给 Nu shell 配置上 Oh My Posh，完成后效果如下。

nu-ohmyposh

之前我已经给 powershell 配置好 ohmyposh 了，现在感觉还是 nu shell 比较好用，所以也来折腾一下。

官方文档：Change your prompt | Oh My Posh

有这些 shell 可以选择：

bash
cmd
elvish
fish
nu
powershell
tcsh
xonsh
zsh

点击中间的 nu 可以看到说明。

简单来说，就是修改 nushell 的两个配置文件就好。它们在 ~\AppData\Roaming\nushell 里面。

添加

oh-my-posh init nu

到 env.nu 里面，我直接写在第四行的位置。

# Nushell Environment Config File
alias ll = ls -l

oh-my-posh init nu

然后再到 config.nu 的最后，添加这一行。

source ~/.oh-my-posh.nu

它会生成 ~/.oh-my-posh.nu ，也就是在用户目录下。打开后里面是这些内容。

export-env {
    let-env POWERLINE_COMMAND = 'oh-my-posh'
    let-env POSH_THEME = ''
    let-env PROMPT_INDICATOR = ""
    let-env POSH_PID = (random uuid)
    # By default displays the right prompt on the first line
    # making it annoying when you have a multiline prompt
    # making the behavior different compared to other shells
    let-env PROMPT_COMMAND_RIGHT = {''}
    let-env POSH_SHELL_VERSION = (version | get version)

    # PROMPTS
    let-env PROMPT_MULTILINE_INDICATOR = (^"C:/Users/nucx/AppData/Local/Programs/oh-my-posh/bin/oh-my-posh.exe" print secondary $"--config=($env.POSH_THEME)" --shell=nu $"--shell-version=($env.POSH_SHELL_VERSION)")

    let-env PROMPT_COMMAND = {
        # We have to do this because the initial value of `$env.CMD_DURATION_MS` is always `0823`,
        # which is an official setting.
        # See https://github.com/nushell/nushell/discussions/6402#discussioncomment-3466687.
        let cmd_duration = if $env.CMD_DURATION_MS == "0823" { 0 } else { $env.CMD_DURATION_MS }

        # hack to set the cursor line to 1 when the user clears the screen
        # this obviously isn't bulletproof, but it's a start
        let clear = (history | last 1 | get 0.command) == "clear"

        let width = ((term size).columns | into string)
        ^"C:/Users/nucx/AppData/Local/Programs/oh-my-posh/bin/oh-my-posh.exe" print primary $"--config=($env.POSH_THEME)" --shell=nu $"--shell-version=($env.POSH_SHELL_VERSION)" $"--execution-time=($cmd_duration)" $"--error=($env.LAST_EXIT_CODE)" $"--terminal-width=($width)" $"--cleared=($clear)"
    }
}

if "false" == "true" {
    echo ""
}
