Visual Studio Code :Replace a text by another using regular expression

Suppose in your Visual Studio Code, you come at situtaion where you want to

replace certain text by other but simple Find & Replace isn't

a viable option then you can use regular expression.

e.g.If we want to replace {intermediateResult} with {float(intermediateResult)}.

In visual studio code launch Find & replace,then enable regular expression (the .* icon in the Find bar)

In Find:

            \{(intermediateResult)\}

In Replace TextBox:

            {float($1)}

Explanation:

    \{ and \} match literal curly braces (escaped with backslashes).

    (intermediateResult) captures the variable name.

    $1 in the replace refers to the captured group (i.e., intermediateResult).

In general if You want to replace {abcd} to {float(abcd)} then

Again Enable "Use Regular Expression" (.* icon)

In Find TextBox:

    \{([a-zA-Z_][a-zA-Z0-9_]*)\}

Replace:

    {float($1)}

Explanation:

    \{ and \} match literal curly braces.

    ([a-zA-Z_][a-zA-Z0-9_]*) matches any valid Python identifier:

    Starts with a letter or underscore

    Followed by letters, numbers, or underscores

    $1 refers to the captured variable name.
