如何在windows上改善babun zsh的加載時間？

Question

我喜歡ZSH shell及其主題，但它非常慢。 加載需要7到10秒。 我也將它用作VS Code中的集成終端，即使加載速度很慢。 這是我的.zshrc文件的副本。

# Path to your oh-my-zsh installation.
export ZSH=$HOME/.oh-my-zsh
export PS1="[%* - %D] %d %% "


# Set name of the theme to load. 
# Look in ~/.oh-my-zsh/themes/
# Optionally, if you set this to "random", it'll load a random theme each
# time that oh-my-zsh is loaded.
ZSH_THEME="agnoster"
DEFAULT_USER=13000

# Uncomment the following line to use case-sensitive completion.
# CASE_SENSITIVE="true"

# Uncomment the following line to use hyphen-insensitive completion. Case
# sensitive completion must be off. _ and - will be interchangeable.
# HYPHEN_INSENSITIVE="true"

# Uncomment the following line to disable bi-weekly auto-update checks.
# DISABLE_AUTO_UPDATE="true"

# Uncomment the following line to change how often to auto-update (in days).
# export UPDATE_ZSH_DAYS=13

# Uncomment the following line to disable colors in ls.
# DISABLE_LS_COLORS="true"

# Uncomment the following line to disable auto-setting terminal title.
# DISABLE_AUTO_TITLE="true"

# Uncomment the following line to enable command auto-correction.
# ENABLE_CORRECTION="true"

# Uncomment the following line to display red dots whilst waiting for 
  completion.
# COMPLETION_WAITING_DOTS="true"

# Uncomment the following line if you want to disable marking untracked 
  files
# under VCS as dirty. This makes repository status check for large 
  repositories
# much, much faster.
# DISABLE_UNTRACKED_FILES_DIRTY="true"

# Uncomment the following line if you want to change the command execution 
  time
# stamp shown in the history command output.
# The optional three formats: "mm/dd/yyyy"|"dd.mm.yyyy"|"yyyy-mm-dd"
# HIST_STAMPS="mm/dd/yyyy"

# Would you like to use another custom folder than $ZSH/custom?
# ZSH_CUSTOM=/path/to/new-custom-folder

# Which plugins would you like to load? (plugins can be found in ~/.oh-my-
  zsh/plugins/*)
# Custom plugins may be added to ~/.oh-my-zsh/custom/plugins/
# Example format: plugins=(rails git textmate ruby lighthouse)
# Add wisely, as too many plugins slow down shell startup.
  plugins=(git)

# User configuration

export PATH=$HOME/bin:/usr/local/bin:$PATH
# export MANPATH="/usr/local/man:$MANPATH"

source $ZSH/oh-my-zsh.sh


# You may need to manually set your language environment
# export LANG=en_US.UTF-8

# if [[ -n $SSH_CONNECTION ]]; then
#   export EDITOR='vim'
# else
#   export EDITOR='mvim'
# fi

# Compilation flags
# export ARCHFLAGS="-arch x86_64"

# ssh
# export SSH_KEY_PATH="~/.ssh/dsa_id"

# Set personal aliases, overriding those provided by oh-my-zsh libs,
# plugins, and themes. Aliases can be placed here, though oh-my-zsh
# users are encouraged to define aliases within the ZSH_CUSTOM folder.
# For a full list of active aliases, run `alias`.
#
# Example aliases
# alias zshconfig="mate ~/.zshrc"
# alias ohmyzsh="mate ~/.oh-my-zsh"

  prompt_segment blue black "${PWD##*/}"

不要介意長篇帖子：D。

Answer 1

我在我的Windows 10機器上安裝了babun。

禁用bash自動完成作業會略微改善我的加載時間。 我將所有文件重命名為“bash_completion.d”目錄中的“.bk”擴展名。

{ ~ }  » ls -ltr /etc/bash_completion.d                                                         ~
total 68
-rwxrwx---+ 1 m.ortiz.montealegre Domain Users   998 Jun 23  2015 vim-completion.bk
-rwxrwx---+ 1 m.ortiz.montealegre Domain Users 44924 Jun 23  2015 svn.bk
-rwxrwx---+ 1 m.ortiz.montealegre Domain Users  1200 Jun 23  2015 gvim-completion.bk
-rwxrwx---+ 1 m.ortiz.montealegre Domain Users  2609 Jun 23  2015 gsettings.bk
-rwxrwx---+ 1 m.ortiz.montealegre Domain Users  1356 Jun 23  2015 gresource.bk

-rwxrwx---+ 1 m.ortiz.montealegre Domain Users  1389 Jun 23  2015 gapplication.bk

調試是一個很好的選擇，有了strace，看看Cygwin加載時發生了什么，請檢查這個問題 。

關於Babun調整

你可以用來檢查你的安裝的工具記錄在babun網站上，使用babun check也許這提供了一些線索：

{ ~ } » babun check                                                                          ~
Executing babun check
Prompt speed      [SLOW]
Hint: your prompt is very slow. Check the installed 'BLODA' software.
Connection check  [OK]
Update check      [OK]
Cygwin check      [OK]

我不知道你是否在你的babun安裝中進行了一些調整，請檢查你的〜/ .babunrc文件並確認你已經禁用了自動更新和啟動檢查（不要啟用它們）：

# JVM options
export JAVA_OPTS="-Xms128m -Xmx256m"

# Modify these lines to set your locale
export LANG="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"

# Uncomment these lines to the set your machine's default locale (and comment out the UTF-8 ones)
# export LANG=$(locale -uU)
# export LC_CTYPE=$(locale -uU)
# export LC_ALL=$(locale -uU)

# Uncomment this to disable daily auto-update & proxy checks on startup (not recommended!)
# export DISABLE_CHECK_ON_STARTUP="true"

# Uncomment to increase/decrease the check connection timeout
# export CHECK_TIMEOUT_IN_SECS=4

# Uncomment this lines to set up your proxy
# export http_proxy=http://user:password@server:port
# export https_proxy=$http_proxy
# export ftp_proxy=$http_proxy
# export no_proxy=localhost

關於Cygwin

這里有幾個調整，如果你不熟悉Strace，你可以在 這里探索Cygwin。

我認為你應該抽象出“babun”的東西，不要忘記嵌入的Cygwin，我認為你真正想要加速的是，babun核心是一個Cygwin實現，有一些變化：

Babun的核心包括一個預配置的Cygwin。

通常，長加載時間會導致shell使用的框架。

• 你可以試試另一個更小的框架： https ： //github.com/zsh-users/antigen

• 您可以嘗試找出哪些插件/工具在運行時花費最多的時間。

$ zsh -xv將覆蓋運行時加載的內容。 您可以看到哪個插件/進程需要最長的加載和響應時間。

另外你有沒有嘗試清理asl文件？

http://osxdaily.com/2010/05/06/speed-up-a-slow-terminal-by-clearing-log-files/

Answer 3

運行zsh -xv命令並觀看詳細輸出，如看電視（請勿打擾鼠標，按鍵）。 在點上，詳細輸出將變慢，如果可能的話刪除該插件或檢查錯誤。 然后運行source .zshrc 。 再次詳細輸出將開始。 啟動一個新的shell窗口。 你會明白加載變得更快。

我說的是緩慢的Oh-My-ZSH / ZSH部分。 我不是Windows用戶，你應該排除任何與Windows相關的問題。 使用Homebrew，iTerm，這些小問題都是常規問題。 哦，我的ZSH與美麗的東西加載可憐的Mac在插件，主題慢。 沒什么新鮮的。 你可以搜索整個互聯網，你會發現很多Mac用戶和慢哦哦我的ZSH。 您需要在Windows上搜索慢速ZSH或Oh-My-ZSH而不是慢速babun的問題。 使用Oh-My-ZSH的Mac用戶數量要高得多。 此外還有GNU / Linux用戶。

你可以閱讀這篇Github討論和這篇文章 。 所有修復都是為了加快速度。

所有這些都會給你指向泛型的說明，就像我們要說的那樣使DISABLE_AUTO_UPDATE="true"激活，ZSH歷史尺寸變小等等。 跑 ：

cd ~
export HISTSIZE=2000
export HISTFILE="$HOME/.history" 
export SAVEHIST=$HISTSIZE
setopt hist_ignore_all_dups
# reload once
source .zshrc
# check
cat .history
