I an using pipeShell, I have redirected stdout, stderr, and stdin.
I am trying to read from the output and display it in my app. I
have followed this code almost exactly except I use try wait and
flush because the app is continuously updating the output. (it
outputs a progress text on the same line and I'm trying to poll
it to report to the user)
auto pipes = pipeProcess("my_application", Redirect.stdout |
Redirect.stderr);
scope(exit) wait(pipes.pid);
// Store lines of output.
string[] output;
foreach (line; pipes.stdout.byLine) output ~= line.idup;
// Store lines of errors.
string[] errors;
foreach (line; pipes.stderr.byLine) errors ~= line.idup;
My code
auto p = pipeShell(`app.exe "`~f.name~`"`, Redirect.stdout |
Redirect.stdin | Redirect.stderr);
while(!tryWait(p.pid).terminated)
{
string[] output;
foreach (line; p.stdout.byLine)
{
output ~= line.idup;
writeln(line);
}
string[] errors;
foreach (line; p.stderr.byLine)
{
errors ~= line.idup;
writeln("Err:"~line);
}
}
wait(p.pid);
None of this works though. What is strange is that when I close
out the debugger the app starts working(no console output but I
able to see that it is doing something) but is very slow.
auto p = executeShell(`app.exe "`~f.name~`"`);
Does work, except I have no output or input. I have another app
that I do the exact same code and I can get the output and parse
it, but this is after the app terminates. I imagine the issue
here is that I'm trying to get the output while the app is
running.
I want to be able to get the output so I can reduce much of the
clutter and give a progress report. I am ok with simply hooking
up the in and out of the console of the app to mine just as if I
ran app.exe directly.
