How to parse parameters from a string if they are split by a blank space

Question

I am working on a project and currently I'm stuck.

I'm trying to parse from a string that's in this format

<string> <integer> <integer> <integer> <string>

The string is given by the user, for example this is users input:

Foo Bar 15 0 0 The quick brown fox jumps over the lazy dog

How would I get something like this?

['Foo Bar', 15, 0, 0, "The quick brown fox jumps over the lazy dog"]

Note: Strings can include integers

Thanks.

Answer 1

Regex seems like a reasonable solution, but you can do it with one call to .split .

When you include a capturing group ( (...) ) in the regex that you pass to .split , the captured text is included in the result array. This means you can split the text around the numbers but also capture the numbers with a pattern like /\\s+(\\d+)\\s+(\\d+)\\s+(\\d+)\\s+/ .

For example:

 var input = "Foo Bar 15 0 0 The quick brown fox jumps over the lazy dog" var regex = /\\s+(\\d+)\\s+(\\d+)\\s+(\\d+)\\s+/; var result = input.split(regex); console.log(result);

Answer 2

I'd personally use RegEx. Is the format of the string always the same?

If so.... I'd match the integer values:

"Foo Bar 15 0 0 The quick brown fox jumps over the lazy dog".match(/(\\d+\\s)+/g)

Then I would split using the resulting match.

let numbers = "Foo Bar 15 0 0 The quick brown fox jumps over the lazy dog".match(/(\d+\s)+/g)
["15 0 0 "]
let words = "Foo Bar 15 0 0 The quick brown fox jumps over the lazy dog".split(numbers[0].trim())
(2) ["Foo Bar ", " The quick brown fox jumps over the lazy dog"]
