I have a string like this

const str = "Today is going to be @[City Temp](city-temp) in @[City Name](city-name)"

I want the output to be in handlebars syntax eg

const str = "Today is going to be {{city-temp}} in {{city-name}}"

I am having trouble trying to match this pattern.

I can see that if I do

str.replace(/[()]/g,"")

I get the string without the brackets.

But I can't work out how to search for the whole pattern something like the below where I find anything starting with @[ and ending with ), I don't want to just start with @ by itself as there may be times in the string I don't want to remove the @ where it is not followed by a [

/[\@\[A-Za-z0-9\](A-Za-z0-9-)

CodePudding user response：

You can use

str = str.replace(/@\[[^\][]*]\(([^()]*)\)/g, "{{$1}}")

See the regex demo. Details:

• @\[ - a @[ string
• [^\][]* - zero or more chars other than [ and ]
• ]\( - a ]( string
• ([^()]*) - Group 1 ($1): any zero or more chars other than ( and )
• \) - a ) char.

See the JavaScript demo:

const str = "Today is going to be @[City Temp](city-temp) in @[City Name](city-name)"
console.log(str.replace(/@\[[^\][]*]\(([^()]*)\)/g, "{{$1}}"))
