thanks @geoffharcourt, that’s great info – I figured there was no easy solution here or I would have heard of it. Keeping my fingers crossed for NeoVim. In the meantime, however, maybe you have an opinion on this question I just posted:
How can I display Rails “function hints” (method signature) snippets or expansions?
Same question, basically, but watered down to just method argument completion (i.e., just matching by name rather than having to know the class of an object and suggest methods based on that). Seems like this could be done pretty straightforwardly with snippets, at least for the standard Rails methods – what do you think? I’m still not aware of an existing solution.
