The current doc generation doesn't care much about indentation levels,
but we would like to switch to an rST format, and rST does care about
indentation.
Make the doc comments more strongly consistent about indentation
for multiline constructs like:
@arg: description line 1
description line 2
Returns: line one
line 2
so that there is always exactly one space after the colon, and
subsequent lines align with the first.
This commit is a purely whitespace change, and it does not alter the
generated .texi files (because the texi generation code strips away
all the extra whitespace). This does mean that we end up with some
over-length lines.
Note that when the documentation for an argument fits on a single
line like this:
@arg: one line only
then stray extra spaces after the ':' don't affect the rST output, so
I have not attempted to methodically fix them, though the preference
is a single space here too.

# @ObjectPropertyInfo:

|
|
# @name: the name of the property

|
#
|
|
# @type: the type of the property. This will typically come in one of four
|
|
# forms:
|
|
#
|
|
# 1) A primitive type such as 'u8', 'u16', 'bool', 'str', or 'double'.

# These types are mapped to the appropriate JSON type.

|
|
# 2) A child type in the form 'child<subtype>' where subtype is a qdev

# device type name. Child properties create the composition tree.
|
|
#
|
|
# 3) A link type in the form 'link<subtype>' where subtype is a qdev
|

# device type name. Link properties form the device model graph.

# @description: if specified, the description of the property.

# @qom-get:
|
|
#
|
|
# This command will get a property from a object model path and return the
|
|
# value.
|
|
#
|
|
# @path: The path within the object model. There are two forms of supported
|
|
# paths--absolute and partial paths.
|
|
#
|
|
# Absolute paths are derived from the root object and can follow child<>
|
|
# or link<> properties. Since they can follow link<> properties, they
|
|
# can be arbitrarily long. Absolute paths look like absolute filenames
|
|
# and are prefixed with a leading slash.
|
|
#
|
|
# Partial paths look like relative filenames. They do not begin
|
|
# with a prefix. The matching rules for partial paths are subtle but
|
|
# designed to make specifying objects easy. At each level of the
|
|
# composition tree, the partial path is matched as an absolute path.
|
|
# The first match is not returned. At least two matches are searched
|
|
# for. A successful result is only returned if only one match is
|
|
# found. If more than one match is found, a flag is return to
|
|
# indicate that the match was ambiguous.
|
|
#
|
|
# @property: The property name to read
|
|
#
|
|
# Returns: The property value. The type depends on the property
|
|
# type. child<> and link<> properties are returned as #str
|
|
# pathnames. All integer property types (u8, u16, etc) are
|
|
# returned as #int.
|
|
#
|
|
# Since: 1.2
