![]() ![]() Kernel32.SetConsoleMode(kernel32.GetStdHandle(-11), 7)Īgreed this would be worthwhile setting on stdout by default. The following proof of concept script correctly displays coloured text: This works fine for me in Windows terminal, but I see the behaviour described when using the conventional "Command prompt" window.Įnabling ANSI codes is handled via SetConsoleMode (see here: ). Then display that file at the command prompt. For an example of how these sequences are used in practice, please see the example at the end of this topic. To emphasize that ANSI codes ARE a feature of the command prompt, comment out that line to disable the ANSI codes in print(), but redirect the output to a text file. Either way, the inconsistency of the handling should be fixed. I'm using (just for today) Windows 10 Enterprise, version 1709, build 16299. The trick is that a certain registry key must be set. ANSI code handling was present from the start of Windows 10, so it's reasonable to presume that it's now a permanent feature of the Windows command prompt window. Sending the ANSI escape sequences should work, according to thousands of fine answers on the internet, but one obscure detail took me two half days to stumble upon. To be consistent with Python on Linux and Mac, I believe that ANSI codes should be permanently enabled in Windows 10 rather than removed. Print(ansi_red + "This is red!" + ansi_normal) This means that the logging level cant be part of the message either, it has to be a separate parameter. Any Unicode character can be encoded this way, but. If you want to emulate what a logging library does, you should check the logging level inside Logger and emit escape sequences only for Warning messages, only to the terminal. Os.system("") # Comment this out to disable ANSI codes Individual code units which form parts of a surrogate pair can be encoded using this escape sequence. ![]() Comment-out the apparently meaningless os.system("") line and ANSI codes do not work, but leave that line in and ANSI codes DO work: The correct handling of ANSI escape codes by the print() function may or may not be enabled in the Windows 10 command prompt window, depending on previous system calls. Lets assume that you have the string data for each column (before adding escape sequences) in a list named stringdata and the pre-determined column widths are in a list named width. If they do, the currently accepted answer wont work anyway. Inconsistent ANSI escape code handling on Windows 10ĭaverove, paul.moore, steve.dower, tim.golden, zach.wareĬreated on 11:05 by daverove, last changed 14:59 by admin. Lets presume that none of the escape sequences change the cursor position. ![]()
