Thread: How to handle long lines using GNU readline?

Hey there. I implemented a small command line interpreter using the GNU readline library. This works really nice except for lines having much text input. As soon as the user reaches the console width the readline command prompt within the same line gets overwritten. What I want is the line to wrap around automatically. For example:

Code:

cli> this is some very long line which should wrap around
 to the next line

instead of

Code:

 to the next line very long line which should wrap around

Is there a way to do that? Thanks in advance.

You are right. This only happens when using a colored command line:

Code:

//input = readline("cli> ");			// Works
input = readline("\033[1;37mcli>\033[0m ");	// Works not

Hrm.

I can't tell for sure, but I know color prompts caused trouble in terminals with long lines from day 0 (at least for me). Maybe the problem is in "\033[0m" which resets stuff. Try replacing it with ansi code to change color to previous one, not to reset anything.

Thanks, but I already tried that before. Even a fully colored prompt misbehaves.
