Running gnatname

The usual form of the gnatname command is

     $ gnatname [switches] [naming_patterns]
     

All of the arguments are optional.

When used with no arguments, gnatname will create a file gnat.adc in the current working directory, that contains configuration pragmas for all compilation units in the current directory. To find all compilation units, gnatname will use the GNAT compiler in syntax-check-only mode on all regular files. For those files that contain an Ada compilation unit, a pragma Source_File_Name will be generated.

One or several Naming Patterns may be given as arguments to gnatname. Each Naming Pattern is enclosed between double quotes. A Naming Pattern is a regular expression similar to the wildcard patterns used in file names by the Unix shells or the DOS prompt.

Examples of Naming Patterns are

        "*.[12].ada"
        "*.ad[sb]*"
        "body_*"    "spec_*"
     

For a more complete description of the syntax of Naming Patterns, see the second kind of regular expressions described in g-regexp.ads (the "Glob" regular expressions).

Specifying no Naming Pattern is equivalent to specifying the single Naming Pattern "*".
