This program is faker by random-select and support multi locale. Now, support Japan only. So, if you want to support other locale, please pull request data of the locale. You can generate formatted dummy data as xxxx. When it is String, formatter is "xxxx". When it is not String, formatter is xxxx.

As CLI

usage

 fakes-gen [FLAGS] [OPTIONS] [option]...
 

[FLAGS] and [OPTIONS]

// help message from fakes-gen -h 
FLAGS:
    -b, --bnf         show Backus-Naur Form and detail format for options
    -f, --fullform    flag for generating as fullform such as body with header
    -h, --help        Print this message
    -u, --usable      show list of all usable options for faker
    -V, --version     Prints version information

OPTIONS:
    -c, --converter <converter>    converter for output [default: csv]  [possible values: csv, tsv, json]
    -l, --locale <locale>          3-char's country code. [default: jpn]  [possible values: jpn]
    -s, --size <size>              data size. If 1, generate as record. If over 1, generate as data_set. [default: 1]

usable format of [option]

Usable format is form such as Xxxx.Yyyy(zzz) or Xxxx.Yyyy(zzz#sub). Xxxx is Category. Usable Category is "With", " "Fixed", "Select", "Lorem", "Name", "Primitive", "Internet", "Company", "Address", "DateTime" and "FileSystem". Yyyy is Option for each Category. Usable Option is theirs and zzz is <column_name>. If you use header or fullform, fakes-gen use <column_name>.

TODO

• FakeOption's item is to convert to form Category(EachOption)
• can use as cli tool
• add Primitive.Utf8 to FakeOption
• can specify character-code when generate
• move helper's [not_]string_formatted to each Converter
