h2cppx(vim-port): parse the c++ header file and generate c++ implement code

Purpose: Parse the c++ header file and generate c++ implement code for vim plugin

Required: python 2.x

Author: xiaok

External module required: cheetah yaml(python package)

Third-party(the plugin already include): pyvisitor CppHeaderParser(modification)

Github-Link

Installation

Before start, make sure you have installed the python package "yaml", Then run below command:

cd ~/.vim/plugin
git clone 'https://github.com/xuqix/h2cppx.git
cd  h2cppx
git checkout vim-port

or you can use bundle to install it:

add Bundle 'xuqix/h2cppx' to ~/.vimrc and install it,then:

cd ~/.vim/bundle/h2cppx
git checkout vim-port

Now you can start using it.

After the installation is complete, You can map the key in .vimrc to quickly use the command.

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

Config

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

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

and you can specify the cppfile name extension like this: (default value is 'cpp')

let g:h2cppx_postfix = 'cxx'

five code-generate template file are provided by default,you can config it in '.vimrc' like this(template0-4,default is template1):

let g:h2cppx_template = 'template4' 

if needed,you can refer to the default template and write your own template files,and use absolute path config it :

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

Finally,you can add a configuration file .h2cppx_conf in your project directory to help plugin search for cppfile,otherwise the plugin will find cppfile 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 c++ header file and generate cpp file

• :CpH2cppx
  Like :H2cppx,but generat code in your clipboard, no file writed,you can use "p" to get it.

• :H2cppxLine
  Generate cpp code in the cursor line,and append to the end of the cpp file

• :CpH2cppxLine
  Like :H2cppxLine,but generat code in your clipboard, no file writed,you can use "p" to get it.

• :H2cppxAuto (Recommendation)
  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 to achieve a new file is created!

Example:

vim test.h
:H2cppx  
Now you can find new file "test.cpp" in your directory

vim test.h
:H2cppxLine
Now you can find defined in your file "test.cpp" from current line of cursor 

vim test.h
:CpH2cppx  
Like :H2cppx, but defined in your clipboard, no file writed, just use "p" to get it.

vim test.h
:CpH2cppxLine  
Like :H2cppxLine, but defined in your clipboard, no file is writed.

vim test.h
:H2cppxAuto 
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 to achieve 
a new file is created!
