Location Specifiers - 位置说明符
Several delve commands take a program location as an argument, the syntax accepted by this commands is:
多个 delve 命令接受程序位置作为参数，以下是这些命令接受的语法：
*<address>Specifies the location of memory address address. address can be specified as a decimal, hexadecimal or octal number*<address>指定内存地址 address 的位置。address 可以是十进制、十六进制或八进制数字。
<filename>:<line>Specifies the line line in filename. filename can be the partial path to a file or even just the base name as long as the expression remains unambiguous.<filename>:<line>指定 filename 中的 line 行。filename 可以是文件的部分路径，甚至仅仅是文件的基本名称，只要表达式没有歧义。
<line>Specifies the line line in the current file<line>指定当前文件中的 line 行。
+<offset>Specifies the line offset lines after the current one+<offset>指定当前行后 offset 行。
-<offset>Specifies the line offset lines before the current one-<offset>指定当前行前 offset 行。
<function>[:<line>]Specifies the line line inside function. The full syntax for function is<package>.(*<receiver type>).<function name>however the only required element is the function name, everything else can be omitted as long as the expression remains unambiguous. For setting a breakpoint on an init function (ex: main.init), the<filename>:<line>syntax should be used to break in the correct init function at the correct location.<function>[:<line>]指定 function 内的 line 行。function 的完整语法是<package>.(*<receiver type>).<function name>，但仅需提供函数名，其他部分可以省略，只要表达式没有歧义。要在 init 函数（例如：main.init）上设置断点，应使用<filename>:<line>语法来在正确的位置断开正确的 init 函数。
/<regex>/Specifies the location of all the functions matching regex/<regex>/指定所有匹配 regex 的函数的位置。
