Damn. This is amazing. £325 per week, paid monthly, for 3 years - and the result was a profit for the Irish economy:

Post from Threads user rodneyowl: "Ireland has declared the Basic Income for Artists scheme permanent. This will be officially announced in tomorrow’s budget. Details to follow. Congratulations to all who fought for it and the present and future artists of all sorts in Ireland. That includes me 👌We’re just comin to the end of a 3 year pilot scheme. It’s been a roaring success. For every €1 paid out to the 2000 participants, the government got €1.46 back. Can’t argue with that. Other countries are already taking note."

Haha 😂
lo1tuma has been around in that domain a long time as well. I think we interacted around linting rules for mocha or something like 7-8 years ago? Good to have such a person helping out with the project!

I'm still amazed that more people don't use comby.dev. Just used it to do a complex refactor on a little under 1k Elixir files and it took me nearly 0 effort to do so.

That's really not a lot of money. I'd even say that 0,000 is... no money.

(I imagine the first digit was removed by mistake)

Jeroen Engels @jfmengels.bsky.social · Aug 25

Didn't know about this (not a Next user) but yeah, removing it sounds like the way to go.

Why would you want to search for anything if we recommend you such great content when you load the page?

It's a fish?!

Jeroen Engels @jfmengels.bsky.social · Aug 24

Some questions I have:
- Are there any benchmarks that show it's faster?
- Are there any API differences? Differences in results? Or tradeoffs?
- Why make a separate package and not contribute these to slice-ansi instead?

Over 600k loc of Elm last time I checked.

Congratulations team! Great work!

Mainly about linters and Elm.

Jeroen Engels @jfmengels.bsky.social · Aug 20

It's not a bug, this is an intended feature. But boy is it an anti-pattern.

Jeroen Engels @jfmengels.bsky.social · Aug 19

For instance, I haven't seen a better linter out there than elm-review, and I have looked! (speed of the tool notwithstanding, it's okay at best).

No side-effects, no impure FFI, etc. all make for really easy maintenance and features. Lamdera is amazing and could not work as well given side-effects

Jeroen Engels @jfmengels.bsky.social · Aug 19

It works just fine for us and a number of other companies. As you say, Elm is not a general purpose language, it is for web applications (though I have some success for using it for a linter).

The removal of signals and other features comes at a cost, yes, but it also comes with some great perks.

The creator is still working on it but not in public. There hasn't been a release in a long time, most of the improvements have therefore been in the ecosystem (I'm working on its main linter). It's not dead, though it has shrunk over the years. It's still my favorite language by far.

Super interesting!
Do you know which rules get removed in practice? Is it like rules that only care about TypeScript types for example?

(Yet another case of other linters not supporting such an automatic fix because of potentially removing side-effects and therefore altering code behavior)

Jeroen Engels @jfmengels.bsky.social · Aug 18

Working on an automatic fix for elm-review's NoUnused.Parameters rule, removing issues even across multiple files.

It's going to be glorious!

NoUnused.Parameters: Parameter `maybeCred` is not used You should either use this parameter somewhere, or remove it at the location I pointed at. I think I can fix this. Here is my proposal: Followed by edits in 3 different files.

Are there so many rules that look for such specific nodes to make for such a big performance change? That's quite surprising!

Jeroen Engels @jfmengels.bsky.social · Aug 17

Possibly yes, but it still wouldn't work for censored code that you would like to avoid touching at all.

And yes, only looking for syntax errors is not super useful, hence why I think a config-less run is not so interesting.

Jeroen Engels @jfmengels.bsky.social · Aug 16

I linked to this in another reply thread but maybe this could be of interest to you @joshuakgoldberg.com. It has worked wonders for elm-review, though dependency management will likely not work as easily for you. I would highly recommend a similar feature.

Jeroen Engels @jfmengels.bsky.social · Aug 16

(Also, it's super useful to try out PRs with bugfixes before a new version gets released)

Jeroen Engels @jfmengels.bsky.social · Aug 16

Do note that for elm-review we have this feature linked below.

It allows people to try out configurations, or to init their configuration to that.

Given this, I think it's okay to not have a config-less run, but I agree that this is missing for ESLint.
