[GRASS-dev] Wingrass and TclTk

[Benjamin Ducke]

The start command does actually work to put gis.m in the background.
I changed init.bat to read:

===
rem if return ok, gis.m start:
if %errorlevel% == 2 goto exitinit

if not "%GRASS_WISH%"=="" (
  start "GIS Manager" "%GRASS_WISH%" "%WINGISBASE%\etc\gm\gm.tcl"
  winterm.bat
) else (
  start "GIS Manager" "%WINGISBASE%\etc\gm\gm.tcl"
  winterm.bat
)
===

And that works fine for me. "winterm.bat" is in GRASS/bin and has these
contents:

===
rem starts a new WinGRASS terminal window

FOR /F "usebackq delims==" %%i IN (`g.gisenv "get=LOCATION_NAME"`) DO
@set LOCATION_NAME=%%i
prompt $C%LOCATION_NAME%$F:$P $G
cd "%HOMEPATH%"

cmd.exe /C start "GRASS %GRASS_VERSION% Shell" cmd.exe /E:ON /F:ON /V:ON

exit /B
===

FWIW, I also re-designed grass63.bat to make it easier to understand and
work. If you keep it in the dir above your GRASS installation, it should
be completely relocatable, w/o having to set any vars:

===
@echo off
rem

rem ** set the name of the GRASS install dir relative to where this

rem Name of the wish (Tk) executable
set GRASS_WISH=wish.exe

rem Path to the shell command. This assumes that sh.exe is in the
subfolder "bin",
rem relative to where this batch file was started from.
set GRASS_SH=%CD%\bin\sh.exe

rem Path to your web browser (Internet Explorer by default)
set GRASS_HTML_BROWSER=%SYSTEMDRIVE%\PROGRA~1\INTERN~1\IEXPLORE.EX

rem Path to the proj files (notably the epsg projection list)
set GRASS_PROJSHARE=%CD%\share\proj

rem ** add additional paths for executables as needed **
set
PATH=%PATH%;%CD%\bin;%CD%\lib;%WINGRASS_ABS%\bin;%WINGRASS_ABS%\lib;%WINGRASS_ABS%\scripts

rem ** check if R is in the same dir and if so: expand the path **
if exist %CD%\R\bin\R.exe PATH=%PATH%;%CD%\R\bin

rem ** start main GRASS init script **
set WINGISBASE=%WINGRASS_ABS%
"%WINGISBASE%\etc\init.bat" %*

I have done some testing with all this and it seems to work fine for me,
so far.

Cheers,

Benjamin
