NAME
gnatstub - Generate skeletons for Ada package bodies
SYNOPSIS
gnatstub [OPTION]... filename [directory]
DESCRIPTION
gnatstub is an Ada library unit body sample generator. It takes a source file containing the source of an
Ada library unit declaration and generates the sample body for this unit in another source file. Sample
body is a kind of "minimal", but compilable body for a given unit declaration.
gnatstub is an ASIS application developed on top of the ASIS implementation for GNAT. The important thing
to know about gnatstub is that to create a body, gnatstub first compiles the spec to create in your
current directory the tree output file (or, simply, a tree file). After creating a body, gnatstub deletes
this tree file (the tree file may be kept by setting the corresponding option). Therefore, if you have
some other ASIS-based tools built on top of ASIS-for-GNAT, working on the tree files located in your
current directory, be aware of possible changes in the set of tree files as a result of using gnatstub.
OPTIONS
-f Replace an existing body file (if any) with a body sample. If destination directory contains a
file which should be considered as the body for filename according to the GNAT file name
conventions, gnatstub treats this file as a body for filename, and it does not create a sample
body if '-f' option is not set;
-hs Put in body sample the comment header from the source of the library unit declaration contained in
filename ("comment header" is all the comments preceding the compilation unit).
-hg Put in body sample a sample comment header.
-Idir
-I- These options have just the same meaning as in calls to gnatgcc or gnatmake. They are used to
define the source search path in the call to gnatgcc issued by gnatstub to create the tree file.
Note, that to create a body, gnatstub needs a legal Ada unit, therefore if filename depends on
some unit located in another directory, '-I' should be used to provide the path to this unit.
-in (n is a decimal natural number) Sets the indentation level in a body sample to n, '-i0' means "no
indentation", the default indentation is 3;
-k Do not remove the tree file: as default, gnatstub removes from the current directory the tree file
created for filename after creating the body sampler. '-k' prevents deleting the tree file.
-ln (n is a decimal positive number) Sets maximum line length in a body sample to n, the default line
length is 78;
-q Quiet mode: gnatstub does not generate a confirmation when a body is successfully created or a
message when a body is not required for an argument unit.
-t Overwrite the existing tree file: if the current directory already contains the file which,
according to the GNAT file name rules should be considered as a tree file for filename, gnatstub
will refuse to create the tree file needed to create a body sampler, unless '-t' option is set.
-v Verbose mode: gnatstub generates version information.
