" Features {{{1
"
" These options and commands enable some very useful features in Vim, that
" no user should have to live without.

" Set 'nocompatible' to ward off unexpected things that your distro might
" have made, as well as sanely reset options when re-sourcing .vimrc
" Vi互換モードをオフ(Vimの拡張機能を有効)
set nocompatible

" Attempt to determine the type of a file based on its name and possibly its
" contents.  Use this to allow intelligent auto-indenting for each filetype,
" and for plugins that are filetype specific.
" ファイル名と内容によってファイルタイプを判別し、ファイルタイププラグインを有効にする
filetype indent plugin on

" Enable syntax highlighting
" 色づけをオン
syntax on


"------------------------------------------------------------
" Must have options {{{1
"
" These are highly recommended options.
" 強く推奨するオプション

" One of the most important options to activate. Allows you to switch from an
" unsaved buffer without saving it first. Also allows you to keep an undo
" history for multiple files. Vim will complain if you try to quit without
" saving, and swap files will keep you safe if your computer crashes.
" バッファを保存しなくても他のバッファを表示できるようにする
set hidden

" Better command-line completion
" コマンドライン補完を便利に
set wildmenu

set history=5000 " 保存するコマンド履歴の数

" Show partial commands in the last line of the screen
" タイプ途中のコマンドを画面最下行に表示
set showcmd

" Highlight searches (use <C-L> to temporarily turn off highlighting; see the
" mapping of <C-L> below)
" 検索語を強調表示(<C-L>を押すと現在の強調表示を解除する)
set hlsearch

" ESCキー2度押しでハイライトの切り替え
nnoremap <silent><Esc><Esc> :<C-u>set nohlsearch!<CR>

" Modelines have historically been a source of security vulnerabilities.  As
" such, it may be a good idea to disable them and use the securemodelines
" script, <http://www.vim.org/scripts/script.php?script_id=1876>.
" 歴史的にモードラインはセキュリティ上の脆弱性になっていたので、
" オフにして代わりに上記のsecuremodelinesスクリプトを使うとよい。
" set nomodeline


"------------------------------------------------------------
" Usability options {{{1
"
" These are options that users frequently set in their .vimrc. Some of them
" change Vim's behaviour in ways which deviate from the true Vi way, but
" which are considered to add usability. Which, if any, of these options to
" use is very much a personal preference, but they are harmless.

" Use case insensitive search, except when using capital letters
" 検索時に大文字・小文字を区別しない。ただし、検索後に大文字小文字が
" 混在しているときは区別する
set ignorecase
set smartcase

" Allow backspacing over autoindent, line breaks and start of insert action
" オートインデント、改行、インサートモード開始直後にバックスペースキーで
" 削除できるようにする。
set backspace=indent,eol,start

" When opening a new line and no filetype-specific indenting is enabled, keep
" the same indent as the line you're currently on. Useful for READMEs, etc.
set autoindent " 改行時に前の行のインデントを継続する
set smartindent " 改行時に前の行の構文をチェックし次の行のインデントを増減する

" Stop certain movements from always going to the first character of a line.
" While this behaviour deviates from that of Vi, it does what most users
" coming from other editors would expect.
" 移動コマンドを使ったとき、行頭に移動しない
set nostartofline

" Display the cursor position on the last line of the screen or in the status
" line of a window
" 画面最下行にルーラーを表示する
set ruler

" Always display the status line, even if only one window is displayed
" ステータスラインを常に表示する
set laststatus=2

" Instead of failing a command because of unsaved changes, instead raise a
" dialogue asking if you wish to save changed files.
" バッファが変更されているとき、コマンドをエラーにするのでなく、保存する
" かどうか確認を求める
set confirm

" Use visual bell instead of beeping when doing something wrong
" ビープの代わりにビジュアルベル(画面フラッシュ)を使う
set visualbell

" And reset the terminal code for the visual bell.  If visualbell is set, and
" this line is also included, vim will neither flash nor beep.  If visualbell
" is unset, this does nothing.
" そしてビジュアルベルも無効化する

" Use <F11> to toggle between 'paste' and 'nopaste'
" <F11>キーで'paste'と'nopaste'を切り替える
set pastetoggle=<F11>


"------------------------------------------------------------
" Indentation options {{{1
" インデント関連のオプション {{{1
"
" Indentation settings according to personal preference.

" Indentation settings for using 2 spaces instead of tabs.
" Do not change 'tabstop' from its default value of 8 with this setup.
" タブ文字の代わりにスペース2個を使う場合の設定。
" この場合、'tabstop'はデフォルトの8から変えない。
