1st Alternative(?sm)\/\*[^*]*\*+([^\/*][^*]*\*+)*\/(*SKIP)(*F)

(?sm)applies the following effective flags to the remainder of the pattern: gsm

s modifier: single line. Allows a dot to match line terminators

m modifier: multiline. Causes ^ and $ to match the start and end of each line, not only the start and end of the string

\/the literal / (47₁₀ / 57₈ / 2F₁₆)

\*the literal * (42₁₀ / 52₈ / 2A₁₆)

Negated Character Class[^*]*

*matches any number of characters outside the set below:

*the literal * (42₁₀ / 52₈ / 2A₁₆)

\*+the literal * (42₁₀ / 52₈ / 2A₁₆) , repeated at least once

Group 1([^\/*][^*]*\*+)*

*repeats the group contents below any number of times:

Negated Character Class[^\/*]

\/the literal / (47₁₀ / 57₈ / 2F₁₆)

*the literal * (42₁₀ / 52₈ / 2A₁₆)

Negated Character Class[^*]*

*matches any number of characters outside the set below:

*the literal * (42₁₀ / 52₈ / 2A₁₆)

\*+the literal * (42₁₀ / 52₈ / 2A₁₆) , repeated at least once

\/the literal / (47₁₀ / 57₈ / 2F₁₆)

(*SKIP)acts like (*PRUNE), but the next unanchored match attempt starts where (*SKIP) was reached instead of at the next subject character

(*F)forces the current match attempt to fail at this position

2nd Alternative^\s*([^=\n]+?)\s*=\s*(.*?);\h*(?:$|\r?\n)

^start of line

\s*any whitespace character, repeated any number of times

Group 2([^=\n]+?)

Negated Character Class[^=\n]+?

+?matches at least one character outside the set below:

=the literal = (61₁₀ / 75₈ / 3D₁₆)

\na line-feed (newline) character (ASCII 10)

\s*any whitespace character, repeated any number of times

=the literal = (61₁₀ / 75₈ / 3D₁₆)

\s*any whitespace character, repeated any number of times

Group 3(.*?)

.*?any character, repeated any number of times

;the literal ; (59₁₀ / 73₈ / 3B₁₆)

\h*any horizontal whitespace character, repeated any number of times

Non-Capturing Group(?:$|\r?\n)

1st Alternative$

$end of line

2nd Alternative\r?\n

\r?optionally matches a carriage return (ASCII 13)

\na line-feed (newline) character (ASCII 10)
