       mdoc update - mdoc(5) documentation format support


       mdoc update [OPTIONS]* ASSEMBLIES


       mdoc update is responsible for the following:

       *      Creating  documentation  stubs  based  on ASSEMBLIES.  The stub-
              creation process will create new mdoc(5) XML files for each type
              within  ASSEMBLIES,  and  provide  documentation  stubs for each
              member 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,
              minimizing the documentation burden when  e.g.  a  parameter  is

       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.


              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

              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.

              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
              generated 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
                      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

              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

              *      This will not find exceptions which are implicit  to  the
                     IL,      such      as      NullReferenceException     and

              *      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

              *      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.

              Specify a flag to alter behavior.  Valid flags include:

                     See the -fno-assembly-versions documentation, below.

              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
              version 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

              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`.

              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.

              Only update documentation for the type TYPE.
