Replacements

Consider this code (Lua book, page 185):

t = { status='up', name='Server' }
s = "$name is $status, isn't it?"
print(string.gsub(s, "$(%w+)", t))

In standard Lua we get:

Server is up, isn't it?	2

In Luan we get:

$name is $status, isn't it?	0

Why?

There was a bug that I fixed in rev 88.  But you still need to use Java regex (which is uglier) like this:

t = { status='up', name='Server' }
s = "$name is $status, isn't it?"
print(string.gsub(s, "\\$(\\w+)", t))

It works fine. The java regex is not a problem. Closing thread.
