Help needed in parsing file!!!!!

Messi

Hi,

    I am trying to parse a rule file and make into a table.My input file was like:

          ;RULE NO.  LAYER      TYPE       VALUE
               R1A,      POLY,      WIDTH,      0.6
               R1B,      POLY,      SPACE,      0.75
               R2A,      ACTIVE,    WIDTH,      1.5
               R2B,      ACTIVE,    SPACE,      0.75

 I was sucessful in parsing this and making into table using the following code:

               procedure( parseFile( ipFile )
                    let( ( index Table rulesFile value key line ruleLookup)
                      unless( ruleFile = infile( ipFile)
                      error( "Cannot open file %L for reading" ipFile)
                       ) ; unless
  
  
                Table = makeTable("myTable" nil)
                   rulesFile = infile( ipFile )
                  while( gets( line rulesFile )
                  index = parseString( line ",")
                  when(index
                   value = nil
          ;;Remove Headers of the rules file
                       unless(rexMatchp("RULE NO" car(index))
                        rexCompile("^ *")
                       key = rexReplace(car(index) "" 0)
                        foreach(col cdr(index)
                          col = buildString(parseString(col))
                           value = append1(value col))
                          when(key && value
                           Table[key] = value))
                           )
                          ) ;while file
                         close( rulesFile )
   
                   ;;Return values and arrange table
                  foreach(key sort(Table~>? 'alphalessp)
                      printf("%s:  " key)
                        foreach(col Table[key]
                        printf("%-15s " col))
                       printf("\n")
                         )
                      Table
                      ) ;let
                ) ;procedure

But if i modify my input file as:

             ;RULE NO.     LAYER/LAYERS      PURPOSE  MIN.VALUE    COMMENTS
                 R1A,          POLY,                     WIDTH,          0.5
                 R1B,          POLY/ACTIVE,      SPACING,         0.25        ;spacing btn POLY and ACTIVE
                 R1C,          POLY:PIN,                WIDTH,          0.5         ;                "
                 R2A,          ACTIVE,                    WIDTH,          0.5         ; 
                 R2B,          ACTIVE,                 SPACING,         0.25
                 R3A,          MET1:PIN,                 WIDTH,          0.5
                 R3B,          MET1/POLY,           SPACING,         0.3

 What changes i need to make in my earlier code so that it checks the layers instead of a single layer and parse them and put in list?? ie in the Table the layers section should have both the layers specified in rulefile after parsing them(eg: (POLY ACTIVE) in layer section for R1B...

Also i want to know how to ignore the COMMENTS section present in the input file.If anyone in the forum find solution for it,please help me out....

Thanks,

Messi

  •  You could check the length of the list you get after parseString. If the list is length 3, you can assume the single layer rule. If the list is length 4, it is a two layer rule and the second layer is the cadr of the list.

  • Hi Ted,

       i think checking length wont work as: if i have two layers and after parsing also length would be same as single layer as layers section will be together

    ie: after parsing it would be "R1A"        "POLY"           "WIDTH"     "0.6"        length = 4

                                            "R1B"  "POLY/ACTIVE"    "SPACE"  "0.25"         length=4

    I think i am correct,if not please let me know...

    Thanks,

    Messi

  • Hi Messi,

    Actually u can manipulate the parseString function to space up the string as below:

    line = "R1A   POLY/ACTIVE    WIDTH     0.6"

    parseString(line "/") -> "R1B"   "POLY"    "ACTIVE"    "SPACE"  "0.25"         length=5

  • Hi,

      thanks as per expert help i have modified my code as:

     

              
    procedure( parseFile( ipFile )
      let( ( index Table rulesFile value key line ruleLookup)
       unless( ruleFile = infile( ipFile)
          error( "Cannot open file %L for reading" ipFile)
          ) ; unless
     
     
        Table = makeTable("DRC_Table" nil)
        rulesFile = infile( ipFile )
        while( gets( line rulesFile )
          index = parseString( line ",")
      ;; To process two layers:
         i         =   setof(x parseString(line "/" equal(length(x)  5)
         index  =  appendl(list(cadr(x) caddr(x)) line)
         ipin    =   setof(y parseString(line ":" equal(length(y)  5)
         index  =  append1(list(cadr(y) caddr(y)) line)   
          when(index
            value = nil
     ;;Remove Headers of the rules file
            unless(rexMatchp("RULE NO" car(index))
            rexCompile("^ *")
              key = rexReplace(car(index) "" 0)
              foreach(col cdr(index)
                  col = buildString(parseString(col))
                  value = append1(value col))
          
                   )
           when(key && value
                  Table[key] = value)
             )
          ) ;while file
        close( rulesFile )
        

     ;;Return values and arrange table
        foreach(key sort(Table~>? 'alphalessp)
            printf("%s:  " key)
            foreach(col Table[key]
                printf("%-15s " col))
                printf("\n")
              )
             Table
       ) ;let
    ) ;procedure

    But i am not able to get the output,modified part is shown in bold font.If anyone can debug the error please help.

     Thanks,

  • Hi,

      I also want to know if i could do rexMatchp simulateonusly for two cases.ie here want to try to match "/ and :" if it is possible please tell me how is possible? i meant syntax to do so!

    Thanks,

    Messi

  • Hi Messi,

    Use:

    "[:/]"

    As the pattern. If using IC6, you also have pcreMatchp which has a far more powerful pattern syntax (these are the Perl Compatible Regular Expression functions)

    Regards,

    Andrew

  • Hi Andrew,

      Thanks for that similarly can i parse string simulatenously

          index = parseString( line "/" or line ":")

    is this possible??

    Thanks,

    Messi

  • Hi,

     I solved the issues.ignore the posts. :-)

    Thanks,

      Messi
