Question

I am trying to build a regular expression to replace unresolved velocity variables with the syntax required by other parameterized variable frameworks such as spring jdbc and hibernate.
Essentially, I want a replacement pattern to find and replace ${a} with :a, ${b} with :b, etc.

Answer 1

Using generic regex syntax since you didn’t specify a language:

/\$\{([^}]+)}/:\1/g
/\$\{(.+?)}/:\1/g  # same thing in this case
