不使用oh-my-zsh配置轻量级zsh环境

tags: Shell Tips

写在前面

之前一直在用一款名为oh-my-zsh的插件, 在我的MacOS上, 配置起来主题以及各种插件都比较方便, 但是, 最近在archlinux上面, 我用了omz之后, 速度下降了很多(archlinux虚拟机,还是采用架构虚拟化的方式,在arm上模拟出x86_64), 于是我就想着卸载omz然后直接安装代码补全和高亮插件, 这里参考了一篇国外开发者的博客¹, 主要用到的插件是:

• zdharma-zmirror/fast-syntax-highlighting: zdharma mirror of fast-syntax-highlighting (github.com);
• zsh-users/zsh-autosuggestions: Fish-like autosuggestions for zsh (github.com);
• zsh-users/zsh-completions: Additional completion definitions for Zsh. (github.com);

这里原文中还用到了一款主题插件, 但是我这里就不用了, 一切为了速度~(不过mac主机可以用, 看不出影响)

备份

首先就是卸载omz(如果有)

 uninstall_oh_my_zsh
1

然后查看一下你的.zshrc和.zsh_history, 这两个文件需要备份一下,稍后会用到. 注意, 如果卸载omz, 那么omz会帮你备份, 文件名类似这样.zshrc.omz-uninstalled-2022-09-15_00-50-08. 然后.zshrc会被替换为在安装omz之前的配置, 可能会有不同, 大家注意区分.

cp .zshrc .zshrc_bak
1

创建配置文件夹

mkdir -p .zsh/plugins
cp .zshrc .zsh/
mv .zsh_history .zsh/

然后编辑.zshrc, 加上:

### ZSH HOME
export ZSH=$HOME/.zsh

### ---- history config ----------
export HISTFILE=$ZSH/.zsh_history

# How many commands zsh will load to memory.
export HISTSIZE=10000

# How maney commands history will save on file.
export SAVEHIST=10000

# History won't save duplicates.
setopt HIST_IGNORE_ALL_DUPS

# History won't show duplicates on search.
setopt HIST_FIND_NO_DUPS

安装插件

cd .zsh/plugins
git clone git@github.com:zdharma-zmirror/fast-syntax-highlighting.git

git clone git@github.com:zsh-users/zsh-autosuggestions.git

git clone git@github.com:zsh-users/zsh-completions.git

在.zshrc中添加:

source $ZSH/plugins/fast-syntax-highlighting/fast-syntax-highlighting.plugin.zsh
fpath=($ZSH/plugins/zsh-completions/src $fpath)

# zsh-autosuggestions:config
source $ZSH/plugins/zsh-autosuggestions/zsh-autosuggestions.zsh
ZSH_AUTOSUGGEST_HIGHLIGHT_STYLE="fg=#ff00ff,bg=cyan,bold,underline"
ZSH_AUTOSUGGEST_STRATEGY=(history completion)
ZSH_AUTOSUGGEST_BUFFER_MAX_SIZE=20

# end config

链接

最后就是创建符号链接, 这样我们就可以通过更改~/.zshrc来同步更改.zsh/.zshrc配置文件了.

首先需要确认家目录下没有.zshrc文件, 如果有, 将所有内容复制到.zsh/.zshrc中, 然后rm .zshrc.

此时可以开始创建符号链接了.

ln -s ~/.zsh/.zshrc ~/.zshrc

2

可以查看一下:

ls -la
.zshrc -> .zsh/.zshrc
1
2

然后:

source ~/.zshrc
1

即可完成~

PROMPT配置

由于我没安装主题插件, 这里就通过一行命令配置提示符进行配置, 参考了².

vim .zshrc
PROMPT=%(?.%F{green}√.%F{red}?%?)%f %B%F{140}%3~%f%b
source ~/.zshrc
1

最后的结果

√ ~/.zsh tree -L 2 -a
.
├── .zsh_history
├── .zshrc
└── plugins
    ├── fast-syntax-highlighting
    ├── zsh-autosuggestions
    └── zsh-completions
