📝 WalkthroughWalkthroughAdded a new Clap.Net Roslyn source generator example with a console demo, generated parser documentation, CodeTour, video workflow, and catalog entries. Repository counts and update dates now report 282 examples. ChangesClap.Net example
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔴 Critical · up to This PR adds the Clap.Net example and its documentation, but the current version contains an invalid workflow, non-portable paths, and sample code that does not match the generated API or handle invalid input correctly. These issues can prevent the example from running or being reused reliably, so they should be fixed before merge. Sequence Diagram(s)sequenceDiagram

In `@v2/book/examples/Clap.Net.html`:
- Line 23: Add concise, descriptive alt text to each img element in
Clap.Net.html, including the screenshots at the referenced locations, so screen
readers can identify the example code shown; keep the existing image sources and
dimensions unchanged.
In `@v2/book/list.html`:
- Line 20: Update the heading text in the HTML so the greater-than character is
represented as the escaped entity > rather than >, resolving the
HTMLHint warning while preserving the displayed text.
In `@v2/rscg_examples_site/docs/indexRSCG.md`:
- Line 23: Remove the trailing space from the link text in the Clap.Net entry,
changing the link label to end immediately after “Curtis” while preserving the
URL and surrounding table content.
In `@v2/rscg_examples_site/docs/RSCG-Examples/Clap.Net.md`:
- Around line 84-98: Remove the escaping backslashes before opening and closing
braces in all C# fenced code blocks in the Clap.Net documentation page,
including the GreetCommand example, so copied snippets contain valid C# syntax.
- Around line 553-555: Correct the generated-files documentation under
“Generated Files” to reference the actual output property,
BaseIntermediateOutputPath, when describing the GX directory; do not use
BaseIntermediatePath.
- Line 508: Replace the machine-specific TabItem.value paths in the Clap.Net
documentation with stable identifiers such as program, cmd-for-sum, and
generated-parser, while preserving the existing labels and tab content.
- Around line 58-80: Correct the Markdown heading hierarchy in the Clap.Net
documentation: replace the over-deep Why Clap.Net, Quick Start, Installation,
and Basic Example headings with sequential levels under the existing Clap.Net
section, never exceeding six hash characters. Preserve the heading text and
content.
In `@v2/rscg_examples/Clap.Net/nuget.txt`:
- Line 1: Replace the placeholder text in the Package Description entry with the
actual Clap.Net package description, ensuring generated catalog pages no longer
publish “Package Description.”
In `@v2/rscg_examples/Clap.Net/readme.txt`:
- Around line 408-412: Fix the broken CLAUDE.md and LICENSE references in the
README section by either adding those files at the referenced locations or
replacing both links with valid existing URLs; ensure neither link points to a
nonexistent resource.
- Around line 210-223: Update both v2/rscg_examples/Clap.Net/readme.txt lines
210-223 and v2/rscg_examples_site/docs/RSCG-Examples/Clap.Net.md lines 261-275
to use the generated parse-result members IsError, Error, IsSuccess, and Command
instead of IsT3, AsT3, and AsT0 in both examples.
In `@v2/rscg_examples/Clap.Net/src/ConsoleDemo/CmdForSum.cs`:
- Around line 9-13: Update the Arg declarations for x and y in CmdForSum so
integer arguments using ArgAction.Set cannot be parsed as valueless compound
short options such as -fs; remove their Short aliases or update the generator’s
ArgAction.Set handling to require integer values, while preserving the long
options and existing argument behavior.
In `@v2/rscg_examples/Clap.Net/src/ConsoleDemo/Program.cs`:
- Around line 4-7: Update Program’s command parsing flow to use
CmdForSum.TryParse(args) instead of CmdForSum.Parse(args); handle help and
version results, print parse errors, and return a non-zero exit code for invalid
input. Catch FormatException from integer conversion until those failures are
represented as parse results, while preserving successful execution through
cmd.MySum().
In `@v2/rscg_examples/Clap.Net/video.json`:
- Around line 18-24: Replace the hard-coded D:\gth\RSCG_Examples\v2 prefixes in
the video workflow’s exec, stepvscode, and project-reference arguments with
repository-relative paths or the workflow’s configurable workspace-root
variable, preserving the existing solution, workspace, and ConsoleDemo.csproj
targets.
- Line 29: Update the tour step’s arg in the tour configuration to reference the
directory containing Clap.Net.tour: use .tours/ from the v2 workspace, or
v2/.tours/ when resolved from the repository root, instead of src/.tours/.
- Around line 35-38: Fix the workflow JSON by removing the unsupported SpeakTest
property from the browser step and deleting the trailing comma after the final
waitseconds array item, leaving valid JSON.

| ###### Why Clap.Net? | ||
|
|
||
| **Zero Runtime Overhead** | ||
| Source generators produce parsing code at compile time. No reflection, no performance penalties—just pure, optimized C# code. | ||
|
|
||
| **Type Safety First** | ||
| Your command-line interface is defined using strongly-typed classes and properties. Catch errors at compile time, not runtime. | ||
|
|
||
| **Batteries Included** | ||
| Automatic help generation, version handling, environment variable fallback, subcommands, and rich argument types—all out of the box. | ||
|
|
||
| **Developer Friendly** | ||
| Leverage C# language features like `required` properties, nullable types, and pattern matching. Your CLI definition is just normal C# code with a few attributes. | ||
|
|
||
| ###### Quick Start | ||
|
|
||
| ######### Installation | ||
|
|
||
| ```bash | ||
| dotnet add package Clap.Net | ||
| ``` | ||

Fix the embedded README heading hierarchy.
The page jumps from ### Clap.Net to ###### Why Clap.Net? and then uses more than six hash characters for later headings. Use sequential heading levels, with a maximum of six, so the document outline and table of contents remain usable.

Remove backslashes from C# braces in fenced code blocks.
The rendered snippets contain \{ and \} instead of { and }. Readers who copy these snippets receive invalid C# code. Apply this correction to all C# code blocks in the page.

Clap.Net 0.2.39 CompoundFlag integer Arg Short Long source
💡 Result:
The library Clap.Net (version 0.2.39) is a C# source generator for command-line argument parsing [1][2]. Based on the official repository documentation, Clap.Net does not contain a feature or class named "CompoundFlag" [1][3]. The term "CompoundFlag" appears to be associated with the gem5 simulation project's debugging infrastructure, which is unrelated to the Clap.Net CLI parsing library [4][5]. In Clap.Net, arguments are defined using the [Arg] attribute, which supports the following properties for configuration [1][3]: Short: A char used for the short flag version (e.g., 'v' for -v) [1][3]. Long: A string used for the long flag version (e.g., "verbose" for --verbose) [1][3]. Help: A string providing a description for the argument [1][3]. Action: Defines how values are handled (e.g., ArgAction.Append for collections) [1][6][3]. For arguments requiring integer or other non-string types, Clap.Net supports type conversion via automatic parsing or custom parsers defined with the ValueParser attribute (which requires a static Parse(string) method) [1][3]. Multi-value arguments in Clap.Net are handled as follows [6][7]: - For named array arguments (e.g., string[] or int[]), each flag invocation typically captures one value; to collect multiple, the flag must be repeated [6][7]. - Positional array arguments are "greedy" and consume all remaining positional values provided on the command line [6][7]. - Collections using ArgAction.Append allow for building lists via repeated flag usage [6][7].

Avoid compound short options for integer arguments. Clap.Net 0.2.39 parses -fs as x = 1 and y = 1 without integer values. Remove the short options or fix the generator to require values for ArgAction.Set.

Return a non-zero exit code for invalid input.
CmdForSum.Parse(args) exits with code 0 for parse errors and throws FormatException for invalid integers. Use CmdForSum.TryParse(args), handle help and version results, print parse errors, and return a non-zero code. Catch FormatException until conversion failures become parse results.

Remove machine-specific paths from the video workflow.
The workflow hard-codes D:\gth\RSCG_Examples\v2. Use repository-relative paths or a configurable workspace root so other contributors can replay the workflow.

Use the directory that contains Clap.Net.tour.
The new tour is stored in v2/.tours/Clap.Net.tour, but this step requests src/.tours/. From the v2 workspace, use .tours/, or use v2/.tours/ when resolving from the repository root.

Fix the invalid JSON before using this workflow.
SpeakTest=" " is not a valid JSON property. The final array item also has a trailing comma. Remove SpeakTest if it is not supported, and remove the final comma.
