# Carriage Return (CR)

<VTSequence sequence="CR" />
|
|
|
|
Move the cursor to the leftmost column.
|
|
|
|
This sequence always unsets the pending wrap state.
|
|
|
|
If [origin mode (mode 6)](#TODO) is enabled, the cursor is set to the
|
|
[left margin](#TODO) of the scroll region and the operation is complete.
|
|
|
|
If origin mode is _not_ set and the cursor is on or to the right of the
|
|
left margin, the cursor is set to the left margin. If the cursor is to the left
|
|
of the left margin, the cursor is moved to the leftmost column in the terminal.

|
|
|
## Validation

### CR V-1: Pending Wrap is Unset
|
|
|
|
```bash
|
|
cols=$(tput cols)
|
|
printf "\033[${cols}G" # move to last column
|
|
printf "A" # set pending wrap state
|
|
printf "\r"
|
|
printf "X"
|
|
echo
|
|
```
|
|
|
|
```
|
|
|X________A|
|
|
|c_________|
|
|
```
