Vs code passes parameters containing semicolons to the program

[cooper-zhzhang]

int main(int argc, char *argv[]) {

    for (int i = 0; i < argc; i++)
    {   
        printf("%s\n", argv[i]);
    }   

    return 0;
}

set args:["1;3"]
i hope display
a.out
1;3
but result is
a.out
1
my system is ubuntu 16.04

It is very unlikely that VSCode has anything to do with that.

Ho do you run the program?

I need to input arguments that is a string with semicolons, like"address;topic".

When the arguments comes from ubuntu terminal command, the argument is "address;topic" exactly what I want.
But when they are comes from launch.json which is needed in vscode, all the characters behind the semicolon is ignored. It becomes to "address" without ";topic".

How to set the "args" parameter in launch.json to get strings input with semicolons?

Having one "args": [ "address;topic"] is IMO the right thing to do.

Can you paste the full configuration that you have in launch.json? I'd like to see the type of the configuration.

Hi!@aeschli
Thanks for your reply.

Bellow is my semicolons_test.c

#include <stdio.h>

int main(int argc, char *argv[])
{
    for (int i=0;i<argc;i++)
    {
        printf("%s\n",argv[i]);
    }
    return 0;
}

And launch.json

"version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/semicolons-test",
            "args": ["address;topic"],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "M"
        }
    ]

output in Vscode

/home/dreamdeck/Desktop/test/semicolons-test
address

input and output in Linux terminal

$ gcc -o semicolons-test semicolons_test.c
$ ./semicolons-test "address;topic"
./semicolons-test
address;topic

Thanks @MolianWH !

Assigning to @weinand to decide whether this is a cpp issue or not.

We are now properly escaping ';' for unix shells.
