Close but not close enough. For example: in VSCode you can select/hover over any expression and it’ll tell you the computed TypeScript type. None of the current language server tools for Vim (eg ALE) give you that information [0]. Why would I live without this useful feature just to use Vim? I love Vim, but I love knowing the type the TS compiler thinks an expression is even more, especially when good enough Vim emulation is available.

:ALEHover
- dmitryminkovsky 6y ago
  Can that issue be closed? I can visually select an arbitrary expression and :ALEHover?

All LSP clients for vim will give you that; it is whatever command calls `hover` on the language server (e.g. ALEHover for ALE or LanguageClient_textDocument_hover for LanguageClient-neovim). Obviously you should bind these to some convenient command like <leader>t.

  Do you know if it’s possible in vim to show hover for an arbitrary selection? A visual selection?

    Like many things in vim it depends on whether you wish to write it ;) You can define your own popup(:h bexpr) however you feel, including per-filetype or buffer. Instead of simply operating on the variables it defines to you can also work upon the selection by querying the register(:h quotestar) instead. As an example, I like displaying wordnet¹ popups when writing prose. Occasionally, I'll also dump diction² output in to a popup too. However, I do think that using messages(:h :messages) might make more sense for selection info in general. That way you can select a text, call a map to display information, and still easily recall that data when you're in another place via :messages at a later time. Depends entirely on your use case, and once again how interested in writing the functionality you are. ¹ http://wordnet.princeton.edu/ http://wordnet.princeton.edu/ ² http://www.gnu.org/software/diction/diction.html http://www.gnu.org/software/diction/diction.html

i use coc-nvim with tsserver and i'm pretty sure it supports this https://github.com/neoclide/coc-tsserver https://github.com/neoclide/coc-tsserver
