NAME
mdoc update - mdoc(5) documentation format support
SYNOPSIS
mdoc update [OPTIONS]* ASSEMBLIES
DESCRIPTION
mdoc update is responsible for the following:
* Creating documentation stubs based on ASSEMBLIES. The stub-cre-
ation process will create new mdoc(5) XML files for each type
within ASSEMBLIES, and provide documentation stubs for each mem-
ber of those types.
* Update documentation stubs based on ASSEMBLIES. Existing
mdoc(5) documentation can be updated to reflect changes within
ASSEMBLIES, such as added types and members, while preserving
existing documentation.
In some limited circumstances, renames will be tracked, minimiz-
ing the documentation burden when e.g. a parameter is renamed.
mdoc update does not rely on documentation found within source code,
though it can import XML Documentation Comments via the -i option.
See mdoc(1) and mdoc(5) for more information.
OPTIONS
--delete
Allow mdoc update to delete members from documentation files.
The only members deleted are members which are no longer present
within ASSEMBLIES and are not present in any other assembly ver-
sions.
If a type is no longer present, the documentation file is not
deleted, but is instead renamed to have a .remove extension.
Version detection is done with the //AssemblyVersion elements;
if there are no //AssemblyVersion elements for a given <Type> or
<Member/>, then the <Type> will be renamed and/or the <Member/>
will be removed.
--exceptions[=SOURCES]
EXPERIMENTAL. This is not 100% reliable, but is intended to
serve as an aid for documentation writers.
Inspect member bodies to determine what exceptions can be gener-
ated from the member.
SOURCES is an optional comma-separated list of the following
sources that should be searched for exceptions:
added Only generate <exception/> elements for members
added during the current program execution.
This keeps mdoc-update from re-generating
<exception/> elements for all members (and thus
prevents re-insertion for members that had the
<exception/> elements removed).
all Find exceptions created in the member itself,
references to members in the same assembly,
and references to members in dependent
assemblies.
asm Find exceptions created in the member itself and
references to members within the same assembly
as the member.
depasm Find exceptions created in the member itself and
references to members within dependent
assemblies.
If SOURCES isn't provided (the default), then only exceptions
created within the member itself will be documented.
LIMITATIONS: Exception searching is currently implemented by
looking for the exception types that are explicitly created
based on the known compile-time types. This has the following
limitations:
* This will not find exceptions which are implicit to the
IL, such as NullReferenceException and IndexOutOfRangeEx-
ception.
* This will find exceptions which are not thrown, e.g.
public void CreateAnException ()
{
Exception e = new Exception ();
}
* This will not "follow" delegate and interface calls:
public void UsesDelegates ()
{
Func<int, int> a = x => {throw new Exception ();};
a (4);
}
The function UsesDelegates() won't have any exceptions
documented.
* This will find exceptions which "cannot happen", such as
ArgumentNullExceptions for arguments which are "known" to
be non-null:
public void A ()
{
B ("this parameter isn't null");
}
public void B (string s)
{
if (s == null)
throw new ArgumentNullException ("s");
}
For the above, if --exceptions=asm is provided then A()
will be documented as throwing an ArgumentNullException,
which cannot happen.
-f=FLAG
Specify a flag to alter behavior. Valid flags include:
no-assembly-versions
See the -fno-assembly-versions documentation, below.
-fno-assembly-versions
Do not generate /Type/AssemblyInfo/AssemblyVersion and
/Type/Members/Member/AssemblyInfo elements.
This is useful to prevent "churn" during updates. Normally, if
a type or member hasn't changed but the assembly version has
changed, then all types and members will be updated to include a
new //AssemblyVersion element, thus increasing the amount of
changes that need review before committing (assuming all changes
are actually reviewed before commit).
WARNING: This will interact badly with the --delete option, as
--delete uses the //AssemblyVersion elements to track version
changes. Thus, if you have a member which is present in an
early assembly version and is removed in a subsequent assembly
version, such as System.Text.UTF8Encoding.GetBytes(string)
(which is present in .NET 1.0 but not in .NET 2.0), then the
member will be removed when the --delete -fno-assembly-versions
options are specified, the member was present in an earlier ver-
sion of the assembly, and the current version of the assembly
does not contain the member.
Consequently, this option should only be specified if types and
members will never be removed from an assembly.
-i, --import=FILE
Import documentation found within FILE.
FILE may contain either csc /doc XML or ECMA-335 XML.
-L, --lib=DIRECTORY
Add DIRECTORY to the assembly search path, so that dependencies
of ASSEMBLIES can be found without documenting those assemblies.
-o, --out=DIRECTORY
Place the generated stubs into DIRECTORY.
When updating documentation, DIRECTORY is also the source direc-
tory.
-r=ASSEMBLY
ASSEMBLY is a dependency for one of ASSEMBLIES which should not
be documented but is required to process one of ASSEMBLIES. Add
the directory containing ASSEMBLY to the assembly search path.
This option is equivalent to specifying -L `dirname ASSEMBLY`.
--since=VERSION
When updating documentation for an assembly, if a type or member
is encountered which didn't exist in the previous version of the
assembly a <since version="VERSION"/> element will be inserted.
--type=TYPE
Only update documentation for the type TYPE.
-h, -?, --help
Display a help message and exit.
