H1: General Questions
H2: Where can I get this document?
The latest version of this FAQ is available from
{{http://www.mincom.com/mtr/sdf/faq/}}.
H2: What is SDF?
SDF (Simple Document Format) is a freely available
documentation system designed and developed by
{{A[jump="mailto:ianc@mincom.com"] Ian Clatworthy}}, with help from
many others. Based on a simple, readable markup language,
SDF generates high quality output in multiple formats, all
derived from a single document source.
Supported output formats include HTML, PostScript, PDF, man pages,
SGML, POD, LaTeX, GNU Info, MIF, RTF, Windows help and plain text.
If you want to:
* publish documents or reports on the Web or in multiple formats
* maintain a large documentation suite using rule-based formatting and
hypertext generation
* embed documentation in source code or pretty print source code
then SDF may be for you.
H2: What platforms are supported?
SDF documents are plain text files which can be created on any platform.
The SDF software has been completely developed in Perl, so it
can be executed on all commonly used platforms including most variants
of Unix, most variants of Windows, OS/2, the Macintosh and VMS.
Perl 5.003 or later is required.
H2: How do I get it?
SDF is available in a number of formats from {{URL:[[SDF_DOWNLOAD]]}}.
It should also be available from CPAN, the Comprehensive Perl Archive
Network.
H2: What else is required?
To generate PostScript, SDF requires one of the following:
* the freely available {{pod2ps}} program, available from
{{http://www.oasis.leo.org/perl/scripts/textproc/pod2ps.dsc.html}}
* the freely available {{SGML-Tools}} and {{LaTeX}} packages
* FrameMaker 5.x or later
* another word processor which can import RTF.
Earlier versions of FrameMaker will generally work, but I don't
explicitly support them.
To generate PDF, [[Adobe]] {{PRD:Acrobat}} is required.
To generate Windows help, a help compiler (e.g. hcp.exe) is required.
H2: How can I learn SDF?
Generally, the best way to learn SDF is to read the overview paper
called {{DOC:The SDF Document Development System}} - it should
contain enough details to get you started. If you need further
information on the commonly used features,
read the first few chapters of the {{DOC: SDF User Guide}}.
If you already know Perl's POD format, you might want to read
the {{DOC: SDF for POD Users}} tutorial before these.
In practice, 99% of SDF documents are created by copying
an existing one and making the necessary changes. So,
once you're created templates for the types of documents
you commonly produce, things are pretty simple ...
H2: How is SDF supported?
The following mailing lists are available:
* {{EMAIL:sdf-users@mincom.com}} - for general questions
* {{EMAIL:sdf-bugs@mincom.com}} - for reporting bugs and fixes.
To subscribe to these lists, send email to
{{EMAIL:sdf-users-request@mincom.com}} and/or
{{EMAIL:sdf-bugs-request@mincom.com}} for instructions on
using {{factotum}}, the majordomo variant that manages these lists.
In short, send email to {{EMAIL:factotum@mincom.com}} with a
message body of {{subscribe sdf-users}} or {{subscribe sdf-bugs}}.
An on-line {{A[jump="http://www.mincom.com/mtr/sdf/bugs/"] bug database}}
is also available providing information on some of the known bugs and requested
enhancements.
H2: Why is SDF free?
I have always wanted to contribute a useful tool {{back}}
to the worldwide software community which has given me so many
useful tools (e.g. [[Perl]]). As there appears to be very few
documentation tools which:
^ generate high quality output in multiple formats, and
+ reduce the time it takes to produce software documentation
[[SDF]] will hopefully be useful to a large number of software developers.
Also, by being freely available, SDF should benefit in several ways.
These include more testers, more add-on tools and more design ideas.
H2: Is SDF still simple?
Arguably not. But SDF has remained simple in spirit, so the name
hasn't been changed. Maybe {{Software Document Format}} would
be a better choice, given that SDF is part mark-up language,
part programming language. Feel free to make SDF stand for
whatever you like.
H2: Why the grapes logo?
After considering a few logos with a paper/writing theme, it was
decided to follow that great software package tradition - a
meaningless logo! As an on-line documentation system is essentially
a cluster of topics linked together, I looked for something which
reflected that idea. After 10 minutes, the best I could do was
grapes, a fern or a wattle flower. After 5 seconds of
agonising decision making, the prize went to the grapes.
Fortunately, there seems to be some useful parallels:
* from a single input (type of grape), several high quality
outputs (grape juice/wines/spirits) can be generated (likewise SDF)
* grapes are quite palatable on their own (as is SDF).
Ok - it's not as sexy as a cup of coffee, but grapes, grape juice
and red wine (at least) are probably better for you. :-)
H2: How can I help?
In lots of ways:
& Tell your friends about SDF.
. The more users SDF has, the sooner bugs are found and fixed.
& Tell the world about SDF.
. If SDF has made your job more enjoyable, consider writing an
article for a magazine explaining why.
& Report bugs.
. If you find a bug, report it to {{EMAIL:sdf-bugs@mincom.com}}.
Patches are very welcome.
& Make SDF more useful.
. If SDF doesn't generate an output format you need, consider
developing an output driver for that format. Depending on your
Perl programming skills, this can take as little as a few days.
& Make it easier for people to migrate to SDF.
. Consider developing a converter from an existing format to SDF.
For example, a high quality RTF to SDF converter would be
extremely useful.
