How do I convert square brackets to curly bracket in text using by regular expression?-CodePudding

How do I convert square brackets to curly brackets in text using regular expression?

I'm trying to convert
[[0,0,0,0,0],[0,0,1,0,3],[0,2,5,0,1],[4,2,4,4,2],[3,5,1,3,1]]
this to
{{0,0,0,0,0},{0,0,1,0,3},{0,2,5,0,1},{4,2,4,4,2},{3,5,1,3,1}}

Can I do it in a simple way? I found this Link but it's PHP way.

I'm trying this on an IDE like IntelliJ or online regex tester like regex101.

Thanks.

CodePudding user response：

In regex101 you can use the PCRE2 Replacement String Conditional trick.

Pattern :

(\[)|(\])

Basically capture the brackets in seperate capture groups.

Substitute :

${1: \{:$1}${2: \}:$2}

Or the golfcoded version

${1: \{:${2: \}}}

If group 1 not empty then replace with {.
If group 2 not empty then replace with }.

Test on regex101 here
