Terminal control/Restricted width positional input/No wrapping: Difference between revisions

=={{header|Nim}}==

{{trans|Julia}}

As in the Julia version we translated, the code is identical to the code in [[Terminal_control/Restricted_width_positional_input/No_wrapping]] but with no width argument in the input call. See this version for some general comments about the code.

<lang Nim>import strformat, terminal

proc eraseLineEnd() = stdout.write("\e[K")

proc inputXYUpto(row, col, cmax: int; width = cmax): string =

while result.len < cmax and not ((let c = getch(); c) in ['\xff', '\f', '\r']):

setCursorPos(row, col)

eraseLineEnd()

if c in ['\b', '\x7f'] and result.len > 0:

result.setLen(result.len - 1)

else:

result.add c

stdout.write result[(if result.len > width: result.len - width else: 0)..result.high]

eraseScreen()

setCursorPos(3, 5)

let s = inputXYUpto(3, 5, 8)

echo &"\n\n\nResult: You entered <<{s}>>"</lang>
