(Does *not* get into programming questions.) Sender: netnews@sei.cmu.edu (Netnews) Organization: Ada Information Clearinghouse Date: Thu, 25 Mar 1993 17:59:39 EST Date: 1993-03-25T17:59:39-05:00 List-Id: Archive-name: comp-lang-ada/cla-faq1 comp.lang.ada Frequently Asked Questions (FAQ) part 1 of 2 Effective date: 25 MAR 93 Currently, the comp.lang.ada FAQ is maintained by the Ada Information Clearinghouse (cla-faq@ajpo.sei.cmu.edu). It is available for downloading via anonymous FTP from the AJPO host (ajpo.sei.cmu.edu) from the public/comp-lang-ada subdirectory as files cla-faq1 and cla-faq2. Frequency: This will be posted every other month to comp.lang.ada, news.answers, and comp.answers. Changes since the last FAQ: Four questions added: two on POSIX/Ada binding, one on obtaining benchmarks, and one on FTP mail for downloading Ada files from ajpo.sei.cmu.edu; otherwise, no changes since last time. Individuals are encouraged to submit both questions and answers. In many answers below, submitters are noted in parentheses at the beginning of comments. (Comments may be slightly edited.) It should be noted that report of a product, service, or event, etc., does not constitute an endorsement by the AdaIC or the Ada Joint Program Office. Opinions expressed are those of the submitters.

But I don't have FTP service on the Internet host where I have an account. Is there any way I can get those files? 1) Where can I get a list of validated Ada compilers? (from tjmesler@vnet.ibm.com) By anonymous ftp from ajpo.sei.cmu.edu. The latest list is in the /public/ada-info directory. Only the latest list is kept; it has the name val-comp.hlp.ddmmmyy, where dd stands for date, mmm for month (3-letter abreviation), and yy stands for year. For example, the current list is val-comp.hlp.01Oct92. If the list is updated during the month, the previous one is deleted and the date part of the name of the file will change. 2) Where can I get a yacc/ayacc grammar to read Ada code? (from garym@flash.telesoft.com (Gary Morris @lone)) masticol@dumas.rutgers.edu has kindly sent in a yacc and lex grammar for Ada. It's available via FTP from the archives at primost.cs.wisc.edu and via e-mail from the compilers server at compilers-server@iecc.cambridge.ma.us. 3) Is there an Ada-mode for Emacs? (from boubaker@mailhost.cenatls.cena.dgac.fr (Heddy Boubaker)) There are, in fact, 3 ada modes for emacs - There is a simple ada-mode shipped as part of the emacs distribution. - a more elaborate one from Steven D. Litvintchouk of Mitre Corp called electric-ada - and gnu-ada mode. Here is a small description of the features of this mode: 1/ Compile programs within emacs Run compiler as inferior of Emacs, and parse its error messages. NOTE: I believe that this feature will only work with VADS, but it might have been tailored to work with other compilers. 2/ Ada dired It supplies a form of dired that helps manage the VADS environment, and it adds ADA vads commands into ada mode. Unlike a previous dired-ada implementation, this version uses the existing dired mode functions except where there is unresolvable conflict. Thus, this is more like a minor mode to dired. Very important because on actual version of emacs 19(beta), in fact lemacs (lucid emacs), dired has changed and we can no longer use gnu-ada mode :-( 3/ you can consult Ada LRM(*) during parsing error message. (*)You can get one in wsmr-simtel20.army.mil or any mirror site. 4/ smart indentation Tries hard to do all the indenting automatically. Emphasizes correct insertion of new code using smart templates. 5/ Smart template commands (bnf) This is essentially a bnf processor/language-sensitive editor. The next message will give you an ada bnf file that you can use within ada-mode to expand nonterminals. But you can roll your own grammars (e.g., your design grammar or an ADL) and put them in *.bnf files .. ; The BNF rule set is stored as a list of rules. 6/ debugging Ada programs within emacs A facility is provided for the simultaneous display of the source code in one window, while using a.db to step through a function in the other. A small arrow "=>" in the source window, indicates the current line. 7/ Move from procedure to procedure or package to package ... 8/ tags Ada 9/ and other things ... (from obry@enthuse.bellcore.com (Pascal OBRY)) You can find the gnu-ada mode in ajpo.sei.cmu.edu cd /public/infoada/gnu file r1.06a-ada.tar.Z 4) You know, I think Ada could really benefit from having from or You know, I think Ada is clearly to because it has (from drew@verdix.com (Drew Johnson)) Such posts almost always result in religious wars about langauge and produce only wasted bandwidth. PLEASE refrain from such posts unless you have a specific question about Ada. For example, the following kind of question *is* appropriate: "In I can do . How would I go about doing this in Ada?" 5) I just saw a very anti-Ada post that I think is definitely wrong. Why didn't anybody post a response to it? Should I? (from drew@verdix.com (Drew Johnson)) Ada apparently gets more than its share of attacks, probably due to its unique origins, and the fact that it is a requirement for some government software. For the same reasons as in (4) above, PLEASE refrain from posting a response to these, unless you feel there is something of *significant* importance that you can contribute. Posts containing factual corrections are probably OK, but posts like "Well, I've used Ada on many projects, and all have been very successful" accomplish nothing. If you are really dead-set on driving your point home to the poster, you can do it via e-mail. 6) Where can I get a public-domain Ada compiler? There is currently no public-domain Ada compiler available. However, a compiler for Ada 9X is in the works, and there is an interpreter for Ada 83. The interpreter is available from the New York University host (cd.nyu.edu, Internet address 128.122.140.24). Interpreter for Ada 83: (from mfeldman@cs.washington.edu (Michael Feldman)) While there is no PD 'compiler', Ada/Ed is available, which is an Ada interpreter. It is available for PCs, Unix-based machines, Amiga, and Atari systems. Excerpt from the Ada/Ed README: Ada/Ed is a translator-interpreter for Ada. It is intended as a teaching tool, and does not have the capacity, performance, or robustness of commercial Ada compilers. Ada/Ed was developed at New York University, as part of a long-range project in language definition and software prototyping. The project produced the first validated translator for Ada, in the form of an executable definition of the language written in SETL. The SETL system served as design document and prototype for the C version [available from the NYU host.] Ada/Ed was last validated under version 1.7 of the ACVC tests. Therefore it is not currently a validated Ada system, and users can expect to find small discrepancies between Ada/Ed and currently validated compilers. Apart from the 100-odd tests of ACVC 1.11 that Ada/Ed currently fails, the major deficiency of the system is that, being an interpreter, it does not implement most representation clauses, and thus does not support systems programming close to the machine level. Compiler for Ada 9X: GNU is officially working on a free Ada compiler. (from schonber@acf3.NYU.EDU (Ed Schonberg)) The Computer Science Department of the Courant Institute of Mathematical Sciences at New York University is pleased to announce that it has received a contract from the Ada/9X Project Office to develop a GNU/Ada system. The work is being cosponsored by DARPA and the Ada Joint Project Office, under the direction of Christine M. Anderson. The project involves the implementation of a highly efficient compiler system for the Ada language. The compiler is to be an integral part of the GCC system, distributed by the Free Software Foundation. Richard Stallman, head of the FSF, is cooperating closely with NYU to ensure that the new Ada component will fit smoothly into GCC. GNU/Ada will be distributed as a standard part of the GCC system. The project is under the direction of Professors Robert B. K. Dewar and Edmond Schonberg. The design team includes members of the NYUADA project as well as GCC designers. Bernard Banner, Franco Gasperoni, Brett Porter and Gail Schenker have participated in various aspects of the design and implementation of Ada/Ed. Richard Kenner has retargetted the GCC backend to several modern RISC architectures. Sam Figueroa, Laurent Bardet and several graduate students will participate in the design and implementation of selected modules of the run-time. Finally, Jean-Pierre Rosen, one of the original designers of Ada/Ed, will be acting as a consultant in the area of tasking. Collectively, this group represents over a hundred person-years of experience in Ada implementation and compiler technology. The project has an opening for one additional senior staff person. Substantial experience in compiler technology is required, as well as fluency in Ada. Those interested should send e-mail to dewar@cs.nyu.edu or schonberg@cs.nyu.edu. The main goal of the project, nicknamed GNAT (GNU NYU Ada Translator) is to provide a free implementation of Ada/9X, the new version of Ada currently being designed. As is well-known, the name Ada/9X reflects the fact that the completion date for its standardization is not yet known, although it is expected that X will be 3 or 4. GNAT will implement as much as possible of the Ada/9X design over the 18 month duration of the project; it is anticipated that all the important functionality of Ada/9X will be covered. The project does not include any commitment to formal validation, since neither the approved standard, nor the validation suite will be available in time. Instead, the objective is to provide to the Ada community, in the most timely fashion, a reasonably complete implementation distributed with full sources under the standard GNU public licence. The system will allow implementors, educators, and software professionals to experiment with the new language at the earliest possible time. Since ANSI Ada/83 is, with very few exceptions, a subset of Ada/9X, the GNU/Ada system will be able to process and correctly execute Ada/83 programs as well as Ada/9X programs. Two major releases of the system are scheduled, at staged levels of functionality: one in June 1993, and the second at the end of calendar 1993. We are establishing an external mailing list for distribution of GNAT documents and design information. If you would like to be on this distribution list, please send e-mail to gnat-request@cs.nyu.edu. 7) Is Ada a registered trademark of the US government? (from the AdaIC) No, but it used to be; there's a "certification mark", though, which is to be used only for validated compilers. Prior to November 30, 1987, the name "Ada" was a registered trademark. In the December 1987 issue of the Ada Information Clearinghouse Newsletter, Ms. Virginia Castor, then Director of the Ada Joint Program Office (AJPO), announced that the Department of Defense would thereafter rely on a certification mark instead of a trademark. (The certification mark is a Pentagon-shaped symbol with a "Validated Ada" message, and can be seen on the documentation of validated Ada compilers.) The text of the 1987 AJPO announcement is available as an AdaIC file (trademrk.hlp.25Apr91) in the public/ada-info directory on the AJPO host (ajpo.sei.cmu.edu). 8) I have seen the language name capitalized as ADA, as well as Ada. Which is right? (from drew@verdix.com (Drew Johnson)) The correct capitalization is Ada. It's a proper name, for Ada Lovelace (1815-1852), who is regarded to be the world's first programmer. Using all-caps usually implies an acronym, and we are not talking about the American Dental Association :). 9) What is Ada 9X? (from drew@verdix.com (Drew Johnson)) Ada 9X refers to the revised version of Ada. (Ada 83 is the current ANSI/ISO standard.) The Ada 9X Project Office is responsible for the revision, and is working closely with the international community to ensure Ada retains its ISO status. The Ada 9X process is very open. Volunteer Reviewers are welcome and should contact ada9x-vr@ajpo.sei.cmu.edu. Many draft documents are on-line on the Ada 9X bulletin board, 1-800-Ada9X 25. For further information contact the Ada 9X Project Office, PL/VTET, Kirtland AFB, New Mexico 87117-6008. Ada 9X includes three major areas of enhancement: support for object-oriented programming, programming-in-the-large, and realtime systems. A great deal of attention is being focused on transitioning to Ada 9X. The validation test suite will be available early (in draft form prior to ANSI/ISO approval with official release 3 months after ANSI/ISO approval). However, for a two-year period vendors will be able to focus on enhanced areas of the language that their customer base wants first; i.e., the first validation test suite will be modularly constructed. Vendors are also being encouraged to release beta-versions of their Ada 9X implementations prior to validation. There will also be a GNU Ada 9X compilation system available in late 1993. 10) What is Anna, and where can I get it? (from drew@verdix.com (Drew Johnson)) Anna is a language for formally specifying Ada programs. It extends Ada with various different kinds of specification constructs from ones as simple as assertions, to as complex as algebraic specifications. A whole lot of tools have been implemented for Anna, including: 1. The standard DIANA extension packages, parsers, pretty-printers. 2. Semantic checker (very similar to standard semantic checkers for programming languages). 3. Specification analyzer -- this is a tool used to test a specification for correctness before a program based on the specification is written. 4. Annotation transformer -- this transforms Anna specification constructs into checks on the Ada program that is developed based on the specification. This tool is currently in the process of being enhanced so that it can handle at least all the legal Ada programs in the ACVC test-suite. 5. Runtime debugger -- The instrumented program output by (4) can be run with a special debugger that allows program debugging based on formal specifications. All tools have been developed in Ada and are therefore extremely portable. Anna has been ported to many platforms, details of which can be obtained from the person who handles Anna releases. You can send e-mail to anna-request@anna.stanford.edu for answers to such questions. Actually, there is also a mailing list -- anna-users@anna.stanford.edu. Send e-mail to the earlier address if you want to get on this list. One could view Anna and its toolset as a *very* significant enhancement of assertions that are provided in languages such as C (using the assert statement). The enhancements are in the form of both (1) many more high level specification constructs; and (2) more sophisticated tool support. However, there are those who would not even wish to compare Anna with C assertions! :-) The Anna tools may be found on the machine anna.stanford.edu in the anonymous ftp directory pub/anna. 11) What is DRAGOON, and where can I get it? (from drew@verdix.com (Drew Johnson)) DRAGOON is a language, implemented as an Ada preprocessor (i.e., generates pure Ada). DRAGOON supports the development of Ada in a truly object-oriented manner, including complete support for multiple inheritance. A very nice feature of DRAGOON not found in many OO languages is the concept of "behavioral" inheritance. This allows you to keep the concurrent behavior of object separated from the object class hierarchy. The book by Colin Atkinson, "Object-Oriented Reuse, Concurrency and Distribution: An Ada-Based Approach" (ACM Press, 1991, ISBN: 0201565277), is very well written and describes the language succinctly and completely. For a copy of the preprocessor, you can contact: Mr. Andrea Di Maio TXT Ingegneria Informatica S.p.A. Via Socrate, 41 20128 Milan, ITALY 0039-2-27001001 12) Does anyone have a list of commercial Ada projects? (from the AdaIC) The Ada Information Clearinghouse maintains a list of Ada projects that have submitted information for the AdaIC's Ada Usage Database. It is only a sample of Ada projects, but it includes both commercial and government-related projects. Details on contacting the AdaIC are below (question 15). 13) Are there versions of lex and yacc that generate Ada code? (from drew@verdix.com (Drew Johnson)) The Arcadia project produced aflex and yacc, that are written in Ada and produce Ada code. These can be found in the STARS repository (source.asset.com -- see below), as well as other sites. 14) What ftp sites exist that contain information about Ada or Ada source? (from drew@verdix.com (Drew Johnson)) Ada Software Repository: wsmr-simtel20.army.mil Internet address: 192.88.110.20 Mirror of Ada Software Repository: wuarchive.wustl.edu Internet address: 128.252.135.4 AJPO and AdaIC repository: ajpo.sei.cmu.edu Internet address: 128.237.2.253 Source for aflex and ayacc: liege.ics.uci.edu (~ftp/pub/irus) Internet address: 128.195.1.5, 128.195.13.1 European Repository: cnam.cnam.fr Internet address: 192.33.159.6 STARS (Software Technology for Adaptable, Reliable Systems): source.asset.com Internet Address: 192.131.125.10 Unisys/STARS source: stars.rosslyn.unisys.com Internet Address: 128.126.164.2 15) What organizations exist that deal with Ada and Ada issues? (Long) (from AdaIC) Ada Joint Program Office (AJPO) The AJPO is part of the Department of Defense; it facilitates the implementation of the DoD's Software Initiative (Ada) throughout the Services, and maintains the integrity of the Ada language. (The AJPO sponsors the AdaIC.) The address is: Ada Joint Program Office The Pentagon, 3E118 Washington, DC 20301-3081 703/614-0208 (autovon 224-0208) fax: 703/685-7019 The current Director and Deputy Directors are: Director: Dr. John Solomond (solomond@ajpo.sei.cmu.edu) Air Force Deputy Director: Maj M. Dirk Rogers (rogersd@ajpo.sei.cmu.edu) Navy Deputy Director: Mr. W. Currie Colket (colket@ajpo.sei.cmu.edu) Army Deputy Director: vacant Ada Information Clearinghouse (AdaIC) (from adainfo@ajpo.sei.cmu.edu (Michele L. Kee)) Ada Information Clearinghouse c/o IIT Research Institute 4600 Forbes Boulevard Lanham, MD 20906-4320 1-800-AdaIC-11, 703/685-1477; fax: 703/685-7019 The Ada Information Clearinghouse (AdaIC) provides a full spectrum of information on Ada to anyone interested in finding out more about the programming language. IIT Research Institute operates the AdaIC for the Ada Joint Program Office (AJPO). The AdaIC publishes a quarterly newsletter, which contains current news, Ada conference reports, announcements from the AJPO Director, and articles on projects using Ada. If you would like to receive a copy of the AdaIC newsletter, please call and request a subscription. There's no charge. The AdaIC also regularly updates and publishes more than 70 separate information flyers. Flyer topics include: Ada Validated Compilers Ada News and Current Events Ada Usage Ada 9X Project On-line sources of Ada Information Ada Bibliographies Ada Compiler Validation and Evaluation Resources for Ada Education and Training Ada Software, Tools, and Interfaces Ada Regulations, Policies, and Mandates Ada Historical Information One of the most commonly requested flyers is the Validated Compilers List. This list, which is updated monthly, contains Ada compilers that have been validated by the AJPO. For the most current information on validated Ada compilers, contact the AdaIC. *Practically all AdaIC flyers are available via anonymous ftp from the AJPO host (ajpo.sei.cmu.edu, in the public/ directories).* Association of Computing Machinery's Special Interest Group on Ada (ACM SIGAda): SIGAda's bimonthly publication is Ada Letters: Non-members $37; (Annual ACM membership dues, $71; students, $21). $15 per year to ACM members; $10 per year ACM student members. Association for Computing Machinery, Inc. 1515 Broadway New York, NY 10036 212/869-7440 SIGAda also has a number of committees and working groups on a variety of topics. ISO Working Group 9 (ISO-IEC/JTC1/SC22/WG9): This is a working group that deals with Ada within the Internation Standardization Organization. Within WG-9, are several Rapporteur (rap) groups: CRG: Character Rapporteur Group - International Character Sets RRG: Real-Time Rapporteur Group - ExTRA NRG: Numerics Rapporteur Group - NUMWG packages SRG: SQL Interfaces Rapporteur Group - SAMeDL IRG: Information Systems Rapporteur Group - Decimal Arithmetic XRG: Ada 9X Rapporteur Group Ada Rapporteur Group (ARG): (from Goodenough@SEI.CMU.EDU) This is the group responsible for evaluating comments on the Ada standard. Officially, the group is only developing a technical report addressing comments and questions concerning the ISO standard for Ada. (Arcane ISO rules prevent the ARG or WG9 from issuing "official" interpretations of a standard.) In practice, when a response to a comment is approved by WG9, the response is taken into account by the Ada Validation Office and affects the test suite. The documents containing comments on the standard and ARG responses are called "Ada Commentaries" and are given numbers of the form AI-ddddd/vv, where vv is a version number. Comments and questions about the Ada standard should be sent to ada-comment@ajpo.sei.cmu.edu, using the format specified in the Ada standard. You can receive e-mail notification of an update to a commentary (optionally including the text of the commentary) by sending a request to ada-comment@ajpo.sei.cmu.edu. Commentaries are generally updated only a few times each year. The text of all commentaries is available by anonymous ftp from the AJPO site in the account public/ada-comment. A detailed discussion of ARG procedures and the format of commentaries can be found in the ada-comment account in the file arg-procedures.doc. A reformatted copy of the Reference Manual that includes WG9-approved commentaries is available from Karl Nyberg (karl@grebyn.com). Uniformity Rapporteur Group (URG): (from emery@d74sun.mitre.org (David Emery)) Responsible for evaluating Uniformity Issues (UIs). UIs specify/recommend specific choices for the compiler implementor, where the language permits implementation freedom. The "canonical example" is UI-8, on integer types. This UI recommends that integers be at least 32 bits, and provides names for the other predefined integer types. The goal of the URG and the UI's is to further Ada portability by providing uniform implementations of implementation-dependent features commonly used by Ada applications. 16) What cheap (<500$) Ada compilers are available? What follows is absolutely *not* exhaustive, but inexpensive compilers are available, and some vendors offer educational discounts. Among those offering educational discounts are Alsys, DDC-I, Encore, Harris, IBM, Irvine Compiler, Meridian, PSS, Tartan, and TeleSoft. Meridian Among choices for inexpensive compilers, Meridian offers one for $99. (Meridian Software Systems, 10 Pasteur Street, Irvine, CA 92718; contact: Jim Smith 800/221-2522, 714/727-0700) Alsys (US pricing only): FirstAda for 286 DOS is $595. It'll run on 286 and higher, and will generate applications for any x86 PC. Comes with a full toolset. Alsys does run specials on it periodically. Call Scott Dorman at 617/270-0030 for more info. Alsys offers the same compilation system for $144 to qualified educational institutions under its LEAP program. The program also offers substantial educational discounts on other Alsys products, as well as site license arrangements. Contact Kathy Ruggiero at 617/270-0030 for more info. 17) Are there any dialup BBS systems that deal with Ada? AdaIC BBS: (US) 703/614-0215 AUTOVON: 224-0215 Ada 9X: (US) 800-Ada9X25 301/459-8939 (from olender@CS.ColoState.EDU (Kurt Olender)) AdaNet BBS: This is a free service that maintains e-mail connections for people not on the internet, an Ada source code repository, and a selection of other on-line Ada-related documents. It is sponsored by NASA. Call 800/444-1458 to register for access. (from carlsons@ajpo.sei.cmu.edu (Susan Carlson)) (Caveat: Telephone numbers can change without notice.

X-Windows? Others? (See 22 and 23 for specific reference to POSIX.) General The AdaIC (question 15, above) has a report on "Available Ada Bindings". It can be ordered in hardcopy as flyer S82, and it can be downloaded from the AdaIC Bulletin Board (703/614-0215) as BINDINGS.HLP. It's also available by anonyomous ftp on the AJPO host (ajpo.sei.cmu.edu). X-Windows (from drew@verdix.com (Drew Johnson)) This question turns out to be pretty darn hard to answer easily. There are at least three variables that need to be filled: 1) platform where you are going to be running. 2) compiler you would like to use. 3) Level/flavor of X you would like to run (e.g., just need bindings to Xlib, want Openlook as opposed to Motif, etc). Once you fill all three of the above, then you can start to get answers. In order to keep the answer brief, I am simply going to list companies that offer such products, and locations where free versions are available. Before I give the list, I think a little history is in order. The first Xlib bindings that were publically available were done by SAIC for STARS. This implementation had many bugs, but it was there, and it was free. I believe that this version was eventually withdrawn from the STARS repository, and has now been replaced with a better one. In addition, SAIC has done an Xt implementation based on these Xlib bindings (also for STARS). NOTE: the above description may well be inaccurate, and I welcome corrections. Now, for the list. NOTE: this list is currently "off the top of my head", and I welcome the addition of details and/or corrections. I currently don't have time to go back through the comp.lang.ada archives to get full contact info on the companies I am listing below.
