Output Not Printed By Line

[dustinblackman]

I'm not 100% it was always like this but at the moment stdout doesn't print line by line, and instead spits everything out in one bulk. This python script is a google example.

I think it has something to do with how BufferedProcess is done, maybe use a modified version or switch to Spawn completely? Just pitching ideas.

import time
time.sleep(1)
print 'One'
time.sleep(1)
print 'Two'
time.sleep(10)
print 'Three'

EDIT: It seems to be something related to Python I guess, as my Coffeefiles are working correctly.

@dustinblackman This isn't Python specific. I've seen similar things with Ruby scripts run with Atom Script.

@dustinblackman As you mentioned switching to Spawn is one solution. It isn't a quick refactor Interaction with BufferedProcess is done on (besides setting the default to nil) these lines in ScriptView.

For Python, I believe I've found a workaround. You can reopen stdout and set it to line buffering, or no buffering.

import os,sys
sys.stdout = os.fdopen(sys.stdout.fileno(), 'w', 1) # line buffering

While I don't know of a way to solve this in Atom script I noticed this again the other day and wrote a sample Ruby script that allowed me to play around with this. If you enable all the IO#flush ($stdout/$stderr are both IO objects which can be flushed to force output to display).

puts "testing stdout\n" * 10
# $stdout.flush # Flush stdout/stderr to force output without a terminal based wait period (i.e. the order of STDOUT vs. STDERR is not guaranteed)
# sleep 2.0     # Add some sleep time to test output with intentional wait times

warn "testing stderr\n" * 10
# $stderr.flush # Flush stdout/stderr to force output without a terminal based wait period (i.e. the order of STDOUT vs. STDERR is not guaranteed)
# sleep 2.0     # Add some sleep time to test output with intentional wait times

puts "Lorem Ipsum, awesome stuff.\n" * 10
# $stdout.flush # Flush stdout/stderr to force output without a terminal based wait period (i.e. the order of STDOUT vs. STDERR is not guaranteed)
# sleep 2.0     # Add some sleep time to test output with intentional wait times

puts "done!"
