Find string surrounded by specific character, replace the characters but keep the string intact

Question

I have several documents that contains variables which need need to be changed from this:

@CapitalPx@

To this:

${CapitalPx}

I found out about finding and replacing using regex, and came out with the following one:

\@([a-z0-9]+)\@

My ultimate goal is to replace what I found with something that would look like the following:

\$\{([a-z0-9])\}

but it just replaces what I found by this string without interpreting it.

I also tried to find a regex that would match word starting or finishing with '@', but it doesn't work at 100% (LibreOffice seems limited for this)

Does anyone have a suggestion?

Thank you in advance

Answer 1

I'd do:

• Find: @(\w+)@
• Replace: ${$1}

Check Regular expression.

Explanation:

@       : literally @
(       : start group 1
  \w+   : 1 or more word character
)       : end group 1
@       : literally @
