vscode，如何启动和调试从管道读取的程序

Question

我需要调试我的程序callfilter，当它在Visual Studio代码中这样启动时：

zcat file.gz | build/callfilter/callfilter -M 10

这在vscode中可行吗？以下是它的当前启动配置，它可以在没有任何管道输入的情况下启动它：

"configurations": [
{
"name": "(gdb) callfilter",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}/build/callfilter/callfilter",
"args": ["-M", "10"],
"stopAtEntry": true,
"cwd": "${workspaceFolder}",
"environment": [],

"externalConsole": false,
"MIMode": "gdb",
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
}
]
},

Answer 1

它的工作原理是填充要从管道读取的args："args": ["<", "in.txt"]
