Works best with Hot Reload plugin

The server can infer global symbols (like references and quests), so it may be useful to extract all vanilla scripts into a separate directory inside your project (e.g. my_mod/lib) with a tool like FNVEdit

Configuration

The server can be configured in geckrc.json or .geckrc.json file at the root of your project.

Configuration options

Name	Possible Values	Explanation
keywordStyle	"lower", "upper" or "capital"	Enforce keyword naming convention: lowercase (begin), UPPERCASE (BEGIN) or Capital (Begin)
functionStyle	"lower", "upper" or "capital"	Enforce function naming convention: lowercase (getitemcount), UPPERCASE (GETITEMCOUNT) or Capital (GetItemCount)

Example

{
    "$schema": "https://raw.githubusercontent.com/WarZone762/geckscript-lsp/dev/src/geckscript/config.schema.json",
    "keywordStyle": "lower",
    "functionStyle": "capital"
}
