For example, we don't support -// union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and -// repetition count ("x{5,7}"), among others. -// -// Below is the syntax that we do support. We chose it to be a -// subset of both PCRE and POSIX extended regex, so it's easy to -// learn wherever you come from. In the following: 'A' denotes a -// literal character, period (.), or a single \\ escape sequence; -// 'x' and 'y' denote regular expressions; 'm' and 'n' are for -// natural numbers. -// -// c matches any literal character c -// \\d matches any decimal digit -// \\D matches any character that's not a decimal digit -// \\f matches \f -// \\n matches \n -// \\r matches \r -// \\s matches any ASCII whitespace, including \n -// \\S matches any character that's not a whitespace -// \\t matches \t -// \\v matches \v -// \\w matches any letter, _, or decimal digit -// \\W matches any character that \\w doesn't match -// \\c matches any literal character c, which must be a punctuation -// . matches any single character except \n -// A? matches 0 or 1 occurrences of A -// A* matches 0 or many occurrences of A -// A+ matches 1 or many occurrences of A -// ^ matches the beginning of a string (not that of each line) -// $ matches the end of a string (not that of each line) -// xy matches x followed by y -// -// If you accidentally use PCRE or POSIX extended regex features -// not implemented by us, you will get a run-time failure. In that -// case, please try to rewrite your regular expression within the -// above syntax. -// -// This implementation is *not* meant to be as highly tuned or robust -// as a compiled regex library, but should perform well enough for a -// death test, which already incurs significant overhead by launching -// a child process. -// -// Known caveats: -// -// A "threadsafe" style death test obtains the path to the test -// program from argv[0] and re-executes it in the sub-process. For -// simplicity, the current implementation doesn't search the PATH -// when launching the sub-process. This means that the user must -// invoke the test program via a path that contains at least one -// path separator (e.g. path/to/foo_test and -// /absolute/path/to/bar_test are fine, but foo_test is not).
