6.5 CQP macro examples

• use macros for easier access to embedded noun phrases (NP)

• write and load the macro definition file shown in Figure 6

  Figure 6: Macro definition file for accessing embedded noun phrases.

  

• then use /np_start[] and /np_end[] instead of <np> and </np> tags in CQP queries, as well as /np[] instead of /region[np]

  > /np_start[] /np[] "and" /np[] /np_end[];

• CQP ensures that the “generalised” start and end tags nest properly
  (if the StrictRegions option is enabled, cf. Sections 4.2 and 4.3)

• extending built-in macros: view definitions

  > show macro region(1);
> show macro codist(3);

• extend /region[] macro to embedded regions:

  MACRO anyregion($0=Tag) 
    (<$0>|<$01>|<$02>) 
    []*
    (</$02>|</$01>|</$0>)
  ;
  

• extend /codist[] macro to two constraints:

  MACRO codist($0=Att1 $1=V1 $2=Att2 $3=V2 $4=Att3) 
    _Results = [($0 = "$1") & ($2 = "$3")]; 
    group _Results match $4; 
    discard _Results;
  ;
  

• usage examples:

  > "man" /anyregion[pp];
> /codist[lemma, "go", pos, "V.*", word];

• the simple string interpolation of macros allows some neat tricks,
  e.g. a region macro with constraints on key-value pairs in the start tag

  MACRO region($0=Att $1=Key $2=Val)
    <$0_$1 = "$2"> []* </$0_$1>
  ;
  
  MACRO region($0=Att $1=Key1 $2=Val1 $3=Key2 $4=Val2)
    <$0_$1 = "$2"><$0_$3 = "$4"> []* </$0_$3></$0_$1>
  ;
