MSYS2設定ファイルを弄る

MSYS2設定ファイル

HOMEディレクトリにある以下のファイルでいろいろ設定されています。

• .bash_profile : 起動時に一度だけ読み込まれる
• .bashrc : 起動時に一度だけ読み込まれる
• .bash_aliases : alias書くところ
• .bash_function : function書くところ
• etc/fstab,etc/profile : 環境変数書くところ
• .inputrc : キー操作を書くところ

msys2においてaliasの追加、環境変数の追加について書いた記事です。

準備

MSYS2のインストールはこちらから。
MSYS2 installer One click installer for msys2
環境変数をいじっていない人は
C:/User/Program Files/msys64/home以下にあるのではないでしょうか。
linuxっぽく環境変数に'HOME'という名前で、自分のよく使うフォルダを設定しておくとこれからCUIツール使っていく上で何かと都合がよいです。。
僕の場合はHOME=E:/U1and0/Dropbox/Program

# User dependent .bashrc file

# If not running interactively, don't do anything
[[ "$-" != *i* ]] && return

# Shell Options
#
# See man bash for more options...
#
# Don't wait for job termination notification
# set -o notify
#
# Don't use ^D to exit
# set -o ignoreeof
#
# Use case-insensitive filename globbing
# shopt -s nocaseglob
#
# Make bash append rather than overwrite the history on disk
# shopt -s histappend
#
# When changing directory small typos can be ignored by bash
# for example, cd /vr/lgo/apaache would find /var/log/apache
# shopt -s cdspell

# Completion options
#
# These completion tuning parameters change the default behavior of bash_completion:
#
# Define to access remotely checked-out files over passwordless ssh for CVS
# COMP_CVS_REMOTE=1
#
# Define to avoid stripping description in --option=description of './configure --help'
# COMP_CONFIGURE_HINTS=1
#
# Define to avoid flattening internal contents of tar files
# COMP_TAR_INTERNAL_PATHS=1
#
# Uncomment to turn on programmable completion enhancements.
# Any completions you add in ~/.bash_completion are sourced last.
# [[ -f /etc/bash_completion ]] && . /etc/bash_completion

# History Options
#
# Don't put duplicate lines in the history.
# export HISTCONTROL=$HISTCONTROL${HISTCONTROL+,}ignoredups
#
# Ignore some controlling instructions
# HISTIGNORE is a colon-delimited list of patterns which should be excluded.
# The '&' is a special pattern which suppresses duplicate entries.
# export HISTIGNORE=$'[ \t]*:&:[fb]g:exit'
# export HISTIGNORE=$'[ \t]*:&:[fb]g:exit:ls' # Ignore the ls command as well
#
# Whenever displaying the prompt, write the previous line to disk
# export PROMPT_COMMAND="history -a"

# Aliases
#
# Some people use a different file for aliases
# .bash_aliasesを読み込むようにする
if [ -f "${HOME}/.bash_aliases" ]; then
  source "${HOME}/.bash_aliases"
fi
#
# Some example alias instructions
# If these are enabled they will be used instead of any instructions
# they may mask.  For example, alias rm='rm -i' will mask the rm
# application.  To override the alias instruction use a \ before, ie
# \rm will call the real rm not the alias.
#
# Interactive operation...
# alias rm='rm -i'
# alias cp='cp -i'
# alias mv='mv -i'
#
# Default to human readable figures
# alias df='df -h'
# alias du='du -h'
#
# Misc :)
# alias less='less -r'                          # raw control characters
# alias whence='type -a'                        # where, of a sort
# alias grep='grep --color'                     # show differences in colour
# alias egrep='egrep --color=auto'              # show differences in colour
# alias fgrep='fgrep --color=auto'              # show differences in colour
#
# Some shortcuts for different directory listings
# alias ls='ls -hF --color=tty'                 # classify files in colour
# alias dir='ls --color=auto --format=vertical'
# alias vdir='ls --color=auto --format=long'
# alias ll='ls -l'                              # long list
# alias la='ls -A'                              # all but . and ..
# alias l='ls -CF'                              #

# Umask
#
# /etc/profile sets 022, removing write perms to group + others.
# Set a more restrictive umask: i.e. no exec perms for others:
# umask 027
# Paranoid: neither group nor others have any perms:
# umask 077

.bash_profileと.bashrcの使い分け

.bash_profileと.bashrcの使い分けですが、ログイン時に一度設定すればいいものは前者に、bashを起動するたびに設定する必要のあるものは後者にするのが原則です

fstab, profileは環境変数書くところ
場所は/msys64/etc以下に存在する。

マウントはprofileが行う
fstabはwindow形式で書かれたpathをbash形式にしてくれる？ショートカット？(←名称不明)みたいなのを作ってくれる。例を見たほうがいいかも。

例えば以下のように記述する。
半角スペースは区切りに使われるので、ディレクトリにスペースが含まれるC:/Program Files/はC:/Program\040Files/と記述する。
バックスラッシュスラッシュの区別はないみたいだけど一応ディレクトリの区切りはスラッシュにした。

fstab

C:/tools/Anaconda3/Scripts /conda  # C:/tools/Anaconda3/Scriptsを/condaというショートカットで登録
C:/tools/Anaconda3 /Anaconda3  # パスとショートカットの間には半角スペース
C:/Program\040Files/Sublime\040Text\0403 /subl
C:/Program\040Files/gnuplot/bin/ /gnuplot  # \040は半角スペースの意味。

以上をfstabに書き加えたらprofileのORIGINAL_PATHにショートカットを加える。
区切りは':'

MinGW (64bit) + MSYS 環境の構築 (2)

さらに.bash_aliasesにpythonのaliasを追加しておくと、gと打つだけでgit、pyと打つだけでpython、ipyと打つだけでipython開く。

.bash_aliases

alias g='git'
alias py='python'
alias ipy='ipython'

g='git'

$ g

           [--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>]

デフォルトの設定に"\e[1;5C": forward-word # ctrl + rightと"\e[1;5D": backward-word # ctrl + leftを加えた。
ctrl+←(→)でワード単位で移動できる。
なぜデフォルトじゃないんだ。
デフォルトではalt+←(→)でワード単位の移動。
