从源文件中查找函数调用的行号 [英] Find line number of function call from sourcing file

问题描述

我试图找到一种方法来找出函数是从哪个文件和行号调用的.该函数位于由我的脚本提供的库文件中.

I'm trying to find a way to find out what file and line number a function was called from. The function is in a library file which is being sourced by my script.

文件 1:

$source file2
$warn_me "Error: You didn't do something"

文件 2:

$function warn_me() {
$  message=????
$  echo ${message}
$}

期望的输出: $: file1:Line 2:错误:你没有做任何事情

函数调用已经在许多文件中多次出现，所以我试图找到一种方法来做到这一点而不改变它.

The function call already occurs many times in many files so I'm trying to find a way to do this without changing that.

以前在使用它的每个文件中都定义了warn_me 函数，并像这样处理:

Previously the warn_me function was defined in every file that used it and this was taken care of like so:

$local message="$BASH_SOURCE:(""${BASH_LINENO}): ""$*"

推荐答案

您正在寻找 caller 好像.

You are looking for caller it seems.

$ cat h.sh 
#! /bin/bash
function warn_me() {
  echo "$@"
  caller 
}
$ cat g.sh 
#!/bin/bash
source h.sh
warn_me "Error: You didn't do something"
$ . g.sh
Error: You didn't do something
3 g.sh
