Adds Microsoft.CodeAnalysis.CSharp.Scripting (4.13.0). Scripts are
compiled as C# script fragments against a ScriptHost globals type
that mirrors what the runtime exposes (Parameters bag, CallShared,
CallScript) — Roslyn reads the signatures so those identifiers are
in scope for analysis without executing anything.
ScriptAnalysisService:
- Diagnose(code): Compilation.GetDiagnostics() projected to
Monaco-shaped DiagnosticMarker records (severity 8/4/2/1).
- Complete(code, line, col): dot-member lookup via SemanticModel
when the token at position is part of a MemberAccessExpression;
falls back to LookupSymbols at position for the general case.
Two endpoints exposed by the existing CentralUI endpoint pipeline,
both behind RequireDesign policy:
POST /api/script-analysis/diagnostics
POST /api/script-analysis/completions
monaco-init.js registers a csharp CompletionItemProvider with dot/
paren/quote trigger chars, plus a 500 ms debounced diagnostics pass
on every keystroke that pushes markers via setModelMarkers. Initial
pass fires on editor create so existing scripts surface errors right
away. Auth uses the existing cookie via credentials: same-origin.
Smoke-verified:
- Typing `DateTimeOffset.UtcNow` (no semicolon) shows the missing
semicolon squiggle in real time.
- Ctrl-Space at file scope returns the full type universe
(AccessViolationException, Action, Akka, AppDomain, ...).
Wave 2 of three. SCADA-specific extensions (declared param keys,
shared/sibling script names, forbidden-API diagnostic) follow.
Vendors Monaco 0.55.1 min/vs/ (~15 MB) at
wwwroot/lib/monaco/vs/. No CDN dependency; works on air-gapped
deployments. Loaded lazily on first script-edit via the AMD loader.
wwwroot/js/monaco-init.js exposes window.MonacoBlazor with
createEditor / setValue / getValue / setMarkers / dispose. Handles
loader bootstrap, DotNet round-trip on content change, and marker
sets for later diagnostic wiring.
Components/Shared/MonacoEditor.razor is a Blazor wrapper with
Value / ValueChanged / Language / Height / ReadOnly parameters and
IAsyncDisposable teardown. Bidirectional binding tracks
_lastSentValue to avoid push/pull loops.
Replaces the plain textareas in SharedScriptForm, TemplateEdit's
Add-Script form, and ApiMethodForm. Default height 320px ≈ the
previous rows=10. Build / tests / dialog flow unaffected.
Wave 1 of three. Roslyn-backed completions and SCADA-specific
extensions follow in subsequent commits.
