If I remember right, the counters start at zero as defined.
I might be necessary you have to find the introduction of your counter in your style file
and redefine it there. Even it should be possible to introduce a further counter or to change the counter's name, but this is not advised to newbies.
\newcounter{thm}[section]
This defines that at each new section the counter thm will be set to 0.

Actually doing the exercise:
I thought of the `extract' package (ctan.org/pkg/extract) or some
`verbatimwrite' (ctan.org/pkg/moreverb,
quite a few packages have similar functions)?difficult
to learn?more easy instead (although not tested, sorry):
Type theorem body code in an extra file, say, thm-outs.tex.
To typeset the theorem at its "proper" place, type
\begin{thm}\label{thm:outs}
\input{thm-outs}
\end{thm}
Barbara?s xrefthm is enlightening,
yet I would prefer the following generalization
(in the document preamble?once I desired to have this!
e.g.: Thm. 2* an ?analogue? of Thm. 2 for a different setting):
\newenvironment*{var-id-thm}[1]{%
\def\thethmid{#1}%
\begin{the-var-id-thm}%
}{%
\end{the-var-id-thm}%
}
\newtheorem*{the-var-id-thm}{Theorem \thethmid}
To be used like this:
\begin{var-id-thm}{\ref{thm:outs}}
\input{thm-outs}
\end{var-id-thm}
I prepared the previous as HTML (looks finer) at
http://www.webdesign-bu.de/uwe_lueck/texhax.htm#reuse-thm
(you may find an older version with some mistakes).
Cheers,
Uwe.

Subject: [texhax] Automated package option choice possible?
Message-ID:
Content-Type: text/plain;charset=utf-8
UNRESTRICTED | ILLIMIT?
There are at least two packages that require option choices that depend on what program you are using to compile your LaTeX files:
color and hyperref.
Compile in pdflatex? You need to use the pdftex option.
Using xelatex? You need to use xetex option, and so on.
Are there other packages that have similar requirements? (I'm curious)
My main question: Is there any way of automating the choice of options?
i.e.
if(packagebeingusedtorun=xelatex) then
\usepackage[xetex]{color}
or something like that?
I know I could always centralize the choice to a single variable that gets set once,
but is there a way of getting away from setting this choice manually?
I'm guessing there is not since the packages themselves would have probably
done this already if it was possible, but I just wanted to throw this question out there...

Yes, it is, for a number of engines. The ones I know are `ifluatex', `ifpdf', `ifvtex', and `ifxetex':
http://ctan.org/pkg/ifluatex (etc.)

No, both pdfTeX in PDF mode and XeTeX are autodetected
by hyperref and graphics.cfg/color.cfg (TL and other)
DVI driver options can't be autodetected, because the
DVI program is run *after* the TeX run is completed.
> Are there other packages that have similar requirements? (I'm curious)
Lots of packages are driver dependent.
> My main question: Is there any way of automating the choice of options?
The best you can achieve is:
* TeX processors like pdfTeX in PDF mode, XeTeX, VTeX, ...
are autodetected.
* And a default is configured for DVI drivers.
Or the DVI driver is given as global option.

A package that provides autodetection and selection of drivers
would be useful, but a good design isn't too trivial.

.... and indeed there is Vafa Khaligi's `iftex'. Vafa, you should include ifvtex and a command \texengine expanding to `pdf' `ifpdf' etc. -- Cheers, Uwe.

trying to reword:
While abbreviating macros work as ?substitutions? at
compiling only, Mike wants them to work as substitions
on the source files.
One might answer that Mike just had been impressed too much
by TeX?s macro mechanism and chose abbreviating macros
erroneously when he should have used a different program
(not TeX) to perform that substitutions, ...
* such as AWK or Perl. But indeed there are scripts right for Mike?s purpose
(see http://ctan.org/pkg/PKGNAME for package PKGNAME):
* de-macro | detex | ltx2x.
* Instead, you can use functionality of certain editors:
user-defined editor commands (e.g., with Vim),
?autocompletion?; ?expansion?
(?auto-correction?, macros, variables, aliases; by shell ...)
* If you are sufficiently mad, you may even choose TeX-based substitution:
datatool | stringstrings | ted | fifindo.
The latter introduces a kind of script language
(consisting of ordinary TeX macros)
for performing multiple substitutions
(still not very intuitive at present).
* Back to ordinary use of macro files?for substitution!
I am currently using an extension of my aforementioned
fifinddo that ?copies? one file into another,
however: expanding especially chosen macros
(I am generating HTML this way for my own purposes??blog.sty?).
This could be used here, but it would need \let\foo\relax
for any standard LaTeX command that should not expand
in this process (generating a source file).
This may become useful if those source files don?t include
the LaTeX document preamble, but rather are only (parts of)
the body of the document environment.

Hi,
just as an add-on to the two above answers.
Depending on your system and your latex editor, sometimes it might
happen the editor or get confused.
Some editors try to be smart. Clicking a button to generate a pdf will
start a program which trys to figure out which steps are necessary to
generate a pdf. To shorten compiling time as much as possible (pleasant
for the user normally), it might skip steps which seems to have no
changes compared to the last compiling.
As far as I remember this is even a part of latex itself for the
pdf-generation.
However, sometimes things went wrong and an old temporary file will
remain and not newly generated. At the beginning of my LaTeX journey I
spend some hours to search for non-existing errors until I figured out
that manual deletion of the temporary files solved the problem.
Some editors have a function to delete temporary files.
Basically (without warranty) you only need
*.tex your TeX-files
*.bbl your BibTeX style file which sit somewhere else in your TeX-Path
*.bib your BibTeX data file (if you use one at all)
and all files like templates (*.cls) etc. which you copied manually into
your project folder
all other files might be deleted. They will be generated by the next run
of latex -> bibtex -> latex -> latex
Hope that helps
Torsten
CC: A backup is always a good idea before deleting files in your project
folder
