It can usually be used to set the foreground color, that is, the text color. Color, background color, highlight state, text underline, flashing text and reverse display, etc. Let’s first introduce the commonly used colors in BBS. A total of 16 different colors can be set, including 8 colors. Low light color and 8 highlight colors are shown below. This is the same as ANSIEditor's color toolbar: low light color Highlight color In order to avoid other impacts, please turn off the default highlighting setting of the term software first. Cterm: Tools>System Parameter Settings>Display Select normal display, mainly low-brightness colors Sterm: Options>Default Settings>Appearance Uncheck to always highlight Fterm: Options>Parameter settings If not selected, it will be highlighted by default. The code to set the display attribute is *[p1;p2;...;pnm Among them * is the ASCII control character. Press the ESC key twice in a row in the telnet editing state to get Note that it is not The asterisk p1...pn obtained by pressing shift 8 is an integer, and its meaning is as follows. m must be lowercase 0 Turn off various display attributes: *[m is similar to *[0m. They can turn off attributes such as blinking, underlining and inverse display. Display and restore to default background color 1 Highlight: *[1m can get the corresponding highlight color *[1m*[31m and *[1;31m have the same effect Generally the latter is used to make the code shorter 4 Underline: *[4m can add underline to the text. In Cterm, the underline is always white. The color of the underline in Sterm or Fterm is the same as the color of the text in the corresponding position. 5 Flashing: *[5m can set the flashing effect for the text. Generally speaking, the flashing text on the screen should not be too large. Concentrating too much can distract you. 7 Reverse display: *[7m sets the reverse display effect. It is recommended not to use it because various term software interprets it differently. Larger. In Cterm, the front and background are exchanged. Highlighting only applies to the foreground. In Sterm, the front and background are exchanged. And The highlight will be applied to the background color, so there may be a situation where the background is highlighted and the foreground is low in Fterm. Ignore the foreground and background color and use black text on a white background 30 37 Set foreground color: 40 47 Set background color: *[30m black *[34m blue *[40m dark black *[44m dark blue *[31m red *[35m purple *[41m dark red *[45m dark purple *[32m green *[36m cyan *[42m dark green *[46m dark cyan *[33m yellow *[37m white *[43m dark yellow *[47m dark white Simplified code Generally speaking, the length of a line of code in BBS should not exceed 254 English characters. For event billboards, etc., it is more strict. The limitation of the format allows shorter code length, so sometimes it is necessary to use the shortest possible code. Repeated code Do not set the code multiple times. For example: Highlight foundation with white characters Highlighting blue with yellow characters Flashing red with yellow characters Normally the code can be written as: *[1;37;45mHighlight foundation with white text*[1;33;44mHighlight blue with yellow text*[0;5;33;41mFlashing red with yellow text The above code can be simplified to *[1;37;45mHighlight foundation with white text*[33;44mHighlight blue with yellow text*[0;5;41mFlashing red with yellow text The highlight state remains unchanged and the foreground color remains unchanged. It should be noted that if the above code does not use *[m or *[0m to turn off each display attribute, then the previous line The display properties at the end will continue to the next line unless the bottom of the screen is reached. Introduction to other control characters The following ANSI control characters are used to create qmd with more than 6 lines, color ID, color nickname, and vertical ones on the right. It will be used when making qmd. List it first. Students who are capable can choose to learn it. It will also be mentioned later when making qmd: *[nA Move the cursor up n lines *[2J Clear the screen and move the cursor to the upper left corner of the screen *[nB Move the cursor down n lines *[K Clear the content from the cursor to the end of the line *[nC Move the cursor n columns to the right *[s Save the cursor position *[nD Move the cursor n columns to the left *[u Restore the cursor position *[y;xH Move the cursor to column x and row y Special commands for editing articles under telnet Select a course ESC C View color editing results ESC M Block operation ESC G Jump to the specified line ESC F Set foreground color ESC D Delete block Ctrl S Jump to the first line ESC B Set background color ESC Q Clear calibration Ctrl T Jump to the last line ESC R Restore color Ctrl U Calibrate block ESC L Open or close the message bar Ctrl C Copy block ESC I Import file Ctrl K Delete to end of line ESC E Export file Ctrl Y Delete entire line Insert toggle insert replacement mode Among them, the commands indicated in yellow are more commonly used. It is recommended to master them. Operation 1. Memorize the meaning of the following control codes: *[0m *[1m *[4m *[5m *[7m *[30m *[37m *[40m *[47m 2. Write the meaning of each control code mentioned above and attach the effect. The specific content is arranged by the students themselves. However, To include all the above control codes, please write them directly in the term software under telnet and not under the web. Do not use ANSIEditor to edit. Please pay attention to the simplification of the code when writing. After writing, send it to each of you via letter. designated teacher Attached is my homework from the first training class for your reference: *[1;34;47m Highlight white background and dark blue characters. Let me show you a limerick I wrote in high school. *[4;5;30;41m Underline flashing red background black text Untitled poem when you wake up from doze *[0;33;45m foundation with yellow characters by comeonfulin *[1;32;41m Highlight green text on red background Spring is not a day for reading *[1;31;46m High-brightness red text on a sky blue background, perfect for sleeping in the hot summer *[1;33;44m Highlight dark blue background with yellow characters. There are mosquitoes in autumn and are afraid of cold in winter. *[1;37;45m Highlight foundation with white letters. Pack your schoolbag for next year. Finally, make an ANSIEditor with reverse display. Didn’t you say that you shouldn’t use reverse display easily? *[1;4;7m If the highlight is inverted, then use ANSIEditor to invert the highlight, haha Preview of the fifth lecture: Copy and paste between ANSIEditor and various terms
