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.
AUTHOR¶
gnatstub is free software. It was originally developed by Alexei Kuchumov
as a part of collaboration between Software Engineering Laboratory of the
Swiss Federal Institute of Technology in Lausanne, Switzerland, in cooperation
with the Scientific Research Computer Center of Moscow State University (SRCC
MSU), Russia. This work was supported by a grant from the Swiss National
Science Foundation, no 7SUPJ048247, funding a project entitled
"Development of ASIS for GNAT with industry quality".
Now
gnatstub is maintained by Ada Core Technologies, Inc
