Support installing go modules

[nalgeon]

Anton, thanks for your interest! Do you want me to prepare a dedicated Expr sandbox so you can use it in the Getting Started guide and other parts of the documentation?

As for go.dev/play, I don't think it supports installing modules. Quoting the docs:

The playground can use most of the standard library, with some exceptions. The only communication a playground program has to the outside world is by writing to standard output and standard error.

Installing arbitrary modules in the sandbox would be too slow (and insecure).

Here is an example of playground: https://go.dev/play/p/XCoNXEjm3TS
It installs github.com/expr-lang/expr inside it.

If you could add support for Expr it will be super cool =). I can use it in https://expr-lang.org/docs/language-definition

It installs github.com/expr-lang/expr inside it.

Ouch, I was not aware of this feature! Still, I'd rather not allow arbitrary modules (yet).

I'd love to add Expr support, though! In fact, I have already done so (the name of the sandbox is expr-lang).

I think you can use this sandbox both for full-blown Go examples (on the Expr Home and Getting Started pages) and for expression evaluation (Language Definition page).

I've prepared some examples:

• Home page
• Getting Started
• Language Definition

I'd send you a PR, but it seems you're using Docusaurus, and I couldn't find the documentation build config or tasks in the Expr repo to check everything locally (integration with Docusaurus can be tricky sometimes).

[antonmedv]

Oh! Awesome! Yes, docusaurus site is in private repo right now. Will try to integrate those today.

[nalgeon]

Awesome! Let me know if you have any questions in the process.

As you probably know, Docusaurus' "markdown" is not really markdown (it is handled as a React component).

So it does not play well with web components (which the Codapi widget is) or templates.

Please see this guide for using Codapi with Docusaurus.

If you're testing on localhost, port 3000 is allowed to access Codapi.

@antonmedv Any luck integrating Codapi? I'm happy to help if you have any questions.

[antonmedv]

I was able to integrate it, but I need to figure out a better editor for expr.

[nalgeon]

Codejar maybe? It's a perfect fit for interactive examples, IMHO. I use it on the codapi website.

[nalgeon]

Okay then. Let me know if you have any questions.
