Emacs LSP HLS Wingman: why no choice about hole filling?

[tomjaguarpaw]

In Emacs lsp mode with HLS/Wingman, I can navigate to the typed hole below, hit C-c / and get the context menu. I am offered "Wingman: Attempt to fill hole", but it unilaterally fills it with a! Why doesn't it ask me if I want a or b? dante, by contrast, does ask me.

foo :: Int -> Int -> Int
foo a b = _

Side note: I think C-c / is a specific key combination I have configured myself. For others it may be different.

(global-set-key [(control ?c) ?/]
               'lsp-execute-code-action)

Hmm, the lsp protocol defines some fixed ways for the interaction between the client (editor) and the server. So not always is possible introduce the input of the user in the required step. Separate the editor from the ide has some disavantadges.

Not sure if in this case it would be possible though.

Interesting, thanks! Gives me something to investigate.
