Make text objects for various C and C++ blocks with power of clang

This vim plugin makes text objects for various C and C++ blocks, function, class, namespace, expression, statement and so on.

Dependencies

• vim-textobj-user
• libclang-vim

If you use neobundle.vim, you can install this plugin easily as below.

NeoBundleLazy 'rhysd/libclang-vim', {
            \ 'build' : {
            \       'windows' : 'echo "Please build manually"',
            \       'mac' : 'make',
            \       'unix' : 'make',
            \   }
            \ }

NeoBundleLazy 'rhysd/vim-textobj-clang', {
            \ 'depends' : ['kana/vim-textobj-user', 'rhysd/libclang-vim'],
            \ 'autoload' : {
            \       'mappings' : [['xo', 'a;'], ['xo', 'i;']]
            \   }
            \ }

Simple operator-pending mappings i; and a;

Operator-pending mappings i; and a; are available. i; selects the element under cursor. a; selects the most inner definition under cursor.

For example, see below code.

int main()
{
    return 0;
}

When the cursor is placed at return, i; selects return 0; and a; selects whole main() function. This is very simple example. Clang can parse more complicated source files like Boost libraries.

More complicated operator-pending mappings

If you set g:textobj_clang_more_mappings to 1, many operator-pending mappings are defined. As a default, mappings in a below table are defined. You can control the number of the mappings with g:textobj_clang_mapping_kinds.

Mapping	Block
i;m	select the most inner definition
i;c	select class blocks
i;f	select function blocks
i;e	select an expression
i;s	select an statement
i;p	select an parameter and a template parameter
i;n	select a namespace
i;u	select an element under cursor
i;a	select expression, statement, function, class or namespace
