box, but not on CI through to production.

Moving your current ELM_HOME folder ~/.elm out of the way is needed, since the .zip files on my package server are different again to the ones GitHub serves. They have been stripped of everything except src/**/*.elm + README.md + LICENSE + elm.json. That is why I put (Mirror) in brackets, because it is not an exact mirror.

Currently running on a minimal AWS infrastructure, so it is not very responsive, so don’t hit it too hard.

I would be interested in hearing if anyone else is able to get it to work? or what errors you encounter when trying.

Removing the need to use mitmdump would require hacking the Elm compiler, since it hard codes https://package.elm-lang.org/. I will try and publish a hacked compiler soon (with the publish CLI option disabled), to make reaching this package mirror simpler.

Simple CSS transitions in Elm?

It’s certainly not perfect, but it works in this use case as I know there’s a limited number of items. So investing in a perfect solution is not a good tradeoff here for me.

Feel free to post an elm-animation solution for academic purposes, though! I am sure others searching for a similar answer will be grateful.

I’m sure it is, I just like to have as few dependencies as possible. For a first Elm app I’d like to see if I can build it in pure elm without any additional packages at all!

A GitHub action to avoid being caught by GitHub zip issues on CI

via Elm - Latest posts by @mattpiz Matthieu Pizenberg on Wed, 02 Feb 2022 11:31:56 GMT

Hey guys! I’m just hearing about the zipball issue on GitHub preventing elm make to run. Turns out if your packages are cached, you don’t need to download them So ironically, GitHub actions caching are a solution to GitHub problems if you are using GitHub.

Some time ago, I published an action to help you do exactly that so I thought I’d relay it again today: GitHub - mpizenberg/elm-tooling-action: GitHub action to install Elm tools and cache ELM_HOME

The action is pretty nice, since it just requires you to add an elm-tooling.json file like this:

{
  "tools": {
    "elm": "0.19.1",
    "elm-format": "0.8.5"
  }
}

and to add the following few lines to your .github/workflows/ci.yml file and you are set! (Don’t forget to activate action both on PR and main branch).

      - name: Install elm, elm-format and cache the ELM_HOME directory
        uses: mpizenberg/elm-tooling-action@v1.2
        with:
          cache-key: elm-home-${{ hashFiles('elm-tooling.json', 'elm.json') }}

Couple remarks

There is a warning saying that you shouldn’t use it if you have a typical web project with a package.json file and follow instead the traditional elm-tooling-cli setup.

Well it was me being over cautious, and it seems that both are fine together (let me know if you have issues). So you can add the GH action just for the sake of easy caching of the elm home.

It doesn’t seem to be up to date

It is enought up to date if you are only interested in caching, elm, and elm-format. If you also want to install the latest elm-test-rs with it, I haven’t updated it yet by lack of time. PRs are welcome, please make it so I can review very easily because I don’t have much time these days.

I hope your projects are back to normal compiling! Otherwise have a look at Martin’s script to build your own cache! Build ~/.elm cache manually without checking SHA1 hashes · GitHub

And continue building with elm

Travelm-Agency now supports Fluent including usage of the Intl API with Elm 0.19!

I am of two minds about this. On the first hand, this is both very neat and very impressive. On the other hand, intl-proxy scares me, because it brings back (somewhat limited) JS FFI and thus a lot of the concerns around Kernel code.

I have also dabbled in Elm-generating-Elm, and believe that whatever hacks you want to use during that are fine, because at the end of the process you either have valid Elm code or you don’t. However, I see in the examples that some use cases require the use of intl-proxy in the application that uses the generated code. Would you consider moving to a pure-Elm solution for locale-aware formatting if one was available?

Blatant plug: I started on such a pure-elm library, although it is not feature-rich enough yet to cover this use case: elm-cldr 1.0.0
