[Feature Request] Allow char ranges for :FnlBuffer

[alexmozaidze]

Selecting a small portion of code for evaluation is a very often thing I do, but Tangerine's default keymaps don't allow char-wise evaluation, it simply expands to the whole line the selection touched.

I propose removing line ranges from :FnlBuffer and adding a check for whether the command was ran from Visual mode.

I made a hacky alternative to the default mapping you could use, though, it's not robust:

(lambda get-selection-range []
  (let [selection-start (vim.fn.getpos "v")
        selection-end (vim.fn.getpos ".")
        selected-text (vim.fn.getregion selection-start selection-end {:type (vim.fn.mode)})
        selected-text (table.concat selected-text "\n")]
    selected-text))

(map! [x] "gE" (λ []
                 (let [tangerine (require :tangerine/api)]
                   (tangerine.eval.string (get-selection-range)))))
