zendata is a generic data generator. You can use YAML file to define the data format and use zendata to create it.

Parameters

  -d  --default    The default config file for data format.
  -c  --config     The current config file for data format, and it can override the config in the default file.
  -o  --output     The file name of the data generated. You can specify the output format by the extension name.
                   For example json, xml and sql.  The text data in the original format is output by default.
  -n  --lines      The number of lines of data to be generated. The default is 10.

  -F  --field      This parameter can be used to specify the fields, separated by commas. The default is all fields.
  -t  --table      If the output format is sql, using it to specify the table name to insert data to.
  -T  --trim       Remove the prefix and postfix of every field when outputting data.
  -H  --human      Output a readable format, print the field name, and use the tab key to split.

  -r  --recursive  Recursive mode. The default mode is parallel, in which each field loops independently.
                   The value of a field in the recursive mode depends on that of the previous field, which enables the random data.

  -p  --port       Run the HTTP on the specified port. The data in JSON format can be obtained via http://ip/ port. 
                   Only data generation is supported.
  -b  --bind       Listen IP addresses. All IP addresses are listened by default.
  -R  --root       The root directory when running HTTP. The client can call the config file under the root directory.
                   If not specified, take the directory where the zd executable file is located.

  -i  --input      Specify a sql schema file and output the YAML config file for each table. 
                   You need to specify an output directory by using -o.
  -D  --decode     Referring to the specified configuration file, parse the data file specified by -i and output json.
                   Also you can output the readable format via -H.

  -l  --list       List all supported data formats.
  -v  --view       View the detailed definition of a data format.
  -h  --help       Print help.
  -e  --example    Print the data format config file of the example.
