i want to wr

Answer 1

Start thinking about the structure of a definition, say,

(a line can start with some spaces) followed by,

(Type) followed by

(at least one space)
(variable_1)
(optionally
   (comma // next var
    |
    '='number // initialization
    ) ...`

then try to convert each group:

^      \s*    \w+           \s+        \w+         ?          (','    |  '=' \d+   ) ...
line  some    type          at least  var          optionally   more  or init some
start spaces  (some chars)  one space (some chars)              vars     val  digits

Left as homework to remove spaces and fix up the final regex.
