nim VS nimscripter

Twitter Sources and Hello World Sources

No Network, no JS, no Client, no Server, no API. Write plain Nim code, and Mono UI will turn it into fluid interactive web UI.

There's no sense to use NimScript. Just run plain Nim as nim -r play.nim and disable compiler outputs to avoid noise in terminal.

Something like mix of Svelte and Phoenix LiveView. # Features - Reactive, like Svelte, with compact and clean code. - Stateful Components. - Bidirectional data binding to inputs. - Multiple UI instances with shared memory updated automatically. - Fast initial page load. - SEO friendly. - Flexible deployment: Server, Browser, Desktop, Mobile. # Example Source of [Todo App Example](https://github.com/al6x/nim/blob/main/mono/examples/todo.nim) ```Nim import base, mono/core # Model -------------------------------------------------------------------------------------------- type TodoItemState* = enum active, completed TodoItem* = ref object text*: string completed*: bool Todo* = ref object items*: seq[TodoItem] proc id*(self: TodoItem): string = self.text

It's just a conversion of a tuple into SQL `where` statement https://github.com/al6x/nim/blob/main/postgres/db_tablem.nim#L135

I added description how it works in readme, please check it out, there are answers about forms and chat https://github.com/al6x/nim/tree/main/web#readme

> What does this mean? There's a runtime VM or compile time VM?

Compile time VM. It's used to run macros / templates / concepts. You can also run most code at compile time in a `static` block except for stuff that needs C calls. You can also compile the VM into a program and use it as a runtime VM (see https://github.com/beef331/nimscripter) which I do in my GUI lib. NIR should enable the compile time VM to run faster too, and possibly use JIT'ed code.

Checkout Nim! It does much of what you describe and its great. The core language is fairly small (not quite lua simple but probably ML comparable). It compiles fast enough that a Nim repl like `inim` is useable to check features and for basic maths, though it requires a C compiler, but TCC [4] works perfectly. Essentially Nim + tcc is pretty close to your description, IMHO. Though I'm not sure TCC supports non-x86 targets.

I've never used it but Nim does support some hot reloading as well [3]. It also has a real VM if you want to run user scripts and has a nice library for it [1]. Its not quite Lua flexible but for a generally compiled language its impressive.

Recently I made a wrapper to embed access to the Nim compilers macros at runtime [2]. It took 3-4 hours probably and still compiles in 10s of seconds despite building in a fair bit of the compiler! It was useful for making a code generator for a serializer format. Though I'm not sure its small enough to live on even beefy m4/m7 microcontrollers. Though I'm tempted to try.
