Add newline to printVersion

[LDprg]

Hi,
I did notice that the default version display is missing a newline. This can prevent some visual bugs in the terminal.

Summary of Changes

Hello @LDprg, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a small but impactful change to the version display mechanism. It ensures that the output of the version information always includes a trailing newline character. This seemingly minor adjustment is crucial for maintaining clean and predictable terminal output, thereby preventing visual glitches and improving the overall user experience when interacting with the command-line interface.

Highlights

• Version Output Formatting: A newline character has been added to the printVersion function's output to ensure proper terminal display.
• Visual Bug Prevention: This change aims to prevent potential visual bugs in the terminal that could occur when the version string is displayed without a trailing newline.

Code Review

This pull request correctly adds a missing newline character to the version output, which will fix potential display issues in terminals. My review includes a suggestion to refactor the printVersion function to improve its testability and maintain consistency with other parts of the code base.

[gemini-code-assist]

This correctly adds the newline. However, for better testability and consistency with printHelp, consider refactoring printVersion to accept a writer: *Writer argument. This would allow you to write unit tests for it using an in-memory writer, just as it's done for printHelp.

With such a change, the implementation could also be slightly simplified:

pub fn printVersion(
    self: MessageHelper,
    writer: *Writer,
) !void {
    const version_str = self.version orelse "Unknown";
    try writer.print("{s}\n", .{version_str});
    try writer.flush();
}

This would require updating the call site at line 667 to create and pass a writer, similar to how printHelp is called.

Code Review

This pull request aims to add a newline to the version output, which is a good improvement for terminal display. The refactoring to use orelse is also a nice touch for conciseness. However, the current implementation introduces a compilation error by calling print on std.fs.File.Writer directly, instead of on its interface field. I've left a comment with a suggested fix.

[gemini-code-assist]

The writer variable is of type std.fs.File.Writer, which does not have a print method. The print method is available on its interface field, which is a std.io.Writer. This change will cause a compilation error.

You should call print on writer.interface, similar to how it's used for flush on the next line.

        try writer.interface.print("{s}\n", .{version_str});
