Memorizing some scii control codes is very useful. Let’s talk about color first There are 16 colors that we can set, including 8 low-brightness colors and 8 high-brightness colors. low light color Highlight color In order to avoid the impact caused by other aspects, please turn off the default highlighting and other settings of the terminal software first. Term Tools>>Options>>Display>>Normal text Make sure Force Highlighting is not selected Term Options>>Parameter Settings Make sure default highlighting is not selected Term options>>Current connection settings>>Remote login settings>>Appearance Confirm that it is always highlighted if it is not selected Set display properties *[p1;p2;...;pnm * is the Ascii control character, which can be obtained by pressing sc twice in editing mode. p1...pn are some integers. The meaning is as follows. m must be lowercase. 0 Close each display attribute 30 37 Set the foreground color 1 Highlight 40 47 Set background color 4 underline 5 Flashing *[m is similar to *[0m. Both of them can turn off flashing, underline and reverse display. 7 Invert the display and return to the default background color *[1m is to set the highlight color *[1m*[31m is the same as *[1;31m. Generally, the latter makes the code shorter. *[4m is to add 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. *[5m is flashing Be careful not to have too many or too concentrated flickers on one screen. *[7m is reverse display It is recommended not to use it. Various terms have very different interpretations of reverse display, which will produce different effects in the work. Simplified code 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 are stricter restrictions on activity boards, etc. The allowed code length is shorter, so sometimes it must Use as short a code as possible. Do not set repeated code multiple times. For example Highlight yellow characters on a white background Highlight yellow characters on a red background Flashing white characters on a green background *[0;33;47mYellow characters on white background*[1;33;41mHighlight yellow characters on red background*[1;5;37;42mHighlight flashing white characters on green background The above code can be shortened to *[0;33;47mYellow characters on white background*[1;41mHighlight yellow characters on red background*[5;37;42mHighlight flashing white characters on green background The foreground color remains unchanged and the highlight state remains unchanged. Note that the display properties at the end of the previous line will continue to the next line unless the bottom of the screen is reached. Cursor control *[nA Move the cursor up n lines *[nB Move cursor down n lines *[nC Move the cursor n columns to the right. The white characters on this page are *[nD Move the cursor n columns to the left and the written content is the selected reading content *[y;xH Move the cursor to column x and row y *[2J Clear screen *[K clears the contents from the cursor to the end of the line *[s save cursor position *[u restore cursor position Special command Please press ESC first, then select the following items I Import file E Export file C View color editing results B Set background color F Set foreground color R Restore color ESC color control code M block processing L open or close message bar Delete command Insert switches to insert replacement mode Ctrl K deletes to the end of the line Ctrl Y deletes a line Homework for this section Memorize the meaning of the following control codes *[0m *[1m *[4m *[5m *[7m *[30m *[37m *[40m *[47m Write down the meaning of each of the above control codes and attach examples of their effects. *[1;32m bright green *[1;32m small handkerchief small handkerchief The specific content can be arranged at will, but each control code mentioned above must be included and written directly in the term. And pay attention to the simplification of the code. Please send a letter by month and day. Send to designated teachers of each group ANSIeditor@lily Next episode preview The basic knowledge has finally been introduced. Next, we will talk about the application of ASCIIArt.
