ANSI/VT100 Terminal Control Escape Sequences

　　你知道吗，用 printf 打印一些特殊字符序列可以实现对终端的控制哎～（如终端背景色，前景色，清屏，状态设置……），由于资料不是太多，稍微整理了一下！(试了下，在win 下不起作用！) 原址： http://www.termsys.demon.co.uk/vtansi.htm

一、前言

Many computer terminals and terminal emulators support colour and cursor control through a system of escape sequences. One such standard is commonly referred to as ANSI Colour. Several terminal specifications are based on the ANSI colour standard, including VT100.

The following is a partial listing of the VT100 control set.

<ESC> represents the ASCII "escape" character, 0x1B, \033. Bracketed tags represent modifiable decimal parameters; eg. {ROW} would be replaced by a row number.

 

二、设置选项目录 

[ Status | Setup | Fonts | Cursor | Scrolling | Tabs | Erasing | Printing | Keyboard | Colours ]

1.Device Status

The following codes are used for reporting terminal/display settings, and vary depending on the implementation:
Query Device Code <ESC>[c
Requests a Report Device Code response from the device（我的电脑为 62;9;c）.

Report Device Code <ESC>[{code}0c
Generated by the device in response to Query Device Code request.

Query Device Status <ESC>[5n
Requests a Report Device Status response from the device.

Report Device OK <ESC>[0n
Generated by the device in response to a Query Device Status request; indicates that device is functioning correctly.

Report Device Failure <ESC>[3n
Generated by the device in response to a Query Device Status request; indicates that device is functioning improperly.

Query Cursor Position <ESC>[6n
Requests a Report Cursor Position response from the device.

Report Cursor Position <ESC>[{ROW};{COLUMN}R
Generated by the device in response to a Query Cursor Position request; reports current cursor position.

2.Terminal Setup

The h and l codes are used for setting terminal/display mode, and vary depending on the implementation. Line Wrap is one of the few setup codes that tend to be used consistently:

Reset Device <ESC>c
Reset all terminal settings to default.

Enable Line Wrap <ESC>[7h
Text wraps to next line if longer than the length of the display area.

Disable Line Wrap <ESC>[7l
Disables line wrapping.

3.Fonts

Some terminals support multiple fonts: normal/bold, swiss/italic, etc. There are a variety of special codes for certain terminals; the following are fairly standard:

Font Set G0 <ESC>(
Set default font.

Font Set G1 <ESC>)
Set alternate font.

4.Cursor Control

Cursor Home <ESC>[{ROW};{COLUMN}H
Sets the cursor position where subsequent text will begin. If no row/column parameters are provided (ie.<ESC>[H), the cursor will move to the home position, at the upper left of the screen.

Cursor Up <ESC>[{COUNT}A
Moves the cursor up by COUNT rows; the default count is 1.

Cursor Down <ESC>[{COUNT}B
Moves the cursor down by COUNT rows; the default count is 1.

Cursor Forward <ESC>[{COUNT}C
Moves the cursor forward by COUNT columns; the default count is 1.

Cursor Backward <ESC>[{COUNT}D
Moves the cursor backward by COUNT columns; the default count is 1.

Force Cursor Position <ESC>[{ROW};{COLUMN}f
Identical to Cursor Home.

Save Cursor <ESC>[s
Save current cursor position.

Unsave Cursor <ESC>[u
Restores cursor position after a Save Cursor.

Save Cursor & Attrs <ESC>7
Save current cursor position.

Restore Cursor & Attrs <ESC>8
Restores cursor position after a Save Cursor.

5.Scrolling

Scroll Screen <ESC>[r
Enable scrolling for entire display.

Scroll Screen <ESC>[{start};{end}r
Enable scrolling from row {start} to row {end}.

Scroll Down <ESC>D
Scroll display down one line.

Scroll Up <ESC>M
Scroll display up one line.

6.Tab Control

Set Tab <ESC>H
Sets a tab at the current position.

Clear Tab <ESC>[g
Clears tab at the current position.

Clear All Tabs <ESC>[3g
Clears all tabs.

7.Erasing Text

Erase End of Line <ESC>[K
Erases from the current cursor position to the end of the current line.

Erase Start of Line <ESC>[1K
Erases from the current cursor position to the start of the current line.

Erase Line <ESC>[2K
Erases the entire current line.

Erase Down <ESC>[J
Erases the screen from the current line down to the bottom of the screen.

Erase Up <ESC>[1J
Erases the screen from the current line up to the top of the screen.

Erase Screen <ESC>[2J
Erases the screen with the background colour and moves the cursor to home.

8.Printing

Some terminals support local printing:
Print Screen <ESC>[i
Print the current screen.

Print Line <ESC>[1i
Print the current line.

Stop Print Log <ESC>[4i
Disable log.

Start Print Log <ESC>[5i
Start log; all received text is echoed to a printer.

9.Define Key

Set Key Definition <ESC>[{key};"{string}"p
Associates a string of text to a keyboard key. {key} indicates the key by its ASCII value in decimal.

10.Set Display Attributes

Set Attribute Mode <ESC>[{attr1};...;{attrn}m
Sets multiple display attribute settings. The following lists standard attributes:
0 Reset all attributes  关闭所有属性
1 Bright 
2 Dim
4 Underscore  下划线
5 Blink           闪烁
7 Reverse       反显
8 Hidden        消隐

Foreground Colours
30 Black
31 Red
32 Green
33 Yellow
34 Blue
35 Magenta     紫
36 Cyan          深绿
37 White

Background Colours（颜色对应前景色一样）
40 Black
41 Red
42 Green
43 Yellow
44 Blue
45 Magenta
46 Cyan
47 White

（注：有些字符序列貌似不是太通用，支持不太好！）

 

三、实战

1.清屏

printf("\033[1H\033[2J");      #操作光标实现

2.设置前景及背景色

printf("\033[43;31mhello world\033[0m");
