Hi, I wanted to use a hierarchy of argp parsers in the console server, one in each driver module, one for focus groups, one for consoles, and one for the main program. However, argp parents and childs shade the options of other childs, in the sense that argp calls only one parser for each recognized option. It is not possible to have common options in different parsers this way (I wanted to enable/disable parsers in parent parsers).
So what I want to do now is to do the recursion manually, so that when a new input device is configured, the input device parser is run which parses as much on the command line as it can, and then returns back, where parsing in the other parser is continued. This might actually be cleaner and easier to implement anyway. From a quick glance, argp seems to be reentrant, is this really true? Are there any (better) alternatives? Note: pfinet would have the same problem, except that it avoids it by lack of modularity. libstores would have the same problem except it avoids it by lack of flexibility (all arguments for a store are encoded in the store name). I think both are not acceptable work arounds here, because drivers are platform specific and complex. Here is an example potential console command line I have in mind: /hurd/console --encoding isolat1 --console maincons --output-device vga \ --vt 1 --encoding utf8 \ --focus-group mainfocg --focus maincons --input-device pckbd --layout de \ --input-device mouse --name mouse1 --device /dev/ttyS0 --protocol mouseman (Don't be scared, some of these will already be the default). Or, for example, to remove the mouse: fsysopts /node --remove mouse1 To use isolat9 on virtual console 2: fsysopts /node --console maincons --vt 2 --encoding isolat9 (or maybe even "fsysopts /node/maincons/2 --encoding isolat9") (If you have better ideas instead of the option marathon, let me know).
