recheck

WARNING: β quality code

recheck is a program for validating regular expressions in go programs.

Why?

Currently validity of regular expressions is checked at run time, either by examining returned error of regexp.Compile or having regexp.MustCompile panic (usually in init).

recheck allows you to check your regular expressions at test/lint time. receck examines called to regexp.*Compile* and if the regular expression is a literal string - will check that it's valid.

recheck will also examine lines that have a comment in the following format:

r.HandleFunc("/articles/{category}/{id:[0-9]+}", handler) // recheck:0

Then number after "recheck:" is the argument to check (first one in this case)
