I think you’re looking for console.dir(). console.log() doesn’t do what you want because it prints a reference to the object, and by the time you pop it open, it’s changed. console.dir prints a directory of the properties in the object at the time you call it. The JSON idea below is a good one; you … Read more
You need to use print instead of puts. Also, if you want the dots to appear smoothly, you need to flush the stdout buffer after each print… def print_and_flush(str) print str $stdout.flush end 100.times do print_and_flush “.” sleep 1 end Edit: I was just looking into the reasoning behind flush to answer @rubyprince’s comment, and … Read more
This can be detected using isatty: if sys.stdout.isatty(): # You’re running in a real terminal else: # You’re being piped or redirected To demonstrate this in a shell: python -c “import sys; print(sys.stdout.isatty())” should write True python -c “import sys; print(sys.stdout.isatty())” | cat should write False
Yes, located near your console tab should be a button “Open Console”. If you click this button one of your options should be “New Console View”. You’ll now have 2 console views. One of your other buttons near your console tab is “Display Selected Console”. When you choose this option you can select from any … Read more
Since there are several answers here showing non-working code for Windows, here is a clarification: Runtime.getRuntime().exec(“cls”); This command does not work, for two reasons: There is no executable named cls.exe or cls.com in a standard Windows installation that could be invoked via Runtime.exec, as the well-known command cls is builtin to Windows’ command line interpreter. … Read more
The error is because of the sql mode which can be strict mode as per latest MYSQL 5.7 documentation MySQL Documentation 5.7 says: Strict mode affects whether the server permits ‘0000-00-00’ as a valid date: If strict mode is not enabled, ‘0000-00-00’ is permitted and inserts produce no warning. If strict mode is enabled, ‘0000-00-00’ … Read more
Here is a simpler method (hack) that gives you back the setdefaultencoding() function that was deleted from sys: import sys # sys.setdefaultencoding() does not exist, here! reload(sys) # Reload does the trick! sys.setdefaultencoding(‘UTF8’) (Note for Python 3.4+: reload() is in the importlib library.) This is not a safe thing to do, though: this is obviously … Read more
you can’t do a “while(done)” loop because that would require blocking on input, something node.js doesn’t like to do. Instead set up a callback to be called each time something is entered: var stdin = process.openStdin(); stdin.addListener(“data”, function(d) { // note: d is an object, and when converted to a string it will // end … Read more
If it is a simple single-source program, make foo where the source file is foo.c, foo.cpp, etc., you don’t even need a makefile. Make has enough built-in rules to build your source file into an executable of the same name, minus the extension. Running the executable just built is the same as running any program … Read more
Restarting Spring should fix the hanging commands: $ bin/spring stop I experienced hanging commands (rake, bin/rails, etc.) after deleting and recreating a new Ruby on Rails application. Google wasn’t that helpful. I hope this is. Spring will start automatically when you re-run your command.
