How to parse an arguments containing a url from a string so that url doesn't split on query par-CodePudding

I'm building a desktop app and it accepts a number of flags through cli args.
Args Looks like this "configURI=launch://test.domain.com:7089/jav_config.ws,gameWorld=2,character=Test"
Previously I parsed it with regexp:
https://regex101.com/r/V8a2Kr/1

export const COMMA_DELIMITEDREGEXP = /\w =(?:[[a-zA-Z0-9 []:/.~,=-]]|[a-zA-Z0-9 _:/.~-])|\w /g; 
const args = "configURI=launch://test.domain.com:7089/jav_config.ws,gameWorld=2,character=Test"

args.match(COMMA_DELIMITEDREGEXP)

// Returns object with 3 entries
// 0: "configURI=launch://test.domain.com:7089/jav_config.ws"
// 1: "gameWorld=2"
// 2: "characther=Test"

But I found a bug with parsing URL string if it has any query params on it.

e.x. configURI=test.domain.com:7089/jav_config.ws?devbuild=1

const args = "configURI=launch://test.domain.com:7089/jav_config.ws?devbuild=1,gameWorld=2,character=Test"

args.match(COMMA_DELIMITEDREGEXP)

// Returns object with 4 entries
// 0: "configURI=launch://test.domain.com:7089/jav_config.ws"
// 1: "devbuild=1"
// 2: "gameWorld=2"
// 3: "characther=Test"

I want to not break URL string, hence parsing result should be

// 0: "configURI=launch://test.domain.com:7089/jav_config.ws?devbuild=1"
// 1: "gameWorld=2"
// 2: "characther=Test"

I could add another regexp only for the URL matching and use existing regexp to parse other entries.
But I wonder if there is any way to somehow modify existing regexp so it will not split URLs with query params into two entries?

CodePudding user response：

You can split the input string by any comma that is succeeded by a parameter name:

,(?=\w =)

const input = "configURI=launch://test.domain.com:7089/jav_config.ws?devbuild=1&characters=[Test, Test2],gameWorld=2,character=Test";

const regex = /,(?=\w =)/g;

const parts = input.split(regex);

console.log(parts);

Try it.

CodePudding user response：

Assuming there is no nested level and taking coma separated lists, if you can enforce these are enclosed in brackets, you may use something like this:

[^=,] =(?:\[[^\]] \]|[^,] )(?![^,])
