h2cppx(vim-port): Parse C++ header files and generate C++ implementation code

This is a Python 3 port of: https://github.com/vim-scripts/h2cppx

Purpose: Parse the C++ header file and generate C++ implementation code

Required: Python 3.x

Author: xiaok

Python modules required:

cheetah3 yaml

Already included modules:

pyvisitor CppHeaderParser (modified) 

Installation

Make sure you have "yaml" and "cheetah3" modules installed:

pip install cheetah3 yaml

Use your favorite plugin manager to install the plugin:

Example fo vim-plug:

`Plug 'coldspark29/h2cppx-vim'`

Mapping example:

nmap <F3>  :H2cppx<ESC>
nmap <F4>  :H2cppxLine<ESC>
nmap <F3>p :CpH2cppx<ESC>
nmap <F4>p :CpH2cppxLine<ESC>
nmap <F5>  :H2cppxAuto<ESC>

Configuration

If the plugin can't find the python path in your computer, you need set g:python_path in the .vimrc file:

let g:h2cppx_python_path = '/usr/bin/python'

You can specify the file name extension as follows: (default is .cpp)

let g:h2cppx_postfix = 'cxx'

Five code-generation template files are provided by default. You can configure them in .vimrc by specifiying templates 0-4: (default is template1)

let g:h2cppx_template = 'template4' 

If needed, you can refer to the default template and write your own template files. Use the absolute path to configure it:

let g:h2cppx_template = '/home/xxx/.../xxx'

Finally, you can add a configuration file .h2cppx_conf in your project directory to help the plugin search for a .cpp file. Otherwise the plugin will use .cpp file in your header file directory. The configuration file might look like:

/home/test/temp/src
src1
src2

See the project_sample directory.

Usage

The plugin function description:

• :H2cppx
  Parse the C++ header file and generate .cpp file with the same name

• :CpH2cppx
  Store file content in the register instead of creating a file. Paste with "p".

• :H2cppxLine
  Generate C++ code of the line under the cursor, and append it at the end of the .cpp file.

• :CpH2cppxLine
  Generate C++ code of the line under the cursor and store it in a register. Paste with "p".

• :H2cppxAuto (Recommended)
  Auto Contrast header and implementation files. Find function declarations in the header file and append the newly added to the implementation file. If the file does not exist a new file is created!
