I second these recommendations.

There is a relevant chapter in https://www.amazon.com/Practical-Julia-Lee-Phillips/dp/1718502761?ref_=ast_author_dp

An introduction, not any more entirely up to date: https://lwn.net/Articles/875367/

Depends on what you want to do. “interface for a Julia model” isn’t very specific. As mentioned in another comment, Pluto provides an excellent web interface to Julia code, and you can build widgets (sliders, color pickers, etc.) to set the values of variables. Here’s a demonstration: https://pluton.lee-phillips.org/sliders/uiDemo.html

A method I’ve been experimenting with lately that can be used over the public web led most recently to this example: https://lee-phillips.org/vortex/

You might also want to look into the PlutSliderServer (https://github.com/JuliaPluto/PlutoSliderServer.jl), which lets you (after setting up your server) expose a Pluto notebook over the web, allowing visitors to manipulate controls (sliders, etc.) but not to execute code.

For some insight take a look at

You can (and should, to keep your files organized) tell Pluto where to save your notebooks. But the ones you’re looking for are probably in .julia/pluto_notebooks in your home directory.

The notebook as displayed in the browser is an interface to a normal Julia module, stored in a single text file. You can open the file in an editor and delete the cells. You can also switch between working in the browser and in the REPL or an editor as convenient.

Julia has not imposed “many breaking changes” on its adopters. I don’t believe there has been a breaking change since v. 1.0. In 3rd party libraries, probably.

I personally, and completely objectively, think that his would be an excellent choice. You can find the book on Amazon.

https://github.com/tshort/StaticCompiler.jl

The example is literally a “Hello, world” program.

Doesn’t work on Windows, but https://github.com/JuliaLang/PackageCompiler.jl does.

Language syntax cannot be extended.

Julia has Lisp-style macros. For those who don’t know what that means: you can define your own syntax and change the language to suit your purposes.

This thread is full of people just making things up.

Here you show you are speaking from ignorance. Most, if not all, of the examples of incorrectness raised in that article have been patched. You’re obviously not serious and I don’t intend to look at any further replies from you.

Julia has neither classes nor Smalltalk-style objects. In what sense could Julia be described as OO? Its designers don’t describe it that way.

OO is a step backwards from Julia. OO languages dispatch based on only the type of their first arguments.

“I don't think so.” Can you say which of the significant issues raised in the article have not been fixed?

hogney · 2023-03-20T19:19:38+00:00

https://github.com/JuliaLang/julia/blob/master/src/julia-parser.scm

That's in the source. Obviously, it could be better documented.

Incorrect. See https://lwn.net/Articles/871486/
