nt-cpp-tools

Experimental treesitter based neovim plugin to create intelligent implementations for C++

Features

Out-of class member function implementation
Concrete class implement from Abstract class or Interface
Add missing functions to obey Rule of 3
Add missing functions to obey Rule of 5

Install

Using paq

require "paq" {
    "nvim-treesitter/nvim-treesitter",
    "Badhi/nvim-treesitter-cpp-tools",
}

Using packer.nvim

use {
    requires = { "nvim-treesitter/nvim-treesitter" },
    "Badhi/nvim-treesitter-cpp-tools",
}

Using lazy.nvim

{
    "Badhi/nvim-treesitter-cpp-tools",
    dependencies = { "nvim-treesitter/nvim-treesitter" },
    -- Optional: Configuration
    opts = function()
        local options = {
            preview = {
                quit = "q", -- optional keymapping for quit preview
                accept = "<tab>", -- optional keymapping for accept preview
            },
            header_extension = "h", -- optional
            source_extension = "cpp", -- optional
            custom_define_class_function_commands = { -- optional
                TSCppImplWrite = {
                    output_handle = require("nt-cpp-tools.output_handlers").get_add_to_cpp(),
                },
                --[[
                <your impl function custom command name> = {
                    output_handle = function (str, context) 
                        -- string contains the class implementation
                        -- do whatever you want to do with it
                    end
                }
                ]]
            },
        }
        return options
    end,
    -- End configuration
    config = true,
}

Setup

For lazy.nvim, see Install

Add the following config to your init script

Note: The config for this plugin, included in the treesitter.config is now moved to an independent config. Please make required changes

require 'nt-cpp-tools'.setup({
    preview = {
        quit = 'q', -- optional keymapping for quit preview
        accept = '<tab>' -- optional keymapping for accept preview
    },
    header_extension = 'h', -- optional
    source_extension = 'cxx', -- optional
    custom_define_class_function_commands = { -- optional
        TSCppImplWrite = {
            output_handle = require'nt-cpp-tools.output_handlers'.get_add_to_cpp()
        }
        --[[
        <your impl function custom command name> = {
            output_handle = function (str, context) 
                -- string contains the class implementation
                -- do whatever you want to do with it
            end
        }
        ]]
    }
})

Usage

Select the range of the class using visual mode
Use below commands

Command	Feature
`TSCppDefineClassFunc`	Implement out of class member functions subset of functions can be implemented by selecting required function declarations using visual mode or simply keeping the cursor on the function declaration before calling the command Supported special features 1. Templates (with default args) 2. Function arguments with default values 3. Nested classes (check test_cases for tested examples)
`TSCppMakeConcreteClass`	Create a concrete class implementing all the pure virtual functions
`TSCppRuleOf3`	Adds the missing function declarations to the class to obey the Rule of 3 (if eligible)
`TSCppRuleOf5`	Adds the missing function declarations to the class to obey the Rule of 5 (if eligible)

Example

TSCppDefineClassFunc

TSCppMakeConcreteClass

TSCppRuleOf3
