Adds the Standard ML community extension ([omarjatoi/zed-sml](https://github.com/omarjatoi/zed-sml)) to `docs/src/languages.md`. It is already published in the Zed extension registry ([zed.dev/extensions/sml](https://zed.dev/extensions/sml)) and provides Tree-sitter highlighting plus Millet LSP integration, but is currently missing from the language documentation page.

# Standard ML
|
|
|
|
Standard ML support is available through the community-maintained [Standard ML extension](https://github.com/omarjatoi/zed-sml).
|
|
|
|
- Tree-sitter: [MatthewFluet/tree-sitter-sml](https://github.com/MatthewFluet/tree-sitter-sml)
|
|
- Language Server: [Millet](https://github.com/azdavis/millet)
|
|
|
|
## Setup
|
|
|
|
1. Install a Standard ML implementation such as [SML/NJ](https://www.smlnj.org/) or [MLton](http://mlton.org/) to compile and run your code.
|
|
2. [Install Millet](https://github.com/azdavis/millet#install) and ensure `millet-ls` is on your `$PATH`.
|
|
|
|
## Project setup
|
|
|
|
For projects with more than one source file, Millet expects a single root group file. Create a `millet.toml` in the directory you open in Zed:
|
|
|
|
```toml
|
|
version = 1
|
|
[workspace]
|
|
root = "sources.mlb"
|
|
```
|
|
|
|
The root must be either a [ML Basis (MLB)](http://mlton.org/MLBasis) file (`.mlb`, used with MLton) or a [SML/NJ Compilation Manager (CM)](https://www.smlnj.org/doc/CM/new.pdf) file (`.cm`, used with SML/NJ). Files not transitively reachable from the root are not analyzed. See the [Millet manual](https://github.com/azdavis/millet/blob/main/docs/manual.md) for more options.
