Sounds to me that they will build some sort of hosted service or maybe PaaS based on the Deno runtime (like AppEngine or AWS lambda), but yeah it's pretty vague.

> Also, the post states that you can't have nested "tail-call optimized" loops in clojure, which is only partially correct: Using nested loops is commonly done in Clojure, the only thing you can't do is have the loops

Elvish author here, glad that you like it, and thanks for the plug :) To save people a search, here's Elvish's homepage: https://elv.sh

Or use Elvish, which has builtin directory history :) Directory history is the 3rd demo on the homepage: https://elv.sh/

If you have a long expression, you can break it into multiple ones by storing some intermediate results in another cell. You can also hide such cells or put them in another sheet. This might sound like a hack, but being able to see intermed

A tangential point, but I find it weird and somewhat amusing that an article on US Google employees should use a photo of Google's London engineering office. Maybe they don't have a good shot of a lot of people standing in front o

Elvish and PowerShell shares one big thing: let command outputs carry structured value. Everything else is quite different: * Elvish is a more minimalist language influenced by the Lisp tradition, whereas PowerShell is a much larger languag

Thanks! Is there anything you particularly like, and anything that can be improved?

Yes, Elvish's $nil maps to JSON's null.

by xiaq 6y ago
Elvish has a really simple API for writing completers ( https://elv.sh/ref/edit.html#completion-api ). The simplicity of the API stems from some fundamental language features like first-class functions, value pipes and c
132.
by xiaq 6y ago
Yes, Elvish now has a dedicated number type, so conversation from JSON is now lossless.

No. If you are looking for a POSIX-ish shell with modern features, Oil ( http://www.oilshell.org/ ) is your best option.

fzf is indeed a very neat standalone tool, and for the use cases it has been optimized for, it is superior to Elvish's UI in many aspects. However, Elvish also has a very expressive programming language, and eventually it will offer mo

A belated disclaimer: I work for GCP, but not this product.

Yeah, I agree that YAML is not the best language for embedding a DSL, but in general GCP seems to have a preference for using YAML in its configuration languages. I can imagine that the developers chose YAML based on its popularity elsewher

Well, that was a contrived example. Something more useful would be e.g. enumerating all the HTTP endpoints being depended on, or calculating the maximum resource consumption. I think our disagreement really boils down to different approache

The actual question being asked and answered here is why a mile is defined as 5280 feet, as opposed to any other number, such as 5000 feet.

Yes, the orchestration code can be developed and debugged as normal code. I agree that it can be a pain to write and debug YAML "code". But what's usually more interesting when it comes to workflows is inspecting and debuggin

by xiaq 6y ago
But what this does under the hood is still sending instructions to a workflow engine that does the actual work, as opposed to this code doing the actual work directly, right? If that's the case, then what you could do is still restrict

Saying this is reinventing BASIC in YAML seems to miss the point here; the programming model here is essentially a finite state machine with optional data flowing between nodes, and AFAIK there isn't really a widespread language that t

Shameless plug: if you like the idea of processing structured data in a shell, you might also like Elvish ( https://elv.sh/ ).
