thanks a lot for this PR!
Can you explain this syntax and how it works real quick for me?

Hi, of course.
"-d:*: :(${all_contexts})"
- -d -> The kubectx subcommand.
- '*' -> This describes multiple arguments. All contexts matching the pattern (
*, all) will be completed. - ' ' -> An empty description.
- (${all_contexts}) -> An action describing all words to be completed.
"(- *): :(- ${all_contexts})"
- (- *) -> If one of the contexts has already been selected (and is on the command line), it will not complete other options anymore. (i.e this will avoid
kubectx ctx1 ctx2) - ' ' -> An empty description.
- (- ${all_contexts}) -> An action describing all words to be completed, including the current one (
-).

Why does the description have a space character to be “empty”?

AFAIK the spec needs this space to know what optspec I'm using (optname:*pattern:message:action and no optname:message:action). I can add a description for them if you want. WDYT?

Another relevant point is I'm not completing with all the current subcommands like -d, -h and -c. The subcommand -d will only be completed if the user enters the -d option (typing).

Yeah, makes sense. Thanks.
I might find you again when there's an issue with this file. 😄
