Inspect `auto` with Power of Clang
==================================

This plugin inspects `auto` declarations in your Vim.  You can know the type of `auto` declarations easily.

## Installation

This plugin depends on [libclang-vim](https://github.com/rhysd/libclang-vim).  This is a wrapper of libclang.  Please see [README](https://github.com/rhysd/libclang-vim/blob/master/README.md) to install it.

After installing libclang-vim, you can install this plugin like other plugins.

I recommend to use modern Vim plugin managers like [vundle](https://github.com/gmarik/vundle) or [neobundle.vim](https://github.com/Shougo/neobundle.vim).

Below neobundle.vim setting has done all successfully.

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

NeoBundleLazy 'rhysd/clang-type-inspector.vim', {
            \ 'depends' : 'rhysd/libclang-vim',
            \ 'autoload' : {
            \       'filetypes' : 'cpp'
            \   }
            \ }
```

## Usage

### Mapping

You can set `<Plug>(clang-inspect-type-at-cursor)` to your favorite mapping.  For example, below setting maps it to `<C-t>`.

```vim
augroup clang-inspect-type-mapping
    autocmd!
    autocmd FileType cpp nmap <C-t> <Plug>(clang-inspect-type-at-cursor)
augroup END
```

### Automatic Inspection

As default, when the cursor is on auto-declaration, type of the declaration is displayed.
If you want to disable this feature, set `g:clang_type_inspector#automatic_inspection` to `0`.

### Balloon (gVim only)

gVim can show balloon which displays the information where the mouse is pointing(See `:help balloon-eval`).  This plugin displays the type using balloon.  When you point the specific location of buffer with the mouse pointer, a balloon would be launched and show the type.  This feature is enabled as default. If you want to disable this feature, set `g:clang_type_inspector#disable_balloon` to `1`.

### Function

You can get the type with below function.

```
clang_type_inspector#inspect_type_at({line}, {col}, {option})
```

`{line}` and `{col}` is line and column of the source.

`{option}` is a dictionary.  If `{option}` has `file` key,  its value specifies the file name of source.  If `{option}` has `bufnr` key, its value specifies the buffer number of source.  If both `file` and `bufnr` are not specified, the current buffer is used as the source to inspect.  If `{option}` has `compiler_args` key, its string value would be passed to a compiler as a compiler argument.

## Canonical Type

If you want to know only a canonical type, set `g:clang_type_inspector#canonical_type` to `2`.  If you want to know only a non-canonical type, set `g:clang_type_inspector#canonical_type` to `0`.  As default, this plugin shows both canonical type and non-canonical type when they are different.

## No Too Long Type Bothers You

The type names which are too long to be shown in one-line (e.g. expression templates) would be shortened to output in one-line.  This is because multiline output to command line blocks vimmer's editting.  If you still want to whole long types in multiline output, set `g:clang_type_inspector#shorten_too_long_type_name` to `0`.
