ECMA-48 standard, 5th edition (especially sections 5.3 and 5.3).the ANSI escape codes overview on Wikipedia.Which can be condensed down to # 7-bit and 8-bit C1 ANSI sequencesĪnsi_escape_8bit = ansi_escape_8bit.sub(b'', somebytesvalue) Result = ansi_escape_8bit.sub(b'', somebytesvalue) (?: # either 7-bit C1, two bytes, ESC Fe (omitting # or a single 8-bit byte Fe (omitting CSI) If you do need to cover the 8-bit codes too (and are then, presumably, working with bytes values) then the regular expression becomes a bytes pattern like this: # 7-bit and 8-bit C1 ANSI sequences The latter are never used in today's UTF-8 world where the same range of bytes have a different meaning. The above regular expression covers all 7-bit ANSI C1 escape sequences, but not the 8-bit C1 escape sequence openers. Or, without the VERBOSE flag, in condensed form: ansi_escape = ansi_escape.sub('', sometext) (?: # 7-bit C1 Fe (except # or [ for CSI, followed by a control sequence If you want to use a special config file for just one DOS application, you can make a copy of the "MSDOS shortcut", or you can make a copy of "_default.pif", found in your Windows folder.Delete them with a regular expression: import re lnk file to CMD, you won't be able to set special config and autoexec files, it will use the default CONFIG.NT. On Win 2K and XP, the default "shortcut" for MSDOS is a. You will need to be an Administrator to edit that default file, or you can make a copy of it. In any case, when you use an actual DOS version of, ansi is enabled after being loaded: you can demonstrate it's use with a bit of ansi art like this: command /c type ansiart.ansĬONFIG.NT (in the system32 folder) contains an example of the syntax for loading device drivers. For some reason that I do not understand, on WinXP, even if you load a fixed copy of using " /p", the command prompt will not be ansi enabled: perhaps when you do it that way it only emulates loading ? On Win 2K and XP, loading ansi.sys will have no effect on your "CMD prompt" because CMD is not a DOS program: it is a 32 bit Windows console program. On earlier versions of NT, you can and must load a proper DOS environment to load ansi.sys, and ansi art will work at the prompt. When ansi.sys is loaded correctly, mem /d will report that it is loaded. On Windows NT 5 (2K & XP), each copy of the DOS subsystem can be given a separate config file in the pif/shortcut (use the "advanced" button), and there is a default file called CONFIG.NT (also in the system32 folder), which is used if the pif/shortcut does not specify a special config file. To load ansi.sys, you must use the device= or devicehigh= command in config, just as you would in MSDOS. Programs that run in the DOS subsystem and use standard output can use ANSI.SYS just as they could running over MSDOS. In 2000 and XP, it is located in the system32 folder (I don't remember the structure of earlier versions of NT). enable ansi colors in windows command promptĪnsi.sys (in the system32 folder) is an "MSDOS driver" provided as part of Windows XP, 2000, and earlier versions of NT.How can I get cmd.exe to display ANSI color escape sequences?.How to load ANSI escape codes or get coloured file listing in WinXP cmd shell?.It is written in C, supports 32-bit and 64-bit versions of Windows, and the source is available.Īlso I found some other similar question or post which ultimately have been answered to use ANSICON: So I think ANSICON by Jason Hood is your solution. Software such as Ansicon can however act as a wrapper around the standard Win32 console and add support for ANSI escape sequences. The Win32 console does not natively support ANSI escape sequences at all. Instead, Microsoft created a lot of functions, but this is far from your need to operate ANSI/VT100 escape sequence.įor a more detailed explanation, see the Wikipedia article:ĪNSI.SYS also works in NT-derived systems for 16-bit legacy programs executing under the NTVDM. According to the article: we all love colors, modern versions of Windows do not have this nice ANSI support. Microsoft KB101875 explains how to enable ANSI.SYS in a command window, but it does not apply to Windows NT. While for versions before Windows 10 Anniversary Update:ĪNSI.SYS has a restriction that it can run only in the context of the MS-DOS sub-system under Windows 95-Vista.
