Regex to match valid Java path identifier -

suppose *a* java identifier. regex match things this:

\#a \#a.a.a (a number of times)

but not this:

\#a. (ending dot)

so in phase this: "#a.a less #a." match first \#a.a (because doesn't end dot).

this regex:

\#[a-za-z_$][\\w$]*(\\.[a-za-z_$][\\w$]*)*

almost job, matches last case too.

thank you.

you got right minor adjustments needed. consider regex:

#[a-za-z_$][\w$]*(?:\.[a-za-z_$][\w$]*)*(?!\w*\.)

translated java:

(?i)#[a-z_$][\\w$]*(?:\\.[a-z_$][\\w$]*)*(?!\\w*\\.)
