For compatibility with existing tests, a +// bare string is interpreted as a regular expression matcher. +// +// On the regular expressions used in death tests: +// +// On POSIX-compliant systems (*nix), we use the library, +// which uses the POSIX extended regex syntax. +// +// On other platforms (e.g. Windows or Mac), we only support a simple regex +// syntax implemented as part of Google Test. This limited +// implementation should be enough most of the time when writing +// death tests; though it lacks many features you can find in PCRE +// or POSIX extended regex syntax. 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.
