zsh - 如何将此 zsh 函数转换为 Fish shell？

Question

我有这个函数，在 zsh 中运行得很好，但我想将它转换为 Fish shell，但无法让它运行。

function ogf () {
  echo "Cloning, your editor will open when clone has completed..."
  source <(TARGET_DIRECTORY=~/students EDITOR=$EDITOR clone_git_file -ts "$1")
}

首先，由于fish的语法与zsh不同，您还必须将clone_git_file的输出更改为source它。

例如，如果 clone_git_file 类似于:

#!/bin/bash
echo "FOO=$TARGET_DIRECTORY"
echo "BAR=$2"

你必须将其更改为fish语法。

#!/bin/bash
echo "set -gx FOO $TARGET_DIRECTORY"
echo "set -gx BAR $2"

现在这是 ogf() 函数，以及 Fish 的示例代码:

function ogf
  echo "Cloning, your editor will open when clone has completed..."
  source (env TARGET_DIRECTORY=~/students EDITOR=$EDITOR clone_git_file -ts $argv[1] | psub)
end

ogf MY_ARGUMENT
echo "FOO is $FOO"
echo "BAR is $BAR"

用fish运行这段代码，输出是:

FOO is /home/MY_USER/students
BAR is MY_ARGUMENT
