Redirect standard input/output to files #122

Closed jeissonh closed 7 years ago

jeissonh commented 7 years ago

On Unix systems, GDB accepts to use a pseudoterminal to send input to the inferior, and capture its standard output and error, with set-tty commands (GDB manual 4.6). On Windows, the inferior's IO is done directly in the same tty that GDB uses. In any case, the standard input/output of the inferior can be redirect in the run command:

run < /tmp/sum_xy.input > /tmp/sum_xy.output

In all OS redirecting input to a file may be very convenient. [In the future this redirection may be disabled only when user runs his/her own code not linked to a botnu file].

Redirecting the standard output may be useful in Windows, but probably GDB manages it well. Standard input is the difficult one, at least in Gede and QtCreator.

On Unix systems standard input/output/error are redirected to the files of the test case. Implemented in commit 52f224f8786d526a1f998a118884e3291effb013
