A little (smart maybe) lsp signature helper for neovim.

Neovim Signature Help Plugin

This Neovim plugin provides a signature help feature for LSP (Language Server Protocol) clients. I can't tell much, just watch the showcases.

ScreenShots (WIP)

Features

• Signature Help: Displays function signatures and parameter information in a floating window with rich lsp support.
• Toggle Mode: Toggle signature help in normal mode, dock mode.
• Customizable: Highly customizable with options for icons, colors, and more.
• Integration: Integrates with nvim-treesitter for syntax highlighting.

Installation

Using lazy.nvim

Add the following to your init.lua and use main branch always:

require("lazy").setup({
  {
    "Dan7h3x/signup.nvim",
    branch = "main",
    opts = {
          -- Your configuration options here
    },
    config = function(_,opts)
      require("signup").setup(opts)
    end
  }
})

Using Vim-Plug

Add the following to your init.vim:

Plug "Dan7h3x/signup.nvim"

Then, in your init.lua:

lua << EOF
require('signup').setup({
  -- Your configuration options here
})
EOF

Configuration

The plugin comes with a default configuration, but you can customize it according to your preferences. Here are the available options:

{
    silent = true,
    icons = {
      parameter = "",
      method = "󰡱",
      documentation = "󱪙",
      type = "󰌗",
      default = "󰁔",
    },
    colors = {
      parameter = "#86e1fc",
      method = "#c099ff",
      documentation = "#4fd6be",
      default_value = "#a80888",
      type = "#f6c177",
    },
    active_parameter = true,   -- enable/disable active_parameter highlighting
    active_parameter_colors = {
      bg = "#86e1fc",
      fg = "#1a1a1a",
    },
    border = "rounded",
    dock_border = "rounded",
    winblend = 10,
    auto_close = true,
    trigger_chars = { "(", ",", ")" },
    max_height = 10,
    max_width = 40,
    floating_window_above_cur_line = true,
    debounce_time = 50,
    dock_toggle_key = "<Leader>sd",
    dock_mode = {
      enabled = false,
      position = "bottom",   -- "bottom", "top", or "middle"
      height = 4,            -- If > 1: fixed height in lines, if <= 1: percentage of window height (e.g., 0.3 = 30%)
      padding = 1,           -- Padding from window edges
      side = "right",        -- "right", "left", or "center"
      width_percentage = 40, -- Percentage of editor width (10-90%)
    },
  }
