NAME

       yangdump - validate YANG modules and convert them to different formats

SYNOPSIS

          yangdump (module=value | subtree=value)+ [parameter=value...]

          yangdump  --help [brief | normal | full]

          yangdump  --version

          yangdump  --show-errors

DESCRIPTION

       yangdump  provides  validation  and  translation of YANG data models.  Information about a
       module or submodule can be generated as well.  This version of yangdump supports the  YANG
       data modeling language defined in RFC 6020.

       The  format parameter is used to select a translation output mode.  If it is missing, then
       no translation will be done.

       This parameter can be used with the module reports parameters, but the translation  output
       should be directed to a file instead of STDOUT to keep them separated.

       For XSD 1.0 translation, use the format=xsd parameter.

       For XHTML 1.0 translation, use the format=html parameter.

       For a 1 line output of the module name and version, use the modversion parameter.

       For  a  listing  of  all the symbols that the file exports to other files, use the exports
       parameter.

       For a listing of all the files that the file depends on, to compile, use the  dependencies
       parameter.

       For  a  listing  of  all the accessible object identifiers that the file contains, use the
       identifiers parameter.

       For a listing of all the accessible object identifiers that the  file  contains,  in  tree
       format, use the tree-identifiers parameter.

USAGE

       Parameters can be entered in any order, and have the form:

          [start] name [separator [value]]

       where:

           start == 0, 1, or 2 dashes (foo, -foo, --foo)

           name == parameter name

                Parameter name completion will be attempted
                if a partial name is entered.

           separator == whitespace or equals sign (foo=bar, foo bar)

           value == string value for the parameter.

                Strings with whitespace need to be double quoted
                (--foo="some string")

       Some examples of valid command line parameters:

          foo=3
          -foo=3
          --foo=3
          foo 3
          foo=fred
          --foo "fred flintstone"

       Partial parameter names can be entered if they are unique.

OPTIONS

--config=filespec
The name of the configuration file to use. Any parameter except this one can be
set in the config file. The default config file /etc/yuma/yangdump.conf will be
not be checked if this parameter is present.

--defnames=boolean
If true, output to a file with the default name for the format, in the current
directory. The default value is 'false'.

If the output parameter is present and represents an existing directory, then the
default filename will be created in that directory, instead of the current
directory.

--dependencies
Validate the file, write the module name, version and module source for each file
that this [sub]module imports and includes, then exit.

Each dependency type, name, version, and source is listed once.

If the dependency version and source are missing, then that import or include file
was not found.

--deviation=string
This parameter identifies a YANG module that should only be checked for deviation
statements for external modules. These will be collected and applied to the real
module(s) being processed.

Deviations are applied as patches to the target module. Since they are not
identified in the target module at all (ala imports), they have to be specified
explicitly, so they will be correctly processed. Zero or more instances of this
parameter are allowed.

--exports
Validate the file, write information for the symbols that this [sub]module exports,
then exit. Report includes the following info for the specific file, not the
entire module, if submodules are used:

- [sub]module name
- version
- source filespec
- namespace (module only)
- prefix (module only)
- belongs-to (submodule only)
- typedefs
- groupings
- objects, rpcs, notifications
- extensions.

--feature-code-default=enum
If 'dynamic' (the default), then dynamic SIL feature code will be generated by
default. If 'static', then static SIL feature code will be generated by default.
If false, then features will be disabled by default.

--feature-disable=module:feature
Identifies a feature which should be considered disabled.

--feature-dynamic=module:feature
Identifies a dynamic feature for SIL code generation purposes. Zero or more
entries are allowed.

--feature-enable-default=boolean
If true (the default), then features will be enabled by default. If false, then
features will be disabled by default.

--feature-enable=module:feature
Identifies a feature which should be considered enabled. Zero or more entries are
allowed.

--feature-static=module:feature
Identifies a static feature for SIL code generation purposes. Zero or more entries
are allowed.

--format=string
Type of conversion desired, if any. If this parameter is missing, then no
translation will be done, but the module will be validated, and any requested
reports will be generated.

The following translation formats are available:

xsd: XSD 1.0
html: XHTML 1.0
yang: Canonical YANG (in progress)
copy: Validate, and copy with a new name
yin: YIN format
c: Combined Yuma and User SIL C module
h: Combined Yuma and User SIL H file
uc: User part of a split SIL C module
uh: User part of a split SIL H file
yc: Yuma part of a split SIL C module
yh: Yuma part of a split SIL H file

--help Print this help text and exit. The help-mode choice (--brief, --normal, or --full)
may also be present to control the amount of help text printed.

--home=dirspec
Directory specification for the home directory to use instead of HOME.

--html-div
If HTML translation is requested, then this parameter will cause the output to be a
single <div> element, instead of an entire HTML file. This allows the HTML
translation to be easily integrated within more complex WEB pages, but the proper
CSS definitions need to be present for the HTML to render properly.

The default filename extension will be '.div' instead of '.html' if this parameter
is present. The contents will be well-formed XHTML 1.0, but without any namespace
declarations.

--html-toc=string
The HTML Table of Contents output mode. Ignored unless the format parameter is set
to html. Default is menu.

Values:

- none: no ToC generated
- plain: plain list ToC generated
- menu: drop-down menu ToC generated.

--identifiers
Validate the file, write the list of object identifiers, that this [sub]module
contains, then exit.

Each accessible object node is listed once, including all child nodes.
Notifications and RPC methods are considered top-level objects, and have object
identifiers as well as configuration and state data..

--indent=number
Number of spaces to indent (0..9) in formatted output. The default is 2 spaces.

--log=filespec
Filespec for the log file to use instead of STDOUT. If this string begins with a
'~' character, then a username is expected to follow or a directory separator
character. If it begins with a '$' character, then an environment variable name is
expected to follow.

--log-append
If present, the log will be appended not over-written. If not, the log will be
over-written. Only meaningful if the log parameter is also present.

--log-level=enum
Sets the debug logging level for the program.

--modpath=list
Directory search path for YANG and YIN files. Overrides the YUMA_MODPATH
environment variable.

--module=string
YANG or YIN source module name to validate and convert.

If this string represents a filespec, ending with the .yang or .yin extension, then
only that file location will be checked.

If this string represents a module name, then the module search path will be
checked for a file the .yang or .yin extension.

If this string begins with a '~' character, then a username is expected to follow
or a directory separator character. If it begins with a '$' character, then an
environment variable name is expected to follow.

~/some/path ==> <my-home-dir>/some/path

~fred/some/path ==> <fred-home-dir>/some/path

$workdir/some/path ==> <workdir-env-var>/some/path

--modversion
Validate the file, write the [sub]module name, version and source filespec, then
exit.

--objview=string
Determines how objects are generated in HTML and YANG outputs. The default mode is
the raw view. XSD output is always cooked, since refined groupings and locally-
scoped definitions are not supported in XSD. Values:

raw -- output includes augment and uses clauses, not the
expanded results of those clauses.

cooked -- output does not include augment or uses clauses,
just the objects generated from those clauses.

--output=filespec
Output file name to use. Default is STDOUT if none specified and the defname
parameter is also missing.

If this parameter represents an existing directory, then the defnames parameter
will be assumed by default, and the translation output file(s) will be generated in
the specified directory.

If this parameter represents a file name, then the defnames parameter will be
ignored, and all translation output will be directed to the specified file.

~/some/path ==> <my-home-dir>/some/path

~fred/some/path ==> <fred-home-dir>/some/path

$workdir/some/path ==> <workdir-env-var>/some/path

--show-errors
If present, list each error or warning number and its default message string. The
program will exit after this is done.

--simurls=boolean
If true, and if HTML translation is requested, then this parameter will cause the
format of URLs within links to be generated in simplified form, for WEB development
engines such as CherryPy, which support this format. The default is false.

Normal URL format:
example.html?parm1=foo&parm2=bar#frag

Simplified URL format:
example/foo/bar#frag

--stats=enumeration
Controls YANG usage statistics report generation.
enum values:
none: (default)
No statistics reporting will be done.
brief:
Brief statistics reporting will be done:
- Complexity score
- Total nodes
basic:
Basic statistics reporting will be done.
advanced:
Advanced statistics reporting will be done.
all:
All possible statistics reporting will be done.

--subdirs=boolean
If false, the file search paths for modules, scripts, and data files will not
include sub-directories if they exist in the specified path.

If true, then these file search paths will include sub-directories, if present.
Any directory name beginning with a dot (.) character, or named CVS, will be
ignored. This is the default mode.

--subtree=string
Path specification of the directory subtree to convert. All of the YANG and YIN
source modules contained in the specified directory sub-tree will be processed.

If the format parameter is present, then one file with the default name will be
generated for each YANG or YIN file found in the sub-tree.

Note that symbolic links are not followed during the directory traversal. Only
real directories will be searched and regular files will be checked as modules.
Processing will continue to the next file if a module contains errors.

This parameter may be present zero or more times.

~/some/path ==> <my-home-dir>/some/path

~fred/some/path ==> <fred-home-dir>/some/path

$workdir/some/path ==> <workdir-env-var>/some/path

--totals=enumeration
Controls summary YANG usage statistics report generation. Must be used with the
'--stats' parameter.
enum values:
none: (default)
No summary statistics reporting will be done.
summary:
Summary statistics totals will be
reported, based on the stats mode
that is requested.
summary-only
Only the summary statistics totals
will be reported, based on the stats
mode that is requested. This mode
will cause all individual module
statistics reports to be generated,
and a summary for all input modules
will be generated instead.

--tree-identifiers
Validate the file, write the hierarchy of node names in tree format, that this
[sub]module contains, then exit.

--unified=boolean
If true, then submodules will be processed within the main module, in a unified
report, instead of separately, one report for each file.

For translation purposes, this parameter will cause any sub-modules to be treated
as if they were defined in the main module. Actual definitions will be generated
instead of an 'include' directive, for each submodule.

If false (the default), then a separate output file is generated for each input
file, so that XSD output and other reports for a main module will not include
information for submodules.

If this parameter is set to true, then submodules entered with the module parameter
will be ignored.

--urlstart=string
If present, then this string will be used to prepend to HREF links and URLs
generated for SQL and HTML translation. It is expected to be a URL ending with a
directory path. The trailing separator '/' will be added if it is missing.

If not present (the default), then relative URLs, starting with the file name will
be generated instead.

For example, if this parameter is set to

'http://acme.com/public'

then the URL generated for the 'bar' type on line 53, in the module FOO (version
2008-01-01) would be:

if no-versionnames set:

'http://acme.com/public/FOO.html#bar.53'

if no-versionnames not set (default):

'http://acme.com/public/FOO_2008-01-01.html#bar.53'

--version
Print yangdump version string and exit.

--versionnames=boolean
If false, the default filenames will not contain the module version string. If
true, the [sub]module name and version string are both used to generate a default
file name, when the defnames output parameter is used. This flag will cause
filenames and links to be generated which do not contain the version string. The
default value is true.

--warn-idlen=number
Control whether identifier length warnings will be generated. The value zero
disables all identifier length checking. If non-zero, then a warning will be
generated if an identifier is defined which has a length is greater than this
amount. range: 0 | 8 .. 1023. The default value is 64.

--warn-linelen=number
Control whether line length warnings will be generated. The value zero disables
all line length checking. If non-zero, then a warning will be generated if the
line length is greater than this amount. Tab characters are counted as 8 spaces.
range: 0 | 40 .. 4095. The default value is 72.

--warn-off=number
Control whether the specified warning number will be generated and counted in the
warning total for the module being parsed. range: 400 .. 899. This parameter may
be entered zero or more times.

--xsd-schemaloc=string
If present, then this string will be used to prepend to output XSD filenames, when
generating schemaLocation clauses. It is expected to be a URL ending with a
directory path. The trailing separator '/' will be added if it is missing. This
parameter is also prepended to URLs generated fpr include and import directives
within the XSD.

If not present (the default), then the schemaLocation element is not generated
during XSD translation. Relative URLs for include and import directives will be
generated, starting with the file name.

For example, if this parameter is set to

'http://acme.com/public'

then the schemaLocation XSD for the module FOO (version 01-01-2008) would be:

if no-versionnames set:

'http://acme.com/public/FOO.xsd'

if no-versionnames not set (default):

'http://acme.com/public/FOO_2008-01-01.xsd'

--yuma-home=string
Directory for the yuma project root to use. If present, this directory location
will override the YUMA_HOME environment variable, if it is present. If a zero-
length string is entered, then the YUMA_HOME environment variable will be ignored.

INPUT FILES

       Operations  can  be performed on one or more files with the module parameter, or an entire
       directory tree with the subtree parameter.   Unless  the  help,  version,  or  show-errors
       parameters  is  entered,  one  of these input file parameters is mandatory.  Each of these
       parameters may be entered multiple times.  The default parameter for yangdump is 'module',
       so these commands are wquivalent:

          yangdump --module=foo

          yangdump foo

       Note  that  'foo' must not match another parameter name.  If it does, the module parameter
       name must be used for that module.  For example,

          yangdump --module=help

SEARCH PATH

       When a module name is entered as input, or when a module or submodule name is specified in
       an  import or include statement within the file, the following search algorithm is used to
       find the file:

         1) file is in the current directory
         2) YUMA_MODPATH environment var (or set by modpath parameter)
         3) $HOME/modules directory
         4) $YUMA_HOME/modules directory
         5) $YUMA_INSTALL/modules directory OR
            default install module location, '/usr/share/yuma/modules'

       By default, the entire directory tree for all locations (except step 1) will be  searched,
       not  just  the  specified  directory.   The  subdirs parameter can be used to prevent sub-
       directories from being searched.

       Any directory name beginning with a  dot  character  (.)   will  be  skipped.   Also,  any
       directory named CVS will be skipped in directory searches.

OUTPUT MODES

       By default, any translation output will be sent to STDOUT.

       The  output  parameter  can be used to specify the full filespec of the output file to use
       instead.

       The defname parameter can be used to generate a default filename in the current  directory
       for the output.

          E.g., the default XSD filename is <name>_<version>.xsd.

       This is the default mode when subtree input mode is selected.

ERROR LOGGING

       By default, warnings and errors are sent to STDOUT.

       A log file can be specified instead with the log' parameter.

       Existing  log  files can be reused with the 'logappend' parameter, otherwise log files are
       overwritten.

       The logging level can be controlled with the log-level parameter.

       The default log level is 'info'.  The log-levels are additive:

            off:    suppress all errors (not recommended!)
                    A program return code of '1' indicates some error.
            error:  print errors
            warn:   print warnings
            info:   print generally interesting trace info
            debug:  print general debugging trace info
            debug2: print verbose debugging trace info
            debug3: print very verbose debugging trace info
            debug4: print maximum debugging trace info

ENVIRONMENT

       The following optional  environment  variables  can  be  used  to  control  module  search
       behavior:

       HOME   The user's home directory  (e.g., /home/andy)

       YUMA_HOME
              The root of the user's Yuma work directory (e.g., /home/andy/swdev/netconf)

       YUMA_INSTALL
              The  root  of  the directory that yangdump is installed on this system (default is,
              /usr/share/yuma)

       YUMA_MODPATH
              Colon-separated list of directories to search for modules and submodules.

              (e.g.: './workdir/modules:/home/andy/test-modules')

              The modpath parameter will override this environment variable, if both are present.

CONFIGURATION FILES

       yangdump.conf
              YANG config file The default is: /etc/yuma/yangdump.conf

              An ASCII configuration file format is supported to store command line parameters.

              The config parameter is used to specify  a  specific  config  file,  otherwise  the
              default config file will be checked.

                 - A hash mark until EOLN is treated as a comment
                 - All text is case-sensitive
                 - Whitespace within a line is not significant
                 - Whitespace to end a line is significant/
                   Unless the line starts a multi-line string,
                   an escaped EOLN (backslash EOLN) is needed
                   to enter a leaf on multiple lines.
                 - For parameters that define lists, the key components
                   are listed just after the parameter name, without
                   any name,  e.g.,

                          interface eth0 {
                            # name = eth0 is not listed inside the braces
                            ifMtu 1500
                            ifName mySystem
                          }

              A config file can contain any number of parameter sets for different programs.

              Each program must have its own section, identifies by its name:

                   # this is a comment
                   yangdump {
                      log-level debug
                      output "~/swdev/testfiles"
                   }

                   netconfd {
                      ...
                   }

FILES

       The  following  data  files  must  be  present in the module search path in order for this
       program to function:

         * YANG module library
           default: /usr/share/yuma/modules/

DIAGNOSTICS

       Internal diagnostics may generate the following type of message if any bugs  are  detected
       at runtime:

           [E0]
                filename.c:linenum error-number (error-msg)
