Add JSON schema for config file

[binyamin]

Provides a JSON schema for the wails.json config

Resolves #1851

Notes

Along with publishing a schema, I feel that a few more things would be useful

• A project member should probably ensure the schema is accurate
  • I tried my best to review the docs & code, but it's always best to be safe
• When the user runs wails init, the config file it creates should include a link to the schema
• The website should note that the schema exists. Maybe on /docs/reference/project-config.

Hey @binyamin 👋 Apologies for being a bit slow getting back to you on this. Happy to review this. What did you mean by The wails init command should link to the schema in the config file it creates?
Feel free to update the docs in the website directory and let me know if you need a hand with that 👍

Looks good so far! Just a couple of comments. Thanks so much 🙏

So these osHook keys are actually the format of the keys rather than explicit values, EG: windows/* or linux/arm7. I'm not sure how you represent that in JSONSchema!

[binyamin]

True. I could have validated it against a list of all possible os and arch values. Instead, I chose to add some dummy keys for explanation (lines 182 - 190). The keys are matched against a RegExp at lines 192 - 202.

Just FYI, the title key is mainly used for intellisense & documentation. It's doesn't mean you actually use "title" in the schema.

I edited the top comment. Let me know if it's still unclear.

[leaanthony]

Do you mean update the generated wails.json files to include the schema reference? What would that look like for e.g. this file? If you give me an example, I can do some search+replace fu 👍

[binyamin]

@leaanthony it would look like this:

{
  "$schema": "https://wails.io/schema/config.v2.json",
  "name": "{{.ProjectName}}",
  // ...
}

@binyamin - I've added the schema references + updated the docs. Let me know if you feel this is good to go and we'll get it merged 👍

[leaanthony]

Let's go!

Thanks for taking the time to do this. It's a fantastic addition 👍
