问题

I trying to debug (for study purposes) simple program written with c language. I use vimspector(gdb) as debugger.
我正在尝试调试（用于学习目的）用C语言编写的简单程序。我使用vimspector(gdb)作为调试器。

How can I read memory at certain address with vimspector?
如何使用vimspector读取特定地址的内存？

I found vimspector can do this (someone's screenshot as a proof):
我发现vimspector可以做到这一点（有人的截图作为证据）：

Section "dump memory" of vimspector's readme says:
vimspector的自述文件中的“dump memory”部分说：

Some debug adapters provide a way to dump process memory associated with variables. This can be done from the Variables and Watches windows with:
一些调试适配器提供了一种用于转储与变量关联的进程内存的方法。可以从变量和观察窗口执行此操作：

• The WinBar option "Dump"
• WinBar选项“Dump”
• m mapping (by default, can be customised)
• m映射（默认情况下可以自定义）
• vimspector#ReadMemory() function
  vimspector#ReadMemory()函数

I tried to call function vimspector#ReadMemory and got errors everytime
我尝试调用vimspector#ReadMemory函数，并每次都遇到错误：

:call vimspector#ReadMemory()
Cannot find memory reference for that
无法找到该内存引用

:call vimspector#ReadMemory(myvar)
E116: Invalid arguments for function vimspector#ReadMemory
E116: vimspector#ReadMemory函数的参数无效

:call vimspector#ReadMemory(0x7ffff7e959d7)
TypeError: vimspector.debug_session.DebugSession.ReadMemory() argument after ** must be a mapping, not str
TypeError: vimspector.debug_session.DebugSession.ReadMemory()的参数**后必须是映射，而不是字符串

When I trying <leader>m nothing happened.
当我尝试<leader>m时，什么都没有发生。

:call vimspector#ReadMemory()
Cannot find memory reference for that

:call vimspector#ReadMemory(myvar)
E116: Invalid arguments for function vimspector#ReadMemory

:call vimspector#ReadMemory(0x7ffff7e959d7)
TypeError: vimspector.debug_session.DebugSession.ReadMemory() argument after ** must be a mapping, not str

I also find this issue and search by google, found your question, but seems no one answers it, by serval minutes of trying, I found the root cause, you need to trigger this function inside variable or watch windows, by default, they were layout at left side. then you can press m on a variable or address, magic will happen.

please mentions that, after trigger m, you need to wait about 2 seconds, then vimspector will ask you to input some parameters to dump the memory.

hopes this will help you
