### Overview

`coop` allows you to pair-debug programs without having to share a screen and a keyboard.

Simply run `coop  ...` to start a server running ` `

interactively, and attach additional clients with `coop`. Clients can come and go at any time.

Optionally specify an endpoint and port with `--endpoint` and `--port`. See `coop --help` for

more info.

### Building

    stack build

### Installing (local user)

    stack install

### Sample session

(You'll have to use your imagination to untangle the order these commands were input)

##### Server/Client 1

    $ coop --endpoint 10.0.0.14 --port 5678 gdb a.out

    Spawning 'gdb a.out'

    Subscribing to input on 'tcp://10.0.0.14:5678'

    Publishing input and output on 'tcp://10.0.0.14:5679'

    Press enter when client(s) are ready.

    ...

    Reading symbols from a.out...done.

    (gdb) [fjdt]: b main

    Breakpoint 1 at 0x40050e: file foo.c, line 4.

    (gdb) [fjdt]: r

    Starting program: /home/mitchell/a.out

    Breakpoint 1, main () at foo.c:4

    4	    printf("Hello, world!\n");

    (gdb) n

    5	    int a = 5;

    (gdb) n

    6	    a += 1;

    (gdb) n

    7	    a += 2;

    (gdb) n

    8	    a += 4;

    (gdb) [fjdt]: n

    9	    printf("a = %d\n", a);

    (gdb) [fjdt]: n

    10	    return 0;

    (gdb) [fjdt]: n

    11	}

##### Client 2

    $ coop --endpoint 10.0.0.14 --port 5678

    Publishing input on 'tcp://10.0.0.14:5678'

    Subscribing to output on 'tcp://10.0.0.14:5679'

    ...

    Reading symbols from a.out...done.

    (gdb) b main

    Breakpoint 1 at 0x40050e: file foo.c, line 4.

    (gdb) r

    Starting program: /home/mitchell/a.out 

    Breakpoint 1, main () at foo.c:4

    4	    printf("Hello, world!\n");

    (gdb) [gxoc]: n

    5	    int a = 5;

    (gdb) [gxoc]: n

    6	    a += 1;

    (gdb) [gxoc]: n

    7	    a += 2;

    (gdb) [gxoc]: n

    8	    a += 4;

    (gdb) n

    9	    printf("a = %d\n", a);

    (gdb) n

    10	    return 0;

    (gdb) n

    11	}

###### foo.c

```c

#include 

int main() {

    printf("Hello, world!\n");

    int a = 5;

    a += 1;

    a += 2;

    a += 4;

    printf("a = %d\n", a);

    return 0;

}
