22.5 Converting Ada Files to html with
Perl script allows Ada source files to be browsed using
standard Web browsers. For installation procedure, see the section
See Installing gnathtml.
Ada reserved keywords are highlighted in a bold font and Ada comments in
a blue font. Unless your program was compiled with the gcc -gnatx
switch to suppress the generation of cross-referencing information, user
defined variables and types will appear in a different color; you will
be able to click on any identifier and go to its declaration.
The command line is as follow:
$ perl gnathtml.pl [switches] ada-files
You can pass it as many Ada files as you want.
gnathtml will generate
an html file for every ada file, and a global file called index.htm.
This file is an index of every identifier defined in the files.
The available switches are the following ones :
- Only the subset on the Ada 83 keywords will be highlighted, not the full
Ada 95 keywords set.
- This option allows you to change the color used for comments. The default
value is green. The color argument can be any name accepted by html.
- If the ada files depend on some other files (using for instance the
with command, the latter will also be converted to html.
Only the files in the user project will be converted to html, not the files
in the run-time library itself.
- This command is the same as -d above, but
gnathtml will also look
for files in the run-time library, and generate html files for them.
- By default, gnathtml will generate html links only for global entities
('with'ed units, global variables and types,...). If you specify the
-f on the command line, then links will be generated for local
- If this switch is provided and number is not 0, then
will number the html files every number line.
- Specify a directory to search for library files (.ali files) and
source files. You can provide several -I switches on the command line,
and the directories will be parsed in the order of the command line.
- Specify the output directory for html files. By default, gnathtml will
saved the generated html files in a subdirectory named html/.
- If you are using Emacs and the most recent Emacs Ada mode, which provides
a full Integrated Development Environment for compiling, checking,
running and debugging applications, you may be using .adp files
to give the directories where Emacs can find sources and object files.
Using this switch, you can tell gnathtml to use these files. This allows
you to get an html version of your application, even if it is spread
over multiple directories.
- This option allows you to change the color used for symbol definitions.
The default value is red. The color argument can be any name accepted by html.
- This switch provides the name of a file. This file contains a list of
file names to be converted, and the effect is exactly as though they had
appeared explicitly on the command line. This
is the recommended way to work around the command line length limit on some
