    Methods

    The string to parse in the methods may be given as a null terminated string, in which case the length argument should be -1.

    Out parameters of the methods are all optional (that is the caller may pass-in a null value if the corresponding results are not needed). Signed out parameters may hold a value of -1 if the corresponding result is not part of the string being parsed.

    The parsing routines attempt to be as forgiving as possible.

    parseAuthority()

    Breaks the authority string up into its 4 components: username, password, hostname, and hostport.

    auth = <username>:<password>@<hostname>:<port>

    void parseAuthority(
      in string authority,
      in long authorityLen,
      out unsigned long usernamePos,
      out long usernameLen,
      out unsigned long passwordPos,
      out long passwordLen,
      out unsigned long hostnamePos,
      out long hostnameLen,
      out long port
    );
    
    Parameters
    authority
    authorityLen
    usernamePos
    usernameLen
    passwordPos
    passwordLen
    hostnamePos
    hostnameLen
    port

    parseFileName()

    filename = <basename>.<extension>

    void parseFileName(
      in string filename,
      in long filenameLen,
      out unsigned long basenamePos,
      out long basenameLen,
      out unsigned long extensionPos,
      out long extensionLen
    );
    
    Parameters
    filename
    filenameLen

    parseFilePath()

    Breaks the file path string up into: the directory portion, file base name, and file extension.

    filepath = <directory><basename>.<extension>

    void parseFilePath(
      in string filepath,
      in long filepathLen,
      out unsigned long directoryPos,
      out long directoryLen,
      out unsigned long basenamePos,
      out long basenameLen,
      out unsigned long extensionPos,

    filepathLen
    directoryPos
    directoryLen
    basenamePos
    basenameLen
    extensionPos
    extensionLen

    parsePath()

    Breaks the path string up into its 4 major components: a file path, a param string, a query string, and a reference string.

    path = <filepath>;<param>?<query>#<ref>

    void parsePath(
      in string path,
      in long pathLen,
      out unsigned long filepathPos,
      out long filepathLen,
      out unsigned long paramPos, // Removed in Gecko 9.0
      out long paramLen, // Removed in Gecko 9.0
      out unsigned long queryPos,
      out long queryLen,
      out unsigned long refPos,
      out long refLen
    );
    
    Parameters
    path
    pathLen
    filepathPos
    filepathLen
    paramPos Obsolete since Gecko 9.0
    paramLen Obsolete since Gecko 9.0
    queryPos
    queryLen
    refPos
    refLen

    parseServerInfo()

    serverinfo = <hostname>:<port>

    void parseServerInfo(
      in string serverinfo,
      in long serverinfoLen,
      out unsigned long hostnamePos,
      out long hostnameLen,
      out long port
    );
    
    Parameters
    serverinfo
    serverinfoLen
    hostnamePos
    hostnameLen

    parseURL()

    Breaks the URL string up into its 3 major components: a scheme, an authority section (hostname, and so on.), and a path.

    spec = <scheme>://<authority><path>

    void parseURL(

      in long specLen,
      out unsigned long schemePos,
      out long schemeLen,

    specLen
    schemePos
    schemeLen
    authorityPos
    authorityLen
    pathPos
    pathLen

    parseUserInfo()

    userinfo = <username>:<password>

    void parseUserInfo(
      in string userinfo,
      in long userinfoLen,
      out unsigned long usernamePos,
      out long usernameLen,
      out unsigned long passwordPos,
      out long passwordLen
    );
    
    Parameters
    userinfo
    userinfoLen
    usernamePos
    usernameLen
    passwordPos
    passwordLen

    Notes

    Starting in Gecko 9.0 (Firefox 9.0 / Thunderbird 9.0 / SeaMonkey 2.6), this no longer treats the semicolon as a "parameter string" marker. This was never a valid part of a URL, and is now no longer supported. This makes URLs with semicolons in them work correctly.
