Denis Vlasenko | 78ff819 | 2008-06-28 21:03:43 +0000 | [diff] [blame] | 18 | * Usage and known bugs: |
| 19 | * Terminal key codes are not extensive, and more will probably |
| 20 | * need to be added. This version was created on Debian GNU/Linux 2.x. |
| 21 | * Delete, Backspace, Home, End, and the arrow keys were tested |
| 22 | * to work in an Xterm and console. Ctrl-A also works as Home. |
| 23 | * Ctrl-E also works as End. |
| 24 | * |
| 25 | * lineedit does not know that the terminal escape sequences do not |
| 26 | * take up space on the screen. The redisplay code assumes, unless |
| 27 | * told otherwise, that each character in the prompt is a printable |
| 28 | * character that takes up one character position on the screen. |
| 29 | * You need to tell lineedit that some sequences of characters |
| 30 | * in the prompt take up no screen space. Compatibly with readline, |
| 31 | * use the \[ escape to begin a sequence of non-printing characters, |
| 32 | * and the \] escape to signal the end of such a sequence. Example: |
| 33 | * |
| 34 | * PS1='\[\033[01;32m\]\u@\h\[\033[01;34m\] \w \$\[\033[00m\] ' |
