Getting Error in ProcessTags? about taglisttoo

[ervandew]

Thanks for the bug report. I spotted the issue in the cpp Parse function and checked in the fix.

Hi, Eric. Thanks for the quick fix! It's not giving the error anymore, but in .cc files it still does not seem to show nearly all of the tags and there are some other issues. Here they are:

Issue 1. For .c (and .cc) files, most tags are not shown in the window:

trivial.c | 1 #include <stdio.h>
| 2
macro | 3 void bar()
FOO | 4 {
~ | 5 }
~ | 6
~ | 7 int main(int argc, const char *argv[])
~ | 8 {
~ | 9 printf("hello world\n");
~ | 10 bar();
~ | 11 return 0;
~ | 12 }
~ | 13
~ | 14 #define FOO wtf
~ |~
~ |~
~ |~
~ |~
2 [TagList][-][taglist,unix]> 1 trivial.c[cpp,unix] 0x0 2,0-1 All

Issue 2: for a .h file, while most tags are called out, most class members are called out twice, once specified as class members and once not. See, in the below, there is quux and Trivial::quux both called out, but they are the same thing.

trivial.h | 1 class Trivial {
| 2 public:
Class2 : class | 3 Trivial();
prototypes | 4 int baz();
Class2::myFunc | 5
myFunc | 6 private:
| 7 void quux();
Trivial : class | 8 };
prototypes | 9
baz | 10 class Class2 {
quux | 11 public:
Trivial | 12 void myFunc();
Trivial::baz | 13 };
Trivial::quux |~
Trivial::Trivial |~
~ |~
~ |~
~ |~
2 [TagList][-][taglist,unix]> 3 trivial.h[cpp,unix] 0x3B 12,18 All

For reference, here is my ctags output for both files:

┌─[john@johnmac] - [/mnt/soporifix_vol3/user/home/john] - [2012-02-07 02:22:41]
└─[$] <> ctags -f - trivial.h

FOO trivial.c /^#define FOO /;" d file:

Thanks so much for the great tool!

So far I can't reproduce the issues so, using those same files, can you post the output of the following:

$ ctags -f - --format=2 --excmd=pattern --fields=nks --sort=no --language-force=c --c-types=dgfsutv trivial.c
$ ctags -f - --format=2 --excmd=pattern --fields=nks --sort=no --language-force=c++ --c++-types=cdgfnpsutv trivial.h

And lastly can you post your ctags version and os (looks like you're on a mac, which version?):

$ ctags --version

The latest commit (296931d) should hopefully resolve the issue. It looks like you have some default options in a ~/.ctags, or some other supported file, which were resulting in modified ctags output.

[jsholmes]

Awesome. That fixed those problems! There's one issue remaining that's getting me:

If I have a .cc file with multiple classes defined within it, only the class names show up in the tag list, not the individual functions:

example: With only definitions for Trivial member functions, this works:
trivial.cc | 1 #include "trivial.h"
| 2
Trivial : class | 3 Trivial::Trivial() {
function | 4 }
baz | 5
quux | 6 int Trivial::baz() {
Trivial | 7 return 0;
~ | 8 }
~ | 9
~ | 10 void Trivial::quux() {
~ | 11 }
~ | 12
~ | 13
~ |~
~ |~
~ |~
~ |~
~ |~
2 [TagList][-][taglist,unix]> 3 trivial.cc[cpp,unix] 0x23 1,1 All

As soon as I add a definition for the Class2 function, this fails:
trivial.cc | 1 #include "trivial.h"
| 2
Class2 : class | 3 Trivial::Trivial() {
| 4 }
Trivial : class | 5
~ | 6 int Trivial::baz() {
~ | 7 return 0;
~ | 8 }
~ | 9
~ | 10 void Trivial::quux() {
~ | 11 }
~ | 12
~ | 13 void Class2::myFunc() {
~ | 14 }
~ |~
~ |~
~ |~
~ |~
2 [TagList][-][taglist,unix]> 3 trivial.cc[cpp,unix] 0x7D 14,1 All

Here's the ctags output for the full file with both definitions:

ctags -f - --format=2 --excmd=pattern --fields=nks --sort=no --language-force=c++ --c++-types=cdgfnpsutv trivial.cc
Trivial trivial.cc /^Trivial::Trivial() {$/;" f line:3 class:Trivial signature:()
Trivial::Trivial trivial.cc /^Trivial::Trivial() {$/;" f line:3 class:Trivial signature:()
baz trivial.cc /^int Trivial::baz() {$/;" f line:6 class:Trivial signature:()
Trivial::baz trivial.cc /^int Trivial::baz() {$/;" f line:6 class:Trivial signature:()
quux trivial.cc /^void Trivial::quux() {$/;" f line:10 class:Trivial signature:()
Trivial::quux trivial.cc /^void Trivial::quux() {$/;" f line:10 class:Trivial signature:()
myFunc trivial.cc /^void Class2::myFunc() {$/;" f line:13 class:Class2 signature:()
Class2::myFunc trivial.cc /^void Class2::myFunc() {$/;" f line:13 class:Class2 signature:()

Latest commit should resolve that issue as well. Thanks for the good bug reports!

[jsholmes]

It works! Thanks so much. Now to start with the feature requests... ;-)
