From 30ff10159941e45a41743db74e0eb58740f63abd Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 25 May 2026 19:00:40 +0000 Subject: [PATCH 01/24] Add survey example demonstrating Terminal.Gui + Spectre.Console Ports Spectre.Console's Prompt example to Terminal.Gui.Cli as a TG/Spectre collaboration (spectre.console#2128): Terminal.Gui handles interaction, the host adds structured --json, --cat, OpenCLI, and an agent guide, and Spectre.Console renders the resulting profile card (Panel, Table, BarChart). To emit a structured result value under source-generated JSON (constitution C4), add CliHostOptions.ResultJsonResolver plus a JsonEnvelope.ToJson overload that combines a consumer JsonSerializerContext with the built-in context via JsonTypeInfoResolver.Combine. This keeps serialization reflection-free and AOT-compatible; update specs/library-spec.md accordingly. The in-TUI Spectre rendering (SpectreView) will be wired once the Terminal.Gui.Interop.Spectre bridge package is published. https://claude.ai/code/session_014gpZxbbFxi3SNNqqHPc4Wi --- Terminal.Gui.Cli.slnx | 1 + examples/survey/CardCommand.cs | 133 +++++++++++++ examples/survey/ProfileInput.cs | 74 +++++++ examples/survey/Program.cs | 3 + examples/survey/README.md | 56 ++++++ examples/survey/Resources/Help/card.md | 24 +++ examples/survey/Resources/Help/help.md | 25 +++ examples/survey/Resources/Help/survey.md | 29 +++ examples/survey/Resources/agent-guide.md | 56 ++++++ examples/survey/SpectreProfile.cs | 68 +++++++ examples/survey/SurveyAnswers.cs | 18 ++ examples/survey/SurveyApp.cs | 29 +++ examples/survey/SurveyCommand.cs | 183 ++++++++++++++++++ examples/survey/SurveyJsonContext.cs | 14 ++ .../survey/Terminal.Gui.Cli.Survey.csproj | 25 +++ specs/library-spec.md | 16 ++ src/Terminal.Gui.Cli/CliHost.cs | 3 +- src/Terminal.Gui.Cli/CliHostOptions.cs | 8 + src/Terminal.Gui.Cli/JsonEnvelope.cs | 23 ++- src/Terminal.Gui.Cli/ResultWriter.cs | 6 +- .../SurveyExampleTests.cs | 119 ++++++++++++ .../Terminal.Gui.Cli.IntegrationTests.csproj | 1 + tests/Terminal.Gui.Cli.Tests/OutputTests.cs | 23 +++ 23 files changed, 933 insertions(+), 4 deletions(-) create mode 100644 examples/survey/CardCommand.cs create mode 100644 examples/survey/ProfileInput.cs create mode 100644 examples/survey/Program.cs create mode 100644 examples/survey/README.md create mode 100644 examples/survey/Resources/Help/card.md create mode 100644 examples/survey/Resources/Help/help.md create mode 100644 examples/survey/Resources/Help/survey.md create mode 100644 examples/survey/Resources/agent-guide.md create mode 100644 examples/survey/SpectreProfile.cs create mode 100644 examples/survey/SurveyAnswers.cs create mode 100644 examples/survey/SurveyApp.cs create mode 100644 examples/survey/SurveyCommand.cs create mode 100644 examples/survey/SurveyJsonContext.cs create mode 100644 examples/survey/Terminal.Gui.Cli.Survey.csproj create mode 100644 tests/Terminal.Gui.Cli.IntegrationTests/SurveyExampleTests.cs diff --git a/Terminal.Gui.Cli.slnx b/Terminal.Gui.Cli.slnx index f78cb7c..63b74b2 100644 --- a/Terminal.Gui.Cli.slnx +++ b/Terminal.Gui.Cli.slnx @@ -17,6 +17,7 @@ + diff --git a/examples/survey/CardCommand.cs b/examples/survey/CardCommand.cs new file mode 100644 index 0000000..1874b7f --- /dev/null +++ b/examples/survey/CardCommand.cs @@ -0,0 +1,133 @@ +using System.Text; +using Terminal.Gui.App; +using Terminal.Gui.Input; +using Terminal.Gui.ViewBase; +using Terminal.Gui.Views; + +namespace Terminal.Gui.Cli.Survey; + +/// +/// A viewer command that renders a profile as a rich Spectre.Console card.
