LTwiki.org <> is now fixed on the front page with

roll back their destructive work.
Hello Lewis,

Some of the spammers were ferocious in their persistence, weren't
they? They seemed to have had a perplexing, particular interest
in the section on transformers. Never understood that. Perhaps
they thought that name would attract a lot of visitors from non-
techies searching for the fictitious type of "Transformer" (as
in the films).

Anyway, we have never really net-formally met. I believe I've
seen one of your email addresses over at the LTwiki, so I will
have to send you a message. By the way, I didn't have any trouble
signing up - just took a very small amount of poking around to
find the right page.

I found it much more difficult to find the specialized wiki
language help pages (most html also works at the wiki, by the
way). Perhaps I will add a direct link to the wiki help as well.

I don't think anyone needs to be a wiki language expert to start
contributing to the LTwiki as an author may just describe what the
appearance of their contribution should be and somebody else will
probably add the wiki polish if the underlying piece is compelling.
The most important thing is to write well, concise and clear.
There is a built-in editing tool set for the most common commands
(such as basic text formatting and the creation of hyperlinks),
so the mechanics of contributing soon become easy enough.

Perhaps we could set up a Help file replacement (many bits are
already in place). Many sections would likely mimic LTspice's
Help system and at least start out by heavily borrowing directly
on the existing Help, so I wonder if permission from LTC would be
required? If so, I think you be a more diplomatic choice than me
to ask Mike.

Well, people keeping complaining about Help, but so far no one,
including the complainers, has been willing or able to offer any
concrete constructive criticism. It remains a puzzle. -- a.s.
I posted a suggestion as to how we could collaborate on maintaining/improving the help document just a few days ago - Message no. 49532.

Hello,

I think we will not have any chance to enhance the original
help with tutorials. This help is intended to be a reference
only. I am sure Mike will not change that.
If we want a more tutorial like help, we would have to make our
own with e. g. Wiki where many authors can contribute.
Such a project should be preferably started from an existing
tutorial to get a quicker start.
Nevertheless, it will require somebody or a few to define the
structure and to check the contents contributed by the many
authors.

Best regards,
Helmut

This help idea sounds great. I drafted a request to 'Panama Mike' on this group, and copied that request to info@..., to copy and use scad3.pdf as a basis for a linkable, expanded help section. Nearly all of the work currently on the wiki can be linked to this help section, as well. If we get permission, I'll disassemble the help file into a section on the wiki that will serve as the stub. Hopefully others will then amplify and illustrate this help as appropriate. I'll let the group know when something is final on this request.

Any help link to assist others format their submissions would be appreciated! Your submissions, analogspiceman, are outstanding by anyone's measure... I found myself looking at your source code to see how you did some of that stuff!

Best regards, Lewis

I think keep the existing terse help in LTspice... Add web links
wherever necessary and clicking the web links will give examples,
simulations and pictures, etc.. As new problems get solved they could be
added under the appropriate heading..
Just a thought..

I agree with AG, because I hate bloated help files that take 10 mins just to find the correct syntax for a component.

The existing help file is great just the way it is. It is accurate and complete, so don't mess it up, with a wordy probably inaccurate hot linked disaster.

If a tool is required to introduce Spice to new users, then make it a completely separate tutorial, maybe with schematic / simulation screen shots. I'd suggest you try to see how other Beginner spice packages have tried to bridge the gap. TI-Tina has some tutorials, maybe the Pspice introductory tool can be modified to show LTspice methodology.

Robert, I also am very happy with Help as is. However, I am
exploring how it might be improved because so many users seem
unable to benefit effectively from Help and I want to see LTspice
become as accessible as possible.

It is accurate and complete, so don't mess it up, with a wordy
probably inaccurate hot linked disaster.
Above all, Help must remain a terse, effective reference of LTspice
commands and how to use the unique features of the software package.
That stated, Help fails to document many useful features of LTspice,
contains unnecessarily inaccessible anachronistic language (e.g.
"cards" and "decks" for starters), generally uses netlist notation
and examples while yet the standard input is graphical via the
schematic editor. This is very confusing for those (i.e., novices)
who haven't developed an intuitive ability to correlate the two.

If a tool is required to introduce Spice to new users, then
make it a completely separate tutorial, maybe with schematic /
simulation screen shots.
The LTwiki might serve this purpose, or maybe if Mike or his minions
actively solicited suggestions to improve Help it might be made to
serve both purposes. Several obvious basic improvements come to
mind and might go a long way to making Help everybody's friend:

1. Expunge all the confusing, inconsistent terminology such as
"cards", "decks" and DOS style notations.

2. Provide at least one brief example of usage for each topic in
Help. If these are not graphical, there should be a working hot
link to either a graphical example or to launch an example
schematic.

3. Even though Help defines LTspice specific terminology and syntax,
every time and everywhere such terms are used such they should be
hot linked back to their original definitions.

4. Index terms of the most common guesses made by newbies when
searching Help for commands should be listed at the beginning of
each separate Help topic.

5. Help is not complete. Too many useful, de facto "official"
features actually are stable features of LTspice, yet are still
undocumented. There is no good excuse for this.

Personally, in spite of all of the above, I don't need any of the
list improvements and quite satisfied with Help as is (anything
missing that I feel a need for, I document in the wiki).

Regards -- analogspiceman

It needs a complete re-write, but the necessary combination of skills is
extremely rare - a way to put over intricate concepts in simple language
AND a deep understanding of LTspice. I have had some success in the
first, but I am nowhere in the second.

To do the first, you have initially to forget all you know about the
product, program or application and consider ONLY what questions the
user is likely to ask. For each question, you then 'switch on' ONLY that
part of your product knowledge needed to answer the question. If you
feel compelled to add more, formulate another question to introduce the
addition.

Hundreds of questions are likely to be required. The limited lists of up
to 20 or so, offered by Microsoft and other Helps, are pitifully
inadequate. Answers should include examples wherever possible.
---
Indeed.

But, in all fairness, earlier Microsoft stuff, like their 80XXX
assembler, Qbasic compiler, and BASIC interpreter provided excellent
documentation and, samples of code.

---
In the case of LTspice, however, since the software's free, one can't
(or shouldn't) expect the authors to jump at anyone's beck and call.
