No horizontal scrolling for tag search | tags() and btags() can apply fzf option "--no-hscroll" in fzf_opts by default

[Lolligerhans]

By default, fzf scrolls horizontally to include the last matched section.

The default universal-ctags tags file contains the actual tag at the start of each line.

The default behavior allows scrolling the tag out of view. This happens especially when users deliberately fuzzygrep for contents that follow after the tag, like parts of a filename (".lua", "tests/", "doc/") or line ("function", "class", "local", "#define").

When scrolled horizontally, the helpfulness of the list of search results suffers dramatically.

Suggestion

Pass "--no-hscroll" to fzf for the tags and btags functions by default.

Workaround 1

I was able to achieve the intended behavior using fzf_opts explicitly. I am not sure if users are supposed to set fzf_opts.

vim.kemap.set({ "n" }, "<leader>e",

function()
  -- Works as intended
  require("fzf-lua").tags({ fzf_opts = { ["--no-hscroll"] = true } })
end,

{ remap = false, desc = "Example" })

Workaround 2 attempt

I tried setting a default behavior. This attempt in LazyVim did not work:

  {
    "ibhagwan/fzf-lua",
    opts = {
      defaults = {
        btags = {
          fzf_opts = {
            ["--no-hscroll"] = true, -- No effect?
          },
        },
        tags = {
          fzf_opts = {
            ["--no-hscroll"] = true, -- No effect?
          },
        },
      },
    },
  }

How would this be done correctly?

[ibhagwan]

Either apply to defaults (for all pickers or btags/tags outside outside of defaults to apply just to btags and tags:

  {
    "ibhagwan/fzf-lua",
    opts = {
      defaults = {
          fzf_opts = {
            ["--no-hscroll"] = true, -- No effect?
          },
        },
        -- or
        btags = { … },
    },
  }

I would also experiment with --wrap or press the default alt-/.

Thanks!

This solved my problem.
