Hi all,
The attached patch (diff against cvs version) fixes two trivial bugs
in ScriptHappy. The remaining patch is a hopefully decent basis for
the Win32 version of the plugin. It appears to work for me under
Windows 2000 (also a quick test done on Windows 95 OSR2)
The Win32 version will only retrieve output if the program being
spawned actually writes to StdOut, many programs on Windows do not
meet this criteria. Depending on the program, AbiWord will appear
locked up until the spawned program terminates (while Abi's blocked
waiting on data to be read); some GUI programs can be spawned this
way and AbiWord will continue along, others AbiWord will freeze
until the spawned GUI program terminates (eg Write vs Winzip).
I believe many console programs will work fine (not DOS ones though,
I had mistaken this earlier, I was running a dual Win/DOS exe). The
spawned application should not need any input from the user via stdin. I
think the unix version of the plugin also has this limit, although
I don't believe it would be too hard to support sending data to
the spawned program's stdin, I have no idea where to get that data
from. The only major thing I can see (and I could easily be overlooking
some) is that popen invokes %shell% /c 'command' whereas I currently
just invoke 'command' so only *.com, *.exe, and *.bat are supported.
I think, but not sure without testing something like this will work:
..
if ((cmdshell=getenv("COMSPEC") != NULL)
command = cmdshell + " /C " + command;
else
if (OS == NT)
command = "cmd.exe /C " + command;
else // OS == 9x
command = "command.com /C " + command;
..
Anyway its here to play with (binary can be gotten from darklogic site).
If anyone knows of a better way to do this, please let me know, I
really didn't have a clue when I started so this is based on a quick
search of the Win32 api docs. [I did 1st try _popen and it didn't
seem to work, perhaps I missed something there.] Otherwise please
consider committing some form of it.
Thanks,
Jeremy Davis
