installer.nsist.readme

NIST is a windows installer  (chocolatey: choco install nsis)
pynsist is a wrapper to install python apps in Windows (pip3 install pynsist).
The python app is then packed with all dipendencies including python itself in a single -installable- executable.
This is installed with few clicks.

to build the windows installer:
pynsist installer.nsist.cfg

QuangoPlus:   For correct working: the command line --tango-host=ictrlfs.ictrl.frm2:10000 
(as example) should be specified or the environment variable TANGO_HOST should be set.

To avoid the neccessity to set TANGO_HOST the quango app is started with the --tango-host option which is 
specified in the desktop shortcut by editing installer.nsi and adding 

SetOutPath "%HOMEDRIVE%\%HOMEPATH%"
     CreateShortCut "$SMPROGRAMS\QuangoPlus.lnk" "$INSTDIR\Python\pythonw.exe" \
-      '"$INSTDIR\QuangoPlus.launch.pyw"' "$INSTDIR\quango+.ico"
+      '"$INSTDIR\QuangoPlus.launch.pyw" --tango-host=ictrlfs.ictrl.frm2:10000' "$INSTDIR\quango+.ico"
   SetOutPath "$INSTDIR"


To create the tango_host.diff:  under mingw: diff -u installer.nsi installer-b.nsi >tango_host.diff

save installer.nsi and run makensis installer.nsi to build exe again with the modified shortcut.
