Add ansi codes to move cursor position: `ansi cursor_left`, `ansi
cursor_right`, `ansi cursor_up`, `ansi cursor_down`
Why I add these? I'm trying to add a spinner to the message end for a
long running task, just to find that I need to move the cursor left to
make it work as expected: `with-progress 'Waiting for the task to
finish' { sleep 10sec }`
```nu
def with-progress [
message: string, # Message to display
action: closure, # Action to perform
--success: string, # Success message
--error: string # Error message
] {
print -n $'($message) '
# ASCII spinner frames
let frames = ['⠋', '⠙', '⠹', '⠸', '⠼', '⠴', '⠦', '⠧', '⠇', '⠏']
# Start the spinner in the background
let spinner_pid = job spawn {
mut i = 0
print -n (ansi cursor_off)
loop {
print -n (ansi cursor_left)
print -n ($frames | get $i)
sleep 100ms
$i = ($i + 1) mod ($frames | length)
}
}
# Run the action and capture result
let result = try {
do $action
{ success: true }
} catch {
{ success: false }
}
# Stop the spinner
job kill $spinner_pid
print "\r \r"
# Show appropriate message
if $result.success {
print ($success | default '✓ Done!')
} else {
print ($error | default '✗ Failed!')
exit 1
}
}
```

# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.
Make sure you've run and fixed any issues with these commands:
- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use toolkit.nu; toolkit test stdlib"` to run the
tests for the standard library
> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr
> ```
