wish help you to fix your issue [d] matches nothing but the literal letter d. You want \d, without the brackets, to match a digit. However, it looks like you also want to include underscores. That would be [\d_].
Try this:
code :
/^MSM8_BD_V4\.3_[\d_]*-?([^-]+)/
1_idle
6_mp3
Camera_snap
Camera_snap
Radio_202.16

Perl regular expression to match perl regular expression literals

Perl regular expression to match perl regular expression literals

To fix the issue you can do Those operators can contain arbitrary Perl code, and there's no specification for that.
For example, in
code :
/$x{ EXPR }/
s// EXPR /e
balanced_paren_guts  : ( /(?:[^\\\(\)]|\\.)+/ | '(' balanced_paren_guts  ')' )(s?)
balanced_square_guts : ( /(?:[^\\\[\]]|\\.)+/ | '[' balanced_square_guts ']' )(s?)
balanced_curly_guts  : ( /(?:[^\\\{\}]|\\.)+/ | '{' balanced_curly_guts  '}' )(s?)


match_op        : <skip:> 'm' /\s*/ match_op_1 match_modifiers

match_op_1      : '(' <commit> balanced_paren  ')'
                | '[' <commit> balanced_square ']'
                | '{' <commit> balanced_curly  '}'
                | /(?x: ([^\\]) (?:(?!\1).|\\.)* \1 )/

match_modifiers : /\w+/


subst_op        : <skip:> 's' /\s*/ subst_op_1 subst_modifiers

subst_op_1      : '(' <commit> balanced_paren  ')' \s* subst_op_2
                | '[' <commit> balanced_square ']' \s* subst_op_2
                | '{' <commit> balanced_curly  '}' \s* subst_op_2
                | /(?x: ([^\\]) (?:(?!\1).|\\.)* \1 (?:(?!\1).|\\.)* \1 )/

subst_op_2      : '(' <commit> balanced_paren  ')'
                | '[' <commit> balanced_square ']'
                | '{' <commit> balanced_curly  '}'
                | /(?x: ([^\\]) (?:(?!\1).|\\.)* \1 )/

subst_modifiers : /\w+/

may help you . For the particular regex you want to convert, the equivalent in ECMA regex is:
code :
/^(\d{3,4})[- ]?(\d{4})[- ]?(\d{4})[- ]?(\d{4})$/

wish helps you Perl understand POSIX character classes in double brackets. So [^@[[:space:]]] is equivalent to [^@\s] (as long as [[:space:]] is the same as \s which I am not quite sure).
Can you re-write the Perl regexp with POSIX character classes? Then it would be easier to go from one to the other.
