Writing a new module

-module(http).

that particular one wont screw up on the current otp release, but its fairly easy to write one that will if you dont use your own prefix, and it causes the hardest to diagnose errors around.

list_to_atom on increasing sequence numbers will make for a good crash...

Forgetting a comma between strings in a list, like ["foo" "bar"]

Made for a _very_ insidious and hard to find bug.

lists:seq(1:100).

Erlang answers with "illegal expression" -> an afternoon of code review :(
And I STILL continue to write this!!!

Here's a one-line AWK script you can use to check for this.

#!/bin/awk -f
/[^a-zA-Z0-9_][0-9]+ *:/ { print FILENAME ":" FNR ": integer-colon error" }

You can probably configure your editor to run this on a keystroke.

Of course 1:100 is perfectly legal S, so it's not _that_ silly a mistake.

If we only could get a public repository for Wrangler rules[1] we could have these checks actually integrated with proper Erlang tools

Wrangler can now be found here:
https://github.com/RefactoringTools/wrangler

It's now also much easier to compile and set up, and plays well with a
modern Distel (which is found at https://github.com/massemanet/distel,
if you want to get it separately, but Wrangler includes a recent version).

Richard - thanks for nudging us to doing this. The Wrangler team plans a release in the next few weeks with stable versions of the scripting, and a repository for scripts.

Simon and Huiqing
