Functions

Argument kinds are the script values a call passes: node is a node handle, any a table or value of any kind, fn a callback.

function	acts on	what it does
`api()`	—	Every module scripts can reach, as the JSON string `balaur api` prints; a tool reads the live engine rather than a file that may be stale.
`attempt(f: fn)`	—	Call a function, answering `(true, value)` when it returned and `(false, message)` when it failed.
`check(path: string, source: string)`	—	Every compiler diagnostic about the given source, as `[#{ file, line, column, severity, message }]`; an editor passes the buffer it is showing.
`complete(path: string, source: string, line: int, column: int)`	—	Every completion valid at that caret, as `[#{ label, kind, detail, doc, insert }]`; an editor passes the buffer it is showing.
`definition(path: string, source: string, line: int, column: int)`	—	Where the name at that caret is defined, as `#{ file, line, column, url }`; engine API carries its reference page rather than a file.
`exports(path: string)`	—	The tunable properties a script declares in `exports()`, with their defaults.
`find(path: string, source: string, needle: string)`	—	Every place that text appears across the files this one's `mod` declarations reach, matched as text rather than as an identifier.
`format(path: string, source: string)`	—	That source laid out by Rune's own formatter; the source unchanged when it will not parse.
`functions(path: string)`	—	The public functions a script file declares, with their argument names.
`hover(path: string, source: string, line: int, column: int)`	—	What is under that caret, as `#{ title, detail, doc }`, or `()` when it is nothing the engine knows.
`references(path: string, source: string, name: string)`	—	Every place that name appears as a whole word across the files this one's `mod` declarations reach, as `[#{ file, line, column, url }]`.
`rename(path: string, source: string, from: string, to: string)`	—	Every file a rename would rewrite, as `[#{ file, source }]`; nothing is written, so a caller can show the list first.
`replace(path: string, source: string, from: string, to: string)`	—	Every file a find and replace would rewrite, as `[#{ file, source }]`; nothing is written, so a caller can show the list first.
`require(path: string)`	—	Load another script file as a module, compiled once and shared by every caller afterwards.
`shared(f: fn)`	—	Wrap a script function so another script's code can call it, with whatever arguments the caller brings.
`signature(path: string, source: string, line: int, column: int)`	—	The call the caret is inside, as `#{ title, detail, doc, active }`, where `active` is the argument being typed.
`store(key: string, value: any)`	—	Keep any value under a key for as long as the app runs, held by reference: state no node owns, like a class's static variable.
`stored(key: string)`	—	What `store` kept under a key, the same value rather than a copy; nil when nothing was.
`symbols(path: string, source: string)`	—	What that file declares, as `[#{ name, kind, detail, line, column }]`: its public functions and its `exports()` properties.
