random function is very flexible, there are many custom functions can be created.
There are examples how to create custom function for most common cases:
Randex.fileName
Randex.random([
["english", "number"],
[3, 10],
]) +
"." +
Randex.random([
["english", "l"],
[2, 5],
]);
Randex.username
Randex.random(
["english", "l"],
[
[["english", "l"], "number"],
[5, 10],
]
);
Randex.email
Randex.random([
[["english", "l"], "number"],
[6, 10],
]) +
"@" +
Randex.random([
["english", "l"],
[2, 4],
]) +
"." +
Randex.random([
["english", "l"],
[1, 6],
]);
Randex.singleName
Randex.random(
["english", "u"],
[
["english", "l"],
[1, 10],
]
);
Randex.fullName
Randex.random(
["english", "u"],
[
["english", "l"],
[1, 10],
]
) +
" " +
Randex.random(
["english", "u"],
[
["english", "l"],
[1, 10],
]
);
Possible types:
number
: strict length
[number, number]
: an array of min and max length.
Example:
Randex.random({ set: "bit", length: 5 });
Randex.random({ set: "bit", length: [5, 10] });
// or short:
Randex.random(["bit", 5]);
Randex.random(["bit", [5, 10]]);
Possible types:
string
: an alphabet - RandexAlphabet or a set of chars - RandexKit
[string, string]
: the first item is - RandexAlphabet, the second item is - RandexCase
Example:
Randex.random({ set: "bit" });
Randex.random({ set: "spanish" });
Randex.random({ set: ["spanish", "lower"] });
// or short:
Randex.random("bit");
Randex.random("spanish");
Randex.random(["spanish", "l"]);
