Hi,

I'm trying to add menu items in tcl like this:
(setq tcl-imenu-generic-expression
      '((TestCases  "^aetest::testcase -tc_id \\([_-A-Za-z0-9+]+\\)[
]+{" 1)))

When I turn on the major mode (tcl-mode), I get this error:
"Wrong type argument: symbolp, ((TestCases "^aetest::testcase -tc_id
\\([_-A-Za-z0-9+]+\\)[ ]+{" 1))"

What am I doing wrong?

When you use in a regular expression [_-A...] this can be 
(mis-)interpreted as all characters in the range from _ to A. The 
correct description should be [-_...].

[ ]+ is unnecessarily complicated. ' +' should do the same.

{" 1))" could be misunderstood. Clarification with backslashes might be 
needed.

But I really don't know what you are trying ...

|
| Documentation:
| The regex pattern to use for creating a buffer index.
|
| If non-nil this pattern is passed to `imenu--generic-function'
| to create a buffer index.
|
| The value should be an alist with elements that look like this:
|  (MENU-TITLE REGEXP INDEX)
| or like this:
|  (MENU-TITLE REGEXP INDEX FUNCTION ARGUMENTS...)
| with zero or more ARGUMENTS.  The former format creates a simple 
element in
| the index alist when it matches; the latter creates a special element
| of the form  (NAME POSITION-MARKER FUNCTION ARGUMENTS...)
| with FUNCTION and ARGUMENTS copied from `imenu-generic-expression'.
|
| MENU-TITLE is a string used as the title for the submenu or nil if the
| entries are not nested.
|
| REGEXP is a regexp that should match a construct in the buffer that is
| to be displayed in the menu; i.e., function or variable definitions,
| etc.  It contains a substring which is the name to appear in the
| menu.  See the info section on Regexps for more information.
|
| INDEX points to the substring in REGEXP that contains the name (of the
| function, variable or type) that is to appear in the menu.
|
| The variable is buffer-local.
|
| The variable `imenu-case-fold-search' determines whether or not the
| regexp matches are case sensitive, and `imenu-syntax-alist' can be
| used to alter the syntax table for the search.
|
| For example, see the value of `lisp-imenu-generic-expression' used by

You've got an extra level of parentheses:

(setq tcl-imenu-generic-expression
       '(TestCases "^aetest::testcase -tc_id \\([_-A-Za-z0-9+]+\\)[
]+{" 1))

Also, [\n]+ would be more readable than a literal newline.

Put "TestCases" in quotes.

That's the syntax for supplying several menu levels or regexp's.
The fact that only one is being supplied doesn't preclude use of
the extra level.

Re: More imenu questions

Hi Peter,

Thanks for the regex pointers. That helps.  I'll have to give you a
little background to explain what I'm trying.

I have an in-house developed tcl package with code blocks in the
following format:

aetest::testcase -tc_id rekey {
    aetest::subtest -subtc_id test1 {
        aetest::section setup {        }
        aetest::section test {        }
        aetest::section cleanup {        }
    }
    aetest::subtest -subtc_id test2 {
        aetest::section setup {        }
        aetest::section test {        }
        aetest::section cleanup {        }
    }
    etc ...
}

So, I'm trying to create an imenu menu hierarchy which will allow me to
put them in some kind of logical order.  Here is what I have:

(setq tcl-imenu-generic-expression
 '(("Testcase"  "aetest::testcase +-tc_id +\\([-_A-Za-z0-9+]+\\) +{" 1)
 ("SubTest"  "aetest::subtest +-subtc_id +\\([-_A-Za-z0-9+]+\\) +{" 2)
 ("Section"  "aetest::section +\\([-_A-Za-z0-9+]+\\) +{" 3)))

(add-hook 'tcl-mode-hook
   (function (lambda ()
         (setq imenu-generic-expression
tcl-imenu-generic-expression))))

I hope this clarifies what I'm trying to do.  Is this the correct way
to approach it?  

TIA,

I wish someone would tell me I'm wrong but imenu doesn't support any
kind of heirarchy.  You're getting a "Section" menu that contains a
bunch of "setup" entries without any indication of which subtest it
belongs to right?

AFAIK, the best you can do is to specify () or nil for the menu names
and include the testcase/subtest/section keyword in your match group.
Obviously, then, you can't use any sorting on the imenu index because
it's only the position in the list that gives you an idea of what
groups your entities belong to.

I've been trying to find time to enhance imenu myself because I have
several modes that need hierarchy support but it's just not happening.
If someone else has done something I'll be downloading it right away
but I've not seen anything.

I haven't been following this thread, so I'm not sure what you mean by
"hierarchy". If you're looking for how to make an imenu menu with submenus,
you might look at library `imenu+.el' for an example:
http://www.emacswiki.org/cgi-bin/wiki/imenu%2b.el.

If you find anything, I'd appreciate knowing too. :-)

Speedbar provides a hierarchical framework into which you can put
things.  Semantic (or maybe cedet) provides a menu which behaves very
like imenu but is hierarchical (in that it's split into categories).

I doubt that either is quite as easy to set up as imenu, but I'd guess
speedbar would have something pretty easy.  I can't believe it would
be *that* hard to produce a custom hierarchical menu for Tcl code.

Thanks rgb,

At least it keeps me from wasting more time on this.
