I am using popen to redirect the output of prosv5 terminal to a program that processes said output, which is a very long log that can only be transferred over the terminal. However, the following error keeps occurring:
RoboGod

OSError: [Errno 22] Invalid argument
2 event(s) loaded from robot recorder.
The above errors stem from the stderr output of pros terminal. In addition, I do not have a micro sd card, and I’d rather not get one unless transferring the data over the terminal does not work out at all.
In essence, here is the “psuedocode”(it’s for a specially designed compiler) that captures the interactions. I’ll attach the transpiled c output, which is a PC program.
def loadEvents() array<event>:
cdef popen(handle, handle) handle
cdef pclose(handle) None
cdef strerror(int) handle
cdef puts(handle) None
cdef sleep_ms(int) None
cdef errno int
terminal = popen(cmd="prosv5 terminal\0", mode="r\0")
#terminal = popen(cmd="type testdata.txt\0", mode="r\0")
if terminal == 0:
puts(strerror(errno))
abort "Cannot open pros terminal."
reader = new io::reader(terminal)
writer = io::output() #thats just how popen is - stdout is redirected as input into pros terminal
if reader.consumeTillPhrase("ROBOGODAWK") == False:
abort "Robogod never encountered ROBOGODAWK keyword!"
reader.consumeWhitespace()
events = new data::list<event>(reader.readInt(), new motorBrake(0, 0)) #motorBrake is a dummy event
reader.consumeWhitespace()
writer.write("Loading ")
writer.write(events.buffer as int)
writer.writeLine(" event(s)....")
def loadEvent() nullable<event>:
reader.consumeWhitespace()
reader.readWhile(lambda char c: c != 'S' and c != 'M' and c != 'B' and c != 'R')
if (eventType = reader.readChar()) == 'S': #stop loading events
return None
reader.consumeWhitespace()
timeStamp = reader.readInt()
reader.consumeWhitespace()
magnitude = reader.readDec()
reader.consumeWhitespace()
velocity = reader.readInt()
reader.consumeWhitespace()
port = reader.readInt()
reader.consumeWhitespace()
if eventType == 'M': #motor move
return new motorMove(port, magnitude, timeStamp)
elif eventType == 'R': #motor move
return new motorMoveRelative(port, magnitude, velocity, timeStamp)
elif eventType == 'B': #motor brake
return new motorBrake(port, timeStamp)
else:
cdef printf(handle, char, int, int) None
printf(fmt = "Character is '%c', ASCII code is %i. Loaded %i events so far.\n", eventType, eventType, events.count)
abort "Invalid event code recieved during transmission."
while True:
writer.write(events.count)
writer.write('/')
writer.write(events.buffer as int)
match res=loadEvent():
None:
pclose(terminal)
writer.writeLine('\r')
return events.toArray()
event e:
events.pushBack(e)
sleep_ms(450)
writer.write('\r')
I’m pretty sure the code itself is working fine. It works when I run it against a similar program that simulates pros terminal.
