Does it require a difference (for the C++ front ends) to add support
for FTP InstallMgr methods than it does for them to add a file://
version? It seems that, if so, this is a problem with the design of
InstallMgr. I would imagine that the interface between SWORD and
the
application would be identical in all those cases -- all the
application needs is to retrieve the information and provide a way
for
the user to input new locations. I get the impression from your
previous messages that the front ends will need to change when you
add
HTTP support to the library then front ends will need to add another
portion to their install manager that allows the user to create HTTP
install locations separate from FTP or file:// ones -- is that the
case?
The interface is different for local installations than it is for FTP
installations. For local installations, you must create an SWMgr that
points to the location of the modules to be installed, then you can
get a listing of the modules available (but you must be careful to
not
augment the path with HOME/.sword or other locations or it won't
work). For FTP, it also creates an SWMgr, but it does it itself, and
exposes the list of available modules. This difference is why Xiphos
couldn't really use a local source until 3.0. No one had figured out
how it was supposed to work :)
I see -- it seems to me that method doesn't take nearly as much
abstraction as it should. I should imagine that a client application
could simply create an InstallMgr object and pass it the string that
it ought to search for. If the string is file://, ftp://, http://,
cifs:// or \\host or whatever shouldn't much matter in my mind. The
URI should be parsed and the proper actions taken within InstallMgr.
Yeah. I second that.
For any install source location InstallMgr should be used and it
should be able to handle any URL.
