Examples
Setting Cursor Position and Writing Text:

Moving Cursor Relative to Current Position:
curs_inwstr -m relative -o
UP 2
RIGHT 5
echo "Cursor moved up 2 and right 5"
Advanced Scripting:

while true; do
curs_inwstr -d 10000 -o

Common Issues
- Errors may occur if the terminal does not support cursor control.
- Color output may not work on all terminals.
- Relative cursor movements may not function correctly in some shells.
Integration
curs_inwstr
can be integrated with other commands using pipes or scripts. For example:
printf "Text" | curs_inwstr -d 100000 -c | cat -
pipes the output from printf
through curs_inwstr
and displays it slowly using cat
.
