I'm trying to organize the parameters into a tree structure instead of
|
|
a huge flat list. Once the parameter code is improved, I hope to use
|
|
parameters to implement save/restore, and to give access to device
|
|
state from within the debugger.

Notes:
|
|
- get rid of bx_id enumerated type and parameter id numbers (e.g.
|
|
BXP_FLOPPYA_PATH) These id numbers are ok for scalar parameters like
|
|
"memory size in megabytes" but very bad for parameters of replicated
|
|
devices, like com1,2,3,4, ata1,2,3,4, with master and slave, etc. The only
|
|
reason that we have id numbers at all is to be able to find the pointer to a
|
|
parameter. In a tree structure, the parameters will be found by name
|
|
instead.
|
|
- when creating a bx_param_c object, specify the parent object. The
|
|
parent must be bx_list_c type. In the constructor, the child is
|
|
added to the parent's list of children, and (optionally) the child
|
|
keeps a pointer to the parent.
|
|
- parameters can then be located by their position in the tree, for
|
|
example: memory.rom.address. That means to find the bx_list_c called
|
|
"memory" in the list of top level objects, then get the bx_list_c called
|
|
"rom" in memory's list of children, then get the child called "address"
|
|
in rom's list of children.
|
|
- alternative notation: memory/rom/address, ata>1>slave>cylinders,
|
|
memory'optional_rom'path
|
|
|
|
- parameters have additional information inside them, like the name,
|
|
description, min, max, initial value. Do we need a way to name
|
|
this stuff? Invent syntax.... PARAM'FIELD means field FIELD of parameter
|
|
PARAM.
|
|
memory.ram.size = 32
|
|
memory.ram.size'type = BXT_PARAM_NUM
|
|
memory.ram.size'max = 4
|
|
memory.ram.size'min = 256
|
|
memory.ram.size'initial_value = 256
|
|
memory.ram.size'parent refers to parameter memory.ram
|
|
memory.ram'parent refers to parameter memory
|
|
etc.
|
|
I'm not sure if this will ever be needed.
|
|
- also I don't know if any form of relative pathname would be useful/needed.
|
|
If so, probably using slash notation and ".."'s would look the most
|
|
familiar to people.
|
|
- we need to be able to handle arrays of objects, but I think it can be
|
|
done with just another list with names 0, 1, 2, 3, etc.

|
- I have written all the parameter names in "C variable name" style,
|
|
lowercase with underscores instead of spaces. But for display purposes
|
|
it may be k
