Language support for Heddle.heddle templates: typed member
completion, live diagnostics at template positions, hover types, semantic coloring, and
go-to-definition across imports.
Everything is a projection of the real Heddle compiler pipeline, so completion and diagnostics are
correct rather than heuristic. The extension bundles the heddle-lsp language server for its
platform; no separate server install is needed. TextMate coloring keeps working even when the
server is unavailable.
Requirements
The bundled server runs on the .NET 10 runtime. Install it from
dot.net if it is not already present.
Configuration
A .heddle-lsp.json at the workspace root replaces the settings below entirely, so it is the
editor-agnostic carrier for teams. Without it, these settings apply:
Setting
Purpose
heddle.model.assemblies
Model, extension and function assembly paths for typed completion.
heddle.workspace.rootPath
Template root for @<< import and @partial resolution.
heddle.compile.outputProfile
html (default) or text.
heddle.compile.expressionMode
native (default), memberPathsOnly or fullCSharp.
heddle.compile.fileNamePostfix
Template file name postfix.
heddle.compile.trimDirectiveLines
Whether whole-line directives swallow their line.
heddle.compile.maxRecursionCount
Compile-time recursion bound.
heddle.server.path
Explicit path to a heddle-lsp server, overriding the bundled one.
heddle.trace.server
LSP trace level: off, messages or verbose.
Command: Heddle: Restart Language Server.

configuration keys the language server accepts.
