-# Name: Solarized Flood
-# Changed: June 3 2018
-# Maintainer: https://github.com/Neur1n
-# Description:
-#   A vim-airline theme made based on and tested with the Solarized colorscheme
-#   (https://github.com/frankier/neovim-colors-solarized-truecolor-only) in
-#   Windows 10 OS and GVim 8.1.
-#
-#   This script is based on the 'dark' theme. The 'inactive' and 'ctrlp' parts
-#   were not changed.
-#
-#   It is call 'flood' since the statusline and the tabline will be highlighted
-#   with the 'base03' color in Solarized (dark). If you use the dark Solarized
-#   colorscheme for Vim and, in Windows, set 'Personalization-Colors-Choose
-#   your color - Custom color' to be '#002B36' (*), then most parts of the GVim
-#   window will be 'flooded' with the color.
-#   NOTE: This will make some components of the airline less distinguishable
-#         from the others. If anyone has better ideas, I will be happy to take
-#         a conversation with you. :)

-## For package maintainers
-
-If you are a package maintainer for a repository of Linux distribution, etc.
-you may provide a package-specific setting by preparing
-a file `/path/to/blesh/lib/_package.sh` (e.g. `/usr/share/blesh/lib/_package.sh`)
-which will be sourced after the load of `ble.sh` just before sourcing user's configuration (`~/.blerc`).
-
-- In the file, the shell variable `_ble_base_package_type=TYPE` should be
-   set up to have a repository-specific name (such as `AUR`). 
-
-- The function named `ble/base/package:TYPE/update` (where `TYPE`
-  matches with a value assigned to `_ble_base_package_type`) may be
-  provided to define a custom updating procedure.  The exit status of the function can be
-  - `0` ... when the update successed
-  - `6` ... when the update was skipped because the package was up to date.
-  - `125` ... when it wants to fallback to the built-in updating procedure of `ble.sh`.
-  - Other ... when the update failed
-
-An example `lib/_package.sh` might be
-
-```bash
-_ble_base_package_type=apt
-
-function ble/base/package:apt/update {
-  sudo apt upgrade blesh
-}
-```
-
-You can also find a real example for AUR (Arch User Repository) [here](https://aur.archlinux.org/cgit/aur.git/tree/blesh-update.sh?h=blesh-git).
-
-## Summary of codebase
-
-The core script file `ble.sh` is generated by combining the following files:
-
-- `ble.pp` ... Basic initialiation
-- `src/def.sh` ... Prototype definitions
-- `src/util.sh` ... Basic utility functions
-- `src/decode.sh` ... User-input decoder and keybindings
-- `src/color.sh` ... Terminal graphic attributes
-- `src/canvas.sh` ... Terminal layout engine
-  - `src/canvas.emoji.sh` ... Emoji database
-- `src/history.sh` ... Command history management
-- `src/edit.sh` ... Line editor
-- `src/benchmark.sh` ... Measure processing time
-- `lib/core-completion.sh` ... Prototype definition for completions
-- `lib/core-syntax.sh` ... Prototype definitions for syntax analyzer
-
-Useful features are implemented in separate modules:
-
-- `keymap/vi.sh` ... Vim mode
-  - `lib/vim-arpeggio.sh` ... `vim-arpeggio`-like plugin
-  - `lib/vim-surround.sh` ... `vim-surround`-like plugin
-- `keymap/emacs.sh` ... Emacs mode
-- `lib/core-syntax.sh` ... Shell parser and syntax highlighting
-  - `lib/core-syntax-ctx.def` ... Definition of parser states
-- `lib/core-complete.sh` ... Completions including `menu-complete`, `auto-complete`, `menu-filter`, `dabbrev`, `sabbrev`, etc.
-
-The following files are initialization scripts:
-
-- `lib/init-term.sh` ... Initialize terminal escape sequences (host-to-terminal, i.e. control sequences)
-- `lib/init-cmap.sh` ... Initialize terminal escape sequences (terminal-to-host, i.e. key sequences)
-- `lib/init-bind.sh` ... Initialize readline attacher
-- `lib/init-msys1.sh` ... Workaround for MSYS1 with broken pipes
-  - `lib/init-msys1-helper.c` ... Helper C program for the workaround of broken pipes
-
-## Tests
-
-Tests can be run by one of the following commands:
-
-```bash
-$ make check
-$ make check-all
-$ bash out/ble.sh --test
-
-```
-
-Currently test coverage is very small
-partly because the testing for interactive behavior and terminal rendering results is hard.
-Nevertheless, the tests are defined in the following files:
-
-- `lib/core-test.sh` ... Library for tests
-- `lib/test-main.sh`
-- `lib/test-util.sh`
-- `lib/test-canvas.sh`
-- `lib/test-edit.sh`
-- `lib/test-complete.sh`
-- `lib/test-syntax.sh`

-    実際に呼び出された順序と異なる順序で処理が実行されてしまっていた。
-    記録を一つの配列 _ble_faces_lazy_loader にまとめ、順序が保存される様にした。
-
-## 2015-12-25
-* (ble-color) \change ble-color-{def,set}face の処理も遅延する。

-  * (ble-syntax): \new local variable `parse_suppressNextStat` in ble-syntax/parse.
-  * (ble-syntax:bash): \bugfix, correct resume for `var+`, `arr[...]+` -> `var+=`, `arr[...]+=`.
-  * (ble-syntax:bash): \new, support `a=([key]=value)` and `a+=([key]+=delta)`.
-* (ble-syntax:bash): \new context CTX_CASE.
-* (ble-syntax:bash): \new CTX_COND{X,I}; \change unexpected '(' is treated as extglob '@(' instead of sub-shell '(';
-  * ble-syntax.sh: `CTX_VAL{X,I}` から `CTX_COND{X,I}` を分離。
-  * ble-syntax.sh: コマンド中に現れる '(' を extglob の括弧として取り扱う事にする。
-    今迄は暫定的に sub-shell として取り扱っていたが、
-    エラーが多く出てうるさいのでエラーの少ない extglob 括弧として取り扱う事にする。
-* ble-edit.sh: \bugfix histexpand condition [[ -o histexpand ]] inverted.
-  * \bugfix 履歴展開が効かなくなっていた。
-    条件判定の誤りだった: [[ -o histexpand ]] → [[ ! -o histexpand ]]
-  * \bugfix 履歴展開に失敗した時に : が実行される。
-    履歴展開が失敗すると history -p は標準出力に何も出力しないためであった。
-    失敗した時は echo "$BASH_COMMAND" により手動で出力する。
-* (ble-syntax:bash): \support shopt -s extglob; \bugfix error on {delimiter after redirect,'<' redirect};

-* (ble-syntax:bash): special treatment of arguments of `declare`.
-  * (ble-syntax:bash): declare, typeset, local, export, alias コマンドの引数を文法的に特別に扱う。特に配列構文 =() を許容する。
-    その為に新しい文脈値 `CTX_ARGVX`, `CTX_ARGVI` を追加する。
-  * (ble-syntax:bash): `CTX_ARGVI` に対する補完候補は変数名。等号 '=' 以降の部分についてはファイル名の補完候補を列挙する。
-  * (ble-syntax:bash): 通常の代入構文における配列構文の動作を変更。
-    今迄は a=(1 2 3)echo などとすると a=(1 2 3) を配列代入と解釈し echo の部分をコマンドと解釈する様にしていた。
-    その為に配列構文の nest-pop 時にすぐに単語を抜けて cxt==CTX_CMDXV になる様に構成していた。
-    しかし、実際の bash の動作を確認してみると、a=(1 2 3)echo は a='(1 2 3)echo' の様に、全体が代入文の右辺と解釈される様である。
-    実際の bash の動作に合わせて、nest-pop 時に特別な動作を特にしない様に変更した。

-    - ble-edit.sh: bash-3.1 で C-d を捕捉できる様に(結構無理のある方法だが)。
-    - ble-edit.sh, ble-decode.sh: bugfix, bash-3 でカーソルキーの類が動かない。履歴が読み込まれていない。
-    - ble-edis.sh: bash-3.1, bleopt_suppress_bash_output=1 の方が安定して動いているのでこちらで行く。
-    - ble-edit.sh: bash-3.1, カーソルキーが効かない。例によって ESC [ ... に関係するコマンドで
-      keymap が見付からないエラーになっている。これは ESC [ を CSI (utf-8) に変換してから読み取る事にした。
-    - ble-syntax.sh: bash-3.2.48 のバグの work-around, (()) 内で配列要素を参照すると制御が無条件に其処に跳ぶ。
-
-## 2015-02-17
-  * ble-edit.sh (ble-edit/dirty-range): 範囲更新の仕組みを追加。
-      _ble_edit_dirty はプロンプト再描画の判定も兼ねているので取り敢えず残す。
-  * ble-edit.sh: 変数リーク (グローバル変数の汚染) の修正。line i
-  * ble-syntax.sh (ctx-command/check-word-end): 単語終了判定の処理タイミングを変更。
-  * ble-syntax.sh: context の追加。CTX_CMDXF CTX_CMDX1 CTX_CMDXV CTX_ARGX0
-    より正確な文脈判定・エラー検知。
-  * ble-syntax.sh: 他にも多くの修正がある。未だ修正が続きそうなので一旦 commit する。
-
-  * ble-edit.sh (accept-line): bug, - で始まるコマンドを実行できない。
-  * ble-color.sh: [bug] bg=black を設定しても反映されない。
-    "未設定" と "黒" を区別する様に修正。
-  * ble-syntax (ble-syntax-highlight+syntax): 入れ子エラーの色の範囲
-  * ble-syntax: m, ;& は ;; ;;& 等と同じ取り扱い
-  * ble-syntax, etc: bash-3 正規表現対策。bash-3/4 の正規表現の違いに依存しない書き方に変更。
-
-## 2015-02-16
-  * ble-syntax.sh: bugfix, incremental に更新した時に word の長さが更新されない。
-    _ble_syntax_word への格納の際に失敗していた。
-
-## 2015-02-15
-  * ble-synatax.sh: bash の文法に従った incremental な解析と色付け。
-
-## 2015-02-14
-  * ble-edit.sh (.ble-line-info.draw): 表示が遅いので修正。
-    ASCII 文字は特別扱いする様に改良。劇的に速くなった。
-
-## 2015-02-13
-  * ble-edit.sh (keymap emacs): 既定の keymap に emacs の名を付与。
-  * ble-edit.sh (accept-line.exec): bugfix, C-c で再帰呼び出しのループから抜けられない。
-    trap DEBUG を用いて再帰呼び出しから抜けられる様に exec 周りを整理・実装し直し。
-  * ble-edit.sh: オプション名の変更、各オプションの整理・説明の追加。
-  * ble-edit.sh (.ble-edit/gexec): グローバルな文脈でコマンドを実行する仕組み。
-    再帰呼出に対する C-c にも対応。bleopt_exec_type で実行の方法を切り替えられる様に。
-    exec が従来の方法で gexec がこの新しい方法。
-
-## 2015-02-12
-  * ble-decode.sh: bugfix, exit 後に stty が壊れているのを修正
-    これに伴って ble の detach 機能の実装も行った。
-  * ble-decode.sh: bugfix, bash-4.3 で三文字以上のシーケンスが悉く聞かない。
-    keymap が見付からないエラーになってしまうので全てのシーケンスについて bind -x する事にした。
-  * ble-core.sh: bugfix, builtin printf \U.... の使えない環境で command printf fallback が働かない。
-    printf のパスを修正。また ASCII に対しては printf は使わない様に変更。
-  * ble-color.sh (ble-syntax-highlight+default):
-    追加・修正。また選択範囲の反転を ble-syntax-highlight+region として実装し、それを呼び出す形に。
-  * ble.pp: 起動時に interactive モードかどうかのチェックを行う様に。
-
-## 2015-02-11
-  * ble-edit.sh (_ble_edit_io_*): ちらつきを抑える為に stdout/stderr を切り替える事にした。
-    ちらつくのは bash の既定の出力によって ble の表示がクリアされ、bash の表示したい物が表示されるから。
-    これに対抗して ble は bash の出力の直後に上書き再描画して何とか表示していた。
-    bash の既定の出力を抑える為に、exec で出力先を切り替える事にした。
-    bash の出力はファイルに書き込まれる様にし向ける。出力先ファイルを逐次確認して、
-    エラーが出力されていれば visible-bell で表示する事にした。
-    `bleopt_suppress_bash_output=1` の時にこの新しい方法を実験的に用いる。
-    `bleopt_suppress_bash_output=` の時は従来のちらつく方法。
-
-## 2015-02-10
-  * ble-edit.sh (accept-line.exec): bash-4.3 で内部からグローバル変数を定義できる様に
-    declare 及び typeset を上書きして -g オプションを指定する様に変更。
-    また、これに関係する注意点を ble.htm に記述。
-  * ble-edit.sh (history): ロードに時間が掛かるので最適化。
-  * 全般: bugfix, 文字列分割で GLOBIGNORE='*' を設定していないとパス名展開されて危険
-  * ble-color.sh (ble-syntax-highlight+default): より良い色づけ。
-  * ble-edit.sh (accept-line.exec): ble-bind -cf で bind されたコマンドの実行コンテキストを変更。
-    accept-line で実行されるのと同じコンテキストで実行する。
-  * ble-edit.sh (keymap default): C-z M-z を fg に bind。
-
-## 2015-02-09
-  * git repos
-  * ble-edit: bugfix, locate-xword マクロが展開されていなかった
-  * ble-decode: bash-4.3 に対応する為に色々変更
-    - bind 指定の場合分けを整理
-    - bugfix, ESC ?, ESC [ ? に対して全て bind
-    - bugfix, 場合によって全く bind -r できていない
-      →"bind -sp | fgrep" が "バイナリ" という結果になる事がある様だ。
-        fgrep に -a を指定する。
-    - bugfix, 日本語が入力できない。8bit 文字が認識されない。
-      →8bit 文字はエスケープシーケンスで bind に指定する様に変更。

-  * ble.sh:
-
-    -- 経緯 --
-    highlight.sh の方針だと bash が表示する編集中の内容を消す事が出来ないし、
-    カーソルの位置も bash が表示する物の場所を指している。
-    色を付けて表示した物は、補助的に bash が表示する物の下に並べて表示する
-    ぐらいしか方法がない。
-
-    また readline 関数をスクリプトから呼び出す事が出来ないので、
-    結局、色付けを更新したいタイミングで READLINE_LINE や READLINE_POINT の動作を
-    スクリプトの側で全て模倣して再現しなければならない。
-    READLINE_LINE, READLINE_POINT の bash の仕様が変な所為で、日本語など
-    のマルチバイトで正しく処理する為に、色々と汚い事をしなければならない。
-
-    以上の事から、文字列の編集などの操作からスクリプトの実行まで
-    全部自分で好きな様に実装して bash readline の機能を全て上書きする事にした。
-    その為に、スクリプトを新しく書き直す。zle を真似て ble (bash line editor)
-    と名付ける。
-
-    -- 方針としては --
-    a. read -n 1 を用いて 1 文字ずつ標準入力から文字を取り出してそれを処理していく
-    b. bash の bind で全ての文字に ble のバイト受信関数を繋げて、
-       バイト列を受信しながら処理する。
-
-    highlight.sh の延長線上で b. の方針にしたが、
-    もしかすると a. の方針も可能かも知れない。

-
-`ble.sh` (*Bash Line Editor*) はピュア Bash スクリプトで書かれたコマンドラインエディタで、標準の GNU Readline を置き換える形で動作します。
-
-現在の開発バージョンは 0.4 です。
-このスクリプトは Bash 3.0 以降で利用できますが、速度・機能などの観点から 4.0 以降ののリリース版 Bash でお使い頂くことがお薦めです。
-現時点では、文字コードとして `UTF-8` のみの対応です。
-このスクリプトは [**BSD License**](LICENSE.md) (3条項 BSD ライセンス) の下で提供されます。
-
-免責: ラインエディタ本体は **ピュア Bash** で書かれていますが、
-ユーザーコマンド実行時には TTY 設定の為に `stty` (POSIX) を呼び出します。
-他にも処理の高速化の為に、初期化・終了処理、
-巨大なデータの処理 (補完、貼り付けなど) の局面でPOSIX 標準コマンドを利用しています。
-
-呼称: `ble.sh` はお好きな様に読んでいただいて問題ありませんが、一番短いのは標記の /blɛʃ/ になりましょう。
-しかし個人的には脳裡で /biːɛliː dɑt ɛseɪtʃ/ と読んでいるものですから、標記の読み方は飽くまで参考と受け止めていただければ幸いです。
-
-## 簡単設定
-
-`ble.sh` インストールには `git`, `make` (GNU make), and `gawk` が必要です。
-詳細は、試用またはインストールに関しては [節1.1](#get-from-source) と [節1.2](#get-from-tarball) を、
-`~/.bashrc` の設定に関しては [節1.3](#set-up-bashrc) を御覧ください。
-以下、GNU make が `gmake` として提供されているシステム (BSD など) では `make` を `gmake` に置き換えて実行してください。
-
-```bash
-# 簡単お試し (インストールせずにお試しいただけます)
-
-git clone --recursive https://github.com/akinomyoga/ble.sh.git
-make -C ble.sh
-source ble.sh/out/ble.sh
-
-# インストール & .bashrc 簡単設定 (動かない場合は節1.3を御参照下さい)
-
-git clone --recursive https://github.com/akinomyoga/ble.sh.git
-make -C ble.sh install PREFIX=~/.local
-echo 'source ~/.local/share/blesh/ble.sh' >> ~/.bashrc
-
-# 更新 (ble.sh をロードした状態で)
-
-ble-update
-
-# 更新 (ble.sh 外部から)
-
-bash /path/to/ble.sh --update
-
-# パッケージ作成用コマンド
-
-git clone --recursive https://github.com/akinomyoga/ble.sh.git
-make -C ble.sh install DESTDIR=/tmp/blesh-package PREFIX=/usr/local
-```
-
-パッケージ管理システムを通じて `ble.sh` をインストールする事もできます (現在 AUR のみ)。

-## 機能概要
-
-- **構文着色**: `fish` や `zsh-syntax-highlighting` のような文法構造に従った着色を行います。
-  `zsh-syntax-highlighting` のような単純な着色ではなく、構文の入れ子構造や複数のヒアドキュメントなども正しく解析して着色します。
-  着色は[全て設定可能](https://github.com/akinomyoga/ble.sh/wiki/%E8%AA%AC%E6%98%8E%E6%9B%B8-%C2%A72-%E6%8F%8F%E7%94%BB)です。
-- **補完増強**: [補完](https://github.com/akinomyoga/ble.sh/wiki/%E8%AA%AC%E6%98%8E%E6%9B%B8-%C2%A77-%E8%A3%9C%E5%AE%8C)を大幅に増強します。
-  **文法構造に応じた補完**、クォートやパラメータ展開を展開した上でのプログラム補完、**曖昧補完**に対応しています。
-  また、候補をカーソルキーや <kbd>TAB</kbd>, <kbd>S-TAB</kbd> で選択できる
-  [**メニュー補完**](https://github.com/akinomyoga/ble.sh/wiki/%E8%AA%AC%E6%98%8E%E6%9B%B8-%C2%A77-%E8%A3%9C%E5%AE%8C#user-content-sec-menu-complete)、
-  `fish` や `zsh-autosuggestions` のような
-  [**自動補完**](https://github.com/akinomyoga/ble.sh/wiki/%E8%AA%AC%E6%98%8E%E6%9B%B8-%C2%A77-%E8%A3%9C%E5%AE%8C#user-content-sec-auto-complete)
-  (Bash 4.0 以上) の機能もあります。
-  更に、従来 `peco` や `fzf` を呼び出さなければならなかった補完候補の絞り込みも
-  [**メニュー絞り込み**](https://github.com/akinomyoga/ble.sh/wiki/%E8%AA%AC%E6%98%8E%E6%9B%B8-%C2%A77-%E8%A3%9C%E5%AE%8C#user-content-sec-menu-filter)
-  (Bash 4.0 以上) として自然な形で組み込んでいます。
-  他に、[**動的略語展開**](https://github.com/akinomyoga/ble.sh/wiki/%E8%AA%AC%E6%98%8E%E6%9B%B8-%C2%A77-%E8%A3%9C%E5%AE%8C#user-content-sec-dabbrev)
-  や、[*zsh abbreviations*](https://unix.stackexchange.com/questions/6152/zsh-alias-expansion)・[`zsh-abbr`](https://github.com/olets/zsh-abbr) のような
-  [**静的略語展開**](https://github.com/akinomyoga/ble.sh/wiki/%E8%AA%AC%E6%98%8E%E6%9B%B8-%C2%A77-%E8%A3%9C%E5%AE%8C#user-content-sec-sabbrev)
-  にも対応しています。
-- **Vim編集モード**: `set -o vi` による編集モードを増強します。
-  挿入・ノーマルモードの他に(行・矩形)ビジュアルモード、置換モードなどの各種モードに対応しています。
-  テキストオブジェクト・各種レジスタ・オペレータ・キーボードマクロなどにも対応しています。
-  拡張として `vim-surround` も提供しています。
-- 他にも
-  [**ステータス行**](https://github.com/akinomyoga/ble.sh/wiki/%E8%AA%AC%E6%98%8E%E6%9B%B8-%C2%A74-%E7%B7%A8%E9%9B%86#user-content-bleopt-prompt_status_line),

-  など様々な機能に対応しています。
-
-注意: `ble.sh` は、(プロンプト (`PS1`)、エイリアス、関数などを提供する) 典型的な Bash 設定集と異なります。
-`ble.sh` はより低層の基盤を提供するもので、ユーザは自分でプロンプトやエイリアスを設定する必要があります。
-勿論 [`bash-it`](https://github.com/Bash-it/bash-it) や [`oh-my-bash`](https://github.com/ohmybash/oh-my-bash) の様な他の Bash 設定と一緒に使っていただくことも可能です。

-## これまでとこれから
-
-このプロジェクトは初めは `.bashrc` の片隅で行われた小さな実験からスタートしました。
-2013年5月に `zsh-syntax-highlighting` のとある記事に触発されたのがきっかけでした。
-初めは数百行のコードを書けば構文着色が簡単に実現できるのではないかと思って始めた実験ですが、
-すぐに行エディタを根本から書き直さなければ実現できないのではないかということが分かり、
-独立したファイルにコードを移動した後に `ble.sh` という名前を与えました。
-この名前は Zsh の行エディタ (*ZLE* (*Zsh Line Editor*)) を真似て、
-但しシェルで書かれているという事を意識して `.sh` という拡張子にしたように記憶しています。
-`ble.sh` の読み方について屡々訊かれるのですが、最初に書いたように特に定まった読み方はありません。
-最初の実験は2週間程コードを弄って原理的に行エディタを作れるという事を結論づけて終わりました。
-本格的な実装が始まったのは2015年2月の事で12月には公開しました。
-その時点で行エディタとしては普段遣いに堪える程度に完成していました。
-Vimモードの実装は2017年9月に始まり2018年3月に一先ず完成としました。
-続いて補完の拡張は2018年8月に始まり2019年2月には一通り完成しました。
-現在は漫然とメンテナンスしている所でいつになるかは分かりませんが、以下に挙げるような機能も加えたいと何となく考えています。

-# 1 使い方
-
-## 1.1 最新の git repository のソースから生成して試す (バージョン ble-0.4)<sup><a id="get-from-source" href="#get-from-source">†</a></sup>
-
-### ble.sh 生成
-
-`ble.sh` を生成する為には `gawk` (GNU awk) と `gmake` (GNU make) が必要です。
-以下のコマンドで生成できます。
-GNU make が `gmake` という名前でインストールされている場合は、`make` の代わりに `gmake` として下さい。
-```console
-$ git clone --recursive https://github.com/akinomyoga/ble.sh.git
-$ cd ble.sh
-$ make
-```
-スクリプトファイル `ble.sh` がサブディレクトリ `ble.sh/out` 内に生成されます。
-
-### 試用
-
-生成された `ble.sh` は `source` コマンドを用いてお試しいただけます。
-
-```console
-$ source out/ble.sh
-```
-
-### インストール
-
-指定したディレクトリにインストールするには `make install` コマンドを使用します。
-
-```bash
-# ~/.local/share/blesh にインストール
-make install
-
-# 指定したディレクトリにインストール
-make install INSDIR=/path/to/blesh
-
-# パッケージ作成用 (パッケージ管理者用)
-make install DESTDIR=/tmp/blesh-package PREFIX=/usr/local
-```
-
-Make 変数 `DESTDIR` または `PREFIX` が指定されている時、`ble.sh` は `$DESTDIR/$PREFIX/share/blesh` にコピーされます。
-それ以外で Make 変数 `INSDIR` が指定されている時、直接 `$INSDIR` にインストールされます。
-更にそれ以外で環境変数 `$XDG_DATA_HOME` が指定されている時、`$XDG_DATA_HOME/blesh` にインストールされます。
-以上の変数が何れも指定されていない時の既定のインストール先は `~/.local/share/blesh` です。
-
-`.bashrc` の設定に関しては[節1.3](#set-up-bashrc)を御覧ください。
-
-## 1.2 GitHub Releases から tar をダウンロードして使う<sup><a id="get-from-tarball" href="#get-from-tarball">†</a></sup>
-
-ダウンロード・試用・インストールの方法については各リリースページの説明を御覧ください。
-現在、安定版は開発版に比べてかなり古いので様々な機能が欠けている事にご注意下さい。
-
-- 開発版 [v0.4.0-devel2](https://github.com/akinomyoga/ble.sh/releases/tag/v0.4.0-devel2) (2020-12)
-- 安定版 [v0.3.3](https://github.com/akinomyoga/ble.sh/releases/tag/v0.3.3) (2019-02 fork) 拡張補完
-- 安定版 [v0.2.6](https://github.com/akinomyoga/ble.sh/releases/tag/v0.2.6) (2018-03 fork) Vim モード
-- 安定版 [v0.1.14](https://github.com/akinomyoga/ble.sh/releases/tag/v0.1.14) (2015-12 fork) 構文着色
-
-## 1.2 `ble.sh` をダウンロードして試す (旧バージョン ble-0.3 201902版)<sup><a id="get-from-tarball" href="#get-from-tarball">†</a></sup>
-
-`wget` を使う場合:
-```console
-$ wget https://github.com/akinomyoga/ble.sh/releases/download/v0.3.3/ble-0.3.3.tar.xz
-$ tar xJf ble-0.3.3.tar.xz
-$ source ble-0.3.3/ble.sh
-```
-`curl` を使う場合:
-```console
-$ curl -LO https://github.com/akinomyoga/ble.sh/releases/download/v0.3.3/ble-0.3.3.tar.xz
-$ tar xJf ble-0.3.3.tar.xz
-$ source ble-0.3.3/ble.sh
-```
-
-指定したディレクトリに `ble.sh` を配置するには単に `ble-0.1.7` ディレクトリをコピーします。
-```console
-$ cp -r ble-0.3.3 /path/to/blesh
-```
-
-## 1.3 `.bashrc` に設定する<sup><a id="set-up-bashrc" href="#set-up-bashrc">†</a></sup>
-
-対話シェルで常用する場合には `.bashrc` に設定を行います。
-単に `ble.sh` を `source` して頂くだけでも大抵の場合動作しますが、
-より確実に動作させる為には以下の様にコードを記述します。
-```bash
-# bashrc
-
-# .bashrc の先頭近くに以下を追加して下さい。
-[[ $- == *i* ]] && source /path/to/blesh/ble.sh --noattach
-
-# 間に通常の bashrc の内容を既述します。
-
-# .bashrc の末端近くに以下を追加して下さい。
-[[ ${BLE_VERSION-} ]] && ble-attach
-```
-
-## 1.4 初期化スクリプト `~/.blerc` について
-
-ユーザー設定は初期化スクリプト `~/.blerc` (またはもし `~/.blerc` が見つからなければ `${XDG_CONFIG_HOME:-$HOME/.config}/blesh/init.sh`) に記述します。
-テンプレートとしてリポジトリの [`blerc`](https://github.com/akinomyoga/ble.sh/blob/master/blerc) というファイルを利用できます。
-初期化スクリプトは `ble.sh` ロード時に自動で読み込まれる Bash スクリプトなので、Bash で使えるコマンドを初期化スクリプトの中で利用できます。
-初期化スクリプトの位置を変更する場合には、`source ble.sh` 時に `--rcfile INITFILE` を指定します。以下に例を挙げます。
-
-```bash
-# in bashrc
-
-# Example 1: ~/.blerc will be used by default
-[[ $- == *i* ]] && source /path/to/blesh/ble.sh --noattach
-
-# Example 2: /path/to/your/blerc will be used
-[[ $- == *i* ]] && source /path/to/blesh/ble.sh --noattach --rcfile /path/to/your/blerc
-```
-
-## 1.5 アップデート
-
-Git (`git'), GNU awk (`gawk`), 及び GNU make (`make`) が必要になります。
-`ble-0.3` 以上をお使いの場合は `ble.sh` をロードした状態で `ble-update` を実行して下さい。
-
-```bash
-$ ble-update
-```
-
-`ble-0.4` 以上をお使いの場合は `ble.sh` をロードしなくても以下のコマンドで更新可能です。
-
-```bash
-$ bash /path/to/ble.sh --update
-```
-
-それ以外の場合には、以下のように `git pull` で最新版を入手・インストールできます。
-
-```bash
-cd ble.sh   # ※既に持っている git リポジトリに入る
-git pull
-git submodule update --recursive --remote
-make
-make INSDIR="$HOME/.local/share/blesh" install
-```
-
-## 1.6 アンインストール
-
-基本的に `ble.sh` ディレクトリとユーザの追加した設定を単に削除していただければ問題ありません。
-
-- 全ての `ble.sh` セッション (`ble.sh` をロードしている Bash 対話セッション) を終了します。
-- `.bashrc` に追加した行があれば削除します。
-- `blerc` 設定ファイル (`~/.blerc` または `~/.config/blesh/init.sh`) があれば削除します。
-- `ble.sh` をインストールしたディレクトリを削除します。
-- キャッシュディレクトリ `~/.cache/blesh` が生成されていればそれを削除します。
-- 一時ディレクトリ `/tmp/blesh` が生成されていればそれを削除します。これは `/tmp` の内容が自動的にクリアされないシステムで必要です。
-
-# 2 基本設定
-
-ここでは `~/.blerc` に記述する基本的な設定を幾つか紹介します。
-[質問と回答](https://github.com/akinomyoga/ble.sh/wiki/%E8%B3%AA%E5%95%8F%E3%81%A8%E5%9B%9E%E7%AD%94)、
-[逆引きレシピ](https://github.com/akinomyoga/ble.sh/wiki/%E9%80%86%E5%BC%95%E3%81%8D%E3%83%AC%E3%82%B7%E3%83%94)、
-[`contrib` リポジトリ](https://github.com/akinomyoga/blesh-contrib/blob/master/README-ja.md) にも便利な設定があります。
-その他の全ての設定項目はテンプレート [`blerc`](https://github.com/akinomyoga/ble.sh/blob/master/blerc) に含まれています。
-詳細な説明に関しては[説明書](https://github.com/akinomyoga/ble.sh/wiki/%E7%9B%AE%E6%AC%A1)を参照して下さい。
-
-## 2.1 Vim モード
-
-Vim モードについては [Wiki の説明ページ](https://github.com/akinomyoga/ble.sh/wiki/Vi-(Vim)-editing-mode) を御覧ください。
-
-## 2.2 各機能の無効化
-
-よくお尋ね頂くご質問の一つにそれぞれの機能をどのように無効化すれば良いのかというものが御座います。
-各機能の無効化方法を以下にまとめます。
-
-```bash
-# 構文着色を無効化
-bleopt highlight_syntax=
-
-# ファイル名に基づく構文着色を無効化
-bleopt highlight_filename=
-
-# 変数の種類に基づく構文着色の無効化
-bleopt highlight_variable=
-
-# 自動補完の無効化 (自動補完は Bash 4.0 以降にて既定で有効です)
-bleopt complete_auto_complete=
-# Tip: 代わりに自動補完の起動遅延をミリ秒単位でご指定いただくこともできます。
-bleopt complete_auto_delay=300
-
-# コマンド履歴に基づく自動補完の無効化
-bleopt complete_auto_history=
-
-# 曖昧補完の無効化
-bleopt complete_ambiguous=
-
-# TAB によるメニュー補完の無効化
-bleopt complete_menu_complete=
-
-# メニュー自動絞り込みの無効化 (Bash 4.0 以降にて既定で有効化されます)
-bleopt complete_menu_filter=
-
-# 行末マーカー "[ble: EOF]" の無効化
-bleopt prompt_eol_mark=''
-# Tip: 代わりに他の文字列をご指定頂くこともできます。
-bleopt prompt_eol_mark='⏎'
-
-# 終了ステータスマーカー "[ble: exit %d]" の無効化
-bleopt exec_errexit_mark=
-# Tip: 代わりに他の文字列をご指定頂くこともできます。
-bleopt exec_errexit_mark=$'\e[91m[error %d]\e[m'
-
-# コマンド実行時間マーカー "[ble: elapsed 1.203s (CPU 0.4%)]" の無効化
-bleopt exec_elapsed_mark=
-# Tip: 代わりに別の文字列をご指定いただくこともできます。
-bleopt exec_elapsed_mark=$'\e[94m[%ss (%s %%)]\e[m'
-# Tip: マーカーを表示する条件を変更することも可能です。
-bleopt exec_elapsed_enabled='sys+usr>=10*60*1000' # 例: 合計CPU時間が 10 分以上の時に表示
-```
-
-## 2.3 曖昧文字幅
-
-設定 `char_width_mode` を用いて、曖昧文字幅を持つ文字 (Unicode 参考特性 `East_Asian_Width` が `A` (Ambiguous) の文字) の幅を制御できます。
-現在は 4 つの選択肢 `emacs`, `west`, `east`, `auto` が用意されています。
-設定値 `emacs` を指定した場合、GNU Emacs における既定の文字幅と同じ物を使います。
-設定値 `west` を指定した場合、全ての曖昧文字幅を 1 (半角) と解釈します。
-設定値 `east` を指定した場合、全ての曖昧文字幅を 2 (全角) と解釈します。
-設定値 `auto` を指定した場合、`west` か `east` かを端末とのやり取りに基づいて自動判定します。
-既定値は `auto` です。この設定項目は、利用している端末の振る舞いに応じて適切に設定する必要があります。
-例えば `west` に設定する場合は以下の様にします:
-
-```bash
-bleopt char_width_mode='west'
-```
-
-## 2.4 文字コード
-
-設定 `input_encoding` は入力の文字コードを制御するのに使います。現在 `UTF-8` と `C` のみに対応しています。
-設定値 `C` を指定した場合は、受信したバイト値が直接文字コードであると解釈されます。
-既定値は `UTF-8` です。`C` に設定を変更する場合には以下の様にします:
-
-```bash
-bleopt input_encoding='C'
-```
-
-## 2.5 ベル
-
-設定 `edit_abell` と設定 `edit_vbell` は、編集関数 `bell` の振る舞いを制御します。
-`edit_abell` が非空白の文字列の場合、音による通知が有効になります (つまり、制御文字の `BEL` (0x07) が `stderr` に出力されます)。
-`edit_vbell` が非空白の文字列の場合、画面での通知が有効になります。既定では音による通知が有効で、画面での通知が無効になっています。
-
-設定 `vbell_default_message` は画面での通知で使用するメッセージ文字列を指定します。既定値は `' Wuff, -- Wuff!! '` です。
-設定 `vbell_duration` は画面での通知を表示する時間の長さを指定します。単位はミリ秒です。既定値は `2000` です。
-
-例えば、画面での通知は以下のように設定・有効化できます:
-```bash
-bleopt edit_vbell=1 vbell_default_message=' BEL ' vbell_duration=3000
-```
-
-もう一つの例として、音による通知は以下の様にして無効化できます。
-```bash
-bleopt edit_abell=
-```
-
-## 2.6 着色の設定
-
-構文に従った着色で使用される、各文法要素の色と属性は `ble-face` シェル関数で設定します。
-既定の設定は以下のコードに対応します:
-```bash
-# 編集に関連する着色の設定
-ble-face -s region                    bg=60,fg=white
-ble-face -s region_target             bg=153,fg=black
-ble-face -s region_match              bg=55,fg=white
-ble-face -s region_insert             fg=12,bg=252
-ble-face -s disabled                  fg=242
-ble-face -s overwrite_mode            fg=black,bg=51
-ble-face -s auto_complete             fg=238,bg=254

-ble-face -s filename_orphan           underline,fg=teal,bg=224
-ble-face -s filename_executable       underline,fg=green
-ble-face -s filename_setuid           underline,fg=black,bg=220
-ble-face -s filename_setgid           underline,fg=black,bg=191
-ble-face -s filename_other            underline
-ble-face -s filename_socket           underline,fg=cyan,bg=black
-ble-face -s filename_pipe             underline,fg=lime,bg=black
-ble-face -s filename_character        underline,fg=white,bg=black
-ble-face -s filename_block            underline,fg=yellow,bg=black
-ble-face -s filename_warning          underline,fg=red
-ble-face -s filename_url              underline,fg=blue
-ble-face -s filename_ls_colors        underline

-ble-face -s varname_export            fg=200,bold
-ble-face -s varname_expr              fg=92,bold
-ble-face -s varname_hash              fg=70,bold
-ble-face -s varname_number            fg=64

-ble-face -s varname_transform         fg=29,bold
-ble-face -s varname_unset             fg=124
-ble-face -s argument_option           fg=teal
-ble-face -s argument_error            fg=black,bg=225
-```
-
-現在の描画設定の一覧は以下のコマンドでも確認できます (`ble-face` を無引数で呼び出す)。
-```console
-$ ble-face
-```
-
-色コードはシェル関数 `ble-color-show` (`ble.sh` 内で定義) で確認できます。
-```console
-$ ble-color-show
-```
-
-## 2.7 キーバインディング
-
-キーバインディングはシェル関数 `ble-bind` を使って変更できます。
-例えば <kbd>C-x h</kbd> を入力した時に "Hello, world!" と挿入させたければ以下のようにします。
-```bash
-ble-bind -f 'C-x h' 'insert-string "Hello, world!"'
-```
-
-<kbd>M-c</kbd> を入力した時にコマンドを実行するには以下のようにします。
-
-```bash
-ble-bind -c 'M-c' 'my-command'
-```
-
-<kbd>C-r</kbd> を入力した時に、ユーザー定義編集関数 (Bash の `bind -x` で指定するのと同様の物) を実行するには以下のようにします。
-
-```bash
-ble-bind -x 'C-r' 'my-edit-function'
-```
-
-既存のキーバインディングは以下のコマンドで確認できます。
-```console
-$ ble-bind -P
-```
-
-以下のコマンドでキーバインディングに使える編集関数一覧を確認できます。
-```console
-$ ble-bind -L
-```
-
-一つのキーで複数の編集関数を呼び出したい場合は、以下の例の様に、
-`ble/widget/編集関数の名前` という名前のシェル関数を通して新しい編集関数を定義できます。
-既存の標準の編集関数と名前が重複しない様に、
-編集関数の名前は `ユーザー名/`, `my/`, `blerc/`, `dotfiles/` などで始める事が強く推奨されます。
-
-```bash
-# C-t で複数の操作を行う例
-function ble/widget/my/example1 {
-  ble/widget/beginning-of-logical-line
-  ble/widget/insert-string 'echo $('
-  ble/widget/end-of-logical-line
-  ble/widget/insert-string ')'
-}
-ble-bind -f C-t my/example1
-```
-
-# 3 ヒント
-
-## 3.1 複数行モード
-
-コマンドラインに改行が含まれている場合、複数行モード (MULTILINE モード) になります。
-
-<kbd>C-v C-j</kbd> または <kbd>C-q C-j</kbd> とすると改行をコマンドラインの一部として入力できます。
-複数行モードでは、<kbd>RET</kbd> (<kbd>C-m</kbd>) はコマンドの実行ではなく新しい改行の挿入になります。
-複数行モードでは、<kbd>C-j</kbd> を用いてコマンドを実行して下さい。
-
-`shopt -s cmdhist` が設定されているとき (既定)、もし <kbd>RET</kbd> (<kbd>C-m</kbd>) を押した時にコマンドラインが構文的に閉じていなければ、コマンドの実行ではなく改行の挿入を行います。
-
-## 3.2 Vim モード
-
-`.bashrc` に `set -o vi` が設定されているとき、または `.inputrc` に `set editing-mode vi` が設定されているとき、vim モードが有効になります。
-Vim モードの詳細な設定については [Wiki のページ (英語)](https://github.com/akinomyoga/ble.sh/wiki/Vi-(Vim)-editing-mode) を御覧ください。
-
-## 3.3 自動補完
-
-Bash 4.0 以降では自動補完が有効になり、予測候補が表示されます。
-候補を確定するには <kbd>S-RET</kbd> を入力します (編集文字列の末尾にいる時は <kbd>right</kbd>, <kbd>C-f</kbd> または <kbd>end</kbd> でも確定できます)。
-表示されている候補の初めの単語だけ部分的に確定する時は <kbd>M-f</kbd> または <kbd>M-right</kbd> を入力します。
-現在の候補で確定しそのままコマンドを実行する場合には <kbd>C-RET</kbd> (※お使いの端末が対応している時) を入力します。
-
-## 3.4 静的略語展開
-
-特定の単語を静的略語展開に登録することで好きな文字列に展開することができます。
-登録済み単語に一致する単語の直後で <kbd>SP</kbd> を入力した時に静的略語展開が起きます。
-例えば、以下の設定をしておくと `command L` まで入力した状態で <kbd>SP</kbd> を押した時に、コマンドラインが `command | less` に展開されます。
-
-```bash
-# blerc
-ble-sabbrev L='| less'
-```
-
-実際に実行したいコマンドに含まれる可能性の低い単語として、`\` で始まる単語を静的略語展開に登録することもお薦めです。
-
-```bash
-# blerc
-ble-sabbrev '\L'='| less'
-```

-
-*Bash Line Editor* (`ble.sh`) is a command line editor written in pure Bash which replaces the default GNU Readline.
-
-Current devel version is 0.4.
-This script supports Bash 3.0 or higher although we recommend to use `ble.sh` with release versions of Bash 4.0 or higher.
-Currently, only `UTF-8` encoding is supported for non-ASCII characters.
-This script is provided under the [**BSD License**](LICENSE.md) (3-clause BSD license).
-
-Disclaimer: The core part of the line editor is written in **pure Bash**, but
-`ble.sh` relies on POSIX `stty` to set up TTY states before and after the execution of user commands.
-It also uses other POSIX utilities for acceleration
-in some part of initialization and cleanup code,
-processing of large data in completions, paste of large data, etc.
-
-Pronunciation: The easiest pronunciation of `ble.sh` that users use is /blɛʃ/, but you can actually pronounce it as you like.
-I do not specify the canonical way of pronoucing `ble.sh`.
-In fact, I personally read it verbosely as /biːɛliː dɑt ɛseɪtʃ/ in my head.
-
-## Quick instructions
-
-Installation requires the commands `git`, `make` (GNU make), and `gawk` (in addition to `bash` and POSIX standard utilities).
-For detailed descriptions, see [Sec 1.1](#get-from-source) and [Sec 1.2](#get-from-tarball) for trial/installation,
-[Sec 1.3](#set-up-bashrc) for the setup of your `~/.bashrc`.
-Please replace `make` with `gmake` if your system provides GNU make as `gmake` (such as in BSD).
-
-```bash
-# TRIAL without installation
-
-git clone --recursive https://github.com/akinomyoga/ble.sh.git
-make -C ble.sh
-source ble.sh/out/ble.sh
-
-# Quick INSTALL to BASHRC (If this doesn't work, please follow Sec 1.3)
-
-git clone --recursive https://github.com/akinomyoga/ble.sh.git
-make -C ble.sh install PREFIX=~/.local
-echo 'source ~/.local/share/blesh/ble.sh' >> ~/.bashrc

-make -C ble.sh install DESTDIR=/tmp/blesh-package PREFIX=/usr/local
-```
-
-You may also install `ble.sh` through package-management systems (currently only AUR):
-
-- [AUR (Arch Linux)](https://github.com/akinomyoga/ble.sh/wiki/Manual-A1-Installation#user-content-AUR) `blesh-git` (devel), `blesh` (stable 0.3.3)
-
-## Features
-
-- **Syntax highlighting**: Highlight command lines input by users as in `fish` and `zsh-syntax-highlighting`.
-  Unlike the simple highlighting in `zsh-syntax-highlighting`, `ble.sh` performs syntactic analysis
-  to enable the correct highlighting of complex structures such as nested command substitutions, multiple here documents, etc.
-  Highlighting colors and styles are [fully configurable](https://github.com/akinomyoga/ble.sh/wiki/Manual-%C2%A72-Graphics).
-- **Enhanced completion**:
-  Extend [completion](https://github.com/akinomyoga/ble.sh/wiki/Manual-%C2%A77-Completion)
-  by **syntax-aware completion**, completion with quotes and parameter expansions in prefix texts, **ambiguous candidate generation**, etc.
-  Also, [**menu-complete**](https://github.com/akinomyoga/ble.sh/wiki/Manual-%C2%A77-Completion#user-content-sec-menu-complete)
-  supports selection of candidates in menu (candidate list) by cursor keys, <kbd>TAB</kbd> and <kbd>S-TAB</kbd>.
-  The feature [**auto-complete**](https://github.com/akinomyoga/ble.sh/wiki/Manual-%C2%A77-Completion#user-content-sec-auto-complete)
-  supports the automatic suggestion of completed texts as in `fish` and `zsh-autosuggestions` (with Bash 4.0+).
-  The feature [**menu-filter**](https://github.com/akinomyoga/ble.sh/wiki/Manual-%C2%A77-Completion#user-content-sec-menu-filter)
-  integrates automatic filtering of candidates into menu completion (with Bash 4.0+).
-  There are other functionalities such as
-  [**dabbrev**](https://github.com/akinomyoga/ble.sh/wiki/Manual-%C2%A77-Completion#user-content-sec-dabbrev) and
-  [**sabbrev**](https://github.com/akinomyoga/ble.sh/wiki/Manual-%C2%A77-Completion#user-content-sec-sabbrev) like
-  [*zsh abbreviations*](https://unix.stackexchange.com/questions/6152/zsh-alias-expansion) or [`zsh-abbr`](https://github.com/olets/zsh-abbr).
-- **Vim editing mode**: Enhance `readline`'s vi editing mode available with `set -o vi`.
-  Vim editing mode supports various vim modes such as char/line/block visual/select mode, replace mode,
-  command mode, operator pending mode as well as insert mode and normal mode.
-  Vim editing mode supports various operators, text objects, registers, keyboard macros, marks, etc.
-  It also provides `vim-surround` as an option.
-- Other interesting features include
-  [**status line**](https://github.com/akinomyoga/ble.sh/wiki/Manual-%C2%A74-Editing#user-content-bleopt-prompt_status_line),
-  [**history share**](https://github.com/akinomyoga/ble.sh/wiki/Manual-%C2%A74-Editing#user-content-bleopt-history_share),
-  [**right prompt**](https://github.com/akinomyoga/ble.sh/wiki/Manual-%C2%A74-Editing#user-content-bleopt-prompt_rps1),
-  [**transient prompt**](https://github.com/akinomyoga/ble.sh/wiki/Manual-%C2%A74-Editing#user-content-bleopt-prompt_ps1_transient),
-  [**xterm title**](https://github.com/akinomyoga/ble.sh/wiki/Manual-%C2%A74-Editing#user-content-bleopt-prompt_xterm_title), etc.
-
-Note: ble.sh does not provide specific settings of the prompt, aliases, functions, etc.
-ble.sh provides a more fundamental infrastructure so that users can set up their own prompt, aliases, functions, etc.
-Of course ble.sh can be used in combination with other Bash configurations such as [`bash-it`](https://github.com/Bash-it/bash-it) and [`oh-my-bash`](https://github.com/ohmybash/oh-my-bash).

-## History and roadmap
-
-My little experiment has took place in one corner of my `bashrc` in the end of May, 2013 after I enjoyed some article on `zsh-syntax-highlighting`.
-I initially thought something can be achieved by writing a few hundred of lines of codes
-but soon realized that everything needs to be re-implemented for the authentic support of syntax highlighting in Bash.
-I decided to make it as an independent script `ble.sh`.
-The name stemmed from that of Zsh's line editor, *ZLE* (*Zsh Line Editor*), but suffixed with `.sh` for the implication of being written in shell script.
-I'm occasinally asked about the pronunciation of `ble.sh`, but you can actually pronounce it as you like.
-After the two-week experiment, I was satisfied with my conclusion that it is *possible* to implement a full-featured line editor in Bash that satisfies the actual daily uses.
-The real efforts of improving the prototype implementation for the real uses was started in Feburuary, 2015.
-I released the initial version in the next December. Until then, the basic part of the line editor was completed.
-The implementation of vim mode has been started in September, 2017 and completed in the next March.
-I started working on the enhancement of the completion in August, 2018 and released it in the next February.

-# 1 Usage
-
-## 1.1 Try `ble.sh` generated from source (version ble-0.4 devel)<sup><a id="get-from-source" href="#get-from-source">†</a></sup>
-
-### Generate
-
-To generate `ble.sh`, `gawk` (GNU awk) and `gmake` (GNU make) (in addition to Bash and POSIX standard utilities) is required.
-The file `ble.sh` can be generated using the following commands.
-If you have GNU make installed on `gmake`, please use `gmake` instead of `make`.
-```bash
-git clone --recursive https://github.com/akinomyoga/ble.sh.git
-cd ble.sh
-make
-```
-
-A script file `ble.sh` will be generated in the directory `ble.sh/out`.
-
-### Try
-
-Then, you can load `ble.sh` in the Bash session using the `source` command:
-```bash
-source out/ble.sh
-```
-
-### Install
-
-To install `ble.sh` in a specified directory, use `make install`.
-
-```bash
-# INSTALL to ~/.local/share/blesh
-make install
-
-# INSTALL to a specified directory
-make install INSDIR=/path/to/blesh
-
-# PACKAGE (for package maintainers)
-make install DESTDIR=/tmp/blesh-package PREFIX=/usr/local
-```
-
-If either the make variables `DESTDIR` or `PREFIX` is supplied, `ble.sh` will be copied to `$DESTDIR/$PREFIX/share/blesh`.
-Otherwise, if the make variables `INSDIR` is specified, it will be installed directly on `$INSDIR`.
-Otherwise, if the environment variable `$XDG_DATA_HOME` is defined, the install location will be `$XDG_DATA_HOME/blesh`.
-If none of these variables are specified, the default install location is `~/.local/share/blesh`.
-
-To set up `.bashrc` see [Sec. 1.3](#set-up-bashrc).
-
-## 1.2 Or, use a tar ball of `ble.sh` obtained from GitHub releases<sup><a id="get-from-tarball" href="#get-from-tarball">†</a></sup>
-
-For download, trial and install, see the description at each release page.
-The stable versions are significantly old compared to the devel version, so many features are unavailable.
-
-- Devel [v0.4.0-devel2](https://github.com/akinomyoga/ble.sh/releases/tag/v0.4.0-devel2) (2020-12)
-- Stable [v0.3.3](https://github.com/akinomyoga/ble.sh/releases/tag/v0.3.3) (2019-02 fork) Enhanced completions
-- Stable [v0.2.6](https://github.com/akinomyoga/ble.sh/releases/tag/v0.2.6) (2018-03 fork) Vim mode
-- Stable [v0.1.14](https://github.com/akinomyoga/ble.sh/releases/tag/v0.1.14) (2015-12 fork) Syntax highlighting
-
-## 1.3 Set up `.bashrc`<sup><a id="set-up-bashrc" href="#set-up-bashrc">†</a></sup>
-
-If you want to load `ble.sh` by default in interactive sessions of `bash`, usually one can just source `ble.sh` in `~/.bashrc`,
-but more reliable way is to add the following codes to your `.bashrc` file:
-```bash
-# bashrc
-
-# Add this lines at the top of .bashrc:
-[[ $- == *i* ]] && source /path/to/blesh/ble.sh --noattach
-
-# your bashrc settings come here...
-
-# Add this line at the end of .bashrc:
-[[ ${BLE_VERSION-} ]] && ble-attach
-```
-
-## 1.4 User settings `~/.blerc`
-
-User settings can be placed in the init script `~/.blerc` (or `${XDG_CONFIG_HOME:-$HOME/.config}/blesh/init.sh` if `~/.blerc` is not available)
-whose template is available as the file [`blerc`](https://github.com/akinomyoga/ble.sh/blob/master/blerc) in the repository.
-The init script is a Bash script which will be sourced during the load of `ble.sh`, so any shell commands can be used in `~/.blerc`.
-If you want to change the default path of the init script, you can add the option `--rcfile INITFILE` to `source ble.sh` as the following example:
-
-```bash
-# in bashrc
-
-# Example 1: ~/.blerc will be used by default
-[[ $- == *i* ]] && source /path/to/blesh/ble.sh --noattach
-
-# Example 2: /path/to/your/blerc will be used
-[[ $- == *i* ]] && source /path/to/blesh/ble.sh --noattach --rcfile /path/to/your/blerc
-```
-
-## 1.5 Update
-
-You need Git (`git`), GNU awk (`gawk`) and GNU make (`make`).
-For `ble-0.3+`, you can run `ble-update` in the session with `ble.sh` loaded:
-
-```bash
-$ ble-update
-```
-
-For `ble.0.4+`, you can also update it outside the `ble.sh` session using
-
-```bash
-$ bash /path/to/ble.sh --update
-```
-
-You can instead download the latest version by `git pull` and install it:
-
-```bash
-cd ble.sh   # <-- enter the git repository you already have
-git pull
-git submodule update --recursive --remote
-make
-make INSDIR="$HOME/.local/share/blesh" install
-```
-
-## 1.6 Uninstall
-
-Basically you can simply delete the installed directory and the settings that user added.
-
-- Close all the `ble.sh` sessions (the Bash interactive sessions with `ble.sh`)
-- Remove the added lines in `.bashrc`.
-- Remove `blerc` files (`~/.blerc` or `~/.config/blesh/init.sh`) if any.
-- Remove the installed directory.
-- Remove the cache directory `~/.cache/blesh` if any.
-- Remove the temporary directory `/tmp/blesh` if any [ Only needed when your system does not automatically clears `/tmp` ].
-
-# 2 Basic settings

-
-## 2.1 Vim mode
-
-For the vi/vim mode, check [the wiki page](https://github.com/akinomyoga/ble.sh/wiki/Vi-(Vim)-editing-mode).
-
-## 2.2 Disable features
-
-One of frequently asked questions is the way to disable a specific feature that `ble.sh` adds.
-Here the settings for disabling features are summarized.
-
-```bash
-# Disable syntax highlighting
-bleopt highlight_syntax=
-
-# Disable highlighting based on filenames
-bleopt highlight_filename=
-
-# Disable highlighting based on variable types
-bleopt highlight_variable=
-
-# Disable auto-complete (Note: auto-complete is enabled by default in bash-4.0+)
-bleopt complete_auto_complete=
-# Tip: you may instead specify the delay of auto-complete in millisecond
-bleopt complete_auto_delay=300
-
-# Disable auto-complete based on the command history
-bleopt complete_auto_history=
-
-# Disable ambiguous completion
-bleopt complete_ambiguous=
-
-# Disable menu-complete by TAB
-bleopt complete_menu_complete=
-
-# Disable menu filtering (Note: auto-complete is enabled by default in bash-4.0+)
-bleopt complete_menu_filter=
-
-# Disable EOF marker like "[ble: EOF]"
-bleopt prompt_eol_mark=''
-# Tip: you may instead specify another string:
-bleopt prompt_eol_mark='⏎'
-
-# Disable error exit marker like "[ble: exit %d]"
-bleopt exec_errexit_mark=
-# Tip: you may instead specify another string:
-bleopt exec_errexit_mark=$'\e[91m[error %d]\e[m'
-
-# Disable elapsed-time marker like "[ble: elapsed 1.203s (CPU 0.4%)]"
-bleopt exec_elapsed_mark=
-# Tip: you may instead specify another string
-bleopt exec_elapsed_mark=$'\e[94m[%ss (%s %%)]\e[m'
-# Tip: you may instead change the threshold of showing the mark
-bleopt exec_elapsed_enabled='sys+usr>=10*60*1000' # e.g. ten minutes for total CPU usage
-```
-
-## 2.3 CJK Width
-
-The option `char_width_mode` controls the width of the Unicode characters with `East_Asian_Width=A` (Ambiguous characters).
-Currently four values `emacs`, `west`, `east`, and `auto` are supported. With the value `emacs`, the default width in emacs is used.
-With `west` all the ambiguous characters have width 1 (Hankaku). With `east` all the ambiguous characters have width 2 (Zenkaku).
-With `auto` the width mode `west` or `east` is automatically chosen based on the terminal behavior.
-The default value is `auto`. Appropriate value should be chosen in accordance with your terminal behavior.
-For example, the value can be changed to `west` as:
-
-```bash
-bleopt char_width_mode='west'
-```
-
-## 2.4 Input Encoding
-
-The option `input_encoding` controls the encoding scheme used in the decode of input. Currently `UTF-8` and `C` are available. With the value `C`, byte values are directly interpreted as character codes. The default value is `UTF-8`. For example, the value can be changed to `C` as:
-
-```bash
-bleopt input_encoding='C'
-```
-
-## 2.5 Bell
-
-The options `edit_abell` and `edit_vbell` control the behavior of the edit function `bell`. If `edit_abell` is a non-empty string, audible bell is enabled, i.e. ASCII Control Character `BEL` (0x07) will be written to `stderr`. If `edit_vbell` is a non-empty string, visual bell is enabled. By default, the audible bell is enabled while the visual bell is disabled.
-
-The option `vbell_default_message` specifies the message shown as the visual bell. The default value is `' Wuff, -- Wuff!! '`. The option `vbell_duration` specifies the display duration of the visual-bell message. The unit is millisecond. The default value is `2000`.
-
-For example, the visual bell can be enabled as:
-```
-bleopt edit_vbell=1 vbell_default_message=' BEL ' vbell_duration=3000
-```
-
-For another instance, the audible bell is disabled as:
-```
-bleopt edit_abell=
-```
-
-## 2.6 Highlight Colors
-
-The colors and attributes used in the syntax highlighting are controlled by `ble-face` function. The following code reproduces the default configuration:
-```bash
-# highlighting related to editing
-ble-face -s region                    bg=60,fg=white
-ble-face -s region_target             bg=153,fg=black

-ble-face -s argument_option           fg=teal
-ble-face -s argument_error            fg=black,bg=225
-
-```
-
-The current list of faces can be obtained by the following command (`ble-face` without arguments):
-```console
-$ ble-face
-```
-
-The color codes can be checked in output of the function `ble-color-show` (defined in `ble.sh`):
-```console
-$ ble-color-show
-```
-
-## 2.7 Key Bindings
-
-Key bindings can be controlled with the shell function, `ble-bind`.
-For example, with the following setting, "Hello, world!" will be inserted on typing <kbd>C-x h</kbd>
-```bash
-ble-bind -f 'C-x h' 'insert-string "Hello, world!"'
-```
-
-For another example, if you want to invoke a command on typing <kbd>M-c</kbd>, you can write as follows:
-
-```bash
-ble-bind -c 'M-c' 'my-command'
-```
-
-Or, if you want to invoke a edit function (designed for Bash `bind -x`) on typing <kbd>C-r</kbd>, you can write as follows:
-
-```bash
-ble-bind -x 'C-r' 'my-edit-function'
-```
-
-The existing key bindings are shown by the following command:
-```console
-$ ble-bind -P
-```
-
-The list of widgets is shown by the following command:
-```console
-$ ble-bind -L
-```
-
-If you want to run multiple widgets with a key, you can define your own widget by creating a function of the name `ble/widget/YOUR_WIDGET_NAME`
-as illustrated in the following example.
-It is highly recommended to prefix the widget name with `YOUR_NAME/`, `my/`, `blerc/`, `dotfiles/`, etc.
-in order not to conflict with the names of the existing standard widgets.
-
-```bash
-# Example of calling multiple widgets with the key C-t
-function ble/widget/my/example1 {
-  ble/widget/beginning-of-logical-line
-  ble/widget/insert-string 'echo $('
-  ble/widget/end-of-logical-line
-  ble/widget/insert-string ')'
-}
-ble-bind -f C-t my/example1
-```
-
-# 3 Tips
-
-## 3.1 Use multiline mode
-
-When the command line string contains a newline character, `ble.sh` enters the MULTILINE mode.
-
-By typing <kbd>C-v C-j</kbd> or <kbd>C-q C-j</kbd>, you can insert a newline character in the command line string.
-In the MULTILINE mode, <kbd>RET</kbd> (<kbd>C-m</kbd>) causes insertion of a new newline character.
-In the MULTILINE mode, the command can be executed by typing <kbd>C-j</kbd>.
-
-When the shell option `shopt -s cmdhist` is set (which is the default),
-<kbd>RET</kbd> (<kbd>C-m</kbd>) inserts a newline if the current command line string is syntactically incomplete.
-
-## 3.2 Use vim editing mode
-
-If `set -o vi` is specified in `.bashrc` or `set editing-mode vi` is specified in `.inputrc`, the vim mode is enabled.
-For details, please check [the wiki page](https://github.com/akinomyoga/ble.sh/wiki/Vi-(Vim)-editing-mode).
-
-## 3.3 Use `auto-complete`
-
-The feature `auto-complete` is available in Bash 4.0 or later. `auto-complete` automatically suggests a possible completion on user input.
-The suggested contents can be inserted by typing <kbd>S-RET</kbd>
-(when the cursor is at the end of the command line, you can also use <kbd>right</kbd>, <kbd>C-f</kbd> or <kbd>end</kbd> to insert the suggestion).
-If you want to insert only first word of the suggested contents, you can use <kbd>M-right</kbd> or <kbd>M-f</kbd>.
-If you want to accept the suggestion and immediately run the command, you can use <kbd>C-RET</kbd> (if your terminal supports this special key combination).
-
-## 3.4 Use `sabbrev` (static abbrev expansions)
-
-By registering words to `sabbrev`, the words can be expanded to predefined strings.
-When the cursor is just after a registered word, typing <kbd>SP</kbd> causes `sabbrev` expansion.
-For example, with the following settings, when you type <kbd>SP</kbd> after the string `command L`, the command line will be expanded to `command | less`.
-
-```bash
-# blerc
-ble-sabbrev L='| less'

-
-### 選択肢その2: `~/.blerc`内で設定する
-
-別の方法として，`blerc`において次のように直接設定を書くこともできます（`/path/to/fzf`は各人のfzfへのパスに置き換えてください）。
-この場合，`.fzf.bash`を`.bashrc`の中で呼び出さ（`source`コマンドを用い）ないでください。
-
-```bash
-# blerc
-
-# fzfの設定
-_ble_contrib_fzf_base=/path/to/fzf
-ble-import -d contrib/fzf-completion
-ble-import -d contrib/fzf-key-bindings
-```
-
-## :pencil: fzf-git
-
-[fzf-git](https://gist.github.com/junegunn/8b572b8d4b5eddd8b85e5f4d40f17236)での設定を`ble.sh`と共に用いるには，次のように設定してください。
-
-```bash
-# bashrc / fzf.bash
-if [[ ${BLE_VERSION-} ]]; then
-  _ble_contrib_fzf_base=/path/to/fzf
-  _ble_contrib_fzf_git_config=key-binding:sabbrev:arpeggio
-  ble-import -d contrib/fzf-git
-fi
-```
-
-または，`~/.blerc`内でも構成できます:
-
-```bash
-# blerc
-_ble_contrib_fzf_base=/path/to/fzf
-_ble_contrib_fzf_git_config=key-binding:sabbrev:arpeggio
-ble-import -d contrib/fzf-git
-```
-
-シェル変数`$_ble_contrib_fzf_git_config`には，有効にする束縛の種別をコロン区切りで列挙します。
-`key-binding`という値で，次の形式のキー束縛を有効にします: <kbd>C-g C-f</kbd>, <kbd>C-g C-b</kbd>, <kbd>C-g C-t</kbd>, <kbd>C-g C-h</kbd>及び<kbd>C-g C-r</kbd>。
-`sabbrev`という値で，次の語に対する静的略語展開を有効にします: `gf`, `gb`, `gt`, `gh`及び`gr`。
-`arpeggio`という値で，次のキーの組み合わせを同時に押下できるようにします: <kbd>g f</kbd>, <kbd>g b</kbd>, <kbd>g t</kbd>, <kbd>g h</kbd>及び<kbd>g r</kbd>。

-## :pencil: プロンプトにおける特殊指定
-
-### `\q{contrib/vim-mode}`
-
-この指定はVimのモード名に展開されます。 
-
-```bash
-# blerc（例）
-ble-import contrib/prompt-vim-mode
-PS1='[\u@\h \W]\q{contrib/vim-mode}\$ ' # PS1にモード名を表示
-bleopt keymap_vi_mode_show:=            # モード行を表示しない

-## :pencil: fzf integration
-
-Source: [`fzf-completion.bash`](https://github.com/akinomyoga/blesh-contrib/blob/master/fzf-completion.bash),
-  [`fzf-key-bindings.bash`](https://github.com/akinomyoga/blesh-contrib/blob/master/fzf-key-bindings.bash)
-
-Note: If you would like to integrate `fzf-completion` with `bash-completion`, `bash-completion` needs to be loaded before `fzf-completion` is loaded.
-
-### Option 1: Setup in `~/.fzf.bash`
-
-If you would like to use fzf with `ble.sh`, you can rewrite your `.fzf.bash` in the following way (please replace `/path/to/fzf` by your fzf path, the path to the **fzf directory** but not the fzf binary):
-
-```bash
-# fzf.bash
-
-# Setup fzf
-# ---------
-_ble_contrib_fzf_base=/path/to/fzf
-if [[ ! "$PATH" == *"$_ble_contrib_fzf_base/bin"* ]]; then
-  export PATH="${PATH:+${PATH}:}/path/to/fzf/bin"
-fi
-
-# Auto-completion
-# ---------------
-if [[ ${BLE_VERSION-} ]]; then
-  ble-import -d contrib/fzf-completion
-else
-  [[ $- == *i* ]] && source "$_ble_contrib_fzf_base/shell/completion.bash" 2> /dev/null
-fi
-
-# Key bindings
-# ------------
-if [[ ${BLE_VERSION-} ]]; then
-  ble-import -d contrib/fzf-key-bindings
-else
-  source "$_ble_contrib_fzf_base/shell/key-bindings.bash"
-fi
-```
-
-### Option 2: Setup in `~/.blerc`
-
-Or, you can directly write settings in your `blerc` as follows (please replace `/path/to/fzf` by your fzf path).
-In this case do not source `.fzf.bash` in your `.bashrc`.
-
-```bash
-# blerc
-
-# Setup fzf
-_ble_contrib_fzf_base=/path/to/fzf
-ble-import -d contrib/fzf-completion
-ble-import -d contrib/fzf-key-bindings
-```
-
-## :pencil: `contrib/fzf-git`
-
-Source: [`fzf-git.bash`](https://github.com/akinomyoga/blesh-contrib/blob/master/fzf-git.bash)
-
-You can use [fzf-git](https://gist.github.com/junegunn/8b572b8d4b5eddd8b85e5f4d40f17236) settings for `ble.sh` with the following settings.
-
-```bash
-# bashrc / fzf.bash
-if [[ ${BLE_VERSION-} ]]; then
-  _ble_contrib_fzf_base=/path/to/fzf
-  _ble_contrib_fzf_git_config=key-binding:sabbrev:arpeggio
-  ble-import -d contrib/fzf-git
-fi
-```
-
-Or you can configure it in `~/.blerc`:
-
-```bash
-# blerc
-_ble_contrib_fzf_base=/path/to/fzf
-_ble_contrib_fzf_git_config=key-binding:sabbrev:arpeggio
-ble-import -d contrib/fzf-git
-```
-
-The shell variable `_ble_contrib_fzf_git_config` is a colon-separated list of the enabled types of bindings.
-The value `key-binding` enables the key bindings of the form <kbd>C-g C-f</kbd>, <kbd>C-g C-b</kbd>, <kbd>C-g C-t</kbd>, <kbd>C-g C-h</kbd> and <kbd>C-g C-r</kbd>.
-The value `sabbrev` enables the sabbrev expansion for the words `gf`, `gb`, `gt`, `gh` and `gr`.
-The value `arpeggio` enables the simultaneous key combinations of <kbd>g f</kbd>, <kbd>g b</kbd>, <kbd>g t</kbd>, <kbd>g h</kbd> and <kbd>g r</kbd>.

-
-## :pencil: `contrib/prompt-vim-mode`
-
-Source: [`prompt-vim-mode.bash`](https://github.com/akinomyoga/blesh-contrib/blob/master/prompt-vim-mode.bash)
-
-### `\q{contrib/vim-mode}`
-
-This prompt sequence expands to the vim mode name.
-
-```bash
-# blerc (example)

-
-```bash
-# blerc (example)
-
-ble-import contrib/prompt-git
-bleopt prompt_rps1='\q{contrib/git-info}'
-```
-
-### `\q{contrib/git-info}`
-
-This expands to a string that explains the current git status.
-
-### `\q{contrib/git-name}`
-
-This expands to the directory name of the repository.
-
-### `\q{contrib/git-hash N}`
-
-This expands to the commit hash.
-The hash is truncated to the length `N`.
-The default value for `N` is `7`.
-
-### `\q{contrib/git-branch}`
-
-This expands to the branch name (or tag name or hash) of `HEAD`.
-
-### `\q{contrib/git-path}`
-
-This expands to the current path relative to the root directory of the repository.
-
-## :pencil: `contrib/prompt-elapsed`
-
-Source: [`prompt-elapsed.bash`](https://github.com/akinomyoga/blesh-contrib/blob/master/prompt-elapsed.bash)
-
-Measures the time of the previous command execution.
-
-```bash
-# blerc (example)
-
-ble-import contrib/prompt-elapsed
-bleopt prompt_rps1='\g{fg=69,italic}\q{contrib/elapsed}'
-```
-
-### `\q{contrib/elapsed}`
-
-This expands to the high-resolution elapsed time for the command execution.
-
-### `\q{contrib/elapsed-real}`
-
-This expands to the `real` time of `time`.
-
-### `\q{contrib/elapsed-user}`
-
