NAME

7       yanglint - YANG lint tool
8

SYNOPSIS

10       yanglint
11       yanglint [OPTIONS] [-f { yang | yin | tree } ] FILE ...
12       yanglint [OPTIONS] [-f { xml | json } ] SCHEMA...  FILE...
13

DESCRIPTION

15       yanglint  is  a  command-line  tool  for validating and converting YANG
16       schemas and the YANG modeled data. For a simple use, it  validates  the
17       provided  file  and  if  the output format specified, it converts input
18       data into the output format. If  started  with  no  argument,  yanglint
19       opens  interactive  environment  where the user is allowed to work with
20       schemas and data in a more complex way.
21

OPTIONS

23       -h, --help
24              Outputs usage help and exits.
25
26       -v, --version
27              Outputs the version number and exits.
28
29       -V, --verbose
30              Increases the verbosity level. If not specified, only errors are
31              printed,  with  each  appearance it adds: warnings, verbose mes‐
32              sages, debug messages (if compiled with debug information).
33
34       -p PATH, --path=PATH
35              Specifies search path for getting imported modules  or  included
36              submodules.  The  option can be used multiple times. The current
37              working directory and path of the module  being  added  is  used
38              implicitly.
39
40       -s, --strict
41              Changes  handling  of  unknown  data nodes - instead of silently
42              ignoring unknown data, error is printed and data parsing  fails.
43              This option applies only on data parsing.
44
45       -f FORMAT, --format=FORMAT
46              Converts  the content of the input FILEs into the specified FOR‐
47              MAT. If no OUTFILE is specified, the data  are  printed  on  the
48              standard output. Only the compatible formats for the input FILEs
49              are allowed, see the section FORMATS.
50
51       -o OUTFILE, --output=OUTFILE
52              Writes the output data into the specified  OUTFILE.  The  option
53              can be used only in combination with --format option. In case of
54              converting schema, only a single input schema FILE  is  allowed.
55              In  case of data input FILEs, input is merged and printed into a
56              single OUTFILE.
57
58       -F FEATURES, --features=FEATURES
59              Specifies the list  of  enabled  features  in  the  format  MOD‐
60              ULE:[FEATURE,...].  In  case of processing multiple modules, the
61              option can be used repeatedly. To disable all the features,  use
62              an empty list specified for the particular module.
63
64       -d MODE, --default=MODE
65              Print  data with default values, according to the MODE (to print
66              attributes,  the  ietf-netconf-with-defaults   model   must   be
67              loaded). The MODE is one of the following:
68               · all             - add missing default nodes
69               ·  all-tagged      - add missing default nodes and mark all the
70              default nodes with the attribute
71               · trim            - remove all nodes with a default value
72               · implicit-tagged - add missing nodes and mark  them  with  the
73              attribute
74
75       -t TYPE, --type=TYPE
76              Specify  data tree type in the input data FILEs. The TYPE is one
77              of the following:
78               · auto            - Resolve data type (one  of  the  following)
79              automatically  (as  pyang  does).  Applicable  only on XML input
80              data.
81               ·  data             -  Complete  datastore  with  status   data
82              (default type).
83               ·  config           -  Configuration  datastore (without status
84              data).
85               · get             - Result of the NETCONF <get> operation.
86               · getconfig       - Result of the NETCONF  <get-config>  opera‐
87              tion.
88               · edit            - Content of the NETCONF <edit-config> opera‐
89              tion.
90               · rpc             -  Content  of  the  NETCONF  <rpc>  message,
91              defined as YANG's rpc input statement.
92               ·  rpcreply         -  Reply to the RPC. This is just a virtual
93              TYPE, for parsing replies, 'auto' must be used  since  the  data
94              FILEs are expected in pairs.
95                                   The  first  input  data FILE is expected as
96              'rpc' TYPE, the second FILE is expected as reply to the previous
97              RPC.
98               ·  notif            -  Notification  instance  (content  of the
99              <notification> element without <eventTime>.
100
101       -O FILE, --operational=FILE]
102              Optional parameter for 'rpc' and 'notif' TYPEs,  the  FILE  con‐
103              tains  running configuration datastore and state data referenced
104              from the RPC/Notification. The same data apply to all input data
105              FILEs.  Note  that the file is validated as 'data' TYPE. Special
106              value '!' can be used as FILE argument to  ignore  the  external
107              references.
108
109       -y YANGLIB_PATH
110              Specify  path to a yang-library data file (XML or JSON) describ‐
111              ing the initial context.  If provided, yanglint loads  the  mod‐
112              ules  according  to  the  content of the yang-library data tree.
113              Otherwise, an empty content with only the internal libyang  mod‐
114              ules  is  used. This does not limit user to load another modules
115              explicitly specified as command line parameters.
116

FORMATS

118       There are two types of formats to use.
119
120       Schemas
121              In case of schemas,  the  content  can  be  converted  into  the
122              'yang',  'yin'  and  'tree' formats. As input, only YANG and YIN
123              files are accepted. Note, that the corresponding file  extension
124              is required.
125
126       Data  In  case  of  YANG  modeled  data,  the  content can be converted
127       between 'xml'
128              and 'json' formats. Remember that the corresponding file  exten‐
129              sion of the input file is required.

EXAMPLES

133       · Open interactive environment:
134             yanglint
135
136       · Convert YANG model into YIN and print it to the stdout:
137             yanglint --format=yin ./ietf-system.yang
138
139       · Convert ietf-system configuration data from XML to JSON:
140             yanglint  --format=json  --type=config --output=data.json ./ietf-
141         system.yang ./data.xml
