In what specific areas Phoenix Live View is so far ahead? Do you mind elaborating?
The unfortunate disadvantage of Live View is that you need to write Elixir. A lovely language, but it would be hard to sell in company that use only <SOME_LANGUAGE>. The hypermedia libraries like d* and htmx can be used with any backend.
I like the idea of bundling Lua with bunch of batteries but the syntactic changes go too far. They seem to be lousily designed attempt at turning Lua into Typescript.
For example coalescing operator. You can do the same in standard Lua with or. Pipe operator might seem like cool idea, but the language needs to be designed around it (Elixir) or you need multiple variants (threading macros in Lisps).
Yeah, there are a lot of odd inclusions like that; things that overlap or replace standard lua flow for no reason (see ternary expressions[0]). I would love an expanded lua, with built-in classes and a more robust standard library, but this feels more like a rewrite into a new langauge with two vastly different design philosophies layered awkwardly on top of each other. Which it is I guess.
I don't mean to discount the work that has gone into it, and there are a lot of really neat features here. But honestly I think it would be stronger as a standalone thing, without all the lua baggage, given how far idiomatic pluto diverges from idiomatic lua.
local function report(result)
print(result ?? "The value was nil.")
end
report(filesize("/path/to/file/of/length/zero"))
If filesize returns nil for file-not-found and the length otherwise. Wouldn't coalescing work and or would not be able to identify existing but empty files.
As a TypeScript fan, I was really happy to read pretty much every one of these changes. This is a language I wouldn't personally use unless it gains massive traction, but one that I hope it gains massive traction so that I can justify spending the time memorizing and learning all these new language additions.
It's particularly exciting that they constantly rebase upstream Lua, and plan to update it to be compatible with Lua 5.5. Especially because Lua 5.5 finally has the ability to turn off globals!
One painful one that is still reverberating a bit in some areas is the renaming of "SafeConfigParser" to just "ConfigParser" in the standard library (in 3.12). This caused a whole lot of breaking in some areas because versioneer (a package for determining a package version from git tags) used it (in code that was placed inside your package, and so couldn't be solved by just upgrading versioneer).
