A batch menu select

#1 Post by einstein1969 » 11 May 2014 18:14


I have started to implement a function that is inspired at the cmdmenusel found on the Judago's site.

It is the skeleton or a proof of concept.

I have used native dos command!

I stopped this a long time. If someone wants to improve it ...

Code: Select all

@echo off & setlocal EnableDelayedExpansion & Goto :Init_system


cls & mode %cols%,%lines% & color

rem default color E2F4
rem exitcode return the position selected

set /a sel=2, oldsel=2
set Num=9
For /L %%O in (1,1,%num%) do set "opt%%O=Option %%O"

mode %cols%,%lines%

echo Menu %sel%
echo ----
For /L %%O in (1,1,%num%) do (
  <nul set /p "=%DEL% "
  if !sel! equ %%O (call :colorText E8 "-!opt%%O!-" & call :ColorText_bg_BS E %cols%-13 /n
     ) else (
         if !oldsel! equ %%O (
                call :colorText 8E " !opt%%O!" & call :ColorText_bg_BS 8 %cols%-12 /n
         ) else call :colorText 8E " !opt%%O!" /n
set /a "oldsel=sel, sel=(sel %% num)+1"
goto :menu

goto :End_Main

 <nul set /p ".=%BS%"> "%~2"
 findstr /v /a:%1 /R "^$" "%~2" nul
 rem del "%~2" > nul 2>&1
 if /i "%~3"=="/n" echo(
goto :eof

:ColorText_bg_BS bg_color len [/n]
  set /a "len=%2-1"
  if !len! geq 1 for %%. in (!len!) do  findstr /v /a:%1%1 /R "^$" "!str_findstr:~0,%%.!" nul
  if /i "%~3"=="/n" echo(
goto :eof


rem change to temp dir
pushd "%temp%"

for /f %%a in ('copy /Z "%~dpf0" nul') do set "CR=%%a"

rem make DEL
for /F "tokens=1,2 delims=#" %%a in ('"prompt #$H#$E# & echo on & for %%b in (1) do rem"') do (
  set "DEL=%%a"

:: Define BS to contain a backspace
for /f %%a in ('"prompt $H&for %%b in (1) do rem"') do set "BS=%%a"

rem screen widht
set /a cols=78, lines=43

rem make a string with len %cols% cars

set "str_findstr="
For /L %%c in (1,1,%cols%) do set "str_findstr=!str_findstr!L"

rem male all lenght possibles, for speedup findstr

For /L %%l in (1,1,%cols%) do <nul set /p .=%BS%> "!str_findstr:~0,%%l!"

goto :Main

  rem remove the temporary files... TODO!
Goto :eof
