Display attribute *[m settings Sending site: Sun and Moon Guanghua December 14, 2003 00:37:40 Sunday, site mail Display properties are one of the most commonly used ANSI controls. Settable items include Foreground color text color background color Highlight status settings text underline flash text Reverse display There are 16 colors that we can set on BBS, including 8 low-brightness colors and 8 high-brightness colors. In order to avoid the impact caused by other aspects, please turn off the default highlighting and other settings of the terminal software first. cterm2000: Edit>>System Settings>>Advanced Confirm that it is always highlighted if it is not selected fterm: Options>>Parameter Settings Make sure default highlighting is not selected sterm: Options>>Current connection settings>>Remote login settings>>Appearance Confirm that it is always highlighted if it is not selected Okay, let’s start now. Take a look at the picture below. Set display properties *[p1;p2;...;pnm p1...pn are some integers, the meaning is as follows, m must be lowercase, ;32m* is typed by ESC twice, not * on the keyboard 0 Turn off each display attribute 30 31 32 33 34 35 36 37 1 Highlight Color Code Mnemonics 40 ss ss ss ss ss ss ss ss 4 underscore 41 ss ss ss ss ss ss ss ss 5 flashing 1 red 2 green 4 blue 42 ss ss ss ss ss ss ss ss 7 reverse display 3 red green yellow 43 ss ss ss ss ss ss ss ss 5 red blue purple 44 ss ss ss ss ss ss ss ss 30 37Set the foreground color 6 green blue cyan 45 ss ss ss ss ss ss ss ss 40 47Set background color 7 red green blue white 46 ss ss ss ss ss ss ssss. 0 is black 47 ss ss ss ss ss ss ss ss *[m is similar to *[0m. They can turn off flickering, underlining and inverting, and restore the default background color. Parameters can be set continuously: For example, *[0;1;5;32;46m is equivalent to *[0m*[1m*[5m*[32m*[46m 30 37 is used to set the foreground color. You can remember the color according to the picture above, or you can directly memorize 8 corresponding colors. *[30m black *[31m red *[32m green *[33m yellow *[34m blue *[35m purple *[36m cyan *[37m dark white To get the corresponding highlight color use *[1m *[1m*[31m is the same as *[1;31m. Generally, the latter is used to make the code shorter. Use 40 47 to set the background color. The background colors are all low-bright, so there are only 8 types. *[5m flashing. It should be noted that generally speaking, the flashing parts on a screen should not be too concentrated or too concentrated. *[4m is underline In cterm, the underline is always white. The color of the underline in fterm or sterm is the same as the color of the text in the corresponding position. *[7m reverse display is recommended not to be used. Various terminal software’s interpretations vary greatly. In cterm, the background is exchanged. Highlighting only affects the foreground. Ignore the background color in fterm and use black text on a white background Swap the front and background in sterm and apply the highlight to the background color Therefore, there may be a situation where the background is highlighted and the foreground is low in sterm. *[0m is similar to *[m. Turn off the flashing underline display and restore the default background color. It's the same at Shuimu or Zixia stations. sterm has the same explanation for both People who use cterm or fterm on other BBS *[0m will return to low brightness *[mRestore to the default high and low brightness state according to your settings If you are on a site such as Shuimu or Zixia, or if you are using sterm When it is set to the default highlight, you will not get the low-light color. If your default background in fterm or cterm is set to another color than black *[40m will switch to default background color instead of black sterm may switch to black Generally speaking, the length of a line of code in BBS can be up to 254 characters, and one Chinese character counts as two characters. There may be stricter restrictions on activity boards, etc., and the allowed code length is shorter. Therefore, sometimes you must use the shortest possible code. Do not set repeated codes multiple times. For example, *[0;32;41mGreen characters on red background*[1;32;43mHighlighting green characters on yellow background*[5;1;31;43mHighlighting flashing red characters on yellow background This line of code can be shortened to *[0;32;41mGreen characters on red background*[1;43mHighlighting green characters on yellow background*[5;31mHighlighting flashing red characters on yellow background Streamlining code is also a science. I won’t talk about it here. 254 characters is actually not too much. Generally, there are 80 visible characters in one line. If you switch the color once each time, setting the foreground color requires adding 5 characters. 6*80 480 is far beyond 254 Therefore, the color changes within a row are still subject to certain restrictions. Unless you reach the bottom of the screen, the display attributes at the end of the previous line will continue to the next line. This should also be noted.
