Henry Spencer's Regexp Engine Revisited

, 2 Jul 2003
A small, Unicode-aware regular expression engine based on Henry Spencer's early work
// -*- C++ -*-

class CRegExpException
    CRegExpException(int nError);

    int GetError() const;
    CString GetErrorString() const;

    int m_nError;

class CRegExp
    CRegExp(LPCTSTR pszPattern);

    BOOL Exec(const CString& sMatch);
    BOOL IsMatched(int nSubExp = 0) const;
    int GetMatchStart(int nSubExp = 0) const;
    int GetMatchEnd(int nSubExp = 0) const;
    CString GetMatch(int nSubExp = 0) const;
	int GetNumberOfMatches() const;

    void ResetMatches();
    void ConvertError(int nErrorCode) const;
    typedef regexp *PREGEXP;
    PREGEXP m_preCompiled;
    CString m_sMatch;
    std::vector<regmatch> m_arMatches;

    // disable copying
    CRegExp(const CRegExp&);
    CRegExp& operator=(const CRegExp&);

About the Author

Web Developer
Canada Canada
I'm a senior software developer, working at Silanis Technology ( I've acquired quite a bit of experience (usually the hard way!) in Win32 and raw COM programming on the job. In my spare time, I like to monkey around with POSIX code.

I'm mostly interested in portable C++ libraries. I'm happiest when I develop portable C++ code--C++ being such a powerful language as long as one keeps clear of the rather nasty subtleties of the language.

I hope the articles I contribute will be of some help to someone. If even one person gains a few hours through use of that code, I'll be very happy.

When not coding, I like to listen to Anime and try to learn Japanese. It's not working too well so far, unfortunately. :{)
