Purpose

Turn language-server results into short text a model reads well: 1-based positions, workspace- relative paths, and one line per item.

Interface

Signatures

export fn hover(result: &Json.Json) -> Str
export fn locations(result: &Json.Json, shown: fn(Str) -> Str) -> Array[Location]
export fn locationLine(held: &Location) -> Str               // "path:line:character"
export fn completion(result: &Json.Json, limit: Int) -> Str
export fn signatureHelp(result: &Json.Json) -> Str
export fn codeActions(result: &Json.Json) -> Str
export fn workspaceEdit(result: &Json.Json, shown: fn(Str) -> Str) -> Str
export fn documentSymbols(result: &Json.Json) -> Str
export fn workspaceSymbols(result: &Json.Json, shown: fn(Str) -> Str) -> Str
export fn diagnostics(items: &Array[Json.Json]) -> Str

export type Location = { uri: Str, path: Str, line: Int, character: Int, endLine: Int }   // 1-based

Linkage

• Requires: Std.Json, [[src/PuduLangMcp/Utils/JsonAccess]].
• Consumed by: [[src/PuduLangMcp/App/Tools/Language]].

Algorithm

• hover: contents as markup (value), a plain string, or a list of either, joined by blank lines. null answers "No information at this position."
• locations: a Location, a list of them, or LocationLinks (targetUri, targetRange).
• completion: a list or a CompletionList.items; each label — detail, at most limit, then a count of the rest.
• signatureHelp: the active signature's label, its documentation, and the active parameter's label when the parameter label is a string or a [start, end] offset pair into the signature.
• codeActions: one line per action title, with its kind when present.
• workspaceEdit: changes (by URI) or documentChanges (textDocument.uri, edits), one line per edit: path:line:character-endLine:endCharacter → newText.
• documentSymbols: hierarchical DocumentSymbols (children indented) or SymbolInformations; kind name — detail (line N), kind named from the LSP symbol-kind table.
• diagnostics: line:character severity [code] message, severity named 1 error … 4 hint.

Negative Logic (Prohibited Paths)

• No raw JSON is shown to the model when a known shape can be rendered; an unknown shape falls back to its encoded JSON rather than being dropped.

Edge Cases

• An empty list renders as a sentence saying nothing was found.

Depth

DEPTH 0.55.

Grill Log

• Q: Show absolute paths? A: No; shown maps a URI to a workspace-relative path, the standard library's Std/... path, or <source> for inline code, so paths are short and do not leak the machine's layout.
