Get cursor position

#1 Post by Lordoa » 10 Jun 2021 13:20

Hello people,

I have this script to get the cursor position, but it is quite slow. Is there a way to make it faster, or even better, native batch?

Code: Select all

@echo off
title Get cursor
cls
setlocal enabledelayedexpansion
if not "%1" == "" goto sendenter

set strlen=for /l %%a in (1,1,2) do if "%%a" == "2" (for /f "tokens=1* delims=," %%b in ("^!args^!") do (if "%%c" == "" (set %%b=0) else ((set tmp$=%%c^& for %%p in (4096 2048 1024 512 256 128 64 32 16 8 4 2 1) do (if not "^!tmp$:~%%p,1^!" == "" (set /a len$+=%%p ^& set tmp$=^^!tmp$:~%%p^^!)))^& set %%b=^^!len$^^!))) else set len$=1^&set args=
FOR /F "delims=#" %%a IN ('"prompt #$E# & for %%a IN (1) do rem"') do set esc=%%a
:menu
echo(
echo(
echo(
pause>nul|set/p =Fourth line, 29th character:
<nul set/p=%esc%[6n
start /b "" "%cd%\%~nx0" cookie
set /p cursorloc=
echo Did it work?
%strlen%result,%cursorloc%
echo %result%
for /f "tokens=1,2,3 delims=[]R;" %%a in ("%cursorloc%") do echo %%b and %%c
pause

:sendenter
powershell -nologo $wshell = New-Object -ComObject wscript.shell; $wshell.Sendkeys('~')
exit
Ty,
Lordoa

No. But why so complicated? You use PowerShell anyway.

Code: Select all

@echo off
title Get cursor
echo(
echo(
echo(
pause>nul|set/p =Fourth line, 29th character:
for /f "tokens=1*" %%i in (
  'powershell.exe -nop -ep Bypass -c "$pos=$host.UI.RawUI.CursorPosition;(''+($pos.X+1)+' '+($pos.Y+1))"'
) do echo line %%j, character %%i
pause
Note that I add 1 to the X and Y position each, just to meet your expectations. Actually that's wrong because coordinates are zero-based. The origin of the console window is {0,0] rather than {1,1}.

Definitely might use that. :D
You potentially only need to run powershell once

I figured there existed a powershell one-liner to get cursor position, but I was kind of hoping for a native batch way to insert an {ENTER} (to store cursor location in set /p). For example getting the enter key using prompt $_ (but I have no clue how to do that). I'd also be able to use the former in some others uses, like automation.
ANSI syntax has a [1,1] origin,

Thanks,
Lordoa

Thanks to jeb, the cursor position could be read using the vt100 functionality with pure batch:
viewtopic.php?f=3&t=9454&p=61318#p61322

Sidenote: You could do the same using C# to compile an executable file, which is done in the first post...
but then you better might write a c# exe that accesses those information without the need of vt100 sequences.

For pure batch, without powershell, It is much more efficient to use variable tracking of cursor movements than it is to capture and compare the current cursor position - even if you need to perform string length calculations in conjuction with set /a modification to y;x axis variables, you'll still be able to track position much faster than the loop sequence Jeb designed to capture cursor position.

Cursor positioning is indexed from 1;1 - after performing a cls the cursor will be positioned here.
Relative cursor positioning: https://docs.microsoft.com/en-us/window ... ositioning

Out of curiosity, what use case do you think you need the cursor position for?

You may use my CursorPos.exe auxiliary program to both get and set cursor position. Download it from Advanced Batch features via auxiliary .exe programs.

You will also get a lot of useful auxiliary programs, like GetKey.exe, ColorShow.exe, printf.exe, etc...
