The usual form of the
gnatname command is:
$ gnatname [ switches ] naming_pattern [ naming_patterns ] [--and [ switches ] naming_pattern [ naming_patterns ]]
All of the arguments are optional. If invoked without any argument,
gnatname will display its usage.
When used with at least one naming pattern,
gnatname will attempt to
find all the compilation units in files that follow at least one of the
naming patterns. To find these compilation units,
gnatname will use the GNAT compiler in syntax-check-only mode on all
One or several Naming Patterns may be given as arguments to
Each Naming Pattern is enclosed between double quotes (or single
quotes on Windows).
A Naming Pattern is a regular expression similar to the wildcard patterns
used in file names by the Unix shells or the DOS prompt.
gnatname may be called with several sections of directories/patterns.
Sections are separated by the switch
--and. In each section, there must be
at least one pattern. If no directory is specified in a section, the current
directory (or the project directory if
-P is used) is implied.
The options other that the directory switches and the patterns apply globally
even if they are in different sections.
Examples of Naming Patterns are:
"*..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
(the ’Glob’ regular expressions).
When invoked without the switch
gnatname will create a
configuration pragmas file
gnat.adc in the current working directory,
