- Renamed completer to be cobra_completer to match docs
- Added whitespace after each completion
- Implemented ShellCompDirectiveError, ShellCompDirectiveNoSpace, ShellCompDirectiveNoFileComp
- Disabled active help as it isn't supported by nushell
- Added nushell to the default completion command
Creating CompletionResult objects is not allowed in Powershell constrained mode, so return results as strings if constrained mode is enabled
Store results as PsCustomObjects instead of hashtables. This prevents Sort-Object from trying to convert the hashtable to a object, which is blocked in constrained mode.
PsCustomObjects are created using New-Object to work around https://github.com/PowerShell/PowerShell/issues/20767
* Fix --version help with CommandDisplayNameAnnotation
When setting Command.Version, a --version option is added. The help
message for the --version command did not consider the command display
name:
Flags:
-h, --help help for kubectl plugin
-v, --version version for kubectl-plugin
With this change the help test is consistent with other flags:
Flags:
-h, --help help for kubectl plugin
-v, --version version for kubectl plugin
* Make command DisplayName() public
This allows using the display name in templates or other code that want
to use the same value.
* Use display name in version template
The version template used `{{.Name}}` but for plugins you want to use
`{{.DisplayName}}` to be consistent with other help output.
With this change will show:
$ kubectl plugin --version
kubectl plugin version 1.0.0
* Improve site formatting
- Separate titles with blank lines
- Separate code blocks with blank lines
- Always use ``` blocks for examples
- Use console for console (bash syntax highlighting does work well with
example command output)
- Start console examples with $ (highlight command and output
differently and more friendly to other shells users)
* Unify indentation in example project structure
* Use single import line in the trivial examples
When we want to show a minimal example with single import it looks
cleaner and more minimal with a single line.
Fixing golangci-lint errors[1]:
Error: SA1019: "io/ioutil" has been deprecated since Go 1.19: As of
Go 1.16, the same functionality is now provided by package [io] or
package [os], and those implementations should be preferred in new
code. See the specific function documentation for details.

Deprecation comments should be at the start of a paragraph [1], and because
of that have a whitespace above them [2];
> To signal that an identifier should not be used, add a paragraph to its
> doc comment that begins with Deprecated: followed by some information
> about the deprecation (...)
With the whitespace missing, some tools, including pkg.go.dev [3] don't
detect it to be deprecated.

* Address golangci-lint linter deprecation warnings
1.59.0 outputs:
WARN [lintersdb] The name "gas" is deprecated. The linter has been renamed to: gosec.
WARN [lintersdb] The linter named "megacheck" is deprecated. It has been split into: gosimple, staticcheck, unused.
* Enable some more linters, address finding
* Remove fully inactivated linters
Currently golangci-lint fails with these errors:
ERRO [linters_context] golint: This linter is fully inactivated: it will not produce any reports.
ERRO [linters_context] interfacer: This linter is fully inactivated: it will not produce any reports.
ERRO [linters_context] maligned: This linter is fully inactivated: it will not produce any reports.
I could not find any docs explaining what "fully inactivated" mean, but
based this PR[1] it seems that these linters do nothing now. Removing
the linters fixes this issue without changing linting, as they did not
produce any report.
Looking in the linters docs[2] I did not find a replacement for
"interfacer" and "malinged" linters. "stylecheck" seems to be a
replacement for "golint", but we need to fix the code to enable it.

* Add stylecheck linter, replacement for golint
This revealed 2 capitalized error messages.

Add `Annotation` suffix to the private annotations to allow nicer code
using the constants.
For example one can use the current annotation names as a temporary
variable instead of unclear shortcut. Instead of this:
rag := flagsFromAnnotation(c, f, requiredAsGroup)
me := flagsFromAnnotation(c, f, mutuallyExclusive)
or := flagsFromAnnotation(c, f, oneRequired)
We can use now:
requiredAsGrop := flagsFromAnnotation(c, f, requiredAsGroupAnnotation)
mutuallyExclusive := flagsFromAnnotation(c, f, mutuallyExclusiveAnnotation)
oneRequired := flagsFromAnnotation(c, f, oneRequiredAnnotation)
Example taken from #2105.
When creating a plugin without sub commands, the help text included the
command name (kubectl-plugin) instead of the display name (kubectl plugin):
Usage:
kubectl-plugin [flags]
The issue is that the usage line for this case does not use the
command path but the raw `Use` string, and this case was not tested.
Add a test for this case and fix UsageLine() to replace the command name
with the display name.
Tested using https://github.com/nirs/kubernetes/tree/sample-cli-plugin-help
When using `CommandDisplayNameAnnotation` we want to use it instead of
the command name in `--help` message or in the default help command.
With current code we get the wrong text in the --help usage text:
Flags:
-h, --help help for kubectl-plugin
And in the long description of the default help command:
$ kubectl cobraplugin help -h
Help provides help for any command in the application.
Simply type kubectl-plugin help [path to command] for full details.
The issue was hidden since the test checked only the Usage line.
Fixed by extracting a displayName() function and use it when creating
FlagSet and when formatting the default help flag usage and the help
command long description.
Enhance the TestPlugin to check all the lines including the command
name.
