7.3.6 Examples of gnatfind Usage

• gnatfind -f xyz:main.adb Find declarations for all entities xyz referenced at least once in main.adb. The references are search in every library file in the search path.

  The directories will be printed as well (as the -f switch is set)

  The output will look like:

           directory/main.ads:106:14: xyz <= declaration
           directory/main.adb:24:10: xyz <= body
           directory/foo.ads:45:23: xyz <= declaration
  

  I.e., one of the entities xyz found in main.adb is declared at line 12 of main.ads (and its body is in main.adb), and another one is declared at line 45 of foo.ads

• gnatfind -fs xyz:main.adb This is the same command as the previous one, but gnatfind will display the content of the Ada source file lines.

  The output will look like:

           directory/main.ads:106:14: xyz <= declaration
              procedure xyz;
           directory/main.adb:24:10: xyz <= body
              procedure xyz is
           directory/foo.ads:45:23: xyz <= declaration
              xyz : Integer;
  

  This can make it easier to find exactly the location your are looking for.

• gnatfind -r "*x*":main.ads:123 foo.adb Find references to all entities containing an x that are referenced on line 123 of main.ads. The references will be searched only in main.ads and foo.adb.
• gnatfind main.ads:123 Find declarations and bodies for all entities that are referenced on line 123 of main.ads.

  This is the same as gnatfind "*":main.adb:123`

• gnatfind mydir/main.adb:123:45 Find the declaration for the entity referenced at column 45 in line 123 of file main.adb in directory mydir. Note that it is usual to omit the identifier name when the column is given, since the column position identifies a unique reference.

  The column has to be the beginning of the identifier, and should not point to any character in the middle of the identifier.
