Server is different version than REPLSmuggler.jl

[Elphikaus]

Hi,

I have REPLSmuggler.jl v0.5.1
nvim: 1.10.2
julia: 1.11.2
Ubuntu 22

I am trying out this package, I am new to neovim and so, plugins are not a confident area for my neovim + julia usage.

I am getting an error that does not let me send code to the REPL, especially when I try <leader>cs.

Here is what I have looked at:

In protocols.lua there is

M.PROTOCOL_VERSION = vim.version.parse("0.5.x")

on line 4.

On line 93

    if vim.version.gt(M.PROTOCOL_VERSION, serverprotocolversion) then
        log.fatal(
            "The server uses version: "
                .. M.format_version(serverprotocolversion)
                .. " and we expect: "
                .. M.format_version(M.PROTOCOL_VERSION)
                .. ". Consider upgrading REPLSmuggler.jl."
        )
        success = false

I run

using REPLSmuggler
smuggle()

then I get

[ Info: Ahoy, now smuggling from socket /run/user/1000/julia/replsmuggler/illicit_covert_transport.
Task (runnable, started) @0x00007878028ab530

If I do showsmuggler()

/run/user/1000/julia/replsmuggler/illicit_covert_transport

But in my other winder in nvim if is select text in visual mode and run <leader>cs I get this error:

[smuggler] (10/19:37)
.../share/nvim/lazy/nvim-smuggler/lua/smuggler/protocol.lua:93
The server uses version: 0.4.0 and we expect: 0.5.0. Consider upgrading REPLSmuggler.jl

I am allowed to press enter and I see on the REPL side:

┌ Info: New client connected
└   session = Session{Base.PipeEndpoint}()


┌ Info: REPL client exited
└   session = Session{Base.PipeEndpoint}()

Can you assist in my debugging of this problem.

Hi! The error you are getting is due to a mismatch in the versions of the protocol that the Julia library and the NeoVim plugin use. If I had to guess I'd say you installed the latest development version of the NeoVim plugin (probably cloning the repository from your package manager?), and installed REPLSmuggler.jl via the standard ]add REPLSmuggler in the Julia REPL. I only guaranty compatibility between versions that are tagged. However, the two latest dev versions are also compatible. If you want to use the lastest versions (with the newest features), then you need to do ]add REPLSmuggler#main.

I should release the new versions at some point if you prefer to pin versions, but I am a bit short on time lately.

Hope this helps!

Hi,

Thanks.

I used the Lazy way

return {
  "klafyvel/nvim-smuggler",
  config=true,
  dependencies = { "nvim-neotest/nvim-nio" },
}

Then did :Lazy update

I will try the ]add REPLSmuggler#main.

I did! That works.

Though <leader>cs is only doing the last line on the cursor is on.

I did! That works.

Amazing!

Though <leader>cs is only doing the last line on the cursor is on.

That's the intended behavior, the default mapping of <leader>cs is to the :Smuggle command (see :help :Smuggle). If you want to send a block of code instead of a single line you have several options:

1. You want to end the next 10 lines: :10Smuggle
2. You want to send every lines to the end of the file :.,$SmuggleRange
3. You want to send the visual selection, use :SmuggleVisual in visual mode
4. You want to send text-objects (if you don't know what that is, you definitley want to have a look, that's one of the best features of (neo)vim!), you can for example send a paragraph using gcsap.

(I am not happy with the current high number of different commands. I hope to reduce everything to only one :Smuggle command for v1.0 of the plugin)

For the <leader>cs in visual mode, when I have selected multiple lines, you mean that I will only send the last line?

Is this what you mean from here in smuggler.txt:
smuggle_range = "<leader>cs", -- For SmuggleRange in visual mode.

I do not know about the text-objects. Is that something at tree-sitter to learn about?

Hm, I'll need to try it, I usually call the command explicitly in visual mode using auto-completion, typing :Sm<tab>V<tab> you'll get :'<,'>SmuggleVisual, which sends the visual selection.

No, that's a native vim feature, although it is possible to use tree-sitter to create even more powerful text objects (for example I have defined a text-object that corresponds to the content of a code cell in markdown, which I then use to send code with REPLSmuggler). You can learn about text-objects by reading :h text-objects. This is actually part of :h motions.txt, which I recommend reading, it is also a good entry point to get the idea behind some key vim concepts (see also this legendary SO post). For example using marks can be very powerful when working on a file: say you know you will re-run often the file starting from the same point (because it resets your plot library or reload data, etc...) but you are actually tweaking some lines towards the end of the file. You can leave a mark a by typing ma at the former, then go to the latter, do your editing, then jump back to mark a by typing 'a then gcsG to send all lines from current position to the end of the file and finally '' to go back to where you were editing.

you can add
xnoremap <leader>cs :SmuggleVisual<CR>
which will send the visual selection.

one annoying problem of sending through SmuggleVisual is
the cursor is at the start of the selection after its called.

i have this instead in my lua config which restores the cursor.

function Julia_send_region()
    local loc = vim.api.nvim_win_get_cursor(0)
    local keys = ":SmuggleVisual<CR>"
    local mode = "x"
    vim.api.nvim_feedkeys(vim.api.nvim_replace_termcodes(keys, true, true, true), mode, true)
    vim.api.nvim_win_set_cursor(0, loc)
end

vim.api.nvim_create_autocmd("FileType", {
    pattern = { "julia" },
    callback = function()
        vim.keymap.set(
            "x", "<Leader>s",
            Julia_send_region
        )
    end
}
)

this will restore the cursor position
