修复 powerline-shell bash 提示（模式：“兼容”或模式：“修补”）

背景

我有问题powerline-shell提示；由于某种原因，我找不到任何方法来构建图形>电力线角色。

我使用以下命令安装了 python powerline json 配置：

$ mkdir -p ~/.config/powerline-shell && \
powerline-shell --generate-config > ~/.config/powerline-shell/config.json

顺便说一下，我使用 putty 通过 ssh 进入我的系统。无论我设置$TERM为xterm-256color还是 ，putty电力线提示渲染都没有区别。

我的~/.config/powerline-shell/config.json内容...

显然，此配置用于mode: flat解决>渲染问题。

$  cat ~/.config/powerline-shell/config.json

{
  "mode": "flat",
  "segments": [
    "virtual_env",
    "aws_profile",
    "ssh",
    "cwd",
    "git",
    "git_stash",
    "jobs",
    "set_term_title",
    "svn",
    "newline",
    "root"
  ],
  "cwd": {
    "mode": "flat"
  },
  "theme": "default"
}

渲染powerline-shell模式：平面

当我使用时"mode": "flat",，~/.config/powerline-shell/config.json提示看起来很好...应该注意flat提示模式不使用图形>字符......

powerline_with_mode_flat

渲染powerline-shell模式：兼容

当我在 中使用"mode": "patched"或时，"mode": "compatible"~/.config/powerline-shell/config.json图形>字符是必需的，但似乎不存在（请参阅底部的注释）。

powerline_with_mode_patched

问题

我该如何修复此powerline-shell提示安装以使用mode: compatible或patched？

我安装了一个中心powerline-shell脚本，每次使用时/opt/bin/powerline-shell都会以完整路径调用该脚本。/opt

我的.bashrc内容...

$ cat ~/.bashrc

# .bashrc - Always executed for a new shell, unlike .bash_profile,
#           which normally isn't run for terms without the -ls option

export PYTHON_CONFIGURE_OPTS="--enable-shared"

# I built a custom vim-9.0 in /opt/vim90
export VIMRUNTIME="/opt/vim90/runtime/"

# Run a whois query that retrieves info from Team CYMRU about an IP
function cwhois_fn {
    whois -h whois.cymru.com " -v $1"
}

# Use vi for term line edits
set -o vi

我在 Debian 11 系统上使用mode: patched（参考下文）实现了这个功能......~/.config/powerline-shell/config.json

  • 具体命令...
    • sudo apt-get install fonts-powerline fonts-hack powerline
    • pip install powerline-shell
    • git clone https://github.com/ryanoasis/nerd-fonts; cd nerd-fonts; rm -rf .git; install.sh; # install.sh installs the nerd-fonts
    • 我的~/.bashrc添加/更改：
function _update_ps1() {
    # /opt/bin/powerline-shell should be manually-installed
    #     see the script at the bottom of this superuser answer
    PS1=$(/opt/bin/powerline-shell $?)
}

export TERM="xterm-256color"

if [[ $TERM != linux && ! $PROMPT_COMMAND =~ _update_ps1 ]]
then
    PROMPT_COMMAND="_update_ps1; $PROMPT_COMMAND"
    export PROMPT_COMMAND
else
    export PS1='[\u@\h \W]\$ '
    export PROMPT_COMMAND="$PS1"
fi
