如何将此 zsh 函数转换为鱼壳?

问题描述

我有这个在 zsh 中运行良好的函数，但我想将其转换为鱼壳，但无法正常工作.

I have this function which works great in zsh, but I want to convert it to fish shell and I can't get it working.

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

推荐答案

首先，由于fish的语法和zsh不同，所以你还要把clone_git_file的输出改成source 它.

First of all, since fish's syntax differs from zsh, you also have to change the output of clone_git_file to source it.

例如，如果 clone_git_file 类似于:

For example, if clone_git_file is something like:

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

你必须把它改成鱼语法.

you have to change it to fish syntax.

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

现在是 ogf() 函数和鱼的示例代码:

Now here's the ogf() function, and sample code for fish:

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，输出为:

Running this code with fish, the output is:

FOO is /home/MY_USER/students
BAR is MY_ARGUMENT
