Question

How would I do regex matching in Erlang?

All I know is this:
f(“AAPL” ++ Inputstring) -> true.

The lines that I need to match
“AAPL,07-May-2010 15:58,21.34,21.36,21.34,21.35,525064\n”

In Perl regex: ^AAPL,* (or something similar)

In Erlang?

Answer 1

Use the re module, e.g.:

...
String = "AAPL,07-May-2010 15:58,21.34,21.36,21.34,21.35,525064\n",
RegExp = "^AAPL,*",
case re:run(String, RegExp) of
  {match, Captured} -> ... ;
  nomatch -> ...
end,
...
