You could say the same about our old conventions, such as open-paren in column zero and function name in column zero. Projects of all sizes adopted them because they were helpful.

Simplifying conventions are only workable if they are used throughout the codebase. If you have a one-man development team that's fine but convincing a larger team to adjust their coding conventions to support one editor is generally not feasible. In any event as Eli mentioned this bug report is probably not the place to have this discussion: I'm happy to move it to an FSF discussion list if we want to have a deeper conversation. And again I don't want to discourage anyone from working on what they find enjoyable. If cc-mode can be taught to handle namespaces reasonably so much the better. But if not, there are good (free software) options available for Emacs so that's OK too.

In C++, it's largely the namespace, which is being used ever more.
Instead of writing
namespace foo {
int bar (int baz)
{
.....
}
.....
}
, people are indenting within the namespace, something like
namespace foo {
int bar (int baz)
{
....
}
....
}
. Not all the time, but a lot of the time, possibly most of the time.
This indentation inside a namespace seems like a natural way to format a
program, and people are going to carry on doing it.
The issue is how we best deal with this.

Languages are getting more complicated, and so more advanced methods of parsing them are needed!! Implementing (efficient) parsers in elisp is becoming not just more of a burden, but more unrealistic. I'm not suggesting that cc-mode stop trying to parse code completely and start relying on an LSP server to work. What I'm suggesting is that we may consider it OK for cc-mode to make simplifying assumptions about the structure of the code it uses to provide some basic indexing capability for imenu (such as, functions start in column 1). And then suggest that for users who have more complex requirements (for example their code cannot meet these simplifying assumptions) that they should investigate more sophisticated setups based on LSP (or whatever they like). Rather than spending lots and lots of resources trying to reimplement those sophisticated setups in elisp. > > The future (again IMO) for indexing and code introspection is in LSP: > > there are very good LSP servers for C++ that are free .... > > Free as in speech (not beer)?

Well, LSP is a protocol. There could be copyleft-licensed servers out there: I haven't looked hard. All the LSP servers for C/C++ I'm aware of use clang's parser on their backends. I've never heard anyone suggest that not only do we only accept free software, we only accept the subset of that software that is copyleft. I do understand that the origins and aims of clang in particular may be less than pure. It would be good if an LSP server based on GCC was created now that it allows integration directly with its parser but so far as I know no one has done that work. I don't know how feasible it is based on the interfaces GCC provides. > > .... they are very fast and can do much, MUCH more than imenu-type > > indexing. > > Could you please give some idea of what you mean by "much more"? Since they completely index the source code, they provide not just jump to definition, but they show all users of an element, they provide accurate auto-completion, they understand the language structure so they don't just do text matching but _contextual_ matching so they won't offer completions that are not valid, etc. It also gives docs for methods and members in via hover popups, and other things. You can find out more by looking at some LSP clients for Emacs: https://github.com/emacs-lsp/lsp-mode https://github.com/joaotavora/eglot The latter has some animated GIFs showing LSP clients in action. Cheers!

Sorry, I guess I should have provided more details. When I say "server" I mean in the traditional sense, of a background process running on your local system. I don't mean "service", as in Internet service. LSP stands for "Language Server Protocol" and is a public protocol (invented and driven by Microsoft, but a public effort). The goal is to split the work of indexing source code and the work of editing source code into two parts, and LSP is the protocol between those two parts. The protocol is language agnostic, so if you have a client that speaks LSP, that same client can work for ANY language for which you have an LSP server. There are (free) LSP servers available for most popular languages. More info here: https://langserver.org/ An Internet service would be quite untenable since the server is used to index your source code, and virtually no one would be interested in uploading all of their source code to some third party for indexing. Plus it's indexing your particular code so it would have to support uploading every individual developers workspace, and uploading every change to that workspace, etc. There are many free software LSP server implementations.

It is unreasonable to expect Emacs to be able to do a job as good as the language servers, because that requires to have experts on board that can implement similar capabilities in Emacs's own code, for the plethora of languages that we want to and do support in Emacs major modes. I counted at least 2 dozen programming-language we support in lisp/progmodes/, at least a dozen of them major programming languages that are actively used today to develop and maintain very large software systems. We will never be able to have the expertise about all of these languages nor resources to track their development in a timely fashion. Doing that entirely in Emacs Lisp is already inadequate for several languages, so we will have to go to C, where we have even less expertise and manpower. Therefore, supporting language servers should be an important trend in Emacs development, one of the trends that will ensure its relevance and vitality in the very near future, let alone in the long run. We should definitely want to support that. Whether that server is installed on the end-user's machine or not is a separate issue, but we will simply be unable to support modern IDE features without having an LSP client. Support for editing programs is the main feature of Emacs, so we cannot fall back too much in that department. I see your point about outsourcing some work to an external server, but I think in this case we have no other way but to support such servers, because there's no practical alternative. P.S. Such issues should not be discussed in a bug report.

However, my personal opinion is that it's likely not the most productive use of time. IMHO cc-mode should continue to focus on formatting (which is clearly no small task, but which it's very good at!) and not attempt to also get involved with indexing. The future (again IMO) for indexing and code introspection is in LSP: there are very good LSP servers for C++ that are free (I use ccls personally) and there are also very good LSP clients for Emacs (I use lsp-mode). And of course there are LSP servers for many languages which can all be used with the same LSP client. Since the servers are external (ccls is based on clang) they are very fast and can do much, MUCH more than imenu-type indexing. I honestly can't imagine working on a larger codebase without it, anymore. I don't personally use imenu but a quick search shows that there are integrations of imenu and lsp-mode available. Just my $0.02!!

What I now have is the ability of imenu to find functions, even when they are not at column zero, and to record the enclosing namespace/class/etc. of these functions. On M-x imenu <tab>, which lists all found functions (more or less), the namespace/class bit only gets displayed as needed to distinguish from other functions of the same name. The above is a bit of an exaggeration: it is not yet clean or robust code, and hasn't been tested much, but does sort of work on the files I've tried it on. What is still missing is a scanning of a function's parameters, needed to distinguish, say, a constructor with two parameters from the same with none. This is still looking a bit tricky. > Maybe this is a stupid suggestion, but I was thinking that if the issue > is performance (for ii) we could add a special function to implement the > expensive part for the functional search in C and use the C regexps. At the moment, the scanning of these C++ files is taking a small number of seconds on my (pretty fast) Ryzen machine. This is slow for imenu. I can't honestly see how we might use a C function to speed all this up. Currently, my new code is just using (c-beginning-of-defun -1) to find the next function, thus avoiding the need to write reams of syntactical analysis code, but not being fast. > Maybe it could be restrictive somehow, but if this solves a problem, > could be good enough and important for C++-mode.

Hi Alan:
Sorry for the long delay replying this.
I have been thinking on this for a while because this issue affects me
constantly as I use most of the time C++ now.
Maybe this is a stupid suggestion, but I was thinking that if the issue
is performance (for ii) we could add a special function to implement the
expensive part for the functional search in C and use the C regexps.
Maybe it could be restrictive somehow, but if this solves a problem,
could be good enough and important for C++-mode. Because namespace use
is becoming more and more extended in C++ with the new standards. And
the most common indentations are the
Probably:
1) For example it could do a first filtration for the buffer in a C
function using C regexp (with fake positives) and then filter again in
the Lisp side?
2) Or, we could just iterate the file by lines in C and then modify the
regex for the next line conditionally (which is cheaper than in
Lisp). This could create a list in C that we can then use in the Lisp
side more efficiently.
In case we figure out a nice method for that. Does it makes sense?

The problem is that the function names are not at column zero. If they
were, they'd get recognised properly. If CC Mode's imenu were to
recognise indented functions there'd be too many false positives.
This problem has actually come up before (on 2016-11-25, in a post to the
CC Mode list by Jens Kjerrstr=C3=B6m), and I then hacked up three defuns =
which
would search for functions functionally rather than by regexp. This
wasn't wholly satisfactory since (i) this searching was slow; and (ii) if
there were two functions of the same name (e.g., in different
namespaces), imenu would only find the first one in the buffer.
If you are interested, I could send you this hack, which is not all that
big. Maybe you could play around with it and make it work well.
Maybe it would be possible to bring this approach up to a usable part of
CC Mode - possibly solving (ii) by constructing a hierarchical menu, but
problem (i) would remain. In any case this would be a substantial
enhancement rather than a simple bug fix.
