      <!--
          The Software Index does not parse 'preprocessor' statements, like a C/C++ compiler.
          It just removes lines with preprocessor defines, includes, conditions and so on.
          As a result a code may include unfolded preprocessor strings
          which are normally replaced/removed by a compiler.
          
          For example, the initial code
              line  1: #define MAXIMUM_NUMBER (100)
              line  2: #ifdef DEBUG
              line  3:     if (currentNumber < MAXIMUM_NUMBER) {
              line  4:         printf("New overflow detected: %d\n", currentNumber);
              line  5:         count++;
              line  6:     }
              line  7: #else
              line  8:     if (currentNumber < MAXIMUM_NUMBER) {
              line  9:         count++;
              line 10:     }
              line 11: #endif
          is converted to:
              line  1: 
              line  2: 
              line  3:     if (currentNumber < MAXIMUM_NUMBER) {
              line  4:         printf("New overflow detected: %d\n", currentNumber);
              line  5:         count++;
              line  6:     }
              line  7: 
              line  8:     if (currentNumber < MAXIMUM_NUMBER) {
              line  9:         count++;
              line 10:     }
              line 11: 
          In the last example, the final code is parsable.
          If all your preprocessor statements are in the similar style and does not
          corrupt the structure of block start/end delimeters as in the example above,
          you do not need to bother about preprocessor stuff.
          
          However, if the initial code includes lines like these:
              line  1: #define MAXIMUM_NUMBER (100)
              line  2:     if (currentNumber < MAXIMUM_NUMBER) {
              line  3: #ifdef DEBUG
              line  4:         printf("New overflow detected: %d\n", currentNumber);
              line  5:         count++;
              line  6:     }
              line  7: #else
              line  8:         count++;
              line  9:     }
              line 10: #endif
          it is not parsable, because brackets mismatch is detected after preprocessing
          (see lines 6 and 9 below):
              line  1: 
              line  2:     if (currentNumber < MAXIMUM_NUMBER) {
              line  3: 
              line  4:         printf("New overflow detected: %d\n", currentNumber);
              line  5:         count++;
              line  6:     }
              line  7: 
              line  8:         count++;
              line  9:     }
              line 10: 
          Thus, in order to use Software Index tool it is necessary to refactor places,
          like in the example above.
          
          The section 'swi:preprocessor' is useful in other cases.
          For example, if the initial code includes the following lines:
              line  1: #define DECLARE_HANDLER(handlerName)                  \
              line  2:     int handlerName(unsigned int stateId,             \
              line  3:                     unsigned int eventId,             \
              line  4:                     struct EVENT_DATA_TYPE eventData)
              line  5: 
              line  6: DECLARE_HANDLER(leftButtonClick);
              line  7: DECLARE_HANDLER(rightButtonClick);
              line  8: 
              line  9: DECLARE_HANDLER(leftButtonClick)
              line 10: {
              line 11:     /* This function is called when left mouse button is clicked */
              line 12:     ...
              line 13: }
              line 14: 
              line 15: DECLARE_HANDLER(rightButtonClick)
              line 16: {
              line 17:     /* This function is called when right mouse button is clicked */
              line 18:     ...
              line 19: }
              line 20: 
          Software Index tool detects function DECLARE_HANDLER twice. As a result, they will be named:
              'DECLARE_HANDLER' and 'DECLARE_HANDLER (2)' accordingly.
          
          The better solution is to preprocess these strings using the preprocessor feature.
          For this particular example, it is recommended to define the rule which replaces the string:
              lines  6,7,9,15: DECLARE_HANDLER(_xxx_)
          by
              lines  6,7,9,15: int _xxx_(unsigned int stateId, unsigned int eventId, struct EVENT_DATA_TYPE eventData)
          where
              _xxx_ is the actual function name.
          In other words, the 'swi:preprocessor' section should include the following XML tags:
              <swi:rule>
                <swi:filepattern>your_regexp_file_pattern</swi:filepattern>
                <swi:searchpattern>([^_a-zA-Z0-9])DECLARE_HANDLER\(([^_a-zA-Z0-9])\)</swi:searchpattern>
                <swi:replacepattern>${1}int ${2}(unsigned int stateId, unsigned int eventId, struct EVENT_DATA_TYPE eventData)</swi:replacepattern>
              </swi:rule>
          As a result, the functions will be detected with the correct names:
              'leftButtonClick' and 'rightButtonClick' accordingly.
          
          'swi:preprocessor' section is optional.

          Scaner tool is used for global searching and violation reporting.
          If the scaner finds something, it reports the message which is also configured
          and increases the exit code from the Software Index Tool.
          
          For example, if you codding style requires to open the block begging from the new line:
              line  1: 
              line  2:     if (currentNumber < MAXIMUM_NUMBER)

              line  6: 
          it is possible to check it by scaner defining the 'swi:searchpattern' in the following way:
              [\n][^{][{]
          This regular expression matches the code which is 'badly' formated:
              line  1:

              line  5: 
          
          More examples. If you codding style does not allow to have noname structures, enums or unions:
              line  1: 
              line  2:     typedef struct _NAME_HERE_IS_MANDATORY_
              line  3:     {

              line  5:     } my_type;
              line  6: 
          it is possible to check it by scaner defining the 'swi:searchpattern' in the following way:
              (\s+)((union)|(enum)|(struct))(\s*{)
          This regular expression matches the code which is 'wrongly' written:
              line  1: 
              line  2:     typedef struct // noname here
              line  3:     {

          And if the 'swi:messagepattern' equals to:
              Noname '$2' detected.
          the error report looks like this:

          gcc/g++ compilers in combination with gcov tool are able to report

          Software Index has a bridge to this information which is configured
          in the 'swi:indexer:gcov' section below.
          
          Note: the feature works only if 'gcov' is visible in PATH environment.
          
          The short summary about possible coverage metrics:
          
          * Function coverage
            Has each function in the program been executed?

          * Statement coverage
            Has each line of the source code been executed?
            If at least one statement is executed, 'Function coverage' metric
            is equal to 100% (i.e. a function is executed at least once)

          * Decision coverage
            Has each control structure (such as an if statement) evaluated both to true
            and false?

          * Condition coverage
            Has each boolean sub-expression evaluated both to true and false?
            More 'strict' metric than 'Decision coverage'.
          
          * Modified Condition/Decision Coverage (MC/DC)
            Has every condition in a decision taken on all possible outcomes at least
            once? Has each condition been shown to affect that decision outcome
            independently?

          * Path coverage
            Has every possible route through a given part of the code been executed?

          * Entry/exit coverage
            Has every possible call and return of the function been executed?

            The coverage statistic is avaialble in 'gcda' files.

            Every source file, if it is touched by gcov, has
            corresponding gcda file.
            
            For example, if the initial source file is 'file.c' and
            the compiled binary file is 'file.o', the
            corresponding 'gcda' file with coverage data is 'file.gcda'
            
            Two options below define how to map
            the initial source file to the file with coverage data.
            
            'swi:sourcefile' is a regular expression. It is applied to name of a file.
            This operation gives variables ${1}, ${2}, ... according
            to regexp hooks.
            'swi:gcdafile' constructs the corresponding 'gcda' file.
            
            The example below demostrates the case of mapping:
                 from 'file.c' to 'file.gcda'
                 from 'otehrfile.c' to 'otherfile.gcda'
                 and so on...
            
            If the 'gcda' file is not found, coverage statistic is not collected and not reported.
            
            The example below demonstrates the default mapping scheme if options are missed.

          In addition to the extra info, it helps to filter the output information.
          For example, it is possible to print limit overheads for added and
          modified functions only (missing analogues messages for untouched objects).
          
          As a result, Software Index tool can be deployed to the software development
          process without extra work and remakes in your old sources.
          You can always start to measure/control the characteristics of
          objectes (functions) which are affected by your recent updates only,
          improving the total quality step-by-step (version-by-version).
          See 'Example 1' in the next section for examples.

          If the object with the corresponding modification status
          has some notification (exceeded limit, for example),
          the error counter is increased.
          The final value of the error counter is returned

      STATISTIC-GROUP / STATISTIC-NAME / STATISTIC-TYPE
      (See sections 'swi:indexer:common' and 'swi:indexer:dup' above)
      
      'swi:limits' section is optional.
  -->
  <swi:limits>
    <!-- 
        For example, if it is required to have proper (not too short)
        comment header, it is necessary to limit the statistic:
            'swi:lines/swi:comment:header/swi:exact'
        It is demonstarted in the following section:
    -->
    <!-- STATISTIC-GROUP -->

      <!-- STATISTIC-NAME -->
      <swi:comment:header>
        <!-- STATISTIC-TYPE -->
        <swi:exact>
          <!--
              After that, actual limits should be defined for three levels:
                  info, notice, warning
                  
              The common rule is that options should be in order:
                  'swi:info' < 'swi:notice' < 'swi:warning'
                OR:
                  'swi:info' > 'swi:notice' > 'swi:warning'
                  
              Note: limits can be negative, in this case they do not have any sense.
              
              In the example below, no messages are printed for a function
              if comment header before includes 5 lines at least.
              If it is so, the 'regular' level is attached to this function.
              If comment has 3-4 lines, level 'info' is assigned.
              If comment has 1-2 lines, level 'notice' is assigned.
              If there are no comments at all (0 lines), level 'warning' is assigned.

              the limit is applied to this object.
              Otherwise, the object is missed and the level becomes 'undefined' for the object.
              
              For example, value '^MY_PROJECT/MY_MODULE$' requires to apply the limit
              to the module only, missing statistics for the project, files and functions.
              
              By default, statistics are validated for all objects.
          -->
          <swi:objectpattern>.*</swi:objectpattern>
          
          <!--
              If some object is evaluated in non-regular level (info/notice/warning)
              and you consider that it is too excessive to fix it
              (or just there are no needs/benefits to do it),
              it is possible to define the exception and suppress the notification
              in the 'swi:suppress' section below.
              
              The exception should be defined in combination with 'swi:level' option.
              If there is notification for the object:
                  MY_PROJECT/MY_MODULE/my_file.c/myFunction
              with 'notice' level, the 'swi:level' should be equal to 'notice'.
              Otherwise, the notification will be still printed.
              In other words, severity of the message and suppress level should be equal.
              
              Also, one rule can suppress several objects. An object is considered as
              suppressed if it is matched by regular expression in 'swi:pattern' option.
              
              For example, the regexp pattern
                  MY_PROJECT/MY_MODULE/my_file.c/.*
              suppresses all functions in my_file.c in scope of
              MY_MODULE module in MY_PROJECT project.
              
              However, it it NOT recommended to use multiple suppressing,
              due to possible missmatch in severity of messages:
              For example, if there are two functions:
                  MY_PROJECT/MY_MODULE/my_file.c/myFunction1
                  MY_PROJECT/MY_MODULE/my_file.c/myFunction2
              and one of them is reported by the message with 'notice' level
              but the second is evaluated in 'regular' level,
              the 'swi:pattern' rule:
                  MY_PROJECT/MY_MODULE/my_file.c/.*
              will always result in the unsuppressable message,
              either for the first or for the second function.
              
              It is better to suppress all objects by their full reference.
              For example (see the previous example for prehistory)
                  <swi:pattern swi:level="notice">^MY_PROJECT/MY_MODULE/my_file.c/myFunction1$</swi:pattern>
              Symbols '^' and '$' are special regexp modifiers. They require immidiate borders in the name.

            For example, it is required to have at least 30% of comments per every function.
            This is defined by the relation:
            
            'swi:lines/swi:comment/swi:exact' / 'swi:lines/swi:executable/swi:exact' * 100%.

              and further development, minimal probability of bad fixes,
              better and easier understanding of a logical part of SW.
