I only discovered org-mode a couple of weeks ago, so apologies if this
is a FAQ, or the patch is in the wrong format.
I would like to define an agenda command to show TODO items in the
context of the projects to which they belong, like this:
todo: .Widget project
todo: ..TODO Gather widget requirements
todo: .Gadget project
todo: ..TODO Plan the end of project party
That would be a search like:
(LEVEL=2) | (/TODO)
But LEVEL=2|/TODO is interpreted as (LEVEL=2|) & (/TODO)
because / has the lowest precedence.
/TODO|LEVEL=2 treats LEVEL as a TODO word instead of a tag.
Is there any way around this, short of implementing parentheses?
One possibility might be to make operators that are like / but bind most
tightly, one to say "this is a todo keyword" and one to say "this is a
tag". For instance, if \ was like / but high precedence, and % was the
opposite of \, my query would become:
\TODO | %LEVEL=2
Having looked at the code, that looks almost as hard as parens.
Next idea: since "/" means "and this TODO expression", add "\" meaning
"or this TODO expression". So my query becomes:
LEVEL=2\TODO
This is a lot easier to implement. In fact, this patch does it:

Hi Peter,
as you have seen, changing the logic is not easy, for a number of
reasons.
I would like to have parenthesis, but since the parsing is done by
string processing, any parenthesis in one of the search strings would
be difficult to handle.
Some work-arounds:
1. Have you thought about using a sparse tree? Or is you stuff in
different files?
2. You could use categories to mark the entries. Basically make each
project its own category.
3. Have you tried follow mode in the agenda? Then you will always
see, in another window, the embedding of the entry you are looking at.

All the things I'm interested in for this are in one file, so that would
work. It would need a regexp that duplicated some of the logic to match
todos and tags, I guess.

Yes, that's a definite possibility.

Yes, or just hitting Space. This works nicely, thanks!
Another thing I've done is to add a TODO type called PROJECT. That also
makes it easy to put projects at different levels in the tree, which is
good because I have a huge file of things to do that I had been keeping
in outline-mode, and this is a lot easier than moving all the
project-type subtrees to level 2.

It does, thanks!

No, there are many ways to build a sparse tree, and one is a tags
query. This is
on `C-c / T' (or, if you have an old version, maybe on `C-c \'.

Yes, I have the same thing in my setup.

Have you considered using Lisp syntax, perhaps as an alternate?
Benefits include: trivial to parse (no parsing at all -- let Lisp
parse and maybe even eval for you!), easier for the user to remember
(for some of us :)), orthogonal, easy to extend (even with
user-defined functions), easier to quote and escape, consistent,
standard, free of precedence lists, proven technology,
pretty-printable, print-readable, etc.
The old syntax can easily be converted to sexp, thus separating syntax
from semantics and ensuring that the behavior is the same -- without
making anybody have to switch.
Just a possibility.

Hi Samuel,
yes, a general Lisp syntax is certainly a good idea. In fact,
currently the match is also converted into a Lisp form. However, it
does not use simple variables that would be great to supply in a user
form. The reason is that I am trying to minimize parsing for
properties and tags, so that these are only located if used. Still, I
guess you are right that this is a relatively simple extension to make
- I will think about it.
