ANSI escape code

前一段时间在处理telnet的一些控制字符，遇到了比较纠结的事情。

自己通过socket发送命令到交换机上，获取相关字符，瞎猜，还是宣告失败，后面维基百科了一下。果然全部搞定。。。

现，献上ANSI escape code的相关解码。

 

Some ANSI escape sequences (not a complete list)CodeNameEffectCSI n ACUU – Cursor UpMoves the cursor n (default 1) cells in the given direction. If the cursor is already at the edge of the screen, this has no effect.CSI n BCUD – Cursor DownCSI n CCUF – Cursor ForwardCSI n DCUB – Cursor BackCSI n ECNL – Cursor Next LineMoves cursor to beginning of the line n (default 1) lines down.CSI n FCPL – Cursor Previous LineMoves cursor to beginning of the line n (default 1) lines up.CSI n GCHA – Cursor Horizontal AbsoluteMoves the cursor to column n.CSI n ; m HCUP – Cursor PositionMoves the cursor to row n, column m. The values are 1-based, and default to 1 (top left corner) if omitted. A sequence such as CSI ;5H is a synonym for CSI 1;5H as well as CSI 17;H is the same as CSI 17H and CSI 17;1HCSI n JED – Erase DataClears part of the screen. If n is zero (or missing), clear from cursor to end of screen. Ifn is one, clear from cursor to beginning of the screen. If n is two, clear entire screen (and moves cursor to upper left on MS-DOS ANSI.SYS).CSI n KEL – Erase in LineErases part of the line. If n is zero (or missing), clear from cursor to the end of the line. Ifn is one, clear from cursor to beginning of the line. If n is two, clear entire line. Cursor position does not change.CSI n SSU – Scroll UpScroll whole page up by n (default 1) lines. New lines are added at the bottom. (not ANSI.SYS)CSI n TSD – Scroll DownScroll whole page down by n (default 1) lines. New lines are added at the top. (not ANSI.SYS)CSI n ; m fHVP – Horizontal and Vertical PositionMoves the cursor to row n, column m. Both default to 1 if omitted. Same as CUPCSI n [;k] mSGR – Select Graphic RenditionSets SGR parameters, including text color. After CSI can be zero or more parameters separated with ;. With no parameters, CSI m is treated as CSI 0 m (reset / normal), which is typical of most of the ANSI escape sequences.CSI 6 nDSR – Device Status ReportReports the cursor position to the application as (as though typed at the keyboard) ESC[n;mR, wheren is the row and m is the column. (May not work on MS-DOS.)CSI sSCP – Save Cursor PositionSaves the cursor position.CSI uRCP – Restore Cursor PositionRestores the cursor position.CSI ?25lDECTCEMHides the cursor. (Note: the trailing character is lowercase L.)CSI ?25hDECTCEMShows the cursor.SGR (Select Graphic Rendition) parametersCodeEffectNote0Reset / Normalall attributes off1Bright (increased intensity) or Bold 2Faint (decreased intensity)not widely supported3Italic: onnot widely supported.
