Suggested REXX APIs
Abort WPI
Deinstall packages
query if package is installed
query the files of a package
query WarpIN language
query Locale language
New attributes for PCK tag
execute program from package as sniffer
Requirement:
- run a program, included in the WPI archive, to determine if a prerequisite for installation is met
- continue installation with no message on zero reason code
- display a message for specific error code(s) and abort installation
Used Case:
- installation of device drivers: sniffer for hardware (e.g. check for a PCI device)
- installation of Wireless LAN Monitor: determnine active instance of xCenter
Current workaround:
- can be done by REXX, extracting a hidden package to a temp directory. However, the WPI cannot be aborted by REXX code
Suggested Change:
- additional attribute PREEXECUTE for PKG tag like (DE)EXECUTE
Problem:
- no idea yet how to define the message(s) being displayed on error, possibly <ERRORMSG rc=n>as counterpart to MSG, where <ERRORMSG> with no rc would be the default error msg.
hide a package
autodeinstall any older/other version of a PCK
execute a program/REXX code before/after executing any installation action
exit for rc!=0
force a kill of a program without prompt
force unlock of a executable without prompt
Parameters to WARPIN.EXE
deinstall a PACKAGE, supporting wildcards
allows WPS object to deinstall a program
