"foo = '@test.bar';\nfooa = @test.darn;".match(/@([a-z][a-z\.-_]*)/igm)
Why does this match
["@test.bar", "@test.darn;"]
rather than just
["@test.bar", "@test.darn"]
?
In character classes, some letters have special meanings. The dot for example has none and does not need to be escaped. The minus in contrast defines a range of characters, and if you mean literally minus you need to escape it or put it in the end/beginning of the character class. Your range from
.to_actually includes./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_. You may want to use[a-z.\-_]or[a-z._-]instead.
