Just send them to me (or the list) when you are done. These can
easily be included. The custom one are a bit more difficult:

This won't be very easy to do, we'll have to figure out the best way
to do it in terms of making sure the user stays up to date with newer
versions of the bundle. We could tell you how to edit the language
grammar to add these things, but that's not very easy to do and
results in the user having local modifications to the bundle which
might result in them not seeing any official changes that happen to
the grammar.

One thing that can be done now, is that you can create a new language
that basically has the extra commands, and then includes the latex
language, and you would be using that new language instead. I could
offer a template language and tell you what you need to edit where.
However, I would consider that only a temporary fix, because my
understanding is that the next major version of TextMate will have
tools that will make this customization process a lot easier/powerful.

That's exactly why I advocate the use of .

However I did add yesterday marginpar as a separate scope. It is meta.paragraph.margin.latex (not meta.paragraph.marginpar.latex as I mentioned in my last email). >> >>> (iv) Use input instead of include when dragging a .tex document >>> into another: afaik include is deprecated and input is preferred >>> instead.

[http:// www.eng.cam.ac.uk/help/tpl/textprocessing/teTeX/latex/latex2e-html/ ltx-245.html] I was actually thinking, that one could simply duplicate the include drag command, and have a new one with input. Now, when you drag a file, you would be getting a menu with two options, and selecting one of them (with arrows or 1/2 numbers) would do the corresponding thing.

I was just looking at: http://authors.aps.org/revtex4/auguide.ps
Section 6.4 explicitly mentions using $,$ for unnumbered
equations. And nowhere is it mentioned that $$,$$ should not be used
(though it does mention \$).

The AMS-LaTeX guidelines do make it clear that both options are fine:
[ftp://ftp.ams.org/pub/tex/doc/amsmath/short-math-guide.pdf]

The only thing they discurage is the use of the eqnarray environment.
They also recommend not using $$..$$

Working on it. Actually the grammar will undergo a series of changes
in the next couple of weeks probably.

I've just added command for part, chapter, paragraph, subparagraph.
The triggers now are:

part -> part
cha  -> chapter
sec  -> section
sub  -> subsection
subs -> subsubsection
par  -> paragraph
subp -> subparagraph

Also, all these commands now create the (fold) (end) comments
described earlier, so they would fold and that should keep Jenny happy.

Further, they have been designed so that you could execute them with
a selection, and then they would wrap around that selection.

This sounds more like what latexmk.pl was made for. Running bibtex is
exactly that.

I would do: select the second part of the formula: press cmd-x, move
down until out of the environment, type eq (or the right shortcut)
followed by cmd-{ to generate a new equation environment, and then
press cmd-v.

Alternatively, you can again select the second part of the formula,
use ctrl-cmd-down arrow to move it out, and then use shift-ctrl-cmd-W
to wrap it in a new environment.

The advantage of the second method is that it does not affect what is
in the pasteboard.

That is a good idea. Please suggest a list of specific howto topics.
I'll see if I can also do a screencast demonstrating a typical
complete workflow.

I guess that's why we have the outline at the very beginning, which
links to the subsequent sections. In the first draft of the help
there was such a thing, but then it was removed. We were trying to
keep the size of the LaTeX file a small as possible, so that users
could actually read the entire thing.

necessary information, in the form of a pdf?

Allan and I both agree with that. This is something that's missing.
However, a lot of the customization of the LaTeX bundle should be
done via the LaTeX Configuration file instead. What kinds of
customizations did you have in mind? Things like creating a new
snippet or a new command, or changing a current command? Or more deep
things related to the syntax?

I take it you have seen the posts here: http://skiadas.dcostanet.net/
afterthought/list-of-my-textmate-pages/
They are a bit outdated I must say, need some new ones. Not sure if
they count as HowTo's.
