C++ Helper Snippets Using Treesitter

nt-cpp-tools

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

Features

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

Install

Using paq

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

Setup

Append the following config to the nvim-treesitter config

nt_cpp_tools = {
    enable = true,
    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'nvim-treesitter.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

1. TSCppDefineClassFunc

2. TSCppMakeConcreteClass

3. TSCppRuleOf3
